E85 is definitely making an big run into the powerboat market. And why wouldn't it? It's benefits and potential outweigh the cons no question. A real slick deal is EFI flex fuel. Can run any percentage of E content and the tune adjusts on the fly via sensor on the fuel line. I converted my car to this. Injector Dynamics 1300's are specifically designed for Ethanol tolerance. Personally with 572 blown on E85 my goal would be higher than 800 as NA 572 can get close to that goal especially on E85 while keeping things simple. Either way sounds interesting and happy to see more E85 users...

I did the same test as well but for almost two years with no ill effects either. Guys in the street seen have been running e85 and turbos for years with huge success. I can't believe it hasn't caught on in our hobby. Imagine 11.1 static compression and still being able to push 15-20 pounds of boost (that is a conservative number), all on pump fuel that is around a $1.25 a gallon at the moment. This is all done with the same tanks, pumps, and parts we use in the offshore world. As far as the "water" being such a huge problem, it's really not. Water is attracted no more to e85 than it is e10. And if your that worried about it you can put a ball valve on your tank vent lines and close them when the boat is not in use.

I don't know about an N/A motor but my brother's ProCharged motor had the exhaust seats beat up a little after 3 years. The .780 solid roller and 725lb springs may have contributed.

the e85 you get from the local gas station might be e85 today and e72 next week.it is all over the place.the only way to get true e85 is to buy in race fuel quality,and that,s not 1.25 a gal.that being said you could buy 55 gal drums of race quality e85 and still be less money than filling up with 87 oct on the water.

Not that I'm aware of. It is truth Ethanol's lubricity is not equal to petrol. But as to what extent it has a negative affect on seats isn't very clear as far as I'm aware. I know many people running E98 without issue in automotive. Most users burn pump blends which end up around e60-e70. Personally I don't see a reason for anything above E70 as most the gains are experienced by E60. There are still smaller gains to be made but why tax the fuel system for gains that could be obtained otherwise utilizing the E60 benefit? 2 fold you gain more corrosion protection and lube qualities if such benefits are had, which they very well likely are vs true E85.

The varying E blends are what make flex so nice. I have a digital readout telling me what the ECU is reading and tuning for. My local pumps actually vary only slightly. E60-E65 year round. Other places will be different which again is why flex is cool. Can even run e0 or e10. Just automatically lowers tune.

Been watching my buddy race his E85 burning, twin turbo, 2200 hp Nova Wagon running all year on essentislly a shelf part 540" and placing 2nd in his class @ drag week. It certainly has my attention!
