Few questions E85
 

What injectors are you guys running and fuel pumps?

I am currently running the siemens 2200's but they are low impedence.... I have a injector driver but if buying new injectors it just seems smart to buy the ev14's...

I am going to run 6-8 injectors on the new set up. Thinking four to six 2200's and two 1000's .

What pump? Weldon?

Thanks,

Mike

Mike,
I will be running EV14's. A few FD owners down here are running them with no issues.
As far as pumps, it will be dual Bosch on a CJ hanger

I know of a few running the SX18203 fuel pump

Hope this helps

why not 8 2200? they idle just fine.

8x2200 is the way man

Thanks guys. You think I will need 8? That's a shit ton of fuel! So what pump you guys using?

We run a Mechanical Waterman pump with 8x2200cc Bosch. Idles beautifully. Do it now, before regretting it later. Rotaries are thirsty SOBs.

i will be running 2x1000 and 4x2000 with the xsessive LIM. Dual walbro 485 in tanks. its been awhile since i checked but i believe its enough fuel for 900hp @ 85% DC

I think you can get away with 6x2200's at your power level since 4x2200's will support around 600rwhp with high duty cycles. If you aim for north of 800, might be a good idea to go for 8x 2200's.

Probably need to go with a mechanical pump or dual/triple Bosch 044's. I've heard the dual Bosch pumps can handle 800rwhp on E85 but I don't have any proof. It would make sense since one can handle 400rwhp on E85. Mechanical would give you a lot more headroom.

Sounds like 8 2200's is they way to go then. Still up in the air on a pump. Anyone have opinions on a big aeromotive or other external pump?

Like this:

Aeromotive 11104 Aeromotive Eliminator Fuel Pump - Free Shipping on All Orders @ JEGS

Good for 800whp+. Proven as there is Multitude of people running 2 044's making decent numbers. I know of 2 people that has use the same 2 044's for 7+ yrs, going from Pump gas to c16 to q16 to e85 to e98. There's 101 ways to skin a cat. just my .02

Mine.

If it is a street car, 2 Bosch. If it is a race car only, go mechanical.

My feelings also but whats wrong with the eliminator?

The Aeromotive Eliminator can't flow what the dual Bosch pumps can and the Eliminator is not as reliable.

Bosch 044 for street/ mechanical or weldon for track.

walbro 400lph

For the power you'll be at, this is a great electric solution. Mechanical would probably be a better idea though.

Holley Performance Products Dominator™ In-Line Billet Fuel Pump (Hi-Flow); Up to 1800 Horsepower EFI; Up to 2100 Horsepower Carb 12-1800

https://www.holley.com/data/products...n-linePump.jpg

From the Holley site. What does pressures up to 80 psi mean?

"Need to feed some serious horsepower? Have a nitrous or forced induction powerplant that also sees street duty? Holley's new Dominator™ in–line fuel pumps are the answer! The patent pending twin pump design allows you to use one pump for cruising and both pumps when you activate the nitrous switch or start building boost! By staging the second pump, you eliminate the unnecessary recirculating and heating of extra fuel which can lead to poor performance and hot fuel issues. As an added benefit for the hard core enthusiasts that run events like Hot Rod Power Tour and the Baja 1000, the extra pump offers the peace of mind that you will always finish what you start! For hard core race vehicles, both pumps can be wired for full time duty to get maximum performance and are proven with 18.5 volt compatibility at pressures up to 80 psi. At only 5.1 lbs, they weigh half a pound less than competitive 1000+ horsepower pumps yet have twice the features!"

What's the most power anyone's run with E85 in a rotary?

You can read about suggested octane value of E85, but it seems a little vague. Unsure if the fuel becomes a problem before block and 1-piece e-shaft or not...

fuelab have some nice pumps too.

I'm running 2 ev14 725cc and 4 ev14 2000cc with a dual Bosch 044 pumps. I run a 15gal fuel cell. 23 lbs 480hp mustang dyno aprox 75 injector duty cycle. I think you might want to run 8 inj. Just to be on the safe side.

I tuned a car that made 829rwhp on e85 with 6xid2000, semi pp bw 480 1,32 a/r. Weldon 2035 pump

Yep me thinks 6 x 2000 or 2200 is enough fuel. 8 is way over kill for the turbo you have.

Chuck is on my ass on this turbo... :lol:

Sorry man. After trying many turbo's myself, I'll NEVER go with anything smaller then a T6 1.32 96/88 exhaust turbo if power was my goal. My motor is just a small secondary bridge and thinking about sending the exhaust wheel out to have it clipped to flow even more.

I don't know what you're shooting for, but my calcs for fuel went something like this, based on 100 lbs/min of air from a 75mm turbo. You probably will need more airflow by the sounds of it, with your "small" turbo lol.

E85 has a blended stoich of around 9.85:1, I'm sizing for a max rich lambda of .68:1 (10:1 in gas terms). So needs to support 6.7:1 AFR @ 100 lbs/min air, or 14.93 lbs/min of fuel (6.77 kg/min) Estimate of .78 kg/liter density for E85 gives you 8.68 L/min, or roughly 8680 cc/min of fuel. ID2000's max out linearly at like 88-90% at 13V, and about 2200cc/min of gasoline (would be a little more actually for alcohols due to difference in density) So 4 could hypothetically do it, 6 would be better, depending on your power goals. You might even be able to down-size the primaries for better idle if you wanted to.

There's nothing wrong with having too much injector to some extent. In my case I'm using 8x cheap Bosch 1600's, which although they suck on the high and low end of DC, are almost as linear as ID's in the middle, so over-sizing is better in my case to stay out of the <20% and >80% DC's where things get a little wonky.

I sold my s475. I am going to running a s482 fmw. Chuck has been busting my balls because I didnt go T6 with 96/88 wheel instead. I was told the new 87mm J-type wheel with 1.25 exhaust flows within 7% of the T6 96mm wheel but since its a T4, billet and w/ race cover it should spool quicker and can move more air. Well just have to see if it chokes out or not like Chuck is saying..

Thanks for the input on fuel and e85. I have not bought a pump nor injectors yet still gathering information.

By no means am I saying this turbo will not work. IT will and will work great. :nod:

use to run 1600 bosch primaries and they worked great. Idle and maxed out at 6psi at 8000rpms. Any smaller IMO would make it a bit harder to tune the transition. Cause now you have to go even bigger secondaries. Just upgraded my primaries to seimen deka 220lbs. Idle and start seems good so far. Looks like they will go to 9 psi and hoping that will allow my secondary injectors to come on at a higher PW. More in the linearly PW of the 1600 bosch injectors.

i have the holley dominator in tank. love it but im only at like 350 hp

Sk8, I saw you changed turbos, I just meant my calcs were for the S475 I'm gonna run. Sleeper7, that's a good point about primaries. I am currently using the ID1000's for primaries, and I've been worried about staging when I get it running with the 8x 1600 secondaries, I figured with the 1000's I had enough fuel to get into positive boost, but just. Maybe going with ID2000's for primaries to ease transition would be more ideal? I have an LT10s, which is bad enough for transition with 4 standardish sized injectors...

As for fuel pumps, 2x 044's will support ~480 LPH @ 43.5 base and 30 psi boost, which is only good enough for 8000 cc/min (and this doesn't even factor losses from lines, etc) http://www.jayracing.com/images/prod...osch%20044.jpg I have 3x 044's for mine, but I'm thinking about selling them off and going with a mechanical or larger single electric. But I'm lightyears away from running my heap again, lol.

Return it! no room for it unless you want to stay around the same power level.. :scratch: nah I'm just kidding but on a serious note I had a s372 with the billet wheel race cover and the 1.25 hot side. @40lbs on 760/1600's, street port, Ray made 710whp. Someone else on the forum at a high boost level with a s383 made 712 (I believe similar boost levels I could be wrong). But my point is that s383 is basically the same as the fmw... So i would not run another T4 hotside unless i was looking to make 700 or less. I'd say go with a "real" 400 frame and put that T6 behind her and let'er Rip!...just my 2 cent

What exhaust wheel did you have?

i use a weldon 1100-A pump.

same pump as mine but added a walbro for extra flow.

Killa. was looking at the HX60 turbo. Are you running the 96/92 exhaust wheel? and the 80 mm front wheel? Explains the great HP your making.

This off weldons site? Are you running it on e85 with methonal mixed in?


Current Fluids
Compatible with Gasoline Only (not compatible with alcohol / ethanol based fuels)

yes sir. 3 years now. one of the local guy has one in his FD for 3 years also with e85.

paper filters also.

I designed it, Gato fabricated it. Been running E85 for 3 years now with no issues. (6) 1600cc inj. 700+hp (3) bosch044's better safe than srry.

Attachment 648461

Making the switch to E85 and hoping someone could share what kind of 2 cycle they use. I normally use AMSOIL Dominator for premix but a tech from amsoil said that the E85 would not mix the same as 91 Oct and we make have issues with separation. Any thought?

Thanks:icon_tup:

Knew I should have kept mouth shut about using the weldon 1000 pump on E85. After 500+ trips down the track the last 3+ years it finally stopped working. send it out for rebuild and use it on another project. Great pump!

Just ordered Fuelab for this weekends race in Ennis.
