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.

Daddy Dave switched to twin turbos because he needed more HP and could not fit a BIGGER pro charger on it (no front end room if there was he would have seeped with the procharger) he didn't want to get a different car so he had no choice but to go to twin turbos.
As for Pontiacs head design we have the Warp 6 and DCI's RA5 heads!

With my small blower set up (compared to a 12-71 or 14-71) all I can make (boost wise) is 11.5 lbs and I have to spin it almost 30% over (which is a lot for a roots blower of that size) to do that, even with that I'm making upwards of 1,400HP. So boost wise I'm maxed out...........i need a BIGGER blower. I couldn't imagine what my engine would make with a 12 or 14-71 on it......well over 2,200HP! Remember its not the size of the blower or how much boost can make its what you can do with what you have.....ive been working on my combo for a while! A lot of people just turn up the boost as oppose to working on a certain combo....not always the best thing to do.
