The reason Im not a fan of Vortech is....because Ive driven it and dont like it!
Honestly, its a decent system. But for the money, you may as well go turbo. For the lag, you may as well go turbo. For the potential, you SHOULD go turbo.
The Vortech is a decent system, and would be preferable in many cases if there was no such thing as a turbocharger. It just isnt that spectacular with the choices and technology available now.
BTW, I dont believe anything magazines test. I remember a while back SCC ran an Si with a prototype HKS kit and ran low-mid 15's if memory serves. I dont care if you're on 19's with an iron sub box in the trunk, thats pathetic!
