Can someone help me by giving me a basic idea of safe Timing values for a rotary i know you want to keep the AFRs around 11:1 but would going up to about 11.8:1 be to lean?

Where are you located?

11:8:1 is a little on the lean side, 11:5:1 is about as high as I would want to take it. 12:1 would be considered dangerous, 11:1 safe, 10:1 a little rich. Timing starting at 0 psi could be around 30-35 degrees then taper down to 15 degrees by 15psi. My timing is set at 36degrees before 0 psi, then 31 degrees at 0psi, then tapers down to 14degrees just after the 15psi mark and holds steady 14degrees the rest of the map. I tuned the car for 11:1 on the dyno last time I went and with these timing values its stayed together running 18psi for a couple years now, so in my mind its pretty safe.

I live in baltimore MD thanks for the info 94 touring if i have any more tuning questions do you mind if i PM you? or do you have aim?

If you were close to me, I'd offer to tune it at our shop.

Are you referring to gotham Racing? one day i might take a road trip down there how much do you guys charge?

Can you offer any hits /tips on tuning? BTW I really wanted to learn how to tune just to know ya know? its one of those things i relaly want to know how to do

Shoot me a PM anytime you feel, or i'm on aim all the time as touring94.

Yes, Gotham Racing. We charge $350 for tuning. If we do a motor rebuild it includes free tuning.

have you guys played with the timing split much?
