Large frame turbo guys step in please.
Here are some measurements
Exhaust housing outlet is 5" in diameter and the wheel is 88mm
Intake housing is 5" inlet with a 74mm wheel
a/r on the exhaust side is 1.34
no numbers on the intake side but I think it is .60 a/r it flares out to a v band flange that is 3"
These are rough measurements since I dont have a micrometer.
I just wanted to know if the 1.34 a/r on the exhaust is going to be too large for a stock cube motor that spins to 7500-8000rpm, car will be drag only with a th400 w transbrake, a large converter and live only at high rpm, looking to push around 20psi max at the track with race fuel.
Here are a few pics



I know that there is small cube drag only guys that push these size turbos without problem, I really hope more pros chime in here, like Veee8, Fireball, Phil99vette, Virginia Speed, ect.
Motor specs are weisco pistons 9.0:1 comp
compstar rods
compstar stock stroke forged crank
afr225 heads
victor jr intake with 90 elbow and 90mm t body
custom grind cam
I would like to see full boost from 5k to 8k while I go down the track, rear end will be 3.25 or 3.50 gears.
Turbo looks similar to this one, http://www.atpturbo.com/mm5/merchant...egory_Code=GLF

B? It’s a blob but it looks like a B
Then it says Garrett
Then on the flange it says 0k18
And on the other side of the flange it says b1298 and b097
