    I have a 2.8 KB LC going on my car and I think it might be running on borrowed time. The car is currently tuned on 93 but I will be going to E85 with more boost eventually. I want the 298ci Livernois motor would E85 be enough to get the 9.7:1 comp shortblock? Also do I need to change the jet ratio for E85/spray or is it the same as 93?

    yea, you need a bigger fuel jet. just call the nitrous company that you have and they can tell you.

    You can easily go 9.7:1. E85 will handle it.

    Yes, you need to put a bigger fuel jet if you are running nitrous.

    thanks what is the highest you could theoretically go? My buddy had 10.X in his E85 evo.

    It would depend on how much boost you would run.

    so with 9.7 and a 2.8 KB at roughly 24-26psi I should be fine?
