What do you guys think of a straight T4 on a built H22? The T4 has an A/R of 1.10

WHP target is 500whp with 850cc injectors.....I dont think my T3/T04B will be sufficient

 

lag, lots of it.
if you get a smaller turbine, and at LEAST a 60-1 configuration, then you should be able to meet your goals.

 

Your redline isn't high enough for that big of a turbine housing. Get the .82a/r

 

i made 500whp on my T4 60-1 .70a/r .58exhaust

 

Thanks for your replies

what engine is this on? also, how much boost are you running to get the 500whp? and, how long does it take to spool up? thanks.

 

I would think that on an H22A, itdhould be fine....

 

This is for the street? Then it might be a little too laggy for you, try .72 a/r.

For track? Then it will be pretty good w/ 2 stepper.

GSR, 23psi, spooled fully by about 5k rpm.

 

1.10 is so huge, you would have trouble making ful boost at a usable rpm at the track, without nitrous or such.

You probably want closer to .83 (Is that right?) for a track car, and closer to .72 for a street car.
