The bigger the turbo would make more power per psi. Charlies turbo is tiny compare to ur blower. I made almost 1265 hp at 15 psi and my turbo was on the smaller size which is a 91.5 mm with a 1550 hp rating. I need a 98 mm for my 482 and that is rated at 18-1900 hp. But I want to drive it on the street so I wanted a small one. If I wanted to make a big power on lower boost, I just need to put a 106 mm on it and I believe it will match ur combo but that is just an example. But the turbo shines when u up the boost! Not a lot of hp loss driving it unlike the blower combo. Not arguing but stating the facts. Look at Daddy Dave at SO! He said he will never put a turbo on his car and look at his combo now. Twin turbo just like everyone else. The only one left is Megalodon and just a few guys and few nitrous cars. But turbo is the way to go for big power based on the cars running it. But what do I know. Converting to Turbo is just hard on a Pontiac due to the head design exhaust we have. This is why a lot of people are converting to LS.
