I really don't think they are needed unless your car is revving fairly high most of the time

 

[HRT 666]

Cost Is around $300

Benifits????

My personal opinion is they are not worth it unless you are fitting a cam. The power difference you will not notice only about 2-3 rwkw.

I only fitted one cause i dont trust the stock one

Why do they make more of a difference with a cam?

Cause stock engines wont rev to 7,000rpm where the accesories take power out of the engine due to higher rpm and loading.
As accesories do a much higher RPM due to pulley gearing.

ahh fair enough.
So basically no point on a road car at all then. Because at 7000rpm in first gear you're going to fast anyway...

No speed limits on a track.
