lol
when i get enough $$ to build the engine.
but im happy now =]

 

that thing looks beautiful

 

Good idea

I'll put together a full E85 fuel kit in the next couple weeks as I install both this setup and the ProEFI on Tom's G35.

Thanks again for the feedback guys. We can also do this with 2 pumps and cap off the 3rd port for a dual setup.

How does the pump on the drivers side work? Will it not start to overfill the other side? Or not be able to supply the other side fast enough?

 

Looks NASTY!!!!!!

 

Looks like a quality piece, but I have to question no venturi/siphon system. The gas tank capacity is effectively 1/2 now? If you are running a pump on the driver side to push fuel over to the triple pump, how are you keeping it from running dry and burning itself up? Also does this require a new pump and pump hanger for the driver side also? Has this system been tested and can utilize a full tank of gas?

 

Hal, all you need is sensor in the driver's side tank (Like the one that turns on your low fuel light) wired to a circuit to control the pump. It is actually quite simple. You also do not need to run it all the time. I shut them off at idle using outputs from the ECU (AEM or ProEFI) I am sure the Haltech can do this too? We do the same thing in corvettes.

 

seems like alot to do....if it is a Daily driver. at what point would it just be easier, simpler, and cheaper to just cut out the spare tire well and drop in a fuel cell with a big weldon or aeromotive pump?

 

Not really much more work. It took us an hour to mount up the stock pump on the driverside hanger, wire it,etc.. Add another hour to install the main hanger, relays,etc.. it's not bad at all.

Externals are terribly loud, and cost wise the weldon pump to support the same type of power of this hanger will run you $800+ then add the dial-a-flow for "street" driving, and the fuel cell.

Sure it's not for everyone, we don't claim it is, just another offering for fuel.

Do instructions come with the assembly to show all the wiring? More for the necessary changed made to the driver side hanger. If so, then sign me up for one!

 

Bump for Lar and Chris on their engineering and foresight skills. Having cut their teeth in the Supra world, like us, this will be a "must" in the very near future for big VQ builds. Props!

How does a setup like this affect fuel temps? Having three walbros pumping, plus another for the driver's side... Seems like you'd be transfering a bit of heat into the fuel.

I'm sure its not prohibitive... Just wondering if maybe a fuel cooler would be a smart move on a setup like this?

 

You are rarely running all 3 pumps at once!! One runs all the time, the second comes on at say 10 psi and the 3rd at say 20 psi.

The Driver's side pump is also rarely on! All computer controlled

 

Great news! We have a VERY simply solution for those that do not want to run a pump on the drivers side to push over the fuel.
This is used in oem production and is out of another vehicle. I've added the part to hanger contents so you pay nothing more than what I stated earlier.

It's a small jet valve that is inline with the return on the pump and pulls the fuel just like factory!

Here are a couple pics

How would you plumb the pumps to the rails? Is there a fitting that allows 3 -6AN fittings to connect to a -10AN? Then just run the -10 to another Y before the rails?

 

A bit of info regarding multiple in tank fuel pump hangers.

The Sound Performance triple pump hanger does away with the canister as you guys can see in the pics, and that's a good thing. What we're finding is that when multiple pumps are installed, they'll drain a stock sized canister in less than 5 seconds at when pushed to full bore.

From Viper Alley by Final GTS.. This applies to all multiple intank pump setups:

"4. Single-Stage, Multi-pump in-tank systems are nice and easy & keep fuel temps down if staged, but require decent fuel levels as they wll not work too well with surge canisters. "

Draining the canister creates a lean condition under WOT which as everyone knows is devastating for a motor. Think of two or three pumps dropped into a 1 liter container of liquid be it fuel, water, etc. Think of how fast multiple pump swould drain that container; the same thing happens in your fuel tank canister. What we recommend is if someone reaches the point where they will need dual, triple, or even quad Walbros [as we're producing now], that they not let fuel level get below 1/8th tank for hard turns or WOT operation. That cures any starvation issues under WOT, and also daily driving.

These hangers are TOP shelf quality, and are meant for the enthusiest that drives his car hard, and wants to make mega HP. It's a hardcore nononense approach to proper fueling, and HUGE thanks to Sound Performance for bringing these to market. In my humble opinion, these are far auperior to anything on the market in design, and function.

Thanks !

^^Are you the same cowboy bebop that has that insane Twin Turbo V8 Supra??? That things is simply amazing!!!!!!!!

 

If I didnt consider Chris and Larry to be friends, I would rip you a new one. You lack a lot of information and experience in the design and function of a surge canister. Experience with "hangers" doesnt count.

But on a positive note, i see this as the only bolt-in solution for the type of vehicle that requires *3* fuel pumps.

 

+1 ?

 

Ye'sir.




Feel free to PM me, man, I'm always open to hear the other side of the arguement. I'm aware of how surge canisters work, and the ups and downs associated with them and I firmly believe on this triple hanger they have absolutely no place.

Thanks!

Eric
