My 1997 Corvette Automatic Turbo

Turbo setup custom built by me Trent Durham tuned by John Cozad / Rev Hard Inc.

Stock HP @ the crank 345
Stock HP @ the wheels 265

Turbo'd HP @ the crank 575 ( estimate figuring 25% loss with auto transmission )
Turbo'd HP @ the wheels 435

8psi, 93 octane SHELL gasoline, 100% stock 100,000 mile motor

Nice gain of 64% whp and 170whp ( supercharged c5 autos gain about 55% whp )

Most pulls and tuning are done in single gears, but especially on boosted autos, need to do some 2 and 3 gear pulls to make sure there is no knock on the shifts ( and mine did knock a little on shifts, ended up having to take timing down to 8 deg at peak tq to keep knock away ).

Pretty cool set-up you built, especially the location of your single turbo.

Some pictures of your set-up would be nice.

Good stuff, what was your final cost of this project if I may ask?

Look at the Spark Control > Knock Sensors > Knock Sensor Level > Tip in TPS table. This table is used to increase/decrease knock sensativity during rapid throttle transitions. May help you get back some of that ignition advance...

one off kits are labor intensive

but parts were about 3200, add labor in there and you dont want to know lol. I want to reproduce this kit but dont know if the interest is there, and i would want to use a better turbo than I did for the kit so price would go up some.

Well this dyno isnt a Dynojet

its a land and sea awd dyno plus you have to remember the 4l60e is one robbing hp transmission, This tranny is built to hold more power how much is my only question lol
But anyone thats been on this dyno that has been on a dynojet dont like our numbers. Remember a dyno is only a tool to calculate and measure differences when changes are applied. Reguardless of what the numbers are, only interested in the change, and afr of course
