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?

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.

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.
