[QUOTE="03SBSNAKE, post: 13691205, member: 134313"] This is not a myth if you think it is then you have never had a car that you did a lower swap on. I have a posi ported blower with a 2.76 upper that made about 480 rwhp and 470rwtq. I added one thing a 4lb lower and my numbers went to 490 rwhp and 530rwtq. This works because your peak torque is in the lower rpm's and a larger lower pulley gets it spinning faster in the lower rpm so you have more boost right when you hit it. [/QUOTE]
