2 in-line pumps? I currently have 2 in-line Walbro GSL-392 and have taken them to 898rwhp on my old set-up last year. I'm expecting to hit the 1,000+rwhp this year with the new set-up, now some people have told me that I'm going to need a 3rd pump and some have said that it's plenty enough. So, I'm wondering if I could keep one of the Walbro and change the other with a Bosch 044. Would that work if you have 2 different pumps running in parallel that have different flow capabilty? I'm only thinking this co'z I'm kind'a being lazy of taking the fuel tank down again in able to add a 3rd pump. But if anyone have a real world experience of hitting the 1,000rwhp with just the 2 GSL-392 then I might just leave the 2 pumps in there, unless I need more. -Thanks in advance!
It theory 2 GSL392's will hit 1000rwhp, but it depends on your line restrictions & the max pressure you are trying to run. With -8 lines & low base pressure you should be OK. If you come up short, replacing one with an 044 should solve the issue.
