FIT/JAZZ Supercharging Open Discussion
OK you all need a place to discuss supercharging... well here is is.
Please keep the discussion to GENERIC supercharging discuss for FITS/JAZZ only. Please do not mentions SPECIFIC brand names of setups unless YOU HAVE ONE INSTALLED ON YOUR OWN FIT. We are not interested in what you did on your other cars so keep it FIT/Jazz specific.
But feel free to talk about all TYPES of superchargers not just brand specific. Have fun

in generic response i would rather super charge this car than turbo it , but i wont mess with this car until someone can get decent head work going , like upping the compression a lil , then super charging would be killer
i think there was someone onthe boards that took a ride in the jackson fit at peak boost . . sounds fun

that cookie cutter thing will do nothing for your perfomance in any other car I've heard of. I don't think the fit will be any different. For either Turbo or Supercharging, if you keep the boost low enough, and the tune is good, you should be okay, but positive displacement superchargers, like the roots type give a constant boost while engaged, which makes for a simpler tune.

All supercharged / turbocharged auto's have an intercooler of some kind. Some may be in clear view while others are in the engine bay area. Reason being the intercooloer disipates heat it's receiving from the outside temp, keeping your turbo/sc running at cooler temps.
COOLER TEMPS = MORE POWER.

alot of the older SC mustangs and other cars didnt use stock intercoolers. The Rotrex SC doesnt create alot of heat like turbos do, therefore not necessary. Most turbos genberate alot of heat so even for low boost apps a small intercooler is used.

it's beneficial for turbocharged vehicles to have intercoolers, even smaller ones, like JDMchris said. but they aren't always present. for example, a stage 1 turbo kit might not include an intercooler. adding an intercooler then ups the power increase even more.

Comptech is in a mess as a company. Their R&D is good, but their business management was lacking and the company almost imploded. They recently got bought out and under new management, currently trying to get everything straightened out and R&D back up. JR is definitely reaping the business in Honda blowers.
Unless Redshift finally comes thru with their twin-screw setup for a LOT of different Hondas, JR is the dominator right now.

Forced induction (turbo or SC) does not require an intercooler. However, not using an intercooler is leaving cheap power (and efficiency) on the table. Almost all of the heat generated is a function of compression of air, not the actual device... see Boyle's Law... Boyle's law - Wikipedia, the free encyclopedia
Practically all modern turbo setups have IC's because they tend to have very high boost pressures (my VW 1.8t would spike to 22+psi), so they generate a LOT of heat. SC's are generally much lower pressure, so they can get by w/o an IC.
The whole point of FI is to get more air into the engine so you can burn more gas. By not using an IC, your intake temp will be higher, density will be lower, less air, so less power. (refer back to Boyle's law).
The downside to an IC is (depending on how everything is arranged under the hood) a much longer intake path, which translates into more "lag" when you hit the throttle.
