Quick question. I have a single Walbro 255 in-tank pump, return system, stock wiring. How much horsepower can the pump support? The truck will have a single MP70 turbo and 60# (3 bar) injectors.

How much more will a hot wire kit get me? Thanks!

 

Check my sig. No dyno numbers, but those times are on a single 255 installed years ago.

 

500 to 550rwhp

 

I'd say this is pretty accurate for a truck.

I had a racetronix with hotwire kit in my camaro and it started to lean out at the 600rwhp on N2O.

 

Thanks guys, I will probably go ahead and do a hotwire kit before I get the turbo on.
