You wanna be careful around your peak TQ, too much timing there is death .

I don`t have my laptop handy but this is what I started with . Usually I`m at 35 at WOT and 28-29 peak TQ (4000rpm)
If I`m running 5 blade props that have a ton of cup and load the engine I have button that drops timing across the board a few degrees.

What's your WOT boost PSI? Your blower looks like it can crank out about whatever you wanted!

About 8 psi is all I`m comfortable with.
With the 10-71`s that was 4% overdriven so it had a lot more in it for sure

Good call with the button. Would make good sense especially when laboring under tucked in conditions.

IMO, you should easily be able to run 34* at WOT with that combo, but like was posted, bring the curve in gradually with full advance at around 4800-5000 rpms

Damn that is some great information that for the great input.

Now do share what or powering. Sounds like it will be a blast!

You need to expand you OSO horizon and get out of the tech section once in a while! lol
A lot of great updates going on in sub forums.

Are you having issues keeping those Gaffrig mufflers clean and not tarnishing? I have had a he!! of a time. I'm sending them out to be professionally polished and then going to try a high temp ceramic coating.
