Thank you Polo, it is a lot of fun having the ability to "play" out side of the box so to speak.

I will post more as I get the last bits put together.

Mo

That would be cool! right now I'm pretty much the mad scientist of the neighborhood... LOL

So I was able to do a little more work this weekend...
https://cimg0.ibsrv.net/gimg/www.cor...791197b3a8.jpg
Motors and controllers are in and placed. the battery chargers are to the right.
https://cimg2.ibsrv.net/gimg/www.cor...df7af43566.jpg
Controller cables are installed on the controllers.

High Voltage cables installed


I still am working out the motor mounts.

Obviously more to come!

Mo's Electric Corvette - Lot of Pictures
 

Hey Wayne, Have you had time to dress up and secure the wiring? Have you taken it out yet?

funny you should ask.

Shortly after taking this picture, I was commissioning the motors and ran into a glitch.

I called and they had shipped the right serial numbers, shipped them in the right boxes, but accidentally shipped the wrong motors.

I had to completely tear tear everything down again to ship the motors back.

So, the correct motors have shipped and are supposed to be here the 26th. So I get to repeat the process. The upside is I have gone through this once so the next time should be much quicker. At least the controllers have been programmed so it should be a matter of just commissioning the motors, finishing the motor mounts.

I will post updates once the motors arrive “ again”...

thanks!
Mo

Sorry it has been so long since an update.
It has been crazy, the new motors are delivered and installed.

Long story, short, I was commissioning the motors and apparently blew both of my shorty power glides! So after swapping two power glides, I decided I was finished with them.

So I'm going direct drive with a 1.9:1 gear reduction box with my stock 3.07 rear end. Imagine running from 0-7800 rpm in first gear! 0- 105 mph without shifting! 6.14:1 overall gear ratio.

So I will be running essentially direct drive (below). So I will have the 3 buttons shown below to Select "Park" "Reverse " and "Forward". If say the reverse button accidently gets pushed while in drive, he controller will essentially cost the motors to 0 rpm and it defeats the throttle to keep from destroying the drive train and yet allow you to safely either pull over or just reselect the forward button.

https://cimg5.ibsrv.net/gimg/www.cor...d3474ff5c9.jpg
Mine will not have the parking Pawl attached to it.




The button pictures below are inaccurate, Park will be red, reverse will be blue and forward will be green. They only have Red, Green, Blue and White Latching buttons.

The Torque Box weighs 35 pounds and is 12 inches long, so I will have to get a longer driveshaft. It looks like it may be up to an 8 weeks to get the torque box, I guess after waiting a year for the motors what's another 2 months :P

Attached are some pictures of the car thus far it is coming together.

Once again ......... really impressive. Thank you so much for sharing all of this. On your web site you might consider a darker font for the detail paragraphs; the light blue is too difficult for these old eyes to read.

Hey Mr. Peabody, Thank you for the suggestion, I actually went in and did some updates as well as darken the font. It was one of the canned pages.

Thanks again,
MO

A shame you haft to run direct drive. Seems like that would eliminate some low end performance to accommodate a respectable top end.

Keep up the great work! :thumbs:

Hey Colo63sw,

Thank you!
Actually no that isn’t the case. The motors make 340ft/lbs from 0-about 5000 RPM. Redline is 8000 rpm. The torque curve on electric motors is almost direct opposite of an internal combustion.

So it is essentially like running in low gear all the time. My Chevy Bolt is almost identical in that regard. With the powerglide my launches with first gear, I was pulling .76 G’s on launch with street tires.

With the powerglide I was running 1.80:1 the Torque Box is 1.90:1 which is of course a touch taller. I am sacrificing a bit at the top end, with the 2 speed powerglide top speed at 7500 rpm would be about 135 mph.

Actually i am fine with it, it tremendously simplifies things in regards to trans slipping and the trans pump ( because there was no torque converter).

So once the torque box arrives I will have more updates.

Thanks,
Mo

Fellow volthead checking in with a thumbs up
Contemplating a P85 rear drive with 32kw of Volt batteries in a C3. Nowhere near as much range, probably like 120 miles, but the parts are cheap and well documented by now, should make for simplified electronics.

and yeah good on you ditching the transmission, motors love to shred those things. Now you have exactly one speed: damnfast

There you are! Cant imagine that kind of tq at 1 mph...lol
The tesla pkg is interesting....love the v8 sound but to go say 10s and not replace parts in some way appealing.

That's awesome!
I was considering similar with the tesla motors, but the track width was too wide, so I decided I didn't want to go that route. However, that will be a really nice route to take!!!

I may (once I get the new system on the road) decide to pull 6 of my Tesla batteries to lighten up the car a bit, once I see what the range is going to come out at.

As you know it becomes a balance of weight and performance and range. A lot of my trips are ~ 120 miles and many times I do not have the option of topping off anywhere.

Keep me posted on your build!

Best regards,
MO

yeah, that confused me, why bother with a full model S subframe? Why not bolt up the motor/inverter (with lots of bracing) into the existing frame with custom half shafts, the old no-really-i'm-a-differential-i-swear approach.
alternatively, live the wide track life, widen the front, and go for a widebody setup, that'd be pretty gnarly

Yes , absolutely! For me it was just the lack of patience more than anything. But yes I agree that would not really be all that difficult to pull off.

Mo

Newer revelations:
if you eventually give into the tesla drive unit desire, i strongly recommend you go with a model 3 performance rear drive unit instead of an old p85 rear drive.
the M3 DU has a FAR better cooling system with a proper oil pump and heat exchanger (even has an oil filter canister so it's serviceable instead of being a closed system), the old p85 cans have a gear driven oil pump that's driven by wheel speed, so model S' would go once around a track then overheat the motor and go into limp mode but M3s will just go and go.
they're also a little more efficient so you can get more peak horsepower power out of them AND they eat less range when cruising
also they're more compact, getting much closer to the footprint of a differential, it even has something kind of like the wings on a diff
They're not really hacked yet so controlling them isn't a thing, but give it a year and i bet they'll be hacked to hell and back, working on all those fancy aftermarket motor controllers like the T-1C

Thats great information. I will have to look deeper in into it. I haven’t really looked too deep into the Model 3’s.

Thanks!

Mo

i wonder though. Reading though, you never really mentioned fighting the car's electric/computer systems to make stuff work.
Is the C4 fundamentally OK with the ECU and transmission just going poof? Did you have to do a ton of hacking with wheel speed sensors, abs, etc? Or did it all just...work?

Hey there, Jokeitch,
Initially I kept some parts of the ECU when I was running the stock transmission, I had to reprogram a lot of the shift points and other settings.

The ABS I pretty much left alone but the traction control because it was tied to the engine etc was done away with completely.

As the project continued, and I lost the stock trans the only thing the ECU was controlling was the speedometer and the tach LOL

So I completely pulled the ECU and went to a GPS speedometer and use a 4 pole sensor on the tach .
The control module in the car is still fully intact.

Many parts of the ECU are now taken over by the motor controllers which of course are still programable.

Having the service manual handy has been a major bonus, to adapt like the backup lights, the reverse lock out and a few other things.

That said pretty much everything is possible to re-adapt.

I'm actually working on installing a pushbutton parking brake since I will no longer have a parking pawl.

If you have any further questions let me know I'm always happy to help...

MO

Thanks for the update.

Now that you are in the upper midwest, will you be putting snow tires on her?? :rofl:

Thanks!!
I dun think so, skies maybe 😂😂😂

mo

Welcome to Ohio Mo... big change for you. If you ever get to Columbus, let me know.
Where in Northern OH are you. I grew up in Cleveland.

Jim

Hi Jim,
im in Fremont, Ohio.

I actually grew up in Ohio as well graduated from Sandusky.

Thank you for the invite!

Wayne

Cool! So trips to Cedar Point are back on the agenda...

Oh Yes! That would be cool!

Wayne

Guys sorry it has taken so long to respond.
As most of you know I have moved to Fremont Ohio.
It has taken some time to get settled but we are finally here, and the car reregistered and insured.

I have been able to take it out for a couple long drives, I went 165 miles on about 60% of the charge, so 200 miles is very easily achievable as I had calculated.

The 0-60 is right in the 5 second range, not quite as fast as the DC motors but it still pulls good and is faster than the stock LT1 LOL

I'm not sure how much driving I ill get to do with winter closing in, but I will probably be doing some updates that I have been wanting to get done.

I did manage to go to a local car show where the car was actually well received, I had it judged as the most unique, but I guess being ( to my knowledge) the only electric Corvette in Ohio it would have meant something, but as even in California the judges don't always agree. But I did have a blast.

I'll try to keep everyone updated on any changes I'm up to.

Thanks!

MO

wait, almost 200 miles of range? damn, that's impressive
what;s the kwh of your battery pack again?
edit: didn't notice you had it in your fact sheet, 12 tesla modules, that's 5kw each so 60kw total, but like 900 pounds of mass, oof

Thanks for the update Mo.

Yeah, that seems "good" :willy:

No actually the battery weight is 660 pounds. The car only weighs 3342 which is right at where it was stock with a half tank of fuel :)

I pulled 938 pounds out during the conversion.
Mo

938 pounds out is impressive, had no idea the c4 drivetrain was that beefy
Also i thought tesa module bricks were heavier than that, they're only 55 pounds a pop? nice
This is making me more optimistic about my c3 conversion, since i want to only add like 200 pounds to the original curb weight at most, although i'm hesitant to get tesla modules since they're bonkers expensive still. That's like 13 grand worth of battery right?

Yes they are about 50 pounds a piece and about $1400 a module. they are the most energy density though. I had 108 100AH CALB lithium's 7 pounds each, so 756 pounds and they only we good got 80 miles. The Tesla's I have the modules wired for these motors at 6S 2P so 144V and 420AH and almost 3 time the range at 660 pounds.

That might be doable, remember you are getting rid of the radiator, engine, fuel tank, exhaust and many other components. a lot depends on the performance and range you want to get... I could easily shed 300 pounds if I only wanted to go 100 miles. which would put the car at about 3040 pounds.

Depending on your motors and trans and what you want for distance, the modules could fit in the area behind your seat and where the fuel tank was, OR you could split the pack and put a few up in the front with the motors and control.

Have you considered motors etc. ?

Mo

the model 3 motor and rear subframe idea seems to be the most promising so far (graft subframe attachment posts onto the c3 frame to accept the entire model 3 rear subframe with all suspension) because the motor's really energy efficient (more range), has excellent cooling (no thermal limp mode worries), the track width matches the c3's better, and it's just a better motor design in general. Rumor says it can push 500hp with some software unlocks, and many ev tuning shops are working to crack it.

model 3 motor + DECAlink rear is an expensive close second possibility which is much less complex to fabricate, since i can stick to simple motor mounts and let the decalink handle all the suspension bits.

Yes I have been watching that as well as the P and S motors, the track was too wide for the C4 and I really didn't want to go down the road of completely redoing the frame.
Those systems were running like 22K for an out of the box solution plus they would require the 16 modules which would turn the car into a lead sled.

But yes as you said the Model 3 parts look really good, also it looks like GM is talking about electric crate motors as well. But I'm sure they won't be cheap...

MO

Yeah that's the downside to the tesla modules, it's tricky to get the 400v you need without causing voltage sag.
Hybrid system batteries like the Volt and Chrysler pacifica hybrid run at 400v out of the box and you just string them together in parallel as many times as you want for your range/weight targets.
Not sure where you're getting 22k from though, I've seen a few complete P85 rear ends with subframe and suspension for around 8k on ebay, which you then pair with very complete motor control units like the ev controls T-1C. It's not totally turn key but pretty close

EV west has the S motor complete drop in for $11,800 and figure another minimum $10k in batteries EVWEST ( that is where I was getting the $22K). Yes I totally agree there are new places popping up all the time.

Hi Guys,
It has been quite awhile since I have posted, numerous trips to Asia Pacific, and Florida.

So that said, I pulled a rabbit out of my hat !

As you know I added new AC motors to the car before moving to Ohio. Well I took numerous drives and the car felt good and excellent range.

I called my sponsor we had a discussion on how the car was running, I said "ok" but I'd like a little more "punch" the car 5 seconds was ok but I'd like a little more.

I jacked up the car and made some measurements and guess what? The tunnel was large enough for a THIRD motor... Yes a THIRD motor....

I called my sponsor and we discussed it, they were like "let's do this!" so of course it hit right about the time everything was getting locked down.

Well last week the third motor arrived along with the controller etc. So I have been a busy frog.... I had to take the driveshaft to have it cut down, it is only 19.5" ! I was able to adjust the pinion angles, but I may need to adjust some depending on the necessary preload.

The three motors combined provide 360 HP / 486 FT/LBS of torque. Estimated 0-60 3.8 seconds.

I took the car out yesterday for the first spin, I tell you, it is now really fun to drive. Very spirited. I may need to rewire my batteries as with all 3 controllers at full throttle I'm pulling up to 1500 amps. Which is in the fringe of that I can safely pull from them without blowing fuses etc. so I may need to go from 2 in parallel to 3 parallel so I can safely pull up to 2100 amps without issues and still have some margin of safety.

With the weather warming up I will be taking more drives to do ore fine tuning on the system

Thanks for the update Mo.

I don't think I've ever seen a 20" driveshaft :D

Wow, that's impressive :thumbs:

Latest road test....

Dang, video is marked private.

Open it up so we can view it :D

Sorry folks, it’s public now.

Enjoy!

Mo

So, Mo, I'm wondering if there are any updates on your project.

:D

Hi Ghlkal!
The little time I was out and able, I was able to break the car twice LOL

First time out tuning, pushing it very hard with the 3 motors I blew the main pack fuse 500A (thank goodness for AAA) LOL

Freaked out the tow truck driver LOL Always a conversation piece LOL

So I quickly fixed that problem ( replaced the fuse with a 800A fuse) , and again romped on the car I sheered one 1/4" x 1/4" key stock between motor 2 and 3 which was very interesting. I had to raise the hood and turn off motors 1 and 2 to get the 3rd motor to actually drive, and limped the car home, so I'm researching a means to strengthen the couplers between the motors.

Also I changed out the 3.07 rear end for a 2.59 rear end, now I can cruise 65 at about 3700 rpm's verses about 4800 rpm so at 60 I'm still in the maximum side of the torque curve 486 ft/lbs. Also that helped the top end raising it from about 105 to125 mph at red line (8000 rpm)

So now I'm waiting for a little warm weather to take it out again and dial in the drive angles...

Aside from that not much going on LOL

Thanks for asking!

Mo

:rofl::rock:

Thanks for the update. That is one wild ride.

you know you're slapping some serious amps when you shear the god damn intra-motor couplers

jokeitch,
Lol, yes sir, just like an internal combustion engine, you push the limits until you break something and fix it lol.

I’ve got the car back together, so once the weather breaks, out for another spin :)

Happy New Years!
Mo

It's been a while since I have given any updates with winter and weather.
My first ride out after winter it seemed like the brake booster failed and after a 65 mph jaunt dot the road and double feet on the brake to keep from rear ending a car stopped at the light, I decided some upgrades were in order.

So over winter I have been doing a few updates to the car.
https://cimg3.ibsrv.net/gimg/www.cor...f75e173d18.jpg
new front brakes and rotors
https://cimg4.ibsrv.net/gimg/www.cor...20829d91f9.jpg
new rear brakes and rotors
https://cimg5.ibsrv.net/gimg/www.cor...e3d558713d.jpg
rear wheel adapters for the new rear 285/35-19 rims

More posts to come...
Mo

In addition to the brake upgrade, and further trouble shooting I found that the brake booster in fact had failed. The Leed's vacuum pump was a nice product but the brakes never really seemed to grab as I expected them too, especially that i no longer have ABS connected.

I could have just went with a new booster, but just about every company was out of stock, so I bit the bullet and decided to go with a hydro boost brake system since since I already have power steering with my Miata MR2 Electric power steering pump.

After a month of waiting for the system to be shipped I installed it, with a new Wilwood Compact Master Cylinder with a proportioning valve system as well.

It is a tight fit, but I'm EXTREMELY happy with the results! I had to notch a corner of the hood wheel well cover.

I took the car out for a spin, a bit concerned with "having brakes" ( which is another story) but those fear were quickly put aside after a series of 30-0 mph hard stops followed by a 50-0 very hard stop.

I kid you not, these brakes will put you through the windshield ( in a good way) I don't recall ever being this good as long as I have owned the car!

Are those C5 calipers? And did you retain the rear parking brake? Although I guess that's less needed for an electric car...

Hi there, no they are the stock calipers with the Corvette covers on them 13" front rotors and 12" rears. Yes I kept the emergency brake.

Thanks!
Mo

Thanks for the update Mo. Excellent work as always :thumbs:

that's a sweet brake setup - I'm glad it's working well too

Just spent some enjoyable time going through this thread. Amazing work!

Thanks!
Mo

Thank you!
Mo

Agreed, same here. I never want to get rid of mine (at least until I can't get in/out of it) and it's nice to see that there is a future no matter what happens to the ICE.

Great work Mo, I really enjoyed the thread.

Any updates, Mo?

Live well,

Hi Guys,
Thanks for the "ping".

It's been a very busy Spring /Summer and now rolling into Fall.

I've been to about 11 car shows thus far this year, Mo Amps was featured at the last 3 shows, which has kept me extremely busy.

I also received a call from PRI, Mo Amps will be in the Torque Trends booth for the PRI show in Indianapolis Dec 9-11, 2021, so gain I have been trying to get the car ready for that show as well.

Ten years of a very cool project. Any idea what the car weighs now?

Hi Aardwolf, the car now weighs 3465. Before the conversion with a half tank of fuel it weighed 3460.

Thanks,
Mo

Impressive similarity in before/after weight, Mo. Congrats on that. You may have already posted it, but what's the front/rear balance, before/after?

:cheers:

Live well,

SJW

Yeah, that Vette _should_ draw a crowd :thumbs:


How are you getting the car to Indy in the winter time?

I was going to mention it😂. It’s 45/55 pretty much reversed of what it was stock.

mo

Im having a commercial carrier take it in an enclosed trailer. I’ll be there for pickup and delivery, before and after the show.

thanks!
Mo

if you were on the west coast, bay area, i'd say bring it to that holley high voltage event this coming weekend

Cool project, and a fellow northwestern ohioan! Bring that to a Toledo cars and coffee next year :)!

Jokeitch,
Thanks, as you probably know, I spent quite a bit of time in SoCal the past 35 years.

I'm starting to get the hang of the shows here in Northwest Ohio (where I was raised). :)

Thanks,
Mo

Thanks Pedricd!
I'll keep a watch out for it, as I'm in Fremont, so Toledo is not all that far away.
Thanks for the invite! :)
Mo

As a retired electrician, I'm impressed by the quality of your work. Top rate! I've been thinking about exactly this project for my 85 eventually, once the engine decides it needs a rebuild. In Canada, we are going to see a serious drop in gasoline availability coming around 2030, so I'm looking far into the future. I'm hoping by that time, electric replacements will be mainstream and batteries will be much more available and cost-effective.
Keep up the great work!

Livewire1,
Thank you for the compliment. Yes today compared to say 10-12 years ago parts are becoming much easier to obtain, and the battery technology keeps getting better.

Also though quite expensive they are also coming out with crate motors / systems.

If you love the car ( like I do) you will find ways to hang onto it. 😊

Thanks,
Mo

Hi Folks, sorry for the delay.
Mo Amps was VERY well received at the PRI show.

Here are a few pictures to share, over the week there were over 17,000 people attending.

Cool! Maybe a larger opening to view the batteries would show better. I've been thinking of engine swaps for my ATV awhile and see there are motor swaps available. I might have the first EV on my road with that LOL

Hey Aardwolf,
Even though the pictures don’t show it, the batteries were on display, they are about 34” x 36” seen through the rear window. That is the total size of the battery pack.

Due to safety restrictions we had to be sure that no one could potentially touch or get shocked by any high voltage. Mo

https://cimg3.ibsrv.net/gimg/www.cor...79ab9d8032.jpg
From the pictures above it's difficult to see the battery pack, but they can be clearly seeing through the rear hatch.

IC, would be a good view through hatch glass.

Fantastic. Keep up the good work Mo :thumbs:

Car looks great Mo. Glad they liked it. What's next on the agenda for the car?

Here's an interview of my conversion at the PRI Show.

I thought I would share..


Mo

Very interesting.

Thanks for sharing that :thumbs:

Seriously cool stuff, Wayne, and the execution is beyond impressive. Thanks for sharing.

:thumbs:

Live well,

SJW

Pleasure interviewing you Mo, this is Jon aka Internal Combustion. Heres a few pics from PRI

"Oh no, we Gonna Rock down to, Electric Cor-a-Vette, and then he'll take it higher!
Ho, Out in the street
Out in the street
Out in the daytime
Out in the night"

Hey Mo, any updates?

I love this project and I'm hoping you have some new goodies to share :thumbs:

Hey there!

Thanks!
Unfortunately not really much happening.

I’ve been super busy with other things going on, but the Vette is still going well and strong 😊

Thanks for checking in though…

best regards,
Mo

This Saturday, cars and coffee at Toledo Executive (NOT express) airport hosted by the EAA, awesome
event…cars mixed in with very cool old planes that fly in. Your drive onto the tarmac. It’s “invite only” since it is at an airport, and I’m inviting you :)! Let me know if you want details.

last year:

Thank you for the invite, unfortunately my daughter just moved here from CA and we are having a house warming for her this Saturday. Perhaps the next time 😊

Best regards,

Differential/Transmission Question
 

Hey Mo/Wayne,

I came across your interview at with Internal Combustion’s Youtube channel. Ive been pipe dreaming about doing an EV conversion for a while and your idea coupling Hyper 9s really blew my mind. Im not a fan of starting my first build trying to jerry rig a hacked Tesla rear end like Damien McGuire does, at least not until Im more experienced.

I was curious about your use of Torque Trends TorqueBox (1.9 reduction) coupled to a 2.59 diff. Did you consider going direct to the differential and swapping in a higher ratio ring and pinion like a 4.88 or something that gets you to the 5:1 ish ratio?

Reason I ask is Im floating that idea in my research as a way to reduce weight and drivetrain losses. My SC300 has a 4.27 which might be a little too sluggish even with 2 or 3 hyper 9s. Trying to see if theres kits out there that can bring it to 5.00 or higher.

Thanks!
Brendon

Hi Brendon,
Yes I chose the Torque Box for a couple reasons.
The Dana 36 rear end about the highest you can go is are 4.11 gears. I was actually running 3.73's when it was supercharged. So I selected the 2.59's to put the motors at about 2000 RPM @ 60 mph with the overall ratio at 4.941. It was more personal preference, the Hyper 9HV's max RPM's are about 7000 rpm's the torque curve starts to fall off at about 4300roms and they are designed to run continuous at 3600 RPM's. So as you can see it's a matter of higher top end speed, or acceleration. Even with the 2.59's I was still faster than a stock Corvette which was 5.7 seconds. I was running 4.8 seconds consistently.I also wasn't worried about overheating the motor running it at a higher RPM.
The Torque Box has a parking pawl which is essentially like putting the car in park, rather than having to set the emergency brake to keep the car from rolling.
Also I felt the Torque Box was more robust in terms of gearing as well as connecting to the rear of the motors and mounting to the frame.
Coming straight off the 1 1/8" shaft that is keyed seemed a bit scary to me as you are counting on the bolts biting into the shaft to keep everything together. Where are the Torque Box coupler and mount are very beefy and also add another mouning point to keep the motors from moving around under acceleration etc.

Gosh. I've never seen this thread before. Really interesting project. Mad scientist stuff. Ha.
