I'm starting to think that buying a walbro for a stock turbo fc is a waste of money. The injectors max out before the pump it seems so far. So if one gets larger secondaries at what hp is the stock fuel pump maxxed out?

isn't this question kinda hard to answer especially if one had a standalone and what not? i always thought it was around or right under 250whp. i can see what you are saying if someone was using the stock ecu. but what i want to know is how exactly the higher fuel pressure will buffer your afr's especially when the stock injectors are maxed like revvin said.

I'm gonna have greg put a fuel pressure guage on the car, see if the pressure starts falling off, then dyno the car.

yes, why are your injectors maxed out? cause the fuel pressure dropped? did you rewire the pump?

My fuel pump is not maxxed out. I'm just curious at what hp the stock unit gets maxxed out.
