However, there are a few rules:

1)   Compression check your motor before deciding to Supercharge it. All cylinders should be within 10% of each other to continue. If any irregularity shows, a cylinder leak down test will tell you what and where it is. These things need to be corrected before supercharging as boost will magnify any problem by the amount of BAR added. If it the rings or valves couldn't seal before, it'll be even worse under boost!

2)   Never run lean. Install and use a reliable air-to-fuel gauge like we provide and run at the boost levels we specify and no harm will come to your motor.

3)   Emission testing is your responsibility. A properly tuned supercharger can pass emissions, but this one is out of our control. Get a good tune-up, adjust your air-fuel mixture correctly, and you should be fine.

4)   Don't send a boy to do a man's job, and don't take our STREET kit and RACE it. We have a RACE kit for that. The STREET kit we sell provides 9 pounds of boost quietly and reliably with a belt-driven impeller. Quiet, low maintenance, lots of fun. Can safely go to 6,000 RPM and back for years with ordinary maintenance. But - take it above 6,000 RPM, race it non-stop for 30 minutes, that sort of thing, and you're going to wish you had the gear-driven RACE supercharger kit we sell.
