If I am reading this correctly, I believe you mean flexwheels instead of flywheel and intake instead of loader. Am I correct or did I read this wrong?

In my opinion, there is no need to have a topic dedicated to different intake designs. People should be researching on their own to find out what type of intake they want to use. Look through reveal videos and other forum topics. There is a great one you can find here:
