its recommended NOT to use a CAI on a supercharger. its said to be to much air for the engine. i know ford has outright said not to use one on the roush and cobras because of the supercharger.

With a jrsc is it usually best to leave the stock airbox on or will a short ram be better mated to the supercharger? I'm curious about this too.

my buddy just got a JRSC on his ZX3 yea different model however same concept....WARNING!!! DO NOT keep aftermarket intake on because your car will have WAY too much air and it will run lean instead of rich and potential blow or damage to the engine (SAYS MCNEWS AUTOMOTIVE) Also you may want to upgrade to 30-35lb. fuel injectors because youll run outta fuel around 5k rpm. Just a suggestion if u want the JRSC do it right and tune it before you run it at ALL...i saw a post where someone was waiting for there car to be tuned before they dogged on it and [:)][:)][:)][:)][:)][:)]** wiat til its tuned to even drive it. He unfortunately experience headgasket failure. Probably because he ran lean. So please if you get the JRSC (highly recommended i saw a 51WHP increase in the ZX3...

(here visit his post http://www.focusfanatics.com/forum/s...threadid=47202 and click his video link...his ZX3 spanked me...im the one driving the SVT we ran 15.10 him--hes capable of mid-low 14's he just took it easy cuz he just got it--and 15.8 me--bone stock)

...but if u get it do it right and dont take ANY cheap way out or shortcuts because nothing is worth a blown engine, especially one that is very nicely built. so visit that link and then click his video link @ putfile and if u have an y specific ?'s that i havent answered hed be more than happy to answer them his name is shawn!

Hope that helped
~Chris

You should be able to tune around the extra air from a CAI. With the stock TB, you won't be getting any more air in the engine anyway, that is the bottleneck. More air into the blower = more power but you have to make sure your tune is in good shape to make sure the A/F stays in a safe range. Larger fuel injectors and/or fuel pump should allow the tune to stay safe with increased airflow.

/\ dont listen to him. hes going to cause you to destroy your engine. you would have to bump up the amount of fuel the injectors are putting in the car to equal it out, and your exhaust valves would have to be bored to take the increased amount of exhaust. and tuning a CAI would be dulling it down, so in the end it would be doing nothing.

Ok, so no CAI, looks like I'll be selling that in a few short weeks (keep a look out) So what of the Throttle Body and Pullys? Will those work with the JRSC?

Pulleys will work, but it will underdrive the supercharger = less boost (less power). You would need a smaller pulley on the supercharger to get back to stock boost levels. I don't see why the throttle body wouldn't work.
