upside downside pros cons prices....... for an underdrive pulley thanx.

 

I recently completed my cam swap and added an ASP underdrive pulley since the stock pulley has to come off anyways. Upon test driving I immediately noticed how much more responsive the engine was to throttle and how much faster it winds through the rpms! I can't really say if it's a big SOTP feeling b/c I installed a cam at the same time. Most agee that it's worth 5+ rwhp.

Costs about $200 so not really chump change. Also most places are backordered big time!
