I understand the idea of high velocity in a small pipe with back pressure verse larger size less back pressure and Low velocity. The above chart reads in cfm flow and hp. So single 3" can flow 747cfm and 339 hp. That would say that the 243 heads I have on the motor need to flow 373.5 cfm each. Which I don't think this motor can do NA. The hp number is what has me puzzled. My 08 Duramax has 3.5" after the turbo and before the cat and 4.5 after thru a single muffler (can't remember the brand of the catback system ) motor is 325 hp 600+ torque stock. Probably not the same since it's an oil burner.
I am just thinking it would be different. Maybe put a large nasty chrome tip on it.  |
I think this will look pretty cool. Large single pipe on the back. It will probably end up flowing better than duals. Lookin forward to seeing that one put together.
