Single Pump Intank Fuel System To Support Big Hp

[Daz]

I'm currently running two pumps intank, I want to change this to just a single pump system.

Anyone recommend any intank single pump system to support 800 to 1000HP

Also must be compatible with e85

Going into a r33 GTR

Thanks

I think you may need to go external, although you can still mount the larger (2000hp) external pumps intank apparently.

With the G forces you are heading towards, you should be more worried about fuel surge...

Looks like internal set up is coming out to see how we (you) can mount this 2000hp pump Scotty

Lol. I want to do somthing along this line. But its way easier to just run a surge tank and as I plan to run 3 external pumps. 044's. Im planning on having the stock pump fill the surge tank and have it overflow back to the stock tank. Im hoping this will be good for about 600hp to the wheels.

Would think 2 would be plenty. I have one 044 in my car and its way too noisy - I'd hate to have 3 of them - there are better (and cheaper) options these days - but I believe yours is a track only car (or drags).

Having a PWM controlled pump is critical in a road car, so as not to overheat the fuel. Plus, not many of the larger pumps like running 100% duty for long.

Using multiple pumps without some method of making sure they are working properly is a good way to lunch an engine. I run twin Walbros, one feeds each V6 rail, so if one fails, the engine just runs on 3 cylinders.

Totally agree, and they are only rated for 70 hours life span on e85 apparently.

^^ 500 hours.

^^^ Yes single pump for safety reasons

I'm just getting a Fuelab external. They have a built in speed control, 0-5v input which I'd imagine most ECU's could deal with.

Could be worth a look.

[scotty nm35]

That's what I bought, Fuelab seem to be one of the only brands to have the speed controller built in, and I am pretty sure they can be mounted intank with an appropriate filter. No idea why you would want to though, at that sort of power you need the surge tank anyway.

[XRATED]

Don't fuel lab do big in tank pump kits too?

Unless you baffle the tank correctly, or only spend your 1000hp on dyno's then surge it is.

[tricstar]

That is how noisy the magnafuel pro tuner 525 was.

Whereas the Fuelab (1500hp) pump can't even be heard at idle (only running at 22%), wish I did it ages ago.

I'm looking into the fuel lab pumps now....

If they are mounted external must they be used with a surge tank or can they draw fuel up out of the tank?

[XKLABA]

That is a good question, my weldon can be mounted in the boot and draw from the main tank but it sounds like the one in the video and that is with it being controlled with a PWM speed controller

[XKLABA]

I to am now looking at a Fuelab Prodigy pump, just a matter of which one is going to match my Weldon 2025-A closest, probably the 42401

Will mean I can run my PWM signal straight to it is simplify my wiring

Has anyone had one of these for any lenght of time ?

How quiet are they ?
