Because I have no idea what im doing. Im trying to get to 600hp most of what ive came up with are suggestions from others. This is my first serious build. Ive done 2 others but the were just basically rering and bearing jobs. but i want to use the tunnel ram.Im learning as I figure trial and error is the only way to go. I dont really have anyone around me that I can pick there brain. If you ask on here you get 10 totally different answers.
