Twin gt37's or single ?
 

Ive got 2 gt37's right now. Been contemplating on doing a TT setup using both, but here lately ive been thinking about doing just one single gt37.

As for the motor right now, its just a cam only ls1. But when the turbos go on, its gonna get a set of P&P 317 heads. Was wondering, should i stick to my original idea, or would 1 be sufficient enough to make some decent power(Being over 600hp)

If i did the Twins though, its gonna be either a 370, or a 408.

i would do twins, that way when you get the new motor you do not have to re do everything

See i want to, but it seems like more trouble, and id like to retain my a/c if possible.

u can retain a/c with twins, just takes alot of planning/fabbing & a lil patience!!!
