I'd run more than a -6 feed to both rails with E85 at the 900hp level. You're looking at .75-.80 BSFC!

yeah that's what I was thinking that's why i did -8 feeds with two-6 to the regulator. that's factory crossover tube will only flow 400 horsepower.

my 670 thru a th400 was with the factory crossover

I'm hitting 650 with a factory crossover. No issues.

High impedance injectors are needed for an LS1 PCM. But, you can run low impedance injectors on the LS1 PCM with an injector driver box. Acceleronics used to make one.

For injectors that huge, low impedance will be a better bet for you. Getting that thing to idle on high impedance injectors that big would be a task.

factory crossover starts to become a problem at the ~700hp level. Obviously on E85 it'll be a restriction at <600, it's like a 5/16" line...

A1000 isn't going to cut it. Aside from the fact that they aren't very reliable, they only move about 600 hp woth of fuel. Running 2 of them sets you up for an engine meltdown if one of them takes a powder. I'd look at something like a Weldon 2035 or equivelant.

Also, on injectors, the old Bosch 160s idle like crap. They aren't linear down low. Check out Injector dynamics I think it was, they have some fancy new linear 1000cc and 2000cc injectors that idle like a kitten.

Dual in-tank Walbro's could do it for you...There's a few DIY's on here about them, and they're good to somewhere around 1000 hp I think?

Not on E85 + boost.

^ Good call. Forgot about the E85 part...got stupid for a sec.

i vote fuelab 42401..... I have a 41402 and it flows 2.5 walbros worth of fuel, built in pump controller on them too. The 42401 will flow 190+ GPH at 3 bar should be plenty for what you're trying to do.

when i said the crossover would only flow 400hp i meant the 3/8ths line will only flow 400- I know guys have made more but with the stock configuration you would be asking for trouble.

if you made 650 with a factory cross over that means that tube was only flowing 325 of fuel.

I know the a1000 isnt the best pump but i got it new for 100 with a filter so im going to run it. Its going to be a while before i put the screw to it and i can always upgrade the pump later. I still need to build the headers and convert to the ls1 pcm. thanks for the info



hell i might just scrap the e85 idea- who knows- atleast i have the injector and line to do it if i decide.

the way i look at it is yea the crossover is 3/8th, but so is my feed line, so that crossover will flow atleast 800hp at the motor. ive been thinkin bout cutting the stock feed line off and welding on a -8 fitting onto it and run -8 feed and leave everything else stock.

Ive had an a1000 with a BAP for over 5yrs. No controller. I usualy have it set on 30%. 633rwhp (old t76 kit) thru a glide/nitrous convertor(turbo car). Pump gas and ford 160lbs inj. Swapped to a bigger t-6 kit w a GT47-88, added 20% fuel for same boost (flowing more air) and still no problems yet..

I designed my system around volume, not so much pressure. -12 feeding -8's, rails, -8's, FPR, -6 return. Set for 39psi no vac. Remember, as pressure increases the tradeoff is flow.

Those fuellab pumps look promising! Anyone use them on the street?

http://cgi.ebay.com/ebaymotors/FUELA...Q5fAccessories ok what gives? 1800hp thru -10 ports? I dont think so. BTW look in ITEM SPECIFICS it says its aeromotive??

They do advertise a -10 port on the big pumps my "little" 41402 has -10 ports, flow test sent with the pump was ~170gph at 3bar.

I'm using mine on the street, not too many hours on it though, maybe 12 hours of runtime on it at 50psi. I don't have the PWM hooked up off my DFI yet due to laziness, so it's running 100% and it makes a lot of noise

I remember reading years ago about there being a plastic tube of some kind inside each rail. Guys were removing this on the higher hp builds to avoid the restriction it caused. Trying to find the old pics but no luck yet. Is this only on certain year rails? Maybe it was a 1993 only situation....

There were a lot of failures reported right after the fuel lab pumps were introduced. I haven't seen many lately though. They are promising pumps but I'm waiting on a solid verdict on reliability before I strap one to anything I put together. Staying with Weldon until then, I know exactly what they do and they are very consistent with top level QC.

I was looking into the 2035 or 2345 myself, but I wasnt interested in having to run a controller. I really want to try e85 but with what a PITA it is to get around here I never did.

That pump sure is loud! Is it hard mounted by chance? Any idea as to why the ebay listing says it crosses over to an aeromotive number??
