Well thats one opinion. But then look at Tim Huspen and his orange '86 coupe running 8.20's around 170mph in the quarter. He has a blow thrue 351 with an F2 ProCharger, which is a centrifigul blower..cant be that bad.
I would rather have a turbo on my car just because I you dont seen many turbocharged mustangs on the streets around here.
However your arguement about the positive displacement blower is purely your opinion. They are very overrated. Sure they came out on the 03/04 cobra so they gotta be awsome right? Well, not so much for alot of power on the street. Traction is a huge issue with big hp roots/twin screw street cars. They also cost alot more and are more of a pain to tune. Also what happens if you get caught out in the rain? Even 400rwtq with a positive displacement blower is gonna get squirly on wet roads. Take a centrifugal blower or a turbo, stay away from WOT and you keep up engine vacuum therefore your motor sees no boost. They are alot more streetable, lots of power there when you want it and calm as a kitten the rest of the time. Ya a big roots blower looks cool, but I'll take my $2000 S-trim and absolutely rape a $5000 Kenne Bell positive displacement blower. Just something to think about. If I was building a '32 Ford chromed out show car then sure I could see a huge blower sittin up there, but in my 10 second street car, its just not gonna happen. Thats my opinion though. I just dont see that a roots or twin screw blower are justified for more of a daily use than a centri blower or turbo on cost or reliability.
