Walbro 255 Fuel Pump, When is it needed?
I currently only make 278 whp and I plan on taking my car to ~330 whp. Will I need to upgrade my stock fuel pump? How about injectors and fuel rail?
I found a similar post in the Evo X forums and I know that is a superior stock pump but most stated that stock fuel pump is good to 400 whp.
Quick side-question, I dyno'd 278 whp on a supposedly low-number Dyno with a handful of bolt-ons. Anyone know how the stock numbers might look?
