Balancing gas mileage and power with boost, 93+alky, and **compression ratio**
I talked with my builder and he said alcohol and gas is a nasty mixture - won't burn well in high ratios like that. Looks like I'm stuck with 93pump in the main rails and unleaded race gas in the second fuel system, plus maybe a "regular" style alcohol setup with the primary benefit being extra...- 280Z28

Balancing gas mileage and power with boost, 93+alky, and **compression ratio**
The alcohol would only come into the picture under boost, and as such wouldn't affect my gas mileage under normal driving. I plan to use 42lb injectors on the 93pump rails, and another set of 42lb injectors on the alcohol rails. I take it I can build the second set of rails to handle methanol...- 280Z28

IIRC, methanol would likely be too damaging for me to want to use it with all the electronics involved. Water doesn't burn (durrrr). Leaded race gas definitely kills O2 sensors. Which leaves ethanol. I'd be running 100% (in this case) ethanol in the 2nd fuel system. Say I went with the high...- 280Z28

I highlighted compression ratio because that's the item I'm most up in the air about right now. I'm working on a new build with some peculiar goals that I think are interesting... a step beyond the thinking that goes into most race motors. Design restriction: When *not* under boost, the motor...- 280Z28
