supercharger or turbo
 

hey guys i have a 09 si but im not sure which one will be more beneficial to put into my car between a supercharger or turbo? :dunno: pros and cons of each its been a hard decision.. any advice would be appreciated

turbo

i was thinking that also but theres so much bullshit that comes along with it...

turbo has lag, supercharger has instant power. if u want big power gains ur going to have to to go turbo n build the internals. but other that that, i depends on what kind of a sound you prefer.

superchargers make a whine noise, while turbos have a spool sound when it spools up

so, you gotta ask yourself first, what kind of bullshit are you refering to?

with a SC, it takes power to make power. turbo's use exhaust gases, you're only going to lag if you don't use the right set up.

sound should not be a factor in deciding weather you want turbo or SC.

whaat? it sure is.. every 1 has their own preference spool > whine

N/A is best

Keep it stock and build the internals, then on you can decide in the future which one to get.

Boost is the way to go. Obviously people will have their own preferences. It all depends what your power goals are. I have a STOCK gsr B18c1 with an 18g bolt-on greddy kit. on 8-9 psi the thing was at 289 WHP and ran beautifully until i sold the car. My buddy had a 2001 gsr with a jackson racing supercharger kit upgraded pulley so he can run more boost and i still raped him all the time.

Ps. a little turbo lag can help with you launch when drag racing unlike a supercharger where u have instant power.
Its all about the correct sizing.

NA is best.... but Boosted is better.

Either is a good option... but it all depends on how much you want to spend.
just a little = Super, maybe a lot = Turbo

Why so?... Supercharging, with a trusted manufacturer is easier to deal with, and less maintenance.
If you go super, keep with a centrifugal design like vortech or procharger. Better suited for high revving, top end power. Work very well with stock motors

Turbo's are great too, and yes a well thought out setup, will have little to no lag, if mid-range power is what your looking for....
If chasing top-end power, better welcome some turbo lag.
& looking for more than 11 psi, gonna have to crack open the motor and reinforce everything.
