I've been looking at going forced induction on my 08 gt. Only racing is road course stuff with the local club just for fun. Anyway I'm on a budget and was looking at a used Roush M90 kit when I came across the rotrex. Spoke with the guys at forced air and they told me that the stage 2 would make about 420 whp and more torqe and power then the m90 in any part of the power band even off idle. Straight forward install in 4-6 hours. $4400 - $4800 dollars for the complete kit. I checked around the web and can't come up with too much. A dyno pull and some racing on youtube. I'm looking for a fun street car,,,,not too worried about top end power and I'm on a budget. I can pick up used Roush M90's for around $2500.

I've never heard of this brand before...I'd be more apt to stick with one of the more well-known ones. You're more likely to find a tuner who can work with the more common brands easier.
 
Saw a guy running the track last summer with one on what was otherwas a stock early-90's 3.1L Chevy Cavalier. Car went low-8's in the 1/8 spinning the front tires all the way down the track.

....so yeah...they work. :nice:
 
I got one, its alright. If you buy one new, find out which head unit it is, you want the c38-91, the others are ok too, but might as well go for the biggest one...
