Not a lot of info on them here. Is there complete bolt on kits available? Anyone rig up their own? I found this thread below from Los who builds excellent rigs but thats all I found. Any info on these pumps systems post up!

That's the only one I know of. Here's a link to where he posted it on yb, I think there was more discussion and ideas on there: http://www.yellowbullet.com/forum/sh....php?t=1608218

You need to contact Bob and AEICNC he can make you a kit with all the pulleys/brackets/etc

Then you just buy a pump/waterman cable

Id be interested in one.

If anyone wants to do all the hard work and make a kit

And then sell it to me for cheap.

I have been looking for just a complete LS belt drive pump setup. All I keep seeing is BBC kits when I try to do a search.

Indeed. I would have to think a one and done package would be a good seller considering the popular and growing boost market for LS. Fuel supply is the most essential ingredient for a good boost build and it seems everyone who goes mechanical says electric is a waste of time.

An ideal set up would be one that runs off the factory serp. A set of brackets, new belt part number, pump and cable would be a winning combo

Agreed. It seems it is almost common for these engines to be pushing 1K plus horsepower. I am at the point where I either need to upgrade from my single 4303 or just go belt drive. I see a lot of good reviews of people doing this on dual purpose street/strip cars.

Easiest thing to do for belt drive is this -

1. ATI Balancer - Part# 918852 (This has a 25tooth HDT hub built into back side of balancer to drive fuel pump belt)

2. You need to ensure the pump spins at 50-55% speed of crank so you need a 44 to 46 HDT size pulley to put on the shaft of the mechanical fuel pump. Dailey engineering is literally the only out there offering this pulley for an Aeromotive pump shaft size. See link.

3. Aeromotive fuel pump - Atomic 11115 part number. This pump is good for at least 2000WHP on methanol. Most likely won't need much else.

4. Aeromotive mount - 11706 part number. Holds the pump. Has slots to allow for belt adjustments.

5. Call Bob at AEI tell him you want to mount all of the above and where you want it all and he will make you the final mount.

Done deal.

Excellent. Thank you for the info!

Where is everyone finding the longer crank bolt and washer?

ATI lists part numbers but nobody stocks them

Whats the price tag on all that after you're done?

I don't get the appeal... Seems like it would be 2-3x more expensive than going with electric pump(s)

Unless you are running methanol at huge power levels, cost VS performance doesn't add up. Any of the big boy $500ish electric pumps on a boost switch with an AEM380 to cruise around will make 1500-1600 on E85 for under under $650...

I think LOS had about $2k in his rear mount cable driven setup.

I think the market for this is people who are maxing out a single 4303 and looking at going duals.

You also don't have flow rates falling off when you drive high pressure.

This can be tossed together between 1500-2000 depending on how you setup brackets/pulleys.

Even if that were true… The mechanical pump still doesn’t make sense cost wise. If you are maxing out a 4303 buy another 4303. Or as mentioned buy a smaller 500ish HP E85 pump that is quiet. Like an AEM380 for $150. Then have a 4303 come on in boost. Don’t get me wrong if someone were to offer me a mechanical setup I’d take it… that doesn’t make is cost effective.

mshadow

Two 4303s is around $950

You could piece together a cable driven setup for $1500 or less if you're creative and don't mind the crank drive coming out the front of the crank pulley. The ARP hub adds $200 and buying brackets from AEI also drives up the price but you could potential repurpose something else or build your own.

So $950 vs $1500 and never having to worry about fuel delivery again or a single pump failing.

I would imagine most people at that power level are less concerned with budget.

There certainly is a cost threshold to consider as well as a performance goal. Looks to me once again that 1000hp is more or less the ceiling for 'budget'

I cant believe that rings true 1000hp is considered BUDGET?





My thinking is this is more a decision based on how much you love the car your building, or love racing. If either of those rank super high on your goal list? Mechanical is your best route.



If a supplier were to get their pump kit at a price point that can compete with electric? I think a LOT of orders would be heading your way

What does “piece together” mean exactly?

The pump mentioned is $800+ buy itself. That’s without the $100+ pump bracket and $100+ pump pulley. The balancer is over $400, plus the balancer pulley to drive the pump pulley (which the price isn’t even listed $100?) Plus the bracket to mount the assy to the engine (price not listed? $200?). Plus the cable drive assy… I’m not seeing $1500 there.

Comes down to what you need I guess. How much power are we talking? Are 2 4303’s needed? 1 4303 setup properly should net about 900whp on E85. Do we need 1800whp worth of pump to justify running 2? A single AEM380 for $150 will suffice for most and support 1400ish easy for roughly $625 combined with a 4303.

Not to mention you can always simply add another pump… for example 2 AEM380’s in parallel flow more than a 4303. You could run 1 AEM380 constant and have 2 more kick on in boost. For a total of $450ish. Hell run 4 AEM380’s for $600. You’ll never have to worry about fuel delivery again. With 3 pumps kicking on while “in boost only”… they will last forever.

Not to mention there is large used market for fuel pumps. Rebuilds on 4303’s are cheap. I paid $60 shipped for an overhaul on mine after 3 years (and I bought mine used with unknown mileage) You could pick up used pumps pretty darn cheap.

If your setup is done correctly with AFR fail safes, a pump failing is not big deal… So arguing the “peace of mind” point isn’t really relevant either IMO. If you don’t’ have AFR fail safes setup on a 1000+hp setup… you should.

Here’s mine. Wanted to do it once and be done. Fuel pump drive on the left. Rear mounted cable driven Magnafuel 1000 pump.

You can buy a power steering pump with a rear side connection to attach a second device like a fuel pump.. At least some midget/sprint engines do that.. Or some dry sump pumps can have fuel and power steering stages stacked on the rear..
