hey guys, quick question on this turbo real quick, how fast will it spool, or what rpms will it start whistling. and an estimate of rwhp

T67
.70 compressor side,
.84 a/r hot side Q trim.
divided housing



with these mods on the car.

stock non ported engine.
550cc primaries
1680cc secondaries
SAAR FPR (not sure if its knock off or real one but works good, *gift for my birthday from friend*)
walbro 255
93 octane gas
greddy mspec fmic
all emission removed
also: the power fc + commander ecu
stock NGK's trailing and leading

thanks in advance guys!

 

at around 18 psi

 

You will probably run out of spark, and then shortly after fuel pump. Turbo will probably make 15 psi by 4500rpms, and @ 18psi be between 450-480rwhp.

 

hey thanks for the reply!

what would your self recommend! id rather take a tip from an expert. because its a .84 q trim. should i get a bigger hot side housing, what would be the best size in your opinion,
also i have a devided t4 housing
