Currently at 500fwhp
/ 422lbft at 1.55bar, only stopped tuning due to fuel pump going bad. The turbo i am using is the HTA version of a GT3582r which uses a anti surge housing and billet compressor wheel, like the GTX35r. 0.82ar exhaust side. I believe the standard GT35r's most efficient between 1.6~2.4bar iirc? and the HTA having the billet compressor -lighter and more surface area on the fins, is most effective between 2bar ~ 3bar ! Im hoping to get the boost up to atleast 2bar so it will put the turbo just inside its effeciency range and should produce a lot more power going from1.55 to 2bar than it did going from 1bar to 1.55 ?? thats the theory anyway. Engine is a 2.14L rev3, std cams and we will be retarding the exhaust cam slightly. My current IAT's are maxing at 41'c on dyno.Also current tune is on BKR7E's, have gone a grade cooler for this next tune.
am i being over optimistic by hoping for a 100bhp increase?
whats everyone elses guesses.
.. torque figures too
