Default 370Z's and E85?

Coming from the EVO world where E85 fuel is becoming the NORM. has anyone been running E85 with the VQ37's? Is it something that is possible right now? Are the people able to Flash a ECU for E85 yet?

Also.. what do you think is possible with E85 and a bolt on turbo kit on stock block.. 550-600whp?

Instruction manual explicitly states NOT to use E85.

Well, you CAN'T use E85 if your car's fuel system is not designed for it, even if there are ECU flashes out.

More than likely, yes. Would need a custom tune preferably since you burn about 30-40% more fuel using E85 I believe, for the same performance.

In addition to the upgraded fuel system to resist the corrosive nature of E85.

a side affect of using E85 could be a slightly lower oil temp do to the fact the combustion is cooler. maybe?

As Liquid said, E85 is corrosive. If you use it in a system not designed for it it will eat through seals, and just about anything else not designed to handle it. BAD JUJU! I'm even worried about shops that sell a blend and aren't required to post signs or anything.

^^^ Yeah, I'm willing to pay a couple more cents to fill up at a 100% gas station.

We will need a tune and bigger injectors. Is there a ecu tuner out there that can modify the ecu tune?

I ran e85 on my sky redline and went from 290 whp 340 torque to 315 whp 390 torque and yes that is to the wheels on the Trifecta tunes respectively.

E85 will give a lot more power properly tuned. It like race fuel and it goes quick!

Corvettes just need a tune. Nothing else. Nada. Has anyone actually confirmed the 370z fuel system would not handle it?

What i figured. Plenty of stock fuel system e85 vettes out thee, and bigger pump and objectors as well. I don't think the 370z should be any different, except with vvl it should see serious gains.

There are some in-tank hoses in the EVO X that have proven to not hold up to E85.. the little white pressure lines inside the fuel pump assembly. The 370z has a couple similar hoses, but they are black and I am pretty sure they are either Nylon or Teflon, which would be fine. So far they are holding up. In the next month or two I will be inside my tank again so I will see if they are swelling up or not. If they are, they are no big deal as you can easily replace them with 5/16 in-tank hose if needed.
