Little side note about T/S superchargers...unlike the Roots type supercharger the twin-screw exhibits internal compression..

it has a much more complex rotor design... as you can see here.

very nice...here is some pics of the C-2 and cut out and comparisson of the F4 over the F1

o god thats sexy

 

twinscrews sound awesome. get it.. get it now

 

i vote for twin screw.

BTW
the f series blowers are effin massive

 

PLLLEASe resiez those pics.. theyr'e too big for me and my resolution is 1600-1200 ... procharger looks like pure sex. makes me drool and wish i had money even more

 

that is a Procharger F1r

it's a mercury capri.

 

Damnnnn!

 

untill you see one in person. you can not actually get a feel for how big they are

 

F1R FTW! the F1 and F3 are nasty man!

 

At my old work, we dyno'd a 540 big block chevy with a F3R procharger... ****** made 2300 hp!!!!111!1!1!!!oneone!!one!!11

Then a couple months later we dyno'd another 540 BBC, but with an unintercooled F1 at 10 psi. Made 1358 hp on 91 octane

 

Centrifugal is more efficient than Twin Screw

 

Yeah, but doesn't hardly make boost at lower RPM, and has no WOT whine. NOT COOL Supercharger MUST have a whine, its in the rule book

 

I agree with you...I'd get a KB before a Procharger

 

i posted some videos on the procharger during WOT

 

i dont even doubt it...the cfm is unreal so that is why we are worried the 2.95 pulley is to small might be flowing to much cfm :O
