What Lift Pump For E85 Setup

[tricstar]

I'm just changing a few things for E85, and noticed my intank pump looks like standard ? car has surge tank with Magnafuel ProTuner 525 inline pump etc

-8 feed, -6 return, I'm assuming standard pump as lift is not enough, so what pump should I be looking at ?

To support 650+rwhp on E85

I think you would be surprised, the stock pump will flow very well at no pressure. As long as the return line goes back to the surge tank also you should be fine, worst case you would empty the surge after a few minutes of WOT, which never happens.

ok

I do have some 1000m runs coming up and was a bit worried about that ( emptying surge tank ), might knock up a bigger tank for that event, just to be safe, current tank is only about 1.5L

should solve that problem ?

Heading to Racewars eh?

A nismo pump might be a option rather then a new surge tank. ~25% extra flow over stock....

It might be best just to run some rough calcs with the your current set-up....max fuel usage@ WOT vs flow rate between tank and surge tank and surge tank and fuel rail etc and see where your going to fall short.

yep.. Racewars.. thought I might tweak a few things first (-:

just done fuel lines from Magnafuel pump/surge to rail so that should be fine, any idea what the standard pump will flow, pumping to no pressure??

once I know that, if its not far off what I can use @WOT + surge in about 20seconds then I'll know where I'm at

[wedge_r34gtr]

STOCK = 195L/hr @3bar advertised, but has been tested to flow up to 250L/hr @3bar with voltage mod.

NISMO= 276L/hr @3bar advertised, but is also said to flow 25-50% more then the stock pump.

^^use worse case scenerio for calcs.

I was going to try to make racewars, buttheres just to much stuff to do my car before it's ready for any track/drag stuff...so i guess maybe next year :-(

Your injectors can only flow 2L in 20sec at full tilt and your stock pump should flow about 1.4L at 3bar (as above) in the same time with 13.8V so you shouldn't really run into any issues as it will actually flow more than that because there is less pressure.

yeah I'm just going to rewire the pump and I should right

cheers guys
