I have a GT3076R and am looking for a Tial Vband housing. I'm shooting for 480~500whp with the Pfabrications EL mani @ 14~15psi. I was thinking about getting the .62AR for quicker spool time. I'll also be tuning boost by gear, maybe 10psi for 1st and 2nd gear. btw my car is a street car.



thanks

sounds good to me! .63.

 

Its a .63 housing, it should do just fine for the quick spool.

 

the .82 will slightly spool slower and have more potential for more hp

 

your only talking about a 2-300rpm spool difference, go for the larger AR...

 

Id get the .82 a/r housing . The boost still will build much quicker than the s/c you were running . I think the .63 a/r housing is too much of a restriction for a f20/22 engine . Do it right the first time

 

Thats what I always prefer, but some guys are set on the quicker spool.

 

.82 all the way

 

If you are aiming at making the 450-500rwhp horsepower, and IMO keep it as safe as possible, run the .82. Makes reaching the top end easier.

 

.82 a/r all the way. The .63 is too much of a restriction reaching 450whp-500whp. It might do it but at the expense of more boost because of backpressure.
