I know A&A uses them for their twin pump fuel kit. http://www.aacorvette.com/supercharg...roducts_id=435

Lots of guys with blowers making north of 750 use them with great success.

 

Thinking about this route..

 

I have only seen one set of these in person and they are in a TT 5.3 Mustang. The owner told me they have performed flawlessly. I'm assuming around 600ish rhwp.

I talked to the owner of Hinson Motorsports the last time I was there and he also told me that they have used these pumps and have not had any issues in the cars they have installed them in and said that they should be fine for around a grand at the wheels on the corn.

I can't decide if I am going to give these a try or not.... I guess I will have to see after some more people use them.

 

here's a couple pics run 2 of the 12-1800hp pumps with surge tank!! cheers

 

Wow, how much hp are you running to need two!?

 

So are they now rated to be run with e85? On the chart it just shows gas and diesel.

 

Dont forget, that when used at normal EFI pressures even on normal petrol, the 1800hp claims fall well short.

More like half of that.

I guess running 4 pumps like that can make sense. They are a neat package, and when all are running it is overkill. So at least even if one fails, you still have an excess of fuel.

 

what's the reason for the surge tank? is any of the pumps on a hobbs switch?

 

Easier and cheaper to have a pump fill a surge tank at low pressure and then have high pressure pump(s) kick on pulling from surge tank when under boost.

 

Correct.

Main reason though is it eliminates any surge problems with having a large main tank, and fuel potentially sloshing away from the pickup

And saves any mucking about modifying the main tank.

It seems less common in the US, as you mostly drag guys just seem to sump the tanks as fuel only goes rearwards.

But an external swirl, surge, whatever you want to call it is a pretty easy and versatile way of building a solid fuel system

 

Was kinda hoping one of these would be enough to support 800whp using 127lb injectors e85

 

You should be fine. I'm running the 12-800 with 120lb injectors, 45psi base pressure and E85 without any issues. I haven't had it on the dyno but at 14psi, 3250 race weight I've been 9.44 @ 142 (mid 700RWHP based on most calculators). I've had it up to 23.5psi for a brief moment and didn't show any signs of fuel starvation.

 

my setup made 801 rwhp with this pump/FIC 1000s/e85/17psi boost @ 90% dc

 

Awesome, thanks guys.

 

Just curious,anyone take theirs apart yet? The body looks like a good size housing for a couple of 340lph in tankers.

 

reason for surge tank has been answered by others!! I actually maxed out 2 of the walbro e85 450lph pumps @ 24psi and 1148rwhp and rapidly rising hence the reason to go 2 dominators and a new tank !! should go 1200ish on pump e85 will know soon yes its setup on 1 pump and at 6ish psi kick in the other 3 !!! street strip wagon !!! cheers

 

More than likely that is what is inside the housing.

 

you'll be fine at that level. I run 120s on E85 too.

 

Bringing this back up anyone in the 1K+ hp range with these pumps and how they holding up?

 

Just had a pump fail in my 12-1400.
