Can E85 increase performance in N/A cars? I suppose it could be great for 98 (European octane numbers, 95 is regular) only cars.
Seems like it could make sense when regular is 50% more expensive.
Yes, E85 does make more power in NA cars depending on the size of the motor. I've seen LS7's from the C6 Z06 pick up 30-50 whp vs pump gas. E85 lets you run shitloads of timing so the car is wayyy more responsive and the torque curve goes up accordingly. I plan to run my Z06 on E85 in the next month or two once I acquire it. E85 is great stuff for high revving motors especially.
lol damn, it took me a while to locate the nearest 100 octane station in the area that's not shut down or stopped selling the stuff.
Interesting thing about GTR's is that the newer models are apparently extremely prone to go into limp mode even on 93 octane (least according to other owners). Apparently it's a mapping issue and it can be corrected with a new ECU mapping. Guess I have my local state/regulators to thank for the water downed fuel around here lol.
I'm still a total noob to this scene, but it's fascinating learning about this stuff. As such I'm still treading lightly before committing to any heavy modifications at the moment.
I'll have to look it up a bit more about E85 in a GTR, near as I can tell I'll need the proper mapping uploaded to the car and just make sure the fuel lines don't corrode. Without the ECU mapping done it's apparently not as explosive as it should be running on E85.
That being said, I think there is an E85 station in my area, and it's still a ways out. Will have to make sure they're still around before doing a tune for E85.
There's a full aftermarket E85 kit out there I think, but it's way out of my expertise to install/do something like that myself, so I'll probably have to find a local shop that can handle it if I got that route.
Think I'm totally the wrong kind of driver for this car though - I actually like the stock look of the car. Some of the shops I took it to looked at me as if I'm some kind of weirdo for not ripping out all the stock parts and immediately bolting on aftermarket bits.
Some parts like the extended lips look really weird and out of place without having other bits replaced as well. Given my clear bra install didn't go quite as planned, I'm a bit reluctant to go to a shop to have the spoiler and the skits replaced.
Though there are apparently near OEM apperance dry carbon lips with brake ducts that are considerably more subtle, and it's apparently a fairly easy part to install as it's just a straight replacement.
For E85 all you really need is fuel pumps, injectors, and a tune. You can also have a 91 map so you can switch back and forth at will in case you can't get E85 when you're running low on fuel.
