what are the pros and cons of each???

cyntrifical supercharger and roots style?

[AtlanticBlue99]

roots usually cheaper, low end power
centri high end power, better for drag racing since you are in top of powerband anyhow.

[itschristorres8]

roots will better off the line
centri isnt as fast off the line but it'll make up for it at top end. roots and top end dont impress me to much...=/ thats why turbo usually eats them up

[KaZpeR]

say a turbo sti pulls next to me then which one would own him since the last time i raced him my car was stock i want somethin that will make him feel like its a kick in the nuts

[itschristorres8]

well what do you havE?! v6? GT? cobra?
they have i think near 300hp
any s/c on a gt will beat it. as for v6 i'd suggest centri with bolt on's

[KaZpeR]

ya i got a gt 05 with cai, tune, exhaust, and 4.10 gears but i dont know his car is F**kIN fast he must have more done to it then what he told me

but i dont know i like the look of the roots more looks less cluttered but you say performance is better with the centri so i dont know

[itschristorres8]

i used to think the same but centri is what im goin for.....well if u get full bolt ons on ur GT, ported heads and some cams then throw a KENNE BELL s/c!!! u'll be in the 400's id say for sure. and destroy that sti. kenne bell makes i think 2.6 and even maybe 3.0 size pulley for 05+ GT's get those. Kenne bell makes a bad ass s/c

somone on the site has an 05 or 06 kb charged GT. i think hes in the 400 range not sure.

[3.8Coastie]

yeah kenne belle does have some bad ass chargers... i wish they made one for a 96 3.8

What did he say he has done to it? What does it pull in the 1/4? I know that they do run 300hp stock also you got to factor in that they are AWD which mean oee the line, if he knows how to launch it he will jump out on you anywhere from your front bumper being at his back bumper to a full carlength in between. I would be able to give you and idea of what he has if you tell me what he told you he had done and you give specifics and your race against him and or 1/4 mile time.

true if you race him i'd do it from a small roll, maybe 15+

[KaZpeR]

i ran him from a roll at 35 40 in second gear and he just pulled away but thats when my car was bone stock

he said he was running 11's but i didnt believe him but when i ran him i can see how it could be true

[MSO]

yea those imprezas kick ass

300lbs of torque stock, lighter (i believe) than the new 'Stangs too

[itschristorres8]

11's..he has to have a good number of mods then or some

right you are
Curb weight (manual transmission)
3,351 lbs.

There are so many different varieties of each a compare and contrast is hard. Alot of people think that roots is "old school" and centrifgul chargers make more power.......tell that to my buddy who has a 66 Chevy II with a 2500 horsepower big block with a 14-71 roots huffer. Each version has low end and high end units. For EFI cars a centrifigul is the best bang for the buck and will make awesome horsepower.

[MSO]

then again, imprezas come stock wit a turbo

so he got mods on u right from the get-go

[Drgnracin72]

you cant count a car that comes stock with a turbo as a mod. if the car is built to only run a turbo, you cant hold that against the car. as for what chris said, about the diff pulley sizes. your confused. they has a positive displacement blower, and they are like a 2.4, 2.6, and 3.0 those arent the pulley sizes. pulleies on different cars, are going to make different boost. throw on a novi 2200 and youll never outgrow it. its a badass blower. oh and the positive displacement blowers for the mod motors arent roots blowers, they are twin screw. they might look similiar but the innards are totaly nd compltely differnet

with that much gear, get the procharger kit. with the 4:10 final ratio of the blower, and the 4:10 gears in the rear, just get some drag radials and eat him alive! the procharger cars have a nice midrang and tomp end charge. other then from idle to 2500rpm, the procharger will walk a KB car. and its cheaper too.

[Drgnracin72]

novi, novi, novi, novi. if your going centri, you cant beat the novi 2000. youll never outgrow it and has the potential to run in the 8 sec range

WTF? You can't be serious.... What does the step up ratio of the blower have to do with the rear axle gearing?
