I need to put together a fuel system for a turbocharged 370, 80-88mm single, hoping for around 650-700 RWHP. Is it nessary to spend the money on an Aeromotive A100 or eliminator pump and controller or will (2) 255 liter Walbro pumps do the same jop just as good? Oh I almost forgot I will probably also do an E-85 tune and 92 pump gas tune.

Induction parts I already have: GMPP single plane, Elbow.com, 90mm TB, Speed Inc rails, 96 Lb injectors, AEM driver box, A1000 regulator, and Aluminum Dual outlet fuel cell.

Dual in-tank is the way to go imo

If you already have the alluminum sumped tank I'd just go ahead and get a big external pump. Alot of guys are getting away with 2 or even 3 walbros but I've never been a big fan of those setups.

the aeromotive eliminator is a bad *** pump but the a1000 will do just fine for the power you wanna make.with a good aeromotive pump you wont have to worry about running out of fuel and it leaves you plenty of room to make more power down the road.

2 walbros are good to go to ?

Two Walbro fuel pumps will work just fine, unless one of the pumps quit working and you don't know it. I know of people have had to rebuild their engines due to this happening. Bob

How about a Weldon 600-A? Are those any good? I've heard they outperform the Walbro units (and cost about 3x as much) but it might give you the extra fuel you need to hit your goals without going to one of the big pumps.

It would be a simpler install... only one part to fail (the pump) and if it goes, you'll know it. Contrast that with a dual Walbro setup either 1) causing a lean condition at WOT because one of the pumps failed and you didn't know it because the other pump kept the car running (as discussed above), or 2) the boost-activated switch fails, if you chose not to run both pumps all the time.

I think the Weldon has a significantly lower amperage draw than one Walbro (255) pump, let alone two Walbro pumps.

+1. Great pumps. Quiet and don't require a voltage regulator.

Thanks for thinking of Weldon.....yes, the Weldon 600-A and it's big brother the 1100-A are very good fuel pumps. Unfortunately the brush compound is not compatible with E85 -- tried, just can't do it. Not sure of any high performance electric "flow-through" fuel pump that is completely compatible with E85 (I am sure they are available) -- we've tested a few of them and it tends to affect the comm/brush interface (basically coats the comm and destroys the brushes). If he was running gas, the 1100-A would be a better choice since it will flow 110 gph @ 80 psi and is only drawing 14 amps.

On a side note -- all of the billet bodied or cast bodied Weldon Racing pumps are fully compatible with E85, Methanol. racing gas, and even nitro (with an oring change), as our their filters and bypass regulators.

Do you run it all the time? How do you deal with the oem regulator in the tank? I'm guessing your boost referenced and just wondering how fuel pressure climbs above the stock 58-60 psi?

Thanks

I run the 4301 and it's great. Not sure how it would like E85 however.

My dual pump kits will support well into the 1000+rwhp range.

They allow perfect streetability & will provide all the flow you need for a very reasonable price with an easy plug-n-play install.

Please call to discuss at 724-322-8505 9:00am-11:00pm eastern time, including weekends.

Mr.Big

Yes and No, the stock pump runs during non boost driving then a hobbs switch activates the "big" pump to go into higher psi mode under boost...

So list of pumps that will work with E85 and support 1000+HP? Right now I'm planning around 650ish at the wheels but I plan to step up the power next year.

Twin Bosch 044's will support what you need and room to grow in the future. Better than the 255's IMO.

00Wildcat

twin bosch 044's are more than a single A1000 or eliminator for that matter.

Im not a fan of multiple pumps, simply because if one fails the car will still run fine, and you wont know anything was wrong untill its too late.

I run a Magnafual MP 4302. I dont have many street miles on it yet, but i've heard nothing but good things about them in continuous duty applications.

The Aeromotive pumps are not meant for the street they will over heat and burnup in a hurry without there pump controller which helps but still not a fix all. Pumps like the MagnaFuel do not require a controller and work very well as street pumps.

For one you should make alot more power than 650-700 with an 88mm turbo? But if you just make 700rwhp and use E85 you will need 950 worth of fuel flow 2 Walbros would cut that but not have alot of room to grow. You already have an aluminum tank sumped so a good external pump setup is the way to go and can be setup to get you some cushion room to grow. The Weldon's are great pumps but as Jim said are not good for E85...The MagnaFuel pumps are very good street pumps and work for E85 we use them in alot of our systems...We are testing the new Fuelabs pumps and they are doing really well too.

First off for right now this is a stock '03 LQ4 rotating assembly, I will at a min build a stock block 4340 forged 370 by this time next year in search of 1000+HP. I like the simple idea of running a single pump. I'm going to weld a water tank on to the side of my fuel tank modifying it is no big deal to me. I'm thinking in-tank pump/s plumbed into existing outlet/s is a possibility for cooling and noise. I think the aeromotive can go intank, but please correct me if I'm wrong. That as a primary + a 255 Walbro for back up When it's time to step it up may be the way to go?
