Upgrading fuel need suggestions

[david harker]

Currently running gt40r on my gvr4 tuned to 29pounds with a 255 wb rewired and fic 1050's . I'm about maxed out and need to upgrade . I want to stay with an inline pump btw . I want to run around 35 to 40 pounds. Is it possible to do so with inline ? What injectors does everyone recommend ? Thanks in advance . Also have 8an line I'm running with hks fuel rail.

I believe that they make an inline and drop in Bosch 044, and it in conjunction with the wally should give you a good amount more go juice. Also walboro makes a 450lph pump that will drop in place of that 255.

Thanks

No prob, also Weldon makes some massive hi flow in line pumps. I also edited my first post. I noticed you said inline, do you have your 255 plumbed inline? If so, where did you mount it?

A 4303 in line. That's what land speed runs. I would have bought that instead of the 450 if I had known about it. Roughly 500 bucks iirc

Good call, that's a serious pump. Guess it's about how much more power you wanna make. You gonna be using e85?

I'm running inline now , 450 is prob what im going to run for now .e85 or race gas not really sure yet .

Depending on your budget you can also run a dual wally 255 setup from STM. Since you already have one pump already should only need to buy one more

Where does the second pump get dropped in ? Is it literally drop in and wire up ?

Its a hanger and yes it makes it a drop in unit.
