Cam Gears + Pullies

[thermal]

No significant gains on those as a bolt on. The adjustable cam gears will benefit you later when you get your turbo set-up dyno tuned. I never really believed about the significance of lighter pulleys except for weight reduction. The factor of inertia will be affected but for a slightly modified car will not do crap. You will have less rotating mass but that's about it. Although depending on what turbo set-up you plan to do later, it can be detrimental to your goal.......
