Hey i been curious on how much the single Walbro 255 intank can hold...The most i made so far has been 510whp on Precision's 1000cc....Anyone else?

I'm about ready to hit the Dyno again with my built motor...I made 510 with my bone stock bottom end GSR...and i'm hoping for more now that i have my built motor



Would a relay help out alot??? if so what relay, thanks

 

iv seen a little over 700 but wouldent do it my self lol

 

570-580whp on e85

 

That would be a high reading dyno

 

Maybe i had a weak walbro but i was leaning out pretty bad at just under 550. Pressure was falling off pretty hard. Thats in a EF with stock lines. Dyno Dynamics Dyno.

 

I've been thinking of selling my Walhbro and getting a doucheworks 300lph in tank for a little more wiggle room. Hmmm...

 

No, you didn't.

A single Walbro 255 realistically runs out in the 550whp neighborhood on gasoline.

 

580hp. e85. h22.

 

506whp, 23psi c16 last year on my brothers car

 

592whp walbro 255hp & ID1000's on c16 but maxed out pump and injectors at that point..

 

i been told 600 is possibly with a relay, as long as there is constant voltage???

 

the 580 was at 13.7v.

 

I made 633whp with a single walbro not the best idea but I did it on race fuel..

Why bother though why not just get a single aeromotive 340lph pump???

 

i actually wasnt aware of that 1......whats the pontentioal on that 1?

 

more than the wally and as you see 550 is about the average max power the wally makes

 

i made 552whp with room to play on the same dyno.. C16 , stock lines with stock fuel filter.

 

I am only at 520 on e85 with a modded one and rewired. Plenty to go!

 

im thinking bigger wiring and a nice a relay

 

The Prelude made 670-680 on a single Walbro with a relay and 999cc MSD injecters.

 

583whp stock wiring and precision 1000's on sunoco 112 last year but I was 100% out of injector

PS- motor popped the end of last season so I don't recommend it unless you have 1200's

 

63*HP @ 26-27PSI on c16. rc 1000s@96%......with a b&m commandflo.......

 

also with a bosch relay.

 

Can u check out my build threaad? And see if you I can even make over 600 with my setup

 

what size amp relay are you guys using... For the f/b dual pump setups are you guys using two relays or one...

 

im not sure thats why i'm taking advice
