03 We chose a Holley HP 150 fuel pump to supply fuel to our Hemi. This pump is rated at 120 gallons per hour at 9 psi, which is adequate for carbureted applications up to 750 horsepower.

We first got wind of Holley’s trick in-tank fuel reservoir mat when it was shown as a prototype at the 2014 Performance Racing Industry (PRI) show. The product idea was simple; reduce fuel ...

With both pump motors running, the Dominator 12-1800 can flow enough fuel to support up to 2,100 hp flowing 190 gallons per hour (gph) at 8 psi, or 140 gph at 60 psi for the fuel-injected crowd.

Naturally, the fuel-injected combination was run with Holley's new Dominator EFI system. The Holley Hi-Ram upper intake was designed to accept either a 92mm or massive 102mm throttle-body.
