I have the PFAb twinscroll with a GTX3582R w divided 1.06 A/R housing. Should be getting a dyno soon using 93 octane, 93 + meth and then MS109. I'll post up the dyno graphs when its done, but Jay at Real Street seems to think it should make decent power. We will see, as it hasn't been tuned yet, but I'll add my $0.02 when I have a graph to post.

I think the moral of the story is don't do a divided t3 hot side and expect Holy Shit top end.

so the best is if u need a bit of fastspool and big power u should go divided twin t4 flanged and a big ass turbo like grx3583r + ?

I've actually got that setup and tuned it on 91 octane. We got 550whp at 21spi with stock AP1 cams. Then we changed to Brian Crower statge 2 turbo cams and got 600whp at 21psi.

This was almost 2 years ago. Now i'm switching to a sidewinder setup with a Precision 6466 bb turbo. I've had too much hassle with the 2 wastegates, water lines etc.. Back to just 1 wastegate and oil cooled.
In the end a relatively simple setup is better.
