Re: Fuel Pump Issues
If your running a 750 or bigger, on an engine that revs to 6500rpm and/or beyond, then going off mine and my dyno tuners previous experiences, Holley Blues have their limits.
The figure of 220rwkw was an approximate figure and depending on the application/use of the pump they are a good unit.
The regulator that comes with the blue is very restrictive and although 14psi sounds good, you really are never going to need that high a fuel pressure.
What carby are you running?
The flow rate of the Blue is what lets it down. only just. 7,000rpm on a clevo making 240rwkw it starts to get to its limits. oh and the noise thing gets to some people. not me though.
A Mallory or even a holley black are better units.
Hope this may help some :)
