.63 vs .85 housing rwhp?

[434nova]

What is the most you can make on a .63 housing? Is 700 rwhp possible? At what point does one consider a .85 housing? I am looking for 9 second ets and was looking into a 6766 or even a 6466 just curious on what housing to choose.

It really depends on your combo , but for 9 sec power I would definitely go with the .85 housing . I would even swap to a 4 bolt if you had that option . The back pressure with the 3 bolt turbos are really high

imo, anything over 400whp I'd switch out of the .63 just to be safe.

But in Buick land, physics don't apply.

Surprised know one hasn't made 700hp with 44/49 w .63 in Buick land .... with someone fudging the numbers behind the dynojet. lmfaoooooo

I run xxx with a tiny turbo and housing but im NOT gonna tell you my car is 1000# lighter than stock.hahhaha

137 mph in a full weight car is when I would switch to a .85.

Oh in Buick land, PTE lists there .78 as a .63

So in reality, NOT Buick land, the pte .63 is would be like splitting hairs against a TRUE .82... like Tnetics .82
