Underdrive pulley 10-HP gain.
Has anyone installed the 25% underdrive pulley on there car yet,if so have you felt any noticable HP gains.I already have a set of shorties on the car and figured the pulley and CAI would be a good way to go. The pulley claims to add 10HP.

Did you notice an increase in coolant temp at idle?

I am working with ADM Performance on a replacement pulley for my L99. Hoping to do it this week too. Whenever I get it done though, I will post the dyno graph *and* the track results, which is what really matters to me.

I have baselined, installed TSP pulley kit, dyno tested, and removed pulled kit for redyno. The pulley added a confirmed 8rwhp....
