Walbro 255?

[Black99X]

Okay I'm wondering if I need to upgrade my fuel pump.... I'm runnin a walbro 255 and looking to push 28psi out of the 2.4 gt35r- .63ar- the injectors are 880cc's??? I think I might just go with 2 255's let me know what you think.

I was fine with a single 255hp on my racecar. 133mph on it without the ntrious with 850's and a single 255hp.

It is not the hp- I think I will be okay for anything under 600whp-

I started running out of fuel around 400WHP. I went to a 255HP and its been fine since then. Part of it could have been that my old "sock" was kind of dirty. An HP is cheap enough, just upgrade the one in the tank or put a HP in line and leave the current one in the tank.
