Finding the limits of the lil TVS 1900... Vengeance built G8 GT 611RWHP/540RWTQ!!!
This G8 GT came to Vengeance from another shop making 464RWHP/445RWTQ... The car had extremely poor drivability and the customer was disgusted with his final #s.... After giving the shop several opportunities to find the missing HP and correct the drivability issues he finally lost hope and decided to give Vengeance a shot at cleaning up the mess.
FWIW his initial target goal was 550rwhp.
Original Modifications:
TVS 1900 Supercharger
Unknown "custom" camshaft
Unknown "custom" Stall converter
WCCH LS3 CNC Cylinder heads
1 3/4 Longtubes with "Custom" Connection pipes
Misc Pedders suspension bushings
Vengeance Racing modifications:
Update Customer TVS 1900 to Production status (Front Hub Assy)
Pulley Swap- Originally a 3.25- Now Grooved 2.8 making 11lbs
Remove Unknown cam/Install Vengeance Spec Camshaft
Remove Unknown Converter/Install Yank Converter
Remove "Fancy Plug Wires that were melting to headers"
Install GMPP Plug Wires
Remove Exhaust/Install American Racing 1 7/8 Longtubes with CATTED Connection pipes
Install Pedders Coilovers
Install BMR Trailing Arms
Build/Install Vengeance Racing Custom Surge Tank Fuel System (Supports 1000HP)

This car has a mild lope at idle, but drives 100% stock finally!!! The customer is extremely happy with his G8 GT once again!!!!!
Stay tuned for track results SUNDAY 1/31/10 weather permitting!!!
Here is the dyno graph of how the car came to us Vs what it left as..
Here is what I THOUGHT was going to be a short drivability video....

Thats a hell of an increase !!! Good job guys.
You should've gotten a little on ramp action. I'd like to have seen him hit and merge onto GA 400.

Holy crap, I'm thinking that'll leave a few GXP owners with their jaw's in their laps!
At this point what would be the most logical (or recommended) next step if he decided to go further?

Funny you should ask... Since the 1900 is out of steam we will be removing it in a few weeks and upgrading to a TVS 2300 and of course a set of Diamond pistons
Option B would be to hit it with a dry shot of N2O, but this lil blower is working too hard right now.

That's awesome! I can't wait to check out the results. I've been contemplating starting bolt-ons or just saving for however long it takes to put a blower on the car. Can the 2300 be installed safely on a stock motor or will it be too much for it?

Forgot to mention the A6 was built by RPM Transmission... We snapped a midshaft making 540rwhp
The 2300 is safe for a stock engine. We have installed quite a few on the 2010 Camaro without issue. They make an easy 500rwhp on low boost. We have turned them up to 630ish rwhp on 11lbs on stock bottom ends...

-Stock fuel pump fills surge tank
-one line that allows extra fuel that is pumped into the surge tank to go back into the main factory tank.
-Returnline supplies the extra fuel to the surge tank
-Other pumps use the fuel from the surge tank and supplies the fuel rail with fuel.
I ran one in my gt35r/s368 neon.

Surge tanks are used a lot in road race cars but are very beneficiary in high hp cars. You start out with your factory fuel pump and tank which will pump fuel into a surge tank (roughly around 1 gallon size) instead of going to the fuel rail. Once the surge tank is full it will have a line running back to the factory tank. If you see the two pumps coming off the surge that, those are the ones the supplies fuel to the rail. And after the rail will be the return line with the fuel the engine did not use. The return line will also feed into the surge tank as well. This will supply your main fuel pumps with a gallon of fuel always. You will never have starvation of pumps during low fuel situations, corning, or acceleration.

Thanks for the comments guys, yes I am very happy with my car now that Vengeance has fixed everything! I ran an 11.83 @ 120 this past weekend with traction control on and still not hooking but, the track was cold so a month from now maybe I will hook better. I think the car has an 11.0 in it now and once we do the s/c swap definitely tens! Thanks for all the good work Vengeance, nice post Ron!
