Great! You cannot get 115/145 anymore but you can sure get 100LL avgas (2ml TEL/gal)....just tell them it's for your "homebuilt" airplane!!



Have you considered (Mummerts) aluminum heads for additional detonation protection?

what size pump?

Rick, I ran E-85 which is acutally E-70 this time of year, with a knock sensor with absolutely no sign of detonation.. The big cam bleeds a lot of compression down low. I think this combination would run on about 100 octane easily maybe 93 with backed off timing

Jepito, Your setup is so much prettier than mine. I found that 7AS nozzles and an 80 pill worked best for me.

VERY COOL!



11.5:1 compression ratio is pretty high.



You probably will be limited to E-85 or propane! It would probably even detonate on 115/145 AVGAS wouldn't it?





I just LOVED the sound of it running!!!













Cheers,





Rick

well crap, you beat me to it lol. What nozzles are you using? I was planning on running deflector tips. Since 1 runner goes left and 1 right, 1 sprays down the port and the other into the runner wall.

Very cool Royce. Lot bigger butterflies than the Hilborn Y setup?
