Underdrive pulleys and Cooling on a race track?
Looking to replace harmonic balancer. It's got a wobble so I know I gotta do it soon. Looking at doing a Underdrive pulley but this car is 100% a track car. Bit Concerned about turning the waterpump 25% or 10% slower. Anyone Race with these things?

I would think a little under drive on the WP might actually be a good thing for road course use. I swear I remember reading some posts about the water pump and RPM it starts to cavitate...but I can't recall off hand. All that said, I ended up getting an ATI 10 UD for my car when I was doing road course stuff. I had a dewitts radiator and even in the heat here in the south temps never went above 200F, so all in all in seemed to be working well.
I have it off the car now and was going to be selling it soon... if you are interested please PM me, otherwise look for it in the for sale section soon.

I bought the car already modded with Radiator and Oil cooler So I'm un sure the brand. But I drove the car prior to the radiator and oil cooler and I could see water temps of 230 and oil temps over 300 in a lap and a half of sebring in june. The previous owner added the cooling, I haven't had it to sebring in the summer but I ran Road Atlanta in August with it and I saw 218-220 water temp and 270 oil temps in 1 or 2 hot laps. Thats why I was concerned as I feel like the car is right on the edge of staying cool as it sits.
