As a matter of fact...I did put the spinning exhaust tips on! And to prove the electric supercharger works, I noticed that the exhaust spinners SPIN FASTER! I got at least 15hp out of the exhaust tips and 50hp out of the supercharger, and I did not have to do all the work that Quick LS is doing!
The faster the spinning exhaust tips spin the more vacuum they pull on the exhaust system and this lessens the amount of boost required of the electric supercharger! Thats why the whole thing works so well. Its a "system"....exhaust tips & electric supercharger!
