I went the return system route. Not sure if it was the best idea since it took longer to tune but I now have dual Walbro 255's feeding 650rwhp and we are going higher. I'm more comfortable with the pressure not jumping around on the race track.
Im not sure which route to take. I am shooting for 550whp when I get my engine built for it so maybe I should stick with the returnless. but then again you can always upgrade right. the return style kits are like $2K right?
Nowhere near that. Figure 2 Walbro pumps, filter from Aeromotive, and then a couple of Y-connectors and lots of hoses. I also have a 22 Gallon Fuel Cell in the back too.
