Thanks Jake :lol:
Hot, humid air is less dense than cooler, drier air. This can allow a golf ball to fly through the air with greater ease, as there won't be as much resistance on the ball.

This is amazing! I just joined the site because I am in the process of building a type IV motor for my 68 beetle and this site has the answer to every question I have thought of so far. I am new to the type IV scene but am glad I have dove into it because the possibilities of these motors are amazing. Thanks to everyone who has kept this site up and running it really is a masterpiece. :mrgreen:
