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.

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.
