I'm still using a 255 pump on my car. Running a nats wassit above 450.

My understanding is...

Walbor 255l pump rated to flow fuel up to about 450hp ish.

So it depends, if you are aiming sub 450 the Walbor will do the job
If you are aiming above 450 - a Bosch pump will flow more when you need it

 

TOTAL IMPREZA tested the walbro 255 and 300lph and the standard factory pump was better than the 255 as it locked out just under 5.0bar the 300lph was slightly better than its sister but they also tested the TOMEI & BOOSH MOTORSPORT 044 the tomei was fantastic but the best by far was the boosh m.s 044 running in excess of 8.0bar.....seems that most opt for 1 of the walbros but acording to tests these are no better than the standard factory pumps as the factory pumps can cater for upwards of 490bhp.

 

That article was misleading.
From memory - It was comparing the latest newage pump. Factory pumps prior to that could now way flow enough for anywhere near 490hp
So ignore that article. This was brought up on another thread on here anyone got a link
