Yup, whereas the standard pump will struggle at 230bhp.
The walbro pumps also make a racket. If I ever get to the point where the s3 pump isn't good enough I'll fit an inline walbro as well.
Thats bollox about the Bhp capabilities (not saying you are talking bollox - just the internet in general), i can back this up as i have 350 bhp on a 8v pump, 580cc injectors, big turbo etc etc and it flows more than enough
however, going for custom map soon so walbro it is. these can cope with 700hp and is the pump that everyone uses.
I am going for a inline one, so the original will still be in the tank also..
only noisy if you dont insulate ;-)
