i find it hard to believe you can run much higher than that with any 60:1 turbo unless you are running some insane boost levels, hell 20PSI is pretty damn high regardless of what supporting mods you have on a rotary, thats like pushing 30PSI on a piston engine.

For example one of my customers was making 406rwhp @ 15psi on a T60 with a very mild tune from Steve. That is on an s4 engine. If things goto plan and I end up flying out there and doing some tuning on his new setup, I'm more than sure we can muster atleast 430rwhp at the same boost levels. I too have seen much higher numbers, however I don't have any dyno sheets...
Here is that guys car: https://www.rx7club.com/showthread.p...3&page=2&pp=15

Here are several examples pulled from Dave's site:
http://www.speedmachineperformance.c...ts.asp?Cat=144
At the bottom there is a ported fd engine with a to4R making 485rwhp @ 15psi. Chances are @ 20psi its going to be atleast 535rwhp. Moving to a ported fd engine with a 6.7mm larger inducer is not going to yield 135+rwhp over an unported s4 engine on a 60mm comp.....
And yes Dave has mustang dynos to back it up.

Thats great, I know who dave and Speed Machine are, I talked to him on the phone two days ago. So, where are YOUR dynos? I am growing tired of you constantly running your mouth with nothing to back it up with.
