I currently have a gen II 2.3l whipple on pump gas making 608hp 550tq on 17pds. How much more power would I get if I sold this 2.3 an bought a 2.9? Can someone give me some numbers on what I could expect on pump gas. With the 2.3 on torco it makes 663hp on 22pds. Would like to have those numbers on pump gas. Idk if there is a thread like this so bare with me. Thanks
