YouTube star Rob Dahm has finished his billet four-rotor rotary engine and it is time to strap the all wheel drive Mazda RX7 onto the chassis dyno. The wild contraption made more power with every pull and began gobbling down Ethanol. Luckily, Rob relied on Holley's VR2 brushless in-tank fuel pump system to keep the party going. The brushless fuel pump controllers were switched from low output to maximum fun and a glory pull was in his sights. Let's not spoil the ending, but you won't want to miss this video!

If you're interested in learning more about our brushless pumps, check out Rob's video discussing how he integrated them into his build. Holley Fuel Cell EFI Pump Modules come with two controllers and harnesses to give you VR fuel pump power inside your fuel cell. The modules were designed to drop in as a direct replacement for your existing 12 bolt flange fuel cell cap assembly. The billet top flange includes an 8AN inlet port, a 10AN outlet port, and a fuel filler cap. The fuel pump depth is fully adjustable from 7.5" to 11" deep. The module kits include all the hardware to install into your existing fuel cell. All that you need to add is your fuel line.
