I am running a Kieth Eickert pump bottom upgrade from CP Perf on my Gen V 454. I draw through a BIG Wix water separating filter with -8 lines all the way from the pick up to the carb. This pump makes 6.5 psi except at WOT where it drops to 3. I have mixed feelings about it, as the pressure drop is a concern. My motor doesn't lean surge (plugs look fine) and seems to run fine so far. Its a 525sc with a small pulley and intercooler.

I think 3 psi at WOT is way to low.Mine with the electric holley red pump idles at 7 psi and drops to 5 at WOT and if I run for a long time at WOT my O2 sensors show it leaning out.This is also a reason for me to upgrade.Maybe some experts will give there advice on the 3PSI.

Navy,
I can see your concern. As you are not seeing signs of low pressure, I wonder if your FP gauge might be reading low at all pressure levels; 6.5 lbs at idle is also low.

BenPerfected 10-16-2007 07:53 PM
As there seems to be a pressure doubt with the KEPP Gen V pump, maybe they would ship you one to try. If it doesn't hold 5.5+ lbs at WOT, you can return it for credit. If it works out, you agree to buy the second Gen IV pump.
All get to see the results on OSO. Either way, KEPP gets good press for good customer service.

LOL! Still runnin' my kids in tubes @ 18 MPH and 80 MPH @ 6,000 RPM/ blown 498 @ 8 psi on the Carter 10 psi on the 420 blower!!!.... How many years now????? KISS!
