I can get a good deal on a gt3561s, and from what I know if it (what I've been told/read) it should be good to about 600 wheel horse, get full boost about 5200 ish, and make 500 wheel horse on a 9.1 1.8L about 22psi.

If anyone can give any info I'd appreciate it. I'd like to make 500-550 wheel (mustang dyno) on 110 octane, it's gonna be mainly a street car, raced at the track about once a month thru the summer

 

I do

 

I am running a T4/T67 on a daily driven car. I love it. Made 424whp on only 15psi.

 

anyone else?
