The downs of a SC
From this thead https://www.s2ki.com/forums/index.php?showtopic=454055 the second posted said,
" Are you dead set on a supercharger or would you consider a turbo? The only superchargers available for the car right now are centrifugal setups - I'm sure you know the ups and downs of that type of blower on a low displacement engine."
Now I"m quite certain on getting a supercharger, as I had a turbo charge car before and I want something different. The most i'll go on the supercharger will be 7psi to get a good 350hp. Anyways, I wanted to know what the downs are in that type of blower on our engines. I mean I done my research on it and I couldn't really find anything wrong with it. That or I can't search right. Oh, I'll be going with the Comptech supercharger. Thanks guys

That was my post 
You're not going to get 350hp with only 7 psi. You're going to need around 10 pounds of boost, so you'll need larger injectors and some type of EMS is going to be needed to tune it. This is going to run you another 2 grand. 7psi will only net you 300 +/-10 hp.
When I said that there was a downside, I wasn't referring to anything harming your car. I was talking about the downside to a centrifugal blower in general. They are mainly for high displacement motors that make a lot of low end torque and power yet run out of steam up top in each gear (like a Mustang for example). The centrifugal blower makes power as RPMS climb and helps it make more power up top where it needs it. The centrifugal blower on our car is just like the motor is set up: not much torque or power in the low/midrange yet makes a lot once VTEC hits.
The poster in that thread has been riding bikes a long time, and I was just thinking that he may not be very happy with a supercharger setup possibly. This is because yes, it makes a high peak power, but it's not very usable for day to day driving like a turbo would be.

The only con is the fact that it can only create power in the higher RPM's as opposed to lower and mid-range which a turbo can be configured to deliver.
I also think that the Vortech and Comptech kits are somwhat less efficient in creating power compared to whats available for other cars but thats a different story.

If you were to simply bolt on a CTSC then the boost isnt there untill high rpms, but with an AEM EMS you can lower the RPM at witch VTEC engauges creating boost sooner, (and more fun!).

Who the hell talks about crank hp?
It's not measured when you dyno, and if someone asks you how much hp you have and you say 350, they'd think you were full of it. People talk about what's made at the wheels - it's kinda the standard

cool thanks everyone...
Yeah, 7psi isn't that much of a gain, but a good solid 350hp (300whp give or take a few whp) would be a awesome start. But for now, i'll keep it stock with just TP and exhaust.
I'll wait for AEM's new piggy back system to come out before I go higher PSI so I won't have pay that AEM EMS price hehe...
