Im sure this has been asked a thousand times but Im kinda curious about the hp gains from going from a stock SC pulley to the 15% pulley. Is this a significant power gain or should I consider the 17%. Im not trying to break any records, just want a good jump in power but a safe one.

 

Yes, been asked many times! 15% is considered the "safest" jump from stock and YES there's a very noticeable improvement in acceleration!

 

Try making use of the SEARCH function at the top r/h side of the page~~~it WORKS well ! OBEY
