I'm wondering why a few people in some circles claim the Vortech #'s are underwhelming, but yet had no comments on the Rotrex results.
Sorry Drew I was not aware that it was that big of a difference.
It is hard to deny how good the vortech blower really is. Considering all of the performance records on the E9X M3 are dominated by Vortech powered kits I think the results speak for themselves.
