Hi guys, im finally getting round to upgrading my fuel pump to run 1 bar boost. Was running standard pump with boost via bleed valve but after a couple weeks it started detting, poping banging etc so i took the bleeder off. It still occasionally dets on standard boost so to be safe i havent used WOT above 4500rpm for a while (no matter how many scoobies pass me). OK, so I know my pumps had it.
I'll be putting a surge tank (cause im racing in hillclimbs) on the rear undertray next to the exhaust back box. I still dont know which bosch pump to use (not getting walbro cause I can get bosch cheaper). What bosch pumps are you guys using. Hoping to get one to cope with about 250kwatw (for the future). Do i have to go for an 044 for this or is there something better suited (and cheaper)????Not sure about using a 910/920 cauce the flow difference at 5 bar is substancial form the 044.
Finally, i wanna run the fuel return line back to the main tank to keep the surge tank fuel cooler. Is my standard (and half shagged) pump running at relatively no pressure going to flow enough to keep my surge tank full enough. Is this setup going to run the surge tank dry cause the bosch pump (despite having a lot higher resistance) will out-flow the other pump?
Ive had a lot of conflicting opinions from experienced people out there so PLEASE HELP!!
Thanks,
James
