Anyone using this pump. Rated to 1000hp. Was wondering how loud it is. Considering getting one but don't want a pump that's louder than my exhaust. Have heard some really loud external pumps at the track.
I've seen a few local Supras who were running lean at 2 bar with dual stock pumps. In each case, switching to dual Walbros fixed the problem. The Denso may flow more than the Walbros at lower pressures but the Walbros flow more at 5 bar fuel pressure.Simba said:FWIW, the Denso Supra TT pumps flow more than the walbro 255's, especially at lower voltages.
