dont believe what she says, size does matter..

very intersting. helps me alot. Turbos are different to me. Always have had v-8's "american power" the supra is FUN i love it

trim by the way...
i think trim is just the size of the intake wheel diameter? mine was upgraded to 50 trim and the housing was machined to fit the larger wheel..and nothing was done to the exhaust side. i guess the exhaust side mods are not needed untill higher boost levels. 50 trim is good to about 400 hp or 15psi (the sweet spot of the turbo) where it runs most efficiently....bigger hp motors need more air and or lager wheel to flow more air..

is 400 to the ground or flywheel?

probably flywheel.. but not sure..

but sill thats lots o power. isnt 15% a general rule in drivetrain loss? still around 340 or so to ground is alot! my mach put 281 stock. with 15% should have been 255-260ish. I think i read in a car magizine 15% was a "general rule" anybody seen or heard of this?

15% that sure sounds about right if i was gonna guess

also 50 trim will make 20 psi but i think that at that boost level its working it too hard and starts to create heat and? not to mention you need octane boost for higher boost and more fuel...,, just tell em what you have now as far as mods, and what boost you want to run.. and what your future plans are as far as hp and more mods... hahahha. they will help you deicide whats best for your application...

Where did you get your Trim and impeller mods done Joel?
