Quick question @kingLT1 I had a ss 1le with a lt4 blower, injectors, pump, headers CAI running 10 psi and ran e60 with no issues on the low ,high or ms it ran strong. That got totaled. Ready to mod my stock zl1 1le I’ve had for 3 years now. There’s a lot of new parts that weren’t available before. Can’t seem to find an answer if I do headers, CAI, FIC +30, LPE HPFP, JMS booster everything else stock will I be able to run full e85? I rather not test it all and find out shits pricey. If I can run full e85 and want to do a pulley change what psi can I run safe without it starving for fuel. I remember this was an issue before If I added 2-3 psi I had to drop the e or my high side would fall slightly under 2000 and my injectors would shoot to to around 7-8ms. For the $ would adding a 2650 be about the same hp increase?

At stock boost you should be able to run full E.

On a 2.3 pulley, E70

2.175 pulley, E60


My brother is running FIC +30, LPE DI pump, JMS booster, Kong port, 2.175 pulley, 103tb, CAI, and Headers on his Zl1.

It is holding strong @ e62. It made like 660/660 SAE on a Mustang dyno that reads about 5-6% lower then a Dyno jet. Pull was made in 6th gear on Toyo R888's.


I don't think you gain much from a 2650 on 93 vs Stock supercharger with fuel system on E. Probably pretty close because the Ethanol will allow higher MAT's without needing to pull timing. So this kind of washes out the hotter temps produced from the stock supercharger.
