I love my Meziere.
I bought it through INTENSE, and got the Casper's wiring kit for it so I didn't have to cut and splice factory wires. Plug and play simple install.
I can attest as well, matching this with a manual high speed fan switch allows for extra quick cool downs at the track.
If you have a drilled t-stat even better results can be had.
In the pits, or staging lanes, turn the key to RUN, and turn your fans on high, and the pump will circulate the coolant with the engine off, and as it passes through the radiator the fans do their part. The d
rilled t-stat will insure that the coolant will still flow even if it gets cold enough to close the t-stat.
Though it does help to have a good power system.
My set up is a stock alternator (but has been rebuilt and polished by me) and a Optima Red Top battery. No alternator hot wire kit, or high out put voltage crap on my car.
I like my Meziere so much on my GP, I am going to buy one for my LT1 motor I'm stuffing into my Sonoma pick up.
