When the ambient (outside temperature) is cold (30F-50F), the 2nd cam kicks in STRONG with a definite kick. When the temperature outside is 50F+ the 2nd cam "kick" is less noticeable. If it's a warm or hot day (80F+) outside the 2nd cam is hardly felt at all!:shrug:

All cases the engine has been warmed up properly....

Have you noticed that with your N/A Elise?:TADTS

cooler temps = more dense air = better performance.
( ask me how I know rotfl ) ( it's an aircraft thing too )

Guys riding two strokes or driving turbo cars know this one as well!

I don't know man...you should be able to feel the kick from the second cam in all temperature settings :confused:

The A/C is almost useless for cooling the passengers, so I'm going to duct the cold air from the A/C to the inlet where the snorkle was so cold air will be forced through the air filter.

Kind of a poor man's supercharger!:nanner:

kestral74: Should we share the patent?:confused:

how about a dry ice intake ? or better yet, a Liquid Hydrogen container that intake air flows over ??

You're kidding, right? Have you ever read about perpetual motion machines? They don't work. Performance gain from cooling your air with the AC will be minimal compared to the performance loss from running the AC in the first place.

my a/c didn't work worth a hoot til i closed off the inlets behind the front center grille.
it also fixed the heater.
run the heat and the a/c in recirc.

Presuming the evap core would get nice and cold during a minute of cruising down the highway, and then also presuming the compressor is turned off under full-throttle conditions, you could actually see benefits from using the AC to cool the engine's intake charge. It would be short lived each time you floored the throttle, but it would work.

Charlie, when its ~40 or below, my car seems to pull timing, and engage the cold running rev limiter. Now, Im not flogging the car until its 180degrees, so unless the sensor is reading wrong, the car should be at the appropriate temperature.

cept the ac turns off when your floor it.
Yes, but the evap coil would still be cold for a bit. Would be useful for short row through a couple of gears perhaps.
