ECS tuned LSx

I am sincerely asking the question because I don't understand.

It seems that recent twin turbo'd stock C6's are making 150 more HP & TQ to the wheels than a stock C6 ZO6.
But, I have yet to see video or timeslips of a TT C6 going much faster than a stock C6 ZO6 in the 1/4 mile.

I really believed that a Z51 coupe with a TT that is making 600/600 to the wheels would be running be running at least 136mph in the 1/4.

I just don't get it.
Someone please explain this to me.

weight and traction maybe......er not.


I'm sure some of the guys making 600rwtq are spinning clear through the 60, but I doubt it.


Then again it could just be "bad" drivers.

In my opinion, I think it's partly because the TT cars are all making 400+ torque at the wheels as early as 2500-3000 rpm, which really limits traction when you're trying to get out of the hole.
When it comes in later in the rpm band, it can be easier to control.
I've tried my car at the track, and it was very tough to drive, I spun all 1st gear, all 2nd, and most of 3rd, and that was leaving the line off idle, while trying to baby it!
I also think gearing has something to do with it.
You can pull 125 or so in 3rd in a c6 z06, which makes it a bit easier to see better mph, due to less shifting.
It's not very easy to get the max out of a big torque car like the tt cars, and I know until I get a new clutch and practice, practice, practice, like Ranger suggests, that I won't get the most out of my car.
Good tires will also help.

In the real world the average FI C6 will be faster than the average Z06 driver. My car is stock other than FI and it went faster than what Road and Track quoted at 12.3 @ 116mph.

Sure there are a couple people that can go faster but the average driver will see similar times.

Someone needs to lone Ranger their C6FI to see what he can do.

A seriously traction-limited manual-tranny car is hard to drive. Getting max acceleration out of one takes techniques, many of which are counter-intuitive.

And so (1) techniques, (2) practice,practice practice and (3) seat time doing acceleration runs are required. Few owner manage to put all three together. But those that do can get fabulous times.

Finally, Road and Track drivers are (in)famous for their inability to coax good acceleration from manual-tranny Corvettes. Regarding their 12.3 in a C6Z06, five guys in our club did 11.55 or better at a spring track rental in MD. All bone-stock on stock tires. But these drivers know how to drive and have at least 10-15 passes in their cars.

My main problem at the track was wheel hop...hopefully with the new shocks and a little luck it will be diminished or gone.

TRACTION..........I've seen a few timeslips from FI C6s making 500-550 rwhp turning high 10s at 126mph +on slicks.............before destroying the differential. I've also seen FI C6s destroy ZO6s from a roll, but the same car could not run any quicker then the Z in the quarter.

ToSlowForU

Agreed. I destroy a Z in a freeway roll but if I were to get caught at a light by one, there'd be no chance until 3rd or even 4th on street tires. I roll into mine in second and the minute the motor hits the 5 grand mark.... tires are just a spinnin'.

The C6 stock wheels and tires are considerably smaller. That in addition to the fact the C6 is 50lbs heavier. Add 90lbs for the SC and 150lbs for the TT. Could be approaching 200lbs heavier in some cases. Plus the Z06 has more of it's weight over the back. Can't remember the exact numbers but I think the Z06 is exactly 50/50 and the C6 isn't. The added weight of FI is in the front(usually) too.

WeaponsGradeTorque

I plan on attempting Rangers 3 outstanding points. With my added HP, I have a serious challenge. It sure is fun to drive from a roll, but when I see my 1/4 slips I might wish i did not mod.

To add to this topic, FI generates serious HEAT. If not accounted for or managed, IATs will cause timing to be pulled in a hurry......especially in the summer. The NA Z06 does not suffer as drastically. The naturally aspirated C6 Z06 flat out works and is engineered amazingly from the factory.

Combo and heat IMO there are two C6's same tuner same blower both a4's way difernt results.

one runs 11's the other 13's

Gears converter and tires make the 11 second one go!

But even from a roll the stock blower car is slow my 360rwhp A6 kills it 60-160.

He wants to sell it if anyone wants a great deal!

valdeztke

He wants to sell the blower?

turbo_tom

+1 on the traction/ lack there of... :o

My car sure is fun on the highway/ back roads though...

SoldSyclone

Well the car with the blower he may part it out I can check if you are realy interested.

SoldSyclone

Tom has anyone ran an APS car at the track? Any numbers out there?

turbo_tom

Yeah, there is a guy with a yellow vert making less power than me on this site somewhere... he broke 10's @ 130+ I believe.

I won't be hitting the track untill fall or when I get a built rear/axles/drag radials & wheels. The nearest dragstrip is 2 hours away, which also doesn't help me any...

Steve Snake Driver

Isn't that car an A4 with a 2800 or so stall converter?

bowmanized

On Vetteweb there was an article about a DTE APS install on a stock C6 that ran 10.98 @130mph on drag radials through high flow cats.

DTE Powertrain

That's correct. Here are the links to that car~

I only had the opportunity to make two, lone passes in that car that day before I had to turn it over to the anxiously awaiting customer who was attending the track day, so he could have a few chances to run run it also before the day was up. He was just chomping at the bit to get behind the wheel...

Even on that "best of" 10.89/129 pass, (which isn't really that fast for this car's power) the car hooked cleanly at the launch from nearly an idle, broke loose again and spun *VERY* hard at approx. the 120" mark when the turbos came online and I just drove through the spinning- keeping it straight the entire time until it hooked back up again. After all of that sillyness, it *STILL* ran a 10.89 @ 129 w/ only a lousy 1.717 short time...

I just wish I would have had more time to spend with the car to sort out the launch so we could really see what it was capable of. I suspect that there was a tenth or two left in there somewhere if we could have kept the car planted.... Drag radials are a joke for anything other than a bolt-on modded car...

We've got the car back in the shop now to turn up the wick and the next time we take this thing to the track, it *WILL* be equipped w/ full Hooter slicks.

its all about putting the power to the ground. driver experience is a must. and 1.7 60 fts isnt getting traction if you got 1.5 maybe it would get better up top and not shake the tire threw the run
