If Euro-Rev wants to approach me and install them on my car for my next event with the Racer Factory, I will evaluate them. Here's a challenge for Euro-Rev... I'll bring my car to their facility have them installed... Run the car at Spring Mountain Raceway on October 22 & 23... If the underdrive pulleys prove to make a noticeable difference in the car, I will purchase them after the event... If not, I will give them back...

Let's see if they put their money where their mouth is...
