Jason getting snippy in the evil forum, same thread. But don't go there.

Jason who? The rx7club owner or is "Jason" some kind of "tuner" now. The guy has terrible customer service...I'm not even going to think about his rotary ignition knowledge.

Bridge port, 19psi, 19 degrees, no split. This motor ran for over a year and then was taken apart for refresh. This was done with SDS and an Electomotive hpv-1.

I personally like around 16 degrees at 15psi tapering up to 18 degrees after peak torque. This on a power fc with 4 degrees of split.

Is this timing on fuel alone, or with water injection as well?

No water injection and only 96 octane pump gas.

I have ran up to 20 PSI on 92 without water injection and 16 degrees at peak torque. I ran all Summer at 18 PSI. My AFR`s are very rich and probably helps.

I run on 93 pump.

If anything you want to lower the timing in peak torque, this is where it is most dangerous, then gradually bring it back up to keep the power curves steady.
