NA 370z on e85
 

well i figured you guys would like to see, JMS racing out of san antonio put the Z on e85 with just stillen gen 3 intakes, amuse y-pipe, amuse r1 titan, and uprev with e85 (stock cats and stock headers)

we were having issues with the rpm reading to get an accurate tq curve but before the spike it would be around 264 ft lb's and made 323 whp.

next weekend we should be putting on the long tubes and we will go back and see what happens none the less the car feels geat but I am unaware of what other people see with these mods on 93 octane. please fill free to chime in.

DYNO VIDEO: click stupid picture lol

On a dynojet I would generally put that setup at around 300 whp, Pushing 323 is impressive with a fuel change. Surprising as I just did a tune and had to take out 3 degrees of timing with 91. Are you running stock injectors?

Thank you, I changed the fuel over to id1000's and changed the fuel pump to a 255, I had a 400 but it was to large for the tank for a simple drop in and would've needed an external regulater going that size.

When we tuned mine in the past it was on 93 and when Jorge tuned it he said it generally didn't like timing and would make more power when backing the timing back out after advancing it. But with the ethanol since it burns so much cooler was able to take more timing without breaking a sweat.

Any details on the process!

thats making me think about doing the switch !!

I cant wait to see the result with the long tube header !! (which one ? )

the 308whp STD on a dynojet is pretty much where it should with your current mods
a gain of 14-15 whp is quite nice to see ! :)

Good stuff Mike. I'm surprised to see the gains on E85, badass.

Just as reference, I only put down 300/256 on 93, same dyno. Jorge had the same issue and pulled back the timing a bit to make power.

In for updates with mods. Would deff do the change if it makes some decent power. Thant and E85 is a good dollar cheaper then Premium over here.

Great to see you guys are using E85

That is one of the reasons I just Joined this site , and to see if should try to teach those Mustangs a lesson , or just leave them alone , there are
several in my area ,,


I just purchased a 370Z Roadster , Manual 6 speed , I am 53 years old


I really think Ethanol cannot hurt my car , Just wondering if I can run it
without advancing the timing ? or doing anything ,,

Should I try one of those Chips ? thinking about installing those Stillen high
flow converters ,, just something simple that will not void the warantee yet
only 200 miles on the Black Roadster

So Just saying Hi ,, lots more to tell you about the Ethanol ,, just not sure
who is here yet ,,

Thanks
Fred

ok that was 2000 miles
 

thanks

:iagree:

Yeah, that's a nice gain. What was it SAE and what was the actual CF used for STD?

Can we run E85 with stock fuel pump and injectors?

Damn... now I want to retune for E85... although not even sure where to get it in FL...

Anything newer than a 2010 will need the full standard set of bolt ons. Those include full exhaust, headers / testpipes / HFC's, intakes, pulley (if you condone it), flywheel (might as well upgrade your clutch at that point), and a tune. Gears are an option as well. That would put you on par performance wise and should be running away from them, but the lightest mods on them will tip in their favor.

Back on topic, how much did the objectors and fuel pump run you?

The injectors will run anyone around 450-750 depending on what u want, I ran ID1000's and the pump is a standard 100 dollar walbro 225. It was nothing more than installing that and putting news new o-ring and hose, then of course u need a tune.

I'd say no to running ethanol on stock pump and injectors. I dont know about the pump itself but definitely not injectors

in for updates... e85 is local to me now

saw that on facebook, looks good..

Okay, that makes sense. I thought E85 was corrosive. I missed where you said that you had picked up new injectors and pump.

That's a very tempting modification.

any update with the long tube headers ?

Still waiting on them to get here :( Updates when they get here, they were getting coated Monday when I checked on em

Are there any cons for converting to e85 on a daily driver?

Also do you know what other 370z's with similar mods but running 93 octane made on that dyno for comparison?

Oh and 1 more dumb question....so you said all you changed on your car was the injectors and fuel pump and got a tune for e85. So if you had the uprev tune that let you change the maps using the cruise control, could you have an extra map for regular 93 gas in case you can't make it to an e85 station?

What I understood were I was about a 15-20 whp gains with switching and the car made nice tq also. The cons would be of your not close to any pumps otherwise it's cleaner cheaper and makes more power. I will say I lost mpg but If that's a concern then it's probably the wrong hobby.

And yes u can change ur map and put 93 aslong as u have a tune for it. But I personally don't like it just cause no matter how u look at it ur not putting 93 back in a bone dry tank with bone dry lines. It's just not my preference but to each is own. Another thing to look for is the o-rings expanding on ur injectors switching back and forth. With ID's I've never seen that problem but I have with rc and duetschwerks

good luck with the new parts bro :) more power

I'm definitely making the switch to E85 this fall. Really wish there was a tuner here in AR.

Hell this sounds like the way to go. All the pumps around here have the "At least 10% ethanol" on them and we just got our first e85 pump at the new Mapco that just went in. For me I guess I would need to wait until there are more e85 only pumps in town as it would be a PITA trying to make it to that specific one everytime...or go on a road trip.

Just wondering, the corn issues with the drought effecting prices at all?

Wow... pretty impressive .

This looks pretty kicka$$. Definetly contemplating...:driving:

In for results with the long tubes

any specific comments on your mpg specifically? I know you mentioned it went down, which is expected, since E85 requires more volume

Hey any updates on this? Its been awhile! :tup:

yeah updates with long tubes? and where are you getting e85 in san antonio? i don't think i have even seen a e85 pump around my area

Member, phunk, has a TT setup running E85. IIRC, he makes more power at lower boost with E85. His videos are sick! Just look at the tach go wild, and that's about 8 PSI. My engine response is nowhere near that with 91 octane and 8-9 PSI.

If E85 is more common in my area I wouldn't mind doing a conversion.

Here is a link to e85 stations nationwide: E85 Stations

Not sure how well it works, but give it a go.

Would these injectors work? 6 1000cc Injectors Nissan All 350Z 370Z G35 G37 GTR I35 M35 Skyline VR38DETT | eBay
And does anyone know if they are any good? And do you really need to upgrade your fuel pump? And I heard the gas lines can handle it, and sorry one more question, I got an 09 and I got gen 3 cai and test pipes, would it be worth it?

I think you absolutely need to replace the pump, lines, and injectors. E85 will corrode parts designed solely for gasoline.

Alright thanks, and does anyone know if the injectors I posted are any good?

I would not trust ebay on no name injectors.....The blood of your engine depends on it!

alright thanks, what injectors should i get?

Bump.

OP hows it going? I've seen DSM's and evos run e85 and it gets the black sludge. When you pull the pump and look at the sock it's solid black from e85 eating the lines. But we don't have a return fuel system so whatever eating is going on (if it happens) will just clog the injectors. But subis have no issues so their lines are clearly better. My tuner wants me to buy a pump and injectors and tune for free so he can see what e can do.

IPS???. If this and your intake system work combined shows good results I might have to come down there and visit IPS for the same treatment. :tup:

Hell yeah. Today was a open house. Good turn out. Check out IPS on facebook. Huge shop and some insane cars like their corvette that runs 6 seconds and 220+

Here's Stas the owners new vet getting tuned by Bill or Dillon. Not bad for just a tune.

From what I read, I do loose some mpg but u gain hp
