Gearhead Fabrications

Stage 2 Hellcat Durango beating up our Mustang Dyno and putting down 804WHP on 93 Oct and stock exhaust!!

Holley Gateway equipped Charger Hellcat putting down 1366whp on blower and 1580whp on a 200 shot!!

Stage 4 track hawk putting down 913whp on pump E… not a bad little driver..

Here we have a new Hellcat with our stage 3.5 package and a Holley Gateway set up.. This baby made 732whp on 93 octane then with just adding e85 to the tank she made 946whp.. this is with no pulley change and no modifications. Other than changing the fuel once the Holley is set up. It takes care of everything. We have also set this up with a selectable power switch, yielding a valet mode, full trash control with limited throttle ramp, and an all out mode with doing nothing but turning a switch!! There is so much more we can do with these gateway set ups. Call us with any questions you have before ordering yours.
