I like the idea. i know a guy here who can tune up to run E85 . Does anybody recommend changing hoses fuel hoses etc? Or anything else? Let alone can the VG30 burn comfortably on e85? Im interested in any suggestions. Its 1994 NA aus spec low kms
I have not tuned an NA on E85 yet but I expect the gains to be significant. Throwing in an extra 5+ degrees advance on any engine will net you a substantial increase. I'm doing a NIStune install for a customer at the moment with the newly released feature pack which turns your stock ECU into a Flex Fuel System so no matter if you run E85, ULP or a mixture of both, NIStune will adjust for it.
At my old work we did an E85 conversion on an NA BRZ. Gained 25 KW ATW from the fuel alone, having already been fitted + tuned with the best bolt ons available. Would love to see what a Z32 would do.
Even so it's a lot of $$ for not much go fast. I get that timing will do good things if you're interested in pushing the limits of an NA but it won't be even a bog stock TT
If the dollar$ are spent there's no reason why a normally aspirated engine would not achieve big horsepower.
Na power will always be more expensive than adding boost though, if you have a healthy NA you can add 10psi for about $5k which will put you over 200rwkw, the same gain keeping it NA is going to need a bunch more clever engineering. Nothing wrong with doing it just don't expect the same bang for buck. An NA on E85 will probably feel nice and zippy though, should add a bunch of torque down low at high load.
Can reach mbt on an NA with just 100ron e10......ive added much more than 5 degrées before. You will need to change your injectors, mine were at 92% with a 12.6:1 afr on 100ron.
