E-85 on a stock 370z?

JeffP-Z

Stupidity in reality....but I was looking to take advantage of the marginal HP gain I would have expected. But as I may have already said, I leaped before I looked...bad plan! I was getting beat out there by guys with much better builds and thought it was a quick easy way to make more HP. I am too impulsive sometimes and it got the better of me this time. Add this to experience category and keep on keeping on. Fortunately I am a persistent SOB and wont quit till I get this right. I am on a mission to learn as much as I can now and will try to STFU and read more and understand better.

It's only worth ~10whp NA. I see you've mentioned going TT since I answered and it's worth way more power there, or at least allows for more w/ a comparable safety margin. I'm not sure what you should expect to pick up boosted on E85 over 93 or 91, but Spooler or Hotrodz might could share some experience.

If he's going to run 91 and e85, he'll pick up a lot more hp on e85. He'll be able to run a lot more boost on e85. With my supercharger, I get knock above 13psi on 91 and I can run 17psi on e85 with no knock and could go higher. My 91 hp number is 480, my e85 number 680. 91 octane sucks!
