370Z's and E85?

dirTy_shoeZ

It's actually n/a. And I've seen really nice gains on all motor cars actually, so guess we will see .

MightyBobo

Examples? And define, "nice gains". 5-10 HP at most really isnt much of a nice gain for all the hassle you need to put up with (for example, replacing your entire fuel system really, tuning, and finding a reliable source of E85 that doesnt go to E70 or so during the winter time...)

Your money is better spent elsewhere, almost guaranteed.

I've seen anything from 12-20 whp gains, and I live by a pump that's e85 year round, not to mention I work at a shop so the cost was actually quite worth what others would spend even to see 5-10, so even if it's 5-10 in my case its quite alright.

MightyBobo

I dont even want to think what the cost in parts alone would be for everything to pick up only that much horsepower. Injectors, fuel pump, maybe some lines and fittings, a tune...at least $1500-2000 for a tiny bump in power.

But hey, in for the dyno charts. Before and after, please.

Not that I would waste any time converting to E85 on a NA 370z... but as a heads up, nothing in the fuel system needs to be replaced for compatibility.

The 370z fuel system is E85 compatible. I have had not a drop of anything but E85 in my daily driven Z for the last 15,500 miles now.

All it will really need is injectors and a tune. Maybe a pump but I bet the pump will keep up.

I have an E85 station 3 minutes from my driveway. Its still a pain in the ***, because my car is married to that station. There are very few stations that actually carry it, even though the websites that show you all the E85 stations say there are 20x more... none of them actually carry it any longer.

I only deal with it to increase my odds of keeping these junk VQ connecting rods in 1 piece with boost.

Thanks for the insight on the fuel system, Phunk - I was going off of assumptions as far as the fuel pump, but if you're running it now, cool.

Thanks for also reinforcing my feelings that an N/A E85 370 is silly :-p

Thank you phunk, e85 also runs a whole lot cleaner in your car, and yes the avg person would just need a walbro 255 and a injector that will handle the power whatever ur wanting to do. My system is bigger than what I need but I hope to supercharge it when im done seeing what the car does with this and seeing how it feels, But for now the car will be tuned on id1000's and a walbro 400 with long tubes,gen 3 intakes, amuse y pipe and exhaust. So we will just wait and see. As for the people that insist in complaining about price and gains. It didn't cost me what it may cost the avg person but even if it did I would say for the price and gains I think u may receive it would be much different than buying intakes and test pipes price or gains whys and every extra bit helps. As for me I'm wanting a certain amount of power but most importantly I'm chasing down decent numbers and a very nice powerband.

Well... I cannot say for sure if the factory fuel pump will be able to keep up in volume with E85, but I predict that it will. I am personally running an Aeromotive 340lph fuel pump upgrade inside the stock fuel pump housing... my car is twin turbo and there was no chance the stock pump was going to keep up, especially with E85.

But based on some hear-say I have come across with people who have tested the limits of the stock fuel pump in higher HP scenarios, I think there is a good chance it will be able to keep up with a NA E85 car.

I am using the ID1000s and the Aeromotive 340 for my setup... it kept up pressure no problem at 524rwhp at 7.5psi I think it was... I ended up turning the car up to 9.5-10psi after the dyno... I cannot tell for certain if I am loosing any pressure on top because my only fuel pressure gauge is one of those mini ones in the engine bay... but I am not seeing any leaning out in my wideband or having to majorly jump up the injector duty cycle.

Those injectors and that pump will not have any issues what so ever making anything I'd say comfortably up to or around 700 whp. We run the id1000s on a customer evo here and it made 614 on e85.

dirTy_shoeZ

I'm on the dyno right now before was amuse r1 straight pipe and k&n drop ins making 293whp and 241tq as of right now with stillen intakes and amuse y pipe on e85 with stock cats until the long tubes get here next week and it's 327whp and 263 tq

would it be worth it for me to convert to e85 if i only have gen 3 cai and test pipes? and if it is would thses injectors be a good choice? and would that be the only thing i have to change, the injectors?

Unless E85 is SIGNIFICANTLY cheaper, you have an excellent source that doesnt change composition, or and you are staying N/A? No.

If you absolutely must be unique? Sure

If you are running forced induction? Definitely.

not worth it for you. 1000cc would be too big for NA and E85 too
