Those guys know what they are doing, when the 4stroke guys said the turbo raptors will not success, the K&T guys show them what they can do with it and now they are holding the record on the open class single cylinder with their Turboed Raptor
The RZR 4 was a customer car. Yeah that turbo kit rocks. The Weber was running a ton of boost! The orange S made 100hp at the wheels on the dyno and the purple S made 150hp w/the bottle and 138 w/out. That is some serious power considering a supercharged Ranger 800 only made 55hp on the same dyno.
