Paxton fuel pumps?
Sniped a Paxton fuel pump (160 GPH) on Ebay..
http://cgi.ebay.com/ebaymotors/ws/eB...141750239&rd=1
(6 seconds before auction end)
I don't know too much about Paxton pumps.. Won this pump on Ebay as I'll need a 2nd fuel pump for my nitrous fuel supply ('m going to run 2 separate fuel systems). My other pump is a Aeromotive (Summit brand but it's a aeromotive pump) 140 GPH/18 psi pump. Now I wonder if I should use the 160 Gph/15 psi PAXTON pump for the carb fuel supply or if I should leave the 140 GPH/18 psi pump for the carb fuel supply and use the 160 gph pump for the fuel supply for the nitrous system. What's the best solution? I also don't know too much about Paxton pumps.. Don't know anybody that sells them. I've read somewhere that they are the same as aeromotive? Does anyone know anything about Paxton pumps?

I think aeromotive makes paxton's pumps as well. The motor casing looks oddly familiar. I know I have seen paxton pumps that look just like the A1000 pump.
I really don't think it matters which pump you use where, they are so close to the same rating. I guess I would decide which one you feel is more reliable and then install that one on the nitrous system.

Sell them both and get one big pump, a BG 400 or something similar........one hic up from either of those pump and you will be buying a new set of pistons. I understand budget builds; but some things you can not do on the cheap, or at least you should not.

I do have the low pressure safety switch, so I should be ok in case one of the pumps craps out.. Large pumps pull large amps and I don't want to have a large pump drawing amps when I don't need it. I run a alternator and drawing more amps is costing me power..

There is a reason why all fast cars have one big pump or two good pumps; its because it is the right way to do it. If you are going to build an 8 second car you have to spend 8 second money...........now, or later.
I have no faith in hobbs switches; there is a reason why you will not find them on any serious race car.

For your combination the fuel pump would be one of the last places I would be trying to save money. You might get away with what you are trying to do, but all it takes is one momentary failure and you just bought a new set of pistons, and rings.........at a minimum.
8 second budget race car, is a bit of an oxymoron.

I've had great luck with the BG 400 pump. Although I do have a Holley black pump on a second sump from the tank for motoring around the pits and down the return road. The Holley pump uses far less amps and saves wear and tear on the BG pump. I also run both systems with the nitrous on, just in case. Just recently we blew the fuse on the BG pump. Thank God we had a second one.

Put a full throttle switch on the alternator so the alternator shuts off for the 12 seconds your going down the strip.The battery "can" do without the alternator for 12 seconds and that will make the alternator draw a non-issue.

There are lots of ways to cut down on parisitic losses in a race car, but there may be a trade off for it that may not be worth the 1-5 hp you get out of it.
