have a 572 10-71 intercooled BCC w/2 1290's And I run a product engineering system. There a liitle pricey, but imo the best continuous duty pump around. I ran this same pump on a 605 14-71 intercooled BBC w/ big chief heads and 22 lbs boost at 7200 Rpm. Pumps have an awesome warranty and reputation. You must run a return line form the pump. They also make boost referenced regulator, which is way cool, but I just run the conventional style.

I'll see if I can find their web address when I finish posting.

The web address is www.productengr.com.

There are several factors on fuel pump selection. CI, RPM, BOOST, BLOWER SIZE, CONTINUOUS DUTY???, AND ARE YOU GOING TO RUN A FUEL RETURN BACk TO THE TANKS????
In my situations, I have always run the 4450 pump/filter combo0 that puts out 460 GPH. Its better to have too much, and return it, than not enough..

Good Luck, Steve

Agreed, I am going mechanical as well and all have highly recommended Clay Smith pumps. Seems to be a universal thumbs up.

I don't have a way to run a return to the tanks, I want to keep it simple. Will a clay smith be sufficient? or should I try elect in line with the mec? how much does a clay smith pump flow?

"KISS" Keep it simple stupid. Words to live by. Call Clay Smith, ask for George let him know what your building. I did the same thing 588 blown BBF 12-71 hampton... NO problems... No return lines... Just used a Magnaflow pressure reg.

did you run a return? they told me I will need a return line to run it
Im running an electric holley pump (to prime the system) and the mechanical clay smith. The problem with my old mechanical pump was when I was trying to adjust my regulator, it would not allow me to go over 6psi. With the new clay smith pump it handles much more psi.

Carter makes a great pump that will keep up just fine. I've run it on 950 HP for three years now, never under 7 Pds with full 10 Pds boost. Better yet, no regulator and the less parts the better in my book.
Part #M61045 AND>>>>>>>>>>>>>>>> $130.00!!!!!!!!!




Big-time fuel flow for big-time performance.
Big-time fuel flow for big-time performance. Carter Competition Series Race Super mechanical fuel pumps deliver big-time fuel flow. Their free-flow output is 172 gph. Despite this high capacity, their compact size means that they often fit where other high-performance pumps won't. In addition, they're ''clockable,'' which allows rotation of the inlet and outlet. They have heat-treated, high-speed levers, plus -10 AN inlets and -8 AN outlets, with fittings included. With 7 to 8.5 psi operating pressure, no regulator is required.

Freeflow means without back pressure. Will there be 130GPM actually reaching the carbs?

That said, there are GN boats near 1000 hp using the Clay Smith mechanical pump. They use them because they get the juice there and are reliable.

Dont forget to use radiused fittings and smooth bend angles...
