I read that if you pute a supercharger on something, your going to need to do something to reduce the compession ratio or you can blow up your engine. I read on another forum link that someone pute the 3800 supercharger on their 3400, but it didn't last very long. They did have to modify the lower manifold to get it to fit though. Damn the limiters, 122 mph isn't fast enough. I hear the Jet Chip by passes the limiter.
Trying to translate the 247 kph, looks to be about 153 mph. I'm not 100% sure, but that's about what it looks to be when my speedo gos up to 150 mph, and just below that is 240 kph. (about 148-9 mph)
