Tuned my new setup S366 full race mani E85 - Chime in!
So I finally tuned the new setup on E85 with the fully built motor, S366, full race manifold. I'm happy with the power but something wasn't right. Granted it was hot in the Dyno bay, and the motor was super heat soaked, it was still way lower than I expected.
665whp / 429 tq @ 30 psi
3" dp to 3" exhaust
9.6:1 CR
Stock IM
Stock ported head and cams
S366 .91 twin scroll
I threw more boost at it but didn't gain 1 hp. This motor has always been known to flow like crazy and back pressure may be an issue here I don't know without testing. The 6266 I had made way more power sooner (500-600rpms) everywhere in the powerband.
The 6266 with stock motor made 685whp/495tq @26 psi.
The chart from today at 30psi.

Any engine bay pics? What size t4 twin scroll hot side are u running? Something is not right here. This turbo should max out at a much higher hp level. I'm guessing you need a 1.10 ar t4 divided hotside. This is a 2.2l engine? Dyno chart also looks really laggy to me for a 600hp twinscroll setup.

I beleive it was JEff Evans that did testing on the twin scroll setups, and how he was having back kpressure issues, until he want crazy large.
Check out his site/blog for more info.
.91 is super small on a twin scroll mani/turbo.
