after noticing a difference in the 2 turbine wheels, i see that the 50trim turbine wheel which is a turbonetics stage 2 is actually quite a bit larger than the 57trim turbine wheel, which is a standard stage 1 garrett...now am i correct in thinking that the larger wheel has more surface area to catch exchaut gasses will have a faster spool than the smaller wheel but scrifice top end power potential?

justin rmeember that the wheel in the turbo i sent you is a t3 wheel, .48 housing

i don't think we ever talked about that...i always assumed it was a .63 A/R hosing......so whats that tell me...faster spool but less power potential?

basically the smalelr the a/r and wheel in the turbine side will make it spool faster and have less flow on the top end.
(in simple terms)
