Milo500 Posted June 13, 2016 Share Posted June 13, 2016 Hi, almost finishing my single from twin build. I have a 340ph pump sat waiting to go in... The question is, is it big enough lph for around 550bhp? Or do I need to go for 400lph or 450lph? Also is Kemso a good brand, or is it just worth only going for walbro? Cheers, Tom Quote Link to comment Share on other sites More sharing options...
Wez Posted June 14, 2016 Share Posted June 14, 2016 With fuel pumps I would stick to known brands. As for flowrate, I ran as did many others a single Walbro 255 to around the 550-600hp mark. If I was in the market for a pump now I would be looking at the Walbro 485 from SRD Quote Link to comment Share on other sites More sharing options...

Milo500 Posted June 15, 2016 Author Share Posted June 15, 2016 Is the 340ph one I have now too much then? Can you have too much pump? I was always told that 255lph is no where near enough flow at 550bhp ish ... have I been told incorrect info? Cheers guys Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted June 15, 2016 Share Posted June 15, 2016 You can't have a pump that's too big dude, as the fpr will only allow the rail pressure to reach whatever the regulator is set to. The 340 will be fine Quote Link to comment Share on other sites More sharing options...

Milo500 Posted June 21, 2016 Author Share Posted June 21, 2016 Does a 255lph pump really go above 500bhp? As the past thing I want to do it buy one and me to run out of pump on the dyno when getting tuned. Quote Link to comment Share on other sites More sharing options...
