Racepump

[HighVoltage 329]

Has anyone run a Howard Stewart Racepump fuel pump? I am setting one up on a blown carb 555" chevy replacing my cam driven pump. No return line required it's so simple. Will it work?

Never used one but they seem like the hot deal??, but you will need a regulator with carbs!..

I have used them with great success. You have to use a regulator, but you don't need a return line, they maintain line pressure no matter how long the boat sits, and they require less HP to operate than a standard pump. Very trick deal.

I will be using the racepump regulator with their pump. I red that it holds pressure even when the motor is not running. With the cam driven pump I could loose the primp if the gas got low in at the end of a long race. Then wouldn't reprime without filling the carb bowls and firing the motor. I hope this pump solves that problem. Will the pump build pressure by just turning the motor over?

i believe the race pump is a sort of diapraghm/ check valve type pump ,so im sure it will hold pressure.......national dragster advertises them everyweek in the newspaper.
im curiuos to know what kind of load its putting on the cam to generate enuff fuel for a 2,000 h.p. deal?

I have one on my BBC...naturally asparated...just under 700 hp. It's piston driven and works well. It'll run at 7700 rpm with no problem. It does not like to pump dry. I usually prime my carbs after changing jets...kind of a hassle but I've gotten used to it now. Does require a regulator (I have a Barry Grant) but does not require a return. It looks cool, light weight, compact, etc. and very simple.

I'd still stick with a Clay Smith and save a bunch of money!.. :rolleyes:

I don't think a Clay Smith will support this much hourse power. 1200 plus
I've run a Clay Smith with an electric. I am hoping this racepump will keep up. It's so clean and simple.

1/2 lb of gasoline per horsepower per hour @ sea level. 1200HP divided by .5 = 600lbs. 600 lbs divided by 6 = 100 gallons (SAE, 6lbs per gallon) 100 gallons plus 20% margin = 120 gallons per hour @ sea level. I think any pump that will flow 120 gallons + per hour (at a reasonable pressure) will do the job for you, if your plumbing is not restricted.

i run a clay smith 600" blown deal with dual 1050's never missed a beat in 3 years just my 2 cents

More proof that it works!.. :cool: :cool:

Comparing the RacePump to a standard old-style mechanical pump (especially comparing price) is like apples and pears. The closest thing you can compare one of these to is a high-end electric pump, like an Aeromotive.
There are a few tricks to the RacePump that none of the other pumps can touch. One is that it maintains line pressure and doesn't need a return line. Another is that it doesn't have any diaphrams or parts that need to be replaced like a standard Holley or Clay Smith pump.
It also takes less power to operate, and they make versions that will support fuel injection. Lastly (and most important in my boat's case) it is MUCH smaller than a standard pump, which allows it to fit between the motor rail and the exhaust manifold, where a normal pump flat-out wouldn't fit.
Here's a link (http://www.automedia2000.com/racepumps/rpreleases.htm) to the latest RP press release for their marine pump. Pretty much tells the story. Not to say there's anything wrong with the other stuff on the market, this is just a different approach using new technology.

A few images to illustrate what I'm saying about the size:

id still like to see the wear it will put on the cam with time.........mech is great for circle but for all out performance....www.productengr.com

Clay Smith is a great pump and puts out 140 GPH. The Racepump puts out 205 GPH and is now running on the Vector.
My consern is will the racepump hold proper pressure under hard excelleration?
I don't want to dammage the new motor.

I've seen testing on full-blown alky motors where it can maintain pressure for extremely long periods of time. The key is to use a good regulator. The pump puts out SO MUCH volume and pressure (WELL above the 8 pounds or so usually required) that the regulator cuts it down, so even if there is a slight dip, you never see it at the carb end.
