Just got the car back from GMR speed in OH this past weekend. Except for the forged rods and pistons and arp hardware the motor is completely stock! Stock ls1 intake/TB/6.0L block/317 heads/rockers/lifters/z06 cam/etc. The guys did an exceptional job with the twin turbo system, motor, fuel system, clutch, installation and tuning. I can't say enough good things about GMR Speed. They went the extra mile and addressed several other issues with the car not related to the drivetrain or fuel on their own. Final numbers on pump were 725rwhp and 740rwtq @ 17psi. I'm in the process of getting a 9" rear and DS. Future plans are to get a bigger cam and methanol system to hit 900rwhp on pump!! Let me know what you guys think.

 

Awesome numbers man congrats!

 

you got any video

 

"Stock ls1 intake/TB/6.0L block/317 heads/rockers/lifters/z06 cam/etc"

Congrats man & thats really impressive #'s with stock things right there buddy

i'd like to see vid either cause 700+rwhp on dyno sounds SICK

peace

 

Guys, the vid is on videols1tech and on GMR's website if you just click their sponsor tab on the right of the screen. Used stock parts due to budget restraints. When more $ comes...ls6 intake/ported TB/comp turbo cam/methanol. Should be good for 900+rwhp on pump.

 

nice set up, i am going to be going the same route shortly, and like you was wondering who it would fair if i had to use some stock parts for now.

 

A stock motor with lower comp, forged rods and piston will do FI just fine.

 

Fricken awesome.

Now you have a badass looking ride with badass power. I'm jealous.

 

thats my exact setup. im still debating on buying the ls6 though. im hoping for 600rwhp. it will be tuned at GMR too.

 

Good choice. They know their stuff, no doubt in my mind about that.

 

Could only dream of that number...congrads...

 

i wanna see a video toO!

 

As mentioned just go to GMR's home page----->
or go to videols1tech and search GMR. Check it out and LMK what ya think.

 

why is there a MAF in those sponsor picks? You should most definitely have a SD tune with that much boost.

 

Doing the ls6 intake, throttle body and cam wil just be wasting money. Spend the money on the methanol kit to help keep you safe, but don't depend on it for high boost on low octane gas.

Getting greedy with boost can really hurt the wallet.

 

I'll take that into consideration Zombie.
Haans, the car is running a SD tune but they also put the MAF back on for fuel economy while cruising and normal driving. Everything's working just great. Couldn't be happier.

 

The MAF runs out at approx 600 RWHP after that it is all in the VE tables. We wanted to keep maximum streetability of the car, that is why we kept the MAF and still made some killer numbers
