I did a Waterman Cable driven, rear mount, belt drive, MagnaFuel Outlaw 750 fuel pump setup on my 98 Boosted LQ9 (LS1 type) Camaro. Wanted to do a quick write-up on it here as it can be very confusing and overwhelming when you start looking into it.



The first challenge that I had was with space out in front of the balancer in order to attach a mandrel to the front.





This would be the easy way.



Here is a Mandrel with cog pulley all in one pictured above.



In looking around I stumbled across this hub from ATI with the cog machined into the back where I have plenty of space. The outer shell must be removed from the old ATI Damper if switching over like I did. If not, you can buy it complete from ATI with the Bolt and Washer. The standard length LS1 crank bolt does not work with this hub.



The bolt is like 1.5 inches longer. ARP does not make one in this length. I called.



Gotta have that $30 washer that was not included with the $40 bolt.



OK, so next you need the correct style and size pulley. I turned to Robert Ette from AEI CNC for that. The pumps want to be driven at 50% crank speed.



Next you need the drive bracket that holds the pulley. I was fortunate enough to get a slightly bent hand me down from my buddy Steve Smith which I took to my Metal Experts, LLC buddy David Huggins to get flat.



Here is an Enderle version of the same thing more or less.



This is the back with the female hex that the pump shaft would slide into or in my case, the Waterman Cable. That blue flange typically comes with the pump and attaches it to the drive bracket.



Next you need to attach the drive bracket to the engine. AEI, Mightymouse Solutions and others make these for the LS type motors. Here is the AEI bracket. David Childress please feel free to post pics of yours as well.



Here is a setup mounted with the AEI.





I opted to make my own with the help of Metal Experts, LLC.





So that's the front in a nutshell. There are some stumbling points here. First, there is an Aeromotive pump that does not use a drive bracket and has the shaft for the pulley right on it. That shaft is a smaller diameter than the standard used by all the rest. Again, All the rest use a hex drive that goes into the back of the pulley drive bracket.

Once the engine bracket is in place and holding the pully drive bracket and your ATI cogged hub or mandrel with crank pulley are installed, you can measure for the belt and get that coming.



On to the back. Because this is a rear mount setup, it adds a little complexity. The Waterman Cable is hex male on both ends.



You have a female hex up front already and just require the 3 bolt flange from Waterman with the male threaded ends to attach the cable.

But in the rear, the pump is male hex. So you need a coupler. The coupler must be supported though. The easiest way to do this is to get the complete kit from Waterman for the cable. I did not know this until after I had embarked in an other direction as the information that I originally received from Waterman was either misunderstood by myself or the guy that I spoke to. This bracket setup receives the male hex and allows the cable to screw right on the other side plus give you a mounting option.



I got a bit more involved in my solution and went with 2 bearing points. I basically converted an Enderle hex extension.......



....into a coupler by buying the pieces and doing some slight modifications.

Slight hiccup here.

Tadda



On the pump





Still had to come up with a mounting solution so cute this on the waterjet. DXF Creations & Vector Services





Finished product



Pump mounted and cable screwed in.



I didn't get a chance to get some shots with the plumbing installed. Hopefully there is a break in the rain tomorrow to get some more pics. Also found a spot for the foot long regulator. These belt driven pumps put out big volume. Mine is rated 7 gpm. That's enough to support 2500 hp on the e85 that I'm running. So you have to use a regulator rated for the volume. This Aeromotive reg is good for 13 gpm.



Here's a video of very first totally cold start with the belt/cable setup. This is without any real tuning besides what I did to get it running initially the other day. No cranks prior to this video in 72 hrs. No check valves.

Apparently nobody reads the Fuel section. LOL

I have been looking into doing a setup like that. How much do you think you have in it $$$$?

Very cool write up Los.

You getting your car together for the winter?

TRIXLSXSUPRA

Nice to see you posted this up here Los.

The pic of Bob @ AEI CNC's pump mount is mine here are a couple more for anyone interested Bob is awesome to deal with can't rec'd him enough!

I needed "options" to clear the turbo manifolds, exhaust turn-out, as well as the inlet/outlets of the FP so he obviously set me up with plenty lol!

Sorry didn't have the ATI hub installed when i snapped these pics though...







Here it is with the Enderle bracket and FP

I'm currently working with bob on this bracket as well. But the balancer hub has been extensively modified to also work with a rear mounted trigger wheel, and I'm going to do something to try to integrate my engine limiter in with his bracket. Will be a very trick setup once I get it all finalized. I'll post up some pics when I get it all sorted out.

Bob is a great guy to work with. Very responsive.

with a cnc machine and a big hunk of aluminum anything is possible! one day i will make the leap.

great bracket by him, and nice job Los sticking with the project.

Just to help add some hopefully useful info to this great thread i'll post up the parts from when i call Waterman as their website is hard to navigate and doesn't list all the parts etc.

#252025 (Adapter) $52
#252031 (Chassis bracket for round tube w/ cap) $194 / (for flat plate mount) $168
#252040 (Adapter for Enderle FP) $93
#252016XL (HD Cable) $348 for first 6ft and $23 for each add'l ft

Cable needed (standard vs heavy duty) will depend upon flow rate of your FP or at least that's what they say! I actually think they have 3 different types but that's what was rec'd for my Enderle pump

Sorry if the descrpitions are not exact these were just off the notes i jotted down a few months back as i did not end up running a cell in back.

It would cost about $2K to replicate the fuel system

Get back to leak hunting, slacker.

She's ready to rumble for tomorrow if this weather clears up.

How's life working under the new Holley Overlords?

LosLS2

Good stuff. Yes, they make 3 cables. The light cable, standard and HD. I was told that the standard (which I am using) was overkill for my setup as it is good to pumps that deliver 13 gpm and mine is only 7 gpm. This cable is $160 for the first 6 ft. My cable was 138" long for reference so it worked out to just under $250 for the cable shipped. If you are going cable drive, buy the kit as it includes the first 6 ft on the standard cable as well as the rear mount coupler/bracket and the 3 bolt cable flange for the front. I did not do this as it was not explained clearly to me and I was led to believe that the rear coupler/bracket alone was $350.

LosLS2

Yep, Bob is solid and please share pics.

Low blow! shes going 8's on Friday.. leak or not

System looks really good BTW. Not having it up front is going to save you so much BS in the end.
