WHAT. a serious amount of current???

At 4bar it is around 16 amps. that isnt much. they sell 100 amp relays. and getting a 40 amp fuse is easy. lol.

I plan on 2 in my bird but was just wondering if anyone else is using them. At 120 a piece you cant beat it

So a single Walbro 400 is good for 1029 HP in turbo applications...damnnn you only need one...2 is over kill

Steve your not going to use those 255's? get 2 of the 340's intank. small, little current draw and very quiet. I love mine

denmah

well, i could not get solid numbers at the time, and cant believe everything on the internet.

other flow tests rate them at 800crank, others say 800 wheel, like mentioned, 120 a piece is cheap...

figured if i ever put in a built motor and a 91mm turbo i would never have to touch the pumps and tank again.

oh well.

BTW guys he is planning to run e85 so fuel system will have to be slightly overbuilt as compared to pump gas

denmah

be careful there are gasoline 400s and e85 400s

foose04 ran the gasoline 400s with e85 and they burned out in a year or less

You can use the E85 models for both E85 and gas right?

Where are these being found for 120 each? Or is that for the gasoline model?

I'm actually planning pump I think and maybe some meth. Ebay has them for that. The stealth pumps are nice but I'm not wanting to spent that much. E85 would be every once in awhile.

i got them for 120 a piece with the install kit on ebay

The only difference between the gas and e85 version is the sealed connector for the pump which makes it ethanol compatible and a couple bucks extra.

These look bigger than the Aeromotive 340s or the similar Walbros, will 2 Walbro 400s fit in a factory Fbody tank? If so than maybe these are what I need to feed 1300HP worth of E85.

M&M Turbochargers

the 400 walbro's seem worth considering

That is so cheap. I love it. Have a friend running one in his e85 talon and loves it.

The ethanol version is good for 700+ whp at 7300 rpm on a 4.8 LS. 10 feed, -8 return.

The E85 units are shorter, have a different PN, and claim to flow 450lph? Either way 700+ on e85 through 1 pump is impressive.
