It has been around for awhile. Never tried one!
I run a bigger radiator and a standard size crank pulley. Don't have any cooling problems, yet.

thanks for reply, my problem is that we have replaced the original radiator with a larger one, made it tripple flow but on our first dyno run we made 940hp. if we had to run a consecutive run the temperature would be way to high. I would have to let it cool down. car is a gto pontiac engine is a 403 ci warhawk block with et ls7 heads we used the ls1 pump that i previously had.A vortec ysi supercharger with custom intercooler was used still at tuning stage with belt slipping issues, ill post dyno run . my first priority is cooling issues any thoughts.

Evans pump Use the Evans pump with correct size pulley for your application. Leave the stat out. The pump will flow enough coolant for a thousand plus horsepower.
The Evans pump is designed for increased flow but also more equal bank to bank flow than the stock pumps. We had tests run of these pumps (Evans, stock LS1, Meziere electric) during development of the Darton MID sleeves for the LS engines. The stock pump flow to the right bank decreases noticeably past 5,500 rpm.
