[QUOTE="Mach828, post: 15451846, member: 102965"] Engine was still running strong with zero issues on the e85. I just pulled the engine out last weekend for a full tear down and rebuild. Forged internals, fresh heads, comp cams, etc. Also swapping in a built 4r70w with the engine swap. I'm going to see what it traps with that setup, no pulley change. I'm hoping for really low 11s at 125mph. Afterwards I will spin the blower harder with an overdrive lower. If I don't hit mid 10s at 130+mph I'll swap it out for a Paxton 2200 or if I'm close maybe just an SI upgrade. I think the detonation resistance that e85 provides really helps keep the stock engine running when you are pushing it to its upper limits. I wouldn't be able to reach my power goals on pump gas. With a turbo or big blower car you can just turn up the boost to increase cylinder pressure and power, with a little centri I don't have that option. One thing I did learn is that e85 on my car did not like low timing and a more conservative AFR 11.0-11.4. It would run sloppy and miss. It runs very smooth and more powerful with aggressive timing and AFR 11.8-12.0. Runs better off boost with the e85 as well. I e85 convert almost every car I own, its the best. [/QUOTE]
