With the only caveat that you must run E60 all the time and fuel mileage will drop by 25% or so. Otherwise, if the OP isn't bothered by those factors, I agree with you, its hard to beat for the money.

Maybe I'm misunderstanding, but one could run any pump 93 through E' with proper flex' tuning, yes? You can't get all of the gains of E' unless you run enough, but you can install the sensor, adjust the EQ/AFR for E', and just drive any E' content you want, yes? I'm probably overthinking, ha...

You are correct, but in order to benefit from the performance that E60 brings, you must run it all the time. Once you put anything less than that, performance starts to drop accordingly with the ethanol content. I was addressing King's post that it will run and better and more consistent than a bolt on and pulley 93 octane car. What he said is possible under the right circumstances....extreme heat soak, but it also means that to see that happen would require E60 all the time. I love ethanol but there are some downsides which weren't mentioned.

The performance drop isn't much as long as it's E40+. So the E content doesn't have to be dead on E60 all the time. E40 is still 100+ octane...I have seen NA SS cars gain +26whp on E46 then only pick up a few HP on E60. FI cars gain double the power vs NA on E. So worse case the car might be down 10whp on E40 opposed to E60. E60 is usually a 50-60whp gain, doesn't cause heat soak vs over spinning a small supercharger.


The fuel mileage hit is offset by lower cost... it's still cheaper to run.

It's easy to mix and there is no reason not to run it.

This is true but you're still talking about 630-640whp, where as you can take a bolt-on pulley car to 700whp on 93 octane. Performance may fall of SOME under extreme conditions but otherwise its still more power and you won't have to look for E85 stations. Again, I won't argue that going the E60 route and flex tune is the best bang for the buck though if you can live with ethanol's minor drawbacks.

Yes. It’s a 2011 SS with a 427 Dart block LS with a 102mm Garret turbo on methanol “street car”. Still has glass, power seats, radio, etc but with a 7.50 cert cage

Man, this is awesome Any videos of passes at a dragstrip?

Location California, does that mean 'premium' gas is that crap 91 where you are? Can you get E85 in your area?

I agree with KingLT1, E40-50-60 flex tune would help a lot and it would not have heat issues like pulleying will. Plus if 91 is what you have for gas, you are already giving up power even stock, and with a faster-spinning blower it would be even worse, higher IATs and probably lots of KR spoiling the party IMO.

Haven’t made any passes in her yet. Going to be a lot of work with the traction control as she is a heavy girl. Trying to get into the 7.90s but not sure I can with the car weighing so much. I can’t seem to figure out how to post pictures right now, but I’ll mess around with this latter and see if I can get some up.

Correct with our “premium” 91 octane. I can supplement with some Boostane. We have E85 out the pump down the street from my house. As usual, sounds like a simple tune is going to turn into injectors, fuel pump, pulley, etc. Think I’ll leave my ZLE stock for now. Need to finish my 5th gen first. Can only have so many projects at once
