Watch this to the end to hear this engine make a few pulls! This is a 521 cubic inch, screw-blown Hemi engine that runs on alcohol and was built by Kilpatrick Racing Engines in Waukesha, WI. This video was filmed at World Wide Technology Raceway during the 2022 Builder's Brawl No Prep racing event. #engine #engines #horsepower #performance #hemi #hemipower #tuning #testing #supercharged #shorts ]]> Tue 29 Nov 2022 10:35:49 +0200 https://www.gnarpowpow.com/videos/19222/kilpatrick-racing-engines-521-cid-hemi-roars-to-life/ https://www.gnarpowpow.com/videos/19225/screw-blown-521-cid-hemi-engine/
After getting blown backwards off the starting line from Jim Kilpatrick's alcohol-fueled, screw-blown, 521 cubic inch Hemi engine at the 2022 Builder's Brawl, we stopped by the Kilpatrick Racing Engines / Bad Judgement Racing pit the next morning to get the full details of this engine build.
