Hello everyone,

Putting my fuel system together and decided to use different pumps. I have two un-used Grannitelli 365's, I believe they are but don't trust them since they have been sitting for over 12 years and I remember some were having problems with them back in the day.

I've got a FORE fuel hat and going with a two pump set up.

Any suggestions on reliable pumps in a two-pump setup that will supply enough for about 1000 hp?

Full fuel system
Wiring Upgrade
80lb injectors
W/all the necessary add on's

Thanks, Mel

Will 80s supply a 1000?

I have dual dw300s. They're 340lph each and I make 700+ on e85.

E85 takes about 35% more fuel.

In theory these would support 900+

Thanks Dusten,

That's one I'm looking at and it may be the one. They do make a dw400 but they sure are pricey.

I made 770 with 60's so they should get me close.

Dual walbro 450's should do the trick

Thanks friend. I will definitely give those a look.

That must be a record. Because most run into issues in the mid 600s.

Based on 90% duty cycle a set of 60s is maxed out at like 650whp

Perhaps with FP turned way up. Some tuners did it long ago when 80s were hard to tune correctly and nothing else was available yet. I would worry a bit about spray pattern issues at real high pressures. But it should deliver enough fuel QUANTITY. Maybe at poor Quality.

As for pumps? I use Aeromotive 340s for 700+ RWHP on boost and another 100-350 shot on top as needed.

I was on a 100 shot with race fuel and the dyno numbers were 770hp, 889tq.

All I have to go by are the dyno sheets and that is what they say. If they are incorrect, I have no control over that.

Race gas and spray. I'm guessing a wet shot.

So your injectors were making about 650... At their limit.

I was quoting mids 600s on pump gas.

You are right... Wet shot would be adding fuel outside of injectors.

Not doubting the numbers at all. But now knowing numbers were with a 100 shot, it is reasonable to do with the 60s.

Not a problem. I try to convey the most accurate information I can however I'm not immune to being wrong. ✌
