Dual walb 255 pumps...4-500 hp?

[gaboonviper85]

So I'm getting things organized now and would like to start collecting parts for my fall/winter build....I'd like to get a dual pumps so if i want more power I don't have to change my whole fuel system...I want to do it once and forget it! I'm ordering 20' of -06 braided line etc so I want to get a new hanger that accepts an fittings...will I have problems tuning with safc or maft pro with all that fuel? Is two pumps too much? Will I still be able to adjust enough with a afpr?

I want 400hp for sure but I want the car set up so if the time comes for a holset then all I need is a tune instead of buying more parts and removing all the shit I already installed.

Also...is -06 good enough for fuel feed and what size should I get for fuel return!

for 400-450 u should be alright with 1 walbro, after that i'd recommend dual walbros. you should be alright with -6 return, u could run that also for feed, but if anything i'd do 8, also dun for get a FPR. What turbo are u planning on using btw?

For now just a 57 trim ct 26.....I got to fix two oil leaks first and repair some misc issues but when I get the car home it's gonna be parked.

I know one 255 is enough but I was gonna get wesbeech dual pump hanger as it has the an bungs already welded on....so I figured I'd get two pumps just to have them so if I go bigger I won't need to drop the tank again...figured I'd kill two birds with one stone as I have nothing but time and I'm in no hurry to drive the car....so is two pumps too much fuel or will an afpr do it's job well enough to not give me issues?

Wouldnt just setting the fpr to where you want be all you need to do? Even with two pumps all the extra pressure would be bled back into the tank.

depending on size of lines, size of injectors. he just wants reassurance for the future.

I guess you could get real slick and install two and have one (or both for theft protection) switched.

One step ahead of you. ;-)

Flow is the key.

Wow, somebody planning ahead and playing it safe. Well done.

You don't need even a 255 for 400 rwhp. But having extra head room is a very good thing.
