I was just curious what everyone has there total ignition timing set at when running a power adder. I am running a 125 shot on 91 octane fuel with 16* total timing. I am thinking about experimenting with the timing a little with some 104 octane gas.

So, what is everyone else running for timing?

I'm running 11* total timing on 93 and 8psi, and 17.5* on 110. I've got the added compression of the pi swap so, thats not a good comparison, but you're probably pretty close to where it needs to be on 91.

150 shot, 21* on Shell 93

That seems like a pretty aggressive tune for a 150 shot. I'm assuming your running a pretty rich a/f ratio with that much timing. I was thinking about running mine up to 18* with some 91/104 octane mix. Not sure how much there is to gain with 2 more degrees of timing in it.
