Yes, your WP should be overdriven. I use a flowkooler n my water pump is o/d. Again, in 125° mine works great. In 90°, I can barely get 196 at idle w 180 stat.My crank pulley diameter and water pump pulley diameter are the same. I've just ordered a Flowkooler pump. I'm wondering if I should try to locate a smaller diameter water pump pulley to overdrive it a little, to assist in cooling when at idle, which is where I'm having the issue. Both pulleys measure out at 6.75" as best as I can tell. Maybe the Flowkooler pump alone will do the job.
