Yer not in boost all the time, when the throttle is closed there is little or no boost, are you sure you know how superchargers work?? Any supercharged application will hurt fuel mileage but who said anything about fuel mileage?? And don't be so sure screw types are "behind" centrifugals as you put it. I don't want too much torque? Hmmm so my daily driver can't have good suspension under it? I gotta run stock tires too? Well damn! I'll just go buy a 81 VW rabbit diesel then cause it doesn't have too much torque and it gets good gas mileage. By the way, I'm gonna recommend to the top fuel guys that they get a centrifugal because that roots blower is just a piece of ****. 
so all i have to do is downshift to match rpm to get the boost up if i'm driving around. Off the line lt1 has plenty of tourque on its own without boosted help

Seems like if it's a "per minute" number it would have to be based on a certain rpm somehow. I know the F1 max cfm is 1500 and the max rpm of the blower is like 50,000, are they saying you gotta turn it 50,000 to get that 1500 since both those are the max number?? I don't claim to be an expert on superchargers or math, these are the numbers that whipple has up on their site.

So the max cfm is achieved at the max rpm on the procharger?? I didn't know if the max rpm meant that was the safest you could turn it without it flying apart or if that's when it would run out of breath. I'd like to know the cfm numbers on roots blowers, I've never been able to find that info. I know that say a Weiand 177 will move 177 cubic inches of air per rev but that doesn't give you cfm. Anyway, I'm depressed, I destroyed my lil 10 bolt tonight at the track and the trans went out in my truck a week ago so I'm hoofin' it right now. Looks like I'll be putting the 3:42 back in tomorrow just so I can get to work monday. lol
