Yeah I'll post up the results next week when the pulley comes in. I sure hope this works, I've fought cooling problems since day one and have never been able to sit in traffic for longer than 10-15 minutes without overheating on a 100+ degree day. As long as it's running down the road it's ok, but if there's no airflow then I really get worried. I've never had a lot of room, hence the single 16" fan, but enough is enough. I thought about the taurus fan but it doesn't fit the core as well as the Mark Viii fan, 18x16 vs 22x19. Both are 2 speed and supposedly use the same motor. We'll see though, after testing the fan on my workbench I must say I'm pretty confident. This think moves a ton of air, and it will be nice knowing that every inch of the core will have air flowing through it at all times.
