so it is safe to say that 20whp is achievable?

What would be the proper injector size for running E85? Is 450cc enough? How about 550 or 600?

Yes, ECUTek.



ECUTek didn't release "flex fuel" per-say. Their software allows for custom maps to be written, and the tuner is able to use those custom maps to add Flex Fuel support into the ECU.
VV,

Great write up! Any chance you could publish a parts list to go E85?

Our Z is about to be Twin Turbo here in the next couple weeks, so the flex kit (if I have the time to put together one) I'm just going to integrate into the fuel line kit FT sells for their TT kit. When I pull the motor I can take a look at the fuel lines and give you guys the part #'s to buy to integrate the flex sensor to the stock fuel system.

If I don't forget... lol

I assume you will be running some kind of stand-alone engine management system to utilize the output of an ethanol-content sensor?

You also had a dry sump, jun cam, and retarded manifold and revved 8200 rpms. Most of us won't see those type of gains switching to e85.

Im still not convinced. 93 vs e85 with zero changes makes zero sense.
