First of all Brad and Simon are stand up guys and Evosport is good company.....

I just think there are some questions that people have on this specific product. In my experience with the pulleys on the M6:
  • I took issue with the pricing - a pulley on a BMW is 4-5X price of a domestic - but this is just personal and non-relevant opinion to performance
  • I just didn't see real world performance with my pulleys but I did see slightly higher oil temps
I had the pulleys on my M6 last year when I went to Mosport in my M6. I have gone again this year, with the stock pulleys. There is a long uphill straight at Mosport. There was no appreciable difference in speeds at the end of the straight. With the pulleys, the car did run hotter.

I have no doubt that the dynos show these results. And my buttt dyno may be miscalibrated. But can you corroberate with some trap speeds at the dragstrip with all things being equal except the pulleys?

ND54, props.....go visit!
