Talking How fast does the water heat up in the I/C?
I have put together a video of my first 1/4 mile run from the recent MIR races to show the operation of my I/C and larger " Super cooler " H/E. This is to be as close to real world conditions as I can get it. Run number 1 is shown with my car on about 70+ degree day at 10:40 AM.

The temp monitior on the left shows the temperature difference of the water entering and leaving the heat exchanger. Higher readings indicate the number of degrees of cooling the H/E is producing and allows you to see rate of change. It is interesting to note the speed with which it changes up and down.

The temp monitor on the right shows the water temp entering the H/E which is the same water temperature leaving the I/C. It is interesting to note that the water immediatley changes with load conditions. When I just punched it on the water, and on the return lane you can also see the rapid rise in temperature of the coolant.

The water in my heat exchanger system is moving at 4 gallons per minute, much faster than the stock exchange which flows less that 2 GPM. This is due to less restriction in the H/E core. Faster circulation promotes better cooling by scrubbing the I/C with cooler water and pushing the hotter water into the heat exchanger for cooling. This cooler has the greatest surface possible for the car and thus really assists in cooling the intake mixture to the cyclinders.

Monitoring of my H/E operation with a camera has been the best way I have to record multiple reading while driving. The small gauge on the left is monitoring the vacuum in my intake manifold( just before the throttle body). Straight up on the gauge is about -5 inches of water (vacuum), which is much better than the previous CAI when it was at -30 inches of water(vacuum).

The gauge on the right is a 15 psig gauge monitoring the boost AT the air intake manifold. The next mark is 16# which I seem to be hitting at full rpm edge, though my dyno testing showed 17#. My gauges and Pod installation has taken a bit of a back seat to testing, due to the approaching colder weather.

Hope this is interesting and possibly informative on several levels.

ENJOY, W DY

Remember these are heat engines, cooling makes more power

P.S. Watch in high quality to see gauges, Sorry for reflections.......
