I cant believe you're pushign 17psi on a car without a build engine. I mean e85 certainly helps but man thats a lot on a stock block. Also what are you using for engine management?
Yep it’s a bit for high compression. Detonation is the true killer, the e85 is what makes this level of boost safe/possible. It’s all standalone megasquirt, which is the other reason I can make this happen.
What I find interesting is I mostly compete/compare with buggies/builds that use motorcycle engines. Even like these sierra cars with boosted Hayabusa engines. They make huge HP but non of them make great torque like this setup. This is a perfect setup for a mirage or other tiny cars that benefit from the broad torque
