Unable to reach Zack. Wondering what curves people are running for 50/50 domes and for full race domes. Running wet pipe. Currently am at 32 deg max advance on pump gas.

This is race gas.

Does anyone have a curve for 50/50 or avgas?
It’s going to be pretty much the same. You could experiment with a little more max timing but it’s generally always 32 max til 5k or 5500 then taper to 19ish at 7k. That’s the same curve for a LOT of motors. More related to the pipe vs the motor from what I hear.

Am I chasing little to no gains by trying to squeeze out another degree or two or is the increased compression where I'm mostly going to find my power increase? Current timing is 32 max.

Maybe try burning methanol with as much nitromethane as you can afford?
