You can assume it is higher than the actual work you are outputting to the crankshaft because some parts rob power (alternator & water pump). Therefore, you could probably estimate that the stock...

For you metrically challenged (like me), that's about 588 CFM (1000 m^3/h).
Can anyone confirm the following radiator temperature drop data? We saw a 9.6?F (5.3?C) average drop when coolant was flowing through the radiator. The peak temperature drop while coolant was...
Our rules state that about 66 mph is the top speed seen in the endurance event.
We got our Perma-Cool 1650 CFM fan in today. The surprising part is that it covers 80% of our radiator with no shroud. Too bad it weighs 4 lbs.
Perhaps a copper radiator would not be much better. According to some websites, typically the tubes are made of brass, but the fins are made of copper. To join the two together, a lead solder is...
Switching to a copper/brass radiator may be an option, but extensive testing would have to be done to show that it could cool the same amount as the aluminum radiator. For a good article about a...

Shroud or no shroud?
Perma-Cool states,"All Perma-Cool electric fans are designed to be installed directly to the radiator core, close enough to not need a shroud." They also write, "A general...

Our water pump flow rate needs to be tested again. Our team did not test it right 2 years ago, so they did not get accurate results. I believe they tested it with no thermostat in the engine. Can...
Jonno, you're right. We did our testing with no load on the engine, and our flow meter had too high of a pressure head loss to be accurate.
Aluminum tubing saves about 1 pound of weight per foot compared to rubber hose.
Our testing used thermocouples in the water flow right before the exchanger and directly after the exchanger. We tested a set of dual exchangers from White Oak Radiator, and we tested a dual-pass...
Through our worthless testing, we saw a max heat dissipation of 72 kW through a single heat exchanger on a CBR600 F4i engine. This is useless because the engine was under no load.
