what is the advantage of a belt driven fuel pump?

I'm looking for a fuel pump for my T60 setup. I want to eventually run E85 if that makes a different. Planning on running 20lbs of boost and shooting for 450 to 500 whp.

Flow. It's overkill for 500 on E85.

agreed! Those belt driven pumps are made for mega HP and 450-500hp is considered average hp for todays rx7's. I'd say a bosch 044 and a kenne bell boost a pump would do you or a supra fuel pump or an a1000 or etc... etc... etc... Even weldon electric fuel pumps would be over kill for that car and that's a step down from the mechanical belt driven pumps.

Think an A1000 with -10 lines is too much?

Im confused about the 044s are they an in tank unit out of tank, or one in tank and one out, or can they be configured in any way?

The 044 is traditionally an external pump but can be used either way. The correct socks for them are kind of hard to find so I would search around if you are looking to make it internal. I know the correct one is a box type sock and the wrong one is the small normal style sock. I've heard reports of the smaller socks actually getting sucked into the pump causing it to clog. I used mine externally and it seems to be doing fine at least at 400hp. I'm also using a kenne bell boost a pump set at 20% right now.

I can't really give you advise on that as I've never run two pumps before and would hate to give out the wrong advise. I can say that most of the people on this board run dual pumps over a single with a kenne bell so I'm sure someone can chime in on this.

whenever i'm doing a fuel system i always overbuild cause you never know when you wanna run more boost than you planned originally so i built my car with the belt driven pump. dynoed it on sunday with e85 made 509 hp at 15 psi. going to 30 psi soon or more depending on the competition. always overbuild fuel system especially on a rotary. just my two cents as i'm no genius here.

Are stock fuel lines good, Im not trying to be cheap but new fuel lines and fittings could cost a small fortune.


The more I read the more I am starting to lean towards a single fuel pump setup, the bosch 044 in tank with the boost a pump is probably the best bet.

I guess I'm worried about restriction due to pumps in series.

I am also worried about starting a pump while it is dry.

Not really worried about noise.

Best person to talk to about stock fuel lines and how much they hold up is Jrat. I believe he got something like 500hp or around about that much on stock fuel lines. I've also heard from quite a few different people that the stock lines (if in good shape) can handle 500hp.

As far as starting the pump while it's dry, just make sure to have the pump located at the bottom of the fuel setup/tank and you should have no worries.
