994rwhp 863rwtq We were playing around with our shop car on the dyno and got some new numbers.
994rwhp 863rwtq through an (unlocked!
) turbo 400 and a full 4 inch exhaust system exiting at the bumper.
This is with a mid frame Innovative 88mm turbo, turbo system built in house.
Sportsman 370ci iron motor.
out of the box AFR 225 heads
LS6 intake, 78mm throttle body
236/242 112lsa cam
22psi boost, 23deg timing, C16 fuel
We are now disassembling the car and building a twin system

Does that downpipe neck from 5" down to 4"? That is a pretty sweet setup and great numbers.
How much more power would that T-88 put down?
What crankshaft?
What rpm is it making full boost at? and size stall convertor?

gnx7- Yes, downpipe is 5in and necks down to 4in to make it past the engine/k-member. Full boost is around 5200 on the dyno, earlier on the street. Our sportsman 370 uses an iron block, stock crank, eagle rods and diamond pistons. This is as far as we've taken this combination, if I had to guess, I would say it could make about 100 more hp maxed out.
stoleit- Thanks
gator's 99TA- TCT 4000
paspar2- As with most any turbo combination, more displacement will make the same or less peak horsepower, and more low end power and torque at a lower boost level and RPM.
We prefer 350-370ci for a turbo application. Smaller displacement will extend the usable rpm range for a given turbo, and also run the turbo in a more efficient range of the compressor map.
