Anyone run track events with a set of underdrive pulleys on? I saw that UUC is coming out with some for the e36, Rogue just released theirs, and, while tempting, am slightly concerned about the engine getting sufficient coolant flow. Looking for the warm fuzzies to spend some $$$ on a worthwhile mod.

Every World Challenge BMW Team I've observed on the Touring Car grid runs underdrive pullies. We also run them on our M3, which runs laps times simliar to a World Challenge GT car. If it works for them, it should definitely work for you on a track day.

I'm thinking they *might* run their cars a little harder than I'm going to push my 328. Thanks for the feedback.
