Spinning the water pump faster?

Okay guys,

I've been trying to find this out for a long time. My car will run at about 180 degrees when moving but when I get stuck in traffic on a hot day I just can't keep it cool. I've got every cooling device known to man kind. High flow water pump, seven blade steel fan, aluminum radiator with shroud, electric pusher fan, engine oil cooler/transmission cooler combo and I've sealed the fiberglass hood to the rad support (which made a difference). The only thing else that think of to do is to spin the pump faster but try as I might I just cant figure out what the sizes are of the non A/C alternator and crank pulleys are versus the A/C pulleys. I think that someone might make a aftermarket pulley for increased flow but I'm not sure. Have any of you guys tried spinning the pump faster and did it work for you?

Thanks For Your Help!
