Late Model Racecraft

It is no secret that here at Late Model Racecraft in Houston Texas we have been setting the bar for LSX platforms for the last decade. The new LT1 C7 will be no different.

LMR currently has the C7 Z51 on order, and after extensive research and development regarding a custom twin turbo system, we are excited and ready to transform the factory C7 Corvette into a supercar that will be above and beyond the rest.

We will offer 4 packages, all which will be turn-key:
1.) 750hp- Twin turbo system with factory LT1 engine
2.) 1000hp- Twin Turbo System with upgraded LT1 engine/driveline components
3.) 1250hp- Twin Turbo System with upgraded LT1 engine/driveline and fuel system components.
4.) 1500hp+(Race Version)- call for details

Wheel/Tire and Aero upgrades will also be available to add to each package!

Our packages will be put to the test on our own C7 so we can demonstrate that each has been perfected to ensure that fitment, longevity and reliability are as important as the PERFORMANCE. This new platform will be able to give you the extra horsepower you want/need, all by the touch of the boost controller button.

For more information regarding LMR's C7 packages or to get on our list for special pre-order pricing, please e-mail us at: sales@latemodelracecraft.com or call: 713-466-9900.

We have received our LT1 castings from GM and have already flowed/torn down and started grinding on them. Overall we should have numbers very soon.

Our before numbers were as follows:

Was flowed on a 4.060 bore at 28" of water with a Untouched port and valve job.

lift Intake Exhaust
.200 134 120
.300 204 164
.400 258 193
.500 291 204
.600 285 208
.650 291 210

As you can see our bench seems to read lower than others. 1 other very known shop besides us posted 318 as there stock numbers. So dont take final Flow numbers to make decision on whos is best. Flow benches are just like dynos. Used for tuning tools, and to see gains.




And now for some pictures





And now the fun part begins!

It's seems like only yesterday we were hearing about the uncrackable read only code of the C7 ECM

I'll bet this option makes a few people reconsider their "no C7 for me" stance.

I'm happy with my z06... I'm happy with my z06... I'm happy with my z06. I'll just keep repeating that until I forget about this thread lol.

Ill take number 2 if its 1000 wheel hp

Those heads look really nice! I bet the raised intake runner will have great performance.

Sooo...

Your "offering" a package for a car that has not yet even been sold to the public? With zero testing? Zero idea of reliability? Zero real world results?

I know you guys build some top notch stuff. But I would say this is a bit premature...

Looking forward to seeing the 1500hp version.

SBCGENII

I bet they can test the heads on the 2014 truck motor. I'm sure there are some porters out there that can do a pretty good job just from previous experience. I do agree with you to an extent breecher.

at least late model is admitting there is still work to be done on the tuning side.

come on over to my thread and check out the vendors saying they had the computers and tunes figured out since day 1...

even tho HP tuners admits they still have work to do.

Must be nice to own a performance shop with a crew of spare hackers sitting around

How are you guys planning to fuel these 1000+ Horsepower builds, seeing as the LT1 is direct injection?

Dragracer_Art

Looks like HP will be limited to how well 4 studs will hold a head gasket.

irun4cops

elaborate.

What makes it more difficult than fueling a non DI motor?

irun4cops

Its a shame chevy hasnt come out with a 6 stud motor as an option. That would be something.

an LTX made out of aluminum would be nice this time around.

Gabbiani

Price and availability to start.

The stock direct injected system is usually good to well beyond the factory power but once you pass it what do you buy? We have a dozen options for injectors on gen2-4. There aren't options yet for after market DI injectors. I haven't seen an Aeromotive 2000psi pump either.

As far as being early. I think they are right on target. If they waited six months you would complain they are behind the curve. There are a lot of new parts to the gen5 but in the end it is still a pushrod ls. There are some minor details to flush out but they have already built those power levels on the previous generations so are quite capable of doing it on the next.

PowerLabs

Simple: Where are you getting your injectors from?
How about your fuel pump?

Also, in response to Gabbiani, with more stringent emissions standards the headroom in fuel injector capacity has been cut dow progressively over the years so they are not running in the non linear region of the flow curve during low load operation, so while it may have been possible to pick up 30% + power on the stock fuel system in the past, that might not be the case any more...

Gabbiani

^^ Exactly why I'm not guessing on any specific numbers.

irun4cops

my gut from day one, and plan... was to simply put turbos on the car, intercooler, turbo headers, leave the heads alone, run pump 93 gas, and put really light springs on the turbos, so i only build like 4 lbs of boost.

But use a big enough turbo for later when i want to make 15psi, and supporting parts are avail.

In your opinions, will the stock fuel system be able to support lets say 700hp?

My gut says yes. Even if its only 600 hp... ok, so its 600. Still faster than stock.

i limit boost to those levels.

Then i hurry up and wait for better injectors to be invented, etc.

The reason why i am being so hard on the big shops this week...

is all this hype and pricing on packages, etc... and no one even knows yet what the stock fuel system is capable of holding.

Late model is one of the few places simply showing results, and i do appreciate that. And since it is the only thing they have to advance because its the only part in their hands, i understand completely.

I just didnt know if they had a whole car... and they were sitting there porting the heads and not looking at the other variables such as the fuel system, etc.

breecher_7

1000+ whp should not be an issue...

Factory LS9 gaskets are good to 25lbs in my experience so as long as there is a good head gasket available with head studs there should not be a problem.

Lots of peoples problems come from bad tuning.

PowerLabs

The head gasket is not the problem though; the head bolts stretch and the heads warp under pressure and that is what blows the gasket. If you had a perfectly flat surface that never moved you could probably hold 25 pounds of boost with a single layer gasket.
To that point, LS9 heads use thicker, stronger head bolts and the heads themselves are spun cast to achieve a higher casting density. It is not the same head, I would not expect it to be as strong... I'd imagine the LT1 is about as tough as an LS3, but not nearly as tough as an LS9.
