I'll throw my vote vans way... As it's 'local' compared to the islands...
I'm hoping to make it out this fall for a couple days... Enjoy the city and such... Maybe take a quick dip into the Seattle... See if their are any meets, on either side of the border.... J.

I believe the above, as I did 216 WHp (Mustang) with 8.2:1 polished s4 turbo rotors, stock s4 rotating assembly (not balanced), stock intake manifold and very mild porting. An equivalently built 20B should make 320ish WHp.

Nice work, can you link me to the dyno chart?

 I fixed the rich spot later, but I had the AFR trace off for the next run that I got a picture of. Although the curves do not line up, the rich spot made the dip in the torque curve. I wish I had a picture of the afr on a run with a 13.3 afr throughout, but once it was good, I was fooling with trailing split and had the afr trace turned off. Edit: I should also post here that target AFR was 13.3:1 (optimal power). Ignition timing was fixed at 38degrees BTDC above 3000 rpm. I was initially running from 3000 rpm, but I had to wait too long between runs for engine cooldown, so I started at 5000 instead to minimize the engine heating. I revved to 9,000 once (182 WHp at 9,0000 rpm) I think I was ignition limited, as my peak VE was reached at 7,700 rpm and my power had long since started to fall off at that point. BSFC was right around 0.42 lb/Hp.hr until 6,800 rpm, where it started to increase to 0.54 lb/Hp.hr at 9,000 rpm (which also indicates an ignition problem). Interestingly enough, this engine only barely eaked above 100% VE (I saw 102% at 7,700). Rotary engines have a lot of potential.
