well the 255 is supposedly rated at 500-550 rwhp at stock pressure. With meth injection u may be able to get 600 wheel out of it. Every setup is different. I think its best to over fuel than not have enough!

What would be a good pump upgrade? I read a little about the walbro 450 but seems most people use it when the switch to E85. I see aeromotive has a 340 pump. I'm going to get rid of the corvette filter/regulator and go with a boost referenced fuel pressure regulator of some sort.

We have personally tested the 255 to 600rwhp. Using larger fuel line will cut that back a little, but not much. we have dual 255s, dual 340s, single 340s, single 450s or dual 900s also.

Shoot me an email and we can get you set up with whatever you need!!

Message him to see if he has one. He is a good guy and will respond. I got mine from him and i messed up on a bad ground and he helped me out. The pump was fine..it was my dumb mistake on the ground.
