I am also curious what your ignition timing was set to, as I have never dyno'ed a rotary with that high of compression (I intend to run with 9.4:1 in the spring). Where you able to run more than 30 degrees?

If you have AFR, that would be cool too, but I don't expect you to divolge all your secrets. I am mostly trying to learn from others experience, so I can decide the direction of my own projects.

I will never be able to afford a project like this, so I can only live vicariously.

I am surprised by the torque, I would have expected at least 280 Wlb-ft from a P-port.

The power is awesome though!

good work - keep it up.

I will have a build thread that will show every part of the car including the manifold. Timing up at 10k was 30 degrees. Pre ignition occurred at 32. Afr's varied but 12.9's are average. The torque is excellent. This is not a full p-port so its not going to quite match that. But the BEST of the BEST full p-port 20b's are making 305 FLYWHEEL torque. That is 260rwtq. I am only 19ft lbs away, and I think 10-15 more is possible.

I agree that more gains in torque is just a matter of tweaking and tuning!
The torque curve is really good for not a full-on PP.

Exactly. Now the real challenge and fun begins!
