Frequently Asked Questions

Q: How does this kit increase compression?
A: This kit includes a specialized .012" thin base gasket. By reducing the distance between the cylinder and the crankcase, it effectively decreases the squish clearance, resulting in a higher compression ratio for more "snap" and power.

Q: Will I need to change my fuel mapping after installing this?
A: Whenever you increase compression, it is good practice to monitor your jetting or fuel mapping. Higher compression engines can be more sensitive to ignition timing and fuel octane levels.

Expert Pro-Tip: Since you are running higher compression, ensure your cooling system is in top shape. A thin base gasket is a great performance value, but the engine will generate slightly more heat. Always use a high-quality coolant and double-check that your radiator is free of debris before hitting the track.
