20HP, 9,000 RPM Engine Build! 88MPH Kart Pt. 3

We’re building an 88mph back to the future inspired go kart from the American Express 2.0 go kart kit from Go Power Sports. To achieve 88mph, we need a very powerful engine, which is why we’re building a hemi head Predator 212cc engine with really high performance and brand new engine mods, like a 24mm flat slide carburetor, elongated billet rod, oversized valves, and more. We’re taking this popular 212cc 6.5 horse power go kart engine and making it turn 9,000 RPM and put out about 20 horse power.
Thanks for Watching!
