I ran the red on a motor with 427 HP & 425 tq. It fell on its face, every time at the track, As did the holley blue. Went to the mallory, and later to the holley black testing them, back to back at the track. I picked up 3 tenths & about 5mph. With the black & mallory over the red & blue pumps. They are not a good choice, in my opinion. Just based on my findings with my car. I have head of people getting away with using them. But for my application, they did not work. No matter what it says on paper, sometimes real world results are different.

Roger That!
I'll always defer to the voice of experience. Sometimes things look real good on paper and they just don't perform under live conditions. Another glitch can be when a product doesn't perform as advertised. It sounds like several people have had problems with the Holley pumps..

I had Holley Red, but it was really loud... I changed it to an EDELBROCK QUIET-FLO™ ELECTRIC FUEL PUMP... very quiet!

Glad to be of any help. I have been down the road of spending, way to much money on parts that just did not work out.
