Noob in need of advice-Rotrex Supercharger
 

Hello fellow Miata Enthusiast!

After a long search and driving my husband crazy with questions, I've decided to reach out :) I bought my '97 about a year ago to try out Autocross, but life got in the way and I never got the chance. I would, however, like to know more about my car. I bought it from a gentleman who put all the extra goodies on it, but I really am not sure what most of it means. My biggest question I guess at this point is about the supercharger on it. I know it was professionally installed by a shop, I know it's a Kraftwerks Rotrex. I was told it SHOULD be the C30-74, but I have no idea how to confirm that. I looked all over the part and couldn't find any markings and the installation/maintenance paperwork that came with it only give me 3 options, but doesn't specify which it is (booklet is for the C15, C30, and C38). Can anyone tell me if there is a way to verify the size of the supercharger? Many thanks!

No idea, but I am interested in your name. Do you build tracks, or ride them?

The Kraftwerks kits came with the C30.

I used to ride mostly off-road/trails etc, but I got off two-wheels a little while ago. It's actually my husband's screen name, he has been racing/riding since he was 4 or 5 years old. He rode tracks all over Florida and Oregon, but we are in the process of trying to build our own track. :)

Thank you Concealer404!!

Rotrex's website has physical dimensions in their datasheets if you want to confirm if it's a C30-74.
