Walbro 255 Fuel pump

So guys what do you think should I improve in some places or am I pretty good, I just wanna make over 400whp.

Only thing I don't like is your fuel pump, I'd get an aeromotive 340, I just never liked walbro. Just my 2 cents.

everything but your fuel pump sounds good

Fuel pump is the limiting factor here.

Thanks guys ill look into getting the aeromotive 340 instead, I even thought of maybe the dual pump set up or would that be over kill, ok im alsi thinking of premixing to not sure

Grab a new fuel pump, and some quality plugs.

Never had a problem with my Wally 255.. But not sure it will support 400rwhp maybe 400 bhp. What size line you running?

That being said I'm going for 3-4 at the wheels this year with 3/8 lines (-6)... But next year looking for closer to 5.. Then -8 and aero 340 or Walbro 400. Not sure which yet...

Your turbo is flowing enough for 750 rotary whp.

Im running -6 lines right now

I'm not 100 percent sure but I think you will be ok to mid 3s...? Over that probably good idea to upgrade.. Hopefully this spring ill be having Elliot tune my car w/ 255lph.. We will see when I run out of fuel...

Im running the 255 never had a problem yet but now im thinking of going to a bigger one haha thanks guys! Haha

So after doing some looking if you have the 255lph HP and not the oem one it says its good up to 700hp

700 piston hp? If so that's considerably less rotary hp....
