I will have this exact answer in a couple months but my plan is E70 on opels and lobe but as I said I'm a cheater and basically have a 5th too. I have some more info but am not sharing since to get the amount of E we had to run leaner whichbin ny opinion isn't the proper solution

KMO43

There is no price point on these new injectors as far as I know

When I do decide to run E-85 I don't really wanna mess with the 5th injector set up. My goal is to eventually run one of the ZFRs, and E-85. I don't think I'd get bored at 450-500, which I think would be done pretty easy on the ZFR with E-85

KMO43

Well I will have all this info really soon so you will know exactly where you stand

Multiple nozzles certainly make it more difficult and add the flow out of the nozzle due to the high pressure it's not on off directly, its more of a sine wave.

I was addressing it solely from a nozzle size change. Bernoulli's is a good one to illustrate that. I always forget the individual theories (I go to referencing pressure flow curves the manufacture supplies vs trying to calc out my own)

Honestly you won't get a serious amount of additional timing (normally 0* extra) for running E-85 over E-47, now you might get some more cooling due to heats of vaporization and lower combustion temperature. I haven't had the chance to compare EGTs of E47 and E85, maybe one day I'll get a chance to and see if there is added benifet of straight E85 over E47.

I can say on E47 you can add a crap ton of timing in the mid range and I'm damn near the same mpg as I was on pump (and I'm even blending E85 and regular)

KMO43

There is gonna be a point where running the higher % of E will get you more timing. I am not saying many people are going to see these benefits because the majority of people will be more than happy with a 450 wheel car. I will be looking into the limits of each fuel myself at a high power level because I can not buy E85 at the pump. I will be tuning on E30 to E47 and my dyno will prob be around E70 and as always I will share my info and do the best to help others out to hit their goals without spending more cash then is needed

Yes it can. I'm on stock injectors with only a bigger fuel lobe and I can run full E85 on stock turbo.

You just need to bump up your fuel rail pressure a little bit. It will also take awhile to tune cause you have to bump it up slowly. I started having fuel pressure problems at 5600 rpm and i'm at a limit right now of 6500.

It takes awhile cause your tuner has to do some math with the injector constant and your fuel rail pressure.



If we could. Why not just make a better fuel rail, lines, and hpfp to handle higher PSI? using a 5th injector kinda takes out the point of DI with timing advance and uses alot of fuel.

KMO43

So much wrong here. Why do you have to slowly bump the fuel pressure? I have yet to see any proof from you that you can hold optimum fuel pressure with inly the lobe on stock turbo. I bet ur IDC are super high and you drop FP like crazy on spool. The only place where you will be ok actually will be in the higher revs when the HPFP is more efficient. And the math on the constant shouldn't take very long to do if you know what you are doing

Sl0wbaltSS

I never get any codes for fuel rail pressure. I only get them when I'm above 5500 and not at wot.


My fuel rail pressure always sits at 2400-2480 during wot. My injectors are at 98% usually.

KMO43

Oh god!! You wanna watch injector time and have it at max 8ms or around 30% i bet you I rum more rail pressure than you and have never had a code pop up. You wanna watch pressure on spool not top of the gear.

It is possible to run full E in your situation but I you'd have to run it leaner and have a huge boost ramp to keep IDC down. So having to do this would make it slower than an E47 tune

Leave the poor guy alone would u? He's notorious for blowing up motors and wrecking balts. Incase u don't know, he thinks it's a Honda motor with "because eco-tak just kicked in yo". I know u care a lot about balts but u can't save every single one of them. At least not the JDM version ones that can rev to 9k that's only made for special people. Idk y ur taking this ricer so seriously. He's not getting any codes so everything must be fine! That's the very definition of logic right there... (in the ricer handbook of JDM cars)

Sl0wbaltSS

Yeah, i'm always near 6.5ms above 6k everyone once and awhile i'll get a misfire cause it goes over 7ms

Whats a safe Fuel rail pressure to bump it up higher to? 2500? 2600? I've heard it makes heat above 2800.


Also does having a higher fuel rail pressure with opels which [I might get soon] does anything to make more power? Less MS less time the fuel is in there and less time for knock = more timing advance? Did I do it right? Lol

KMO43

You keep on taking about furl at 6k which is not ur problem look at it on spool. Depending on the setup I'll run between 17 and 18 mpa. Well I'd need to see a log but if I am correct yes you'll make more power with the Opels. You wanna have the proper pressure for a DI car to make the most efficient power. Read the ZZP cam lobe article

I don't have an aeroforce or an hpt box or a fancy scanner tool so i'll have to figure out some way to see it.

But will is produce more power? I'd love to rent a dyno for a day and be able to look at mbt

KMO43

On a big hp car i believe so. Look at Taylor he made 650hp on a 62lbs/min turbo. The more air you have the better fuel you require

Oh lol well they are. Lol can get opels, which come with rail, for cheaper than 4 stock injectors

So you have no way to monitor your own ****, but you argue with a guru?
I see...

I know there is more, I just don't need wanna spend the money to get it. Maybe eventually but not any time soon. Yes we are cheaters lol is there many others running meth?

My tune literally scares the crap out of me right now, I gotta tweak it, as soon as it it like 5k rpm and it goes to full boost and 17 timing my car wants to torque steer me all over the road and murder me. The peak power hits to quickly all at once. Like a fricken nos hit lol. I'm gonna smooth that out some more. Fricken car lol

KMO43

No not too many running meth usually its 91 **** or e47 my meth will basically be the same as having a 80lbs 5th

Oh I know but I answered questions that others can hopefully help others out

Do you have Powell cabs or his trans mounts? Makes a big difference.

tomj77

iTrader: (2)

I'm running 91 ****. lol but that's why I run meth. but u know that

tomj77

iTrader: (2)

I just have the trans mounts. it literally didn't do this until I uped the timing and adjusted some stuff. I guess the winter tires don't help either, or winter for that matter, I do spine till 160 at full boost so I guess that's why. lol

Spin till 160? Sounds wicked.
