STILLEN 370Z Underdrive Pulleys Released

Bster

Thanks for your short yet detailed explanation! Appreciated it.

Yes I agree I could have googled it, but coming from a consumer's point of view, I could not find any explanation from Stillen's webpage or from their initial first post on this thread. Which seems odd because how could a business can sell a product without providing even a small explanation on what the product does is beyond my "business imagination". I suppose the vendor expects us to google for it.

I come from a pretty modified Mini Cooper S background so I do have some understanding of what an under sized pulley will do for the Supercharger. And when I bought the undersized pulley for the Eaton supercharger, there was an explanation as to what the pulley does in terms of benefit. You know... smaller pulley = supercharger spins faster = more horse power to wheels = happy motoring days!

Anyways, after reading the wikipedia link, I have a better understanding of the pulley now and this product is probably better for colder climates not not for my equatorial country where I need the air-conditioning power! That being said, the stock sized pulley will be be the one for future consideration.
