I designed and built a solution to the heat bog

I tought the answer was 42!
(hitch hikers guide to the galaxy
)I'm also interested in the product. DieselPilot, how is it working out for you so far?
Today we had a very nice and succesfull meeting in Holland where we had a few owners with different kinds of air intake systems.
Since we were all driving the same stretch and idling under identical circumstances while lined up for the pictures, we had a good opportunity to check the intake air temperatures of several systems.
We used regular OBD scan tools to check the real-time air intake temperature as registered by the air intake temperature sensor which is fitted as standard to the car. This temperature is available on the OBD port.
We tested the following:
(Temperatures are stated in degrees celsius in idling condition and higher engine speed conditions)
Stock airbox 72 - 70
Stock airbox with the lid removed 76 - 72
CAI with filter element in the engine compartment 67 - 62
CAI with filter element outside the engine compartment 64 - 57
PRM with aluminum pipes and enclosed K&N filter 76 - 72
Chrome metal L-shaped pipe with open cone filter at the end 64 - 56
The biggest shocker was the plain non-cold air intake with bare filter, for some reason it retained the least amount of heat.
So my observation and uneducated conclusion is that at which location the air is actually extracted is secondary to the whole heat bog situation. It appears to more a problem of mass and the retention of heat in filter, filter housing and duct work.
I would be extremely interested in seeing a similar back to back test, or rather a two car test, one with the new device installed and one without.
Please understand I'm not trying to make a specific point or take a position on 'the invention'. I just wanted to share my observations! I thought it was amazingly amazing!

Take care,

i would think that if they were done one at a time that there was time for vahicles to cool. even a few minutes could mean a few degrees.

so were all these cars tested simultaneously or one after the other?

I see your point, but the whole deal about the heat bog is that it occurs during idling after driving and the temperature under the hood does not decrease, but it increases!



(to those who figured out The Answer. RIP Douglas Adams, thanks for all the fish... and insight)
very nice
