Custom single Turbo dyno results inside Well I finally got my car tuned last Friday night. Its a 95 LT1 bored to 355ci. Mildly ported stock heads and intake, 52mm tb, semi-agressive NA cam (I was told a stock cam would be better for my application and about another 40rwhp and 60 ft lbs of torque would be seen with a turbo cam) Auto trans, etc. All tuning was done on 92 octane pump gas, 9lbs of boost (the minimum possible) and the converter was unlocked. No dyno tricks.
Best run was 561 RWHP and 465 lbs of torque
Final tune was 554 RWHP and 460 lbs or torque with 11.2-11.7 air/fuel across the board.
The turbo set up consists of the following:
Turbo: http://www.hksusa.com/products/?id=817
Wastegate (the racegate): http://www.turboneticsinc.com/wastegates.html
Intercooler (the one for the Skyline: http://www.blitz-na.com/Blitz_Intercooler_LM.htm
BOV-Type H RFL: http://www.turboxs.com/BOV/bovproducts.shtml
Just thought I would share

I was disapointed in the torque to.

still decent power though, time for a turbo cam

Gee, thanks for all the nice comments.
It was first built as an NA car, then the previous owner decided to put a custom turbo on it. I'll get a cam one of these days.
The turbo and intercooler were off a Skyline....did not pay retail.

Sounds like you have a nice tweakable combo with room for even bigger numbers.

Its a Vig 3000 stall, they said I could see another 25-30 hp if I unlocked it but I didn't see any point in doing that.

I have forged pistons and Arp rod bolts, etc, however I have the stock rods and crank.
My fuel system is fine right now (Racetronix intank with boost-a-pump and Bosch 420 in line) but my 50 lbs injectors are maxed, I plan on getting 65's or 72's in the next few weeks.
I would love to crank up the boost, the turbo can make 32 lbs and I am only at 9 right now, but I am afraid the engine would go.
) Unlocked = LOWER rwhp. Depending on how loose your converter is, you might easily see another 20-30rwhp just by locking the converter on the dyno. What version of Winpep is your dyno using, 6 or 7?
Post up the cam numbers when you get a chance.
