Limited Edition 8v Supercharger Kits Available
Big props to Neal for taking the time to share AND EXPLAIN this great
opportunity with the list! If I hadn't just plunked down the same kinda ca$h
for a turbo setup, I'd definitely be in on this.
Peter Tong is by far the most knowledgable S/C guy I've come across on the
Vortex. He's also managed to wring just about every ounce of tuning potential
from the CIS system for boost applications. The best part about it is that
he's helpful and open with his knowledge.
As Neal mentioned this is probably the best (and possibly last) opportunity to
pick up some great equipment (without paying Bahnbrenner-type markup!).
