[Ice] Cold Air Intake

I just thought of this the other day...since countless people believe in cold air intakes

say if you re-routed the A/C fins for your cabin to pass through the intake manifold first...then you can probably lower the temperature of the air in there by 30 degrees...

just an idea. but somebody tell me if this could work or not

So you think that the HP increase is going to be more than the draw from the AC?

No...

Also we have multiple valves which are effectively a "vtec" system

Unless you actually meant Vtech

You're better off building a "pocket" for dry ice to sit in the intake tubing pre-MAF. This is going to lean you out, perhaps too much for the ecm to compensate. Nevertheless, I wouldn't reccomend it.

The use of the A/C is redundant because it draws power from the engine to turn the compressor. So....no, it's not worth it.

Even still, the gain is going to be so small, and vary greatly.

MMmmm interesting .. I've seen such things for intercoolers

So dry ice is what? -110F
The IAT goes to -40F

I wonder if it would actually chill the air past that -40f

I say the OP should try it

Then why is my IAT average about 10 to 15 degrees cooler with the AEM CAI with the same ambient air temp? Curious, you know.. for science.

Dry ice in the intake tubing? CO2 injection? That'll burn real good.

How about running the starter motor full time for extra hp? The extra power will produce extra electricity from the alternator, which will produce extra current for the starter motor, which will produce more electricity which will produce more power ==> lightspeed with a billion mpgs!

AC to cool intake air to get more hp makes just as much sense.

I notice a difference in the amount of boost I can make, in the winter.
When I was NA my butt dyno did say +1 for cold air ... but thats the butt lol

Because it doesn't have a box to cook your IAT's at idle. I doubt you measured much, if any difference at all, at cruise.

Sorry to spoil your secret project, but I think pointing all the stereo speakers backwards will be a more effective "boost".

I really shouldn't be making fun, but most of the last effective original ideas to improve the IC engine probably were had before 1950. Many had to wait for better electonics, materials, and manufacturing methods to implement, others remain, but none so far violate the laws of thermodynamics.

Fiddling can be fun though. Good examples are found on ecomodder.com

You can also put black nasty over the exhaust pipes to stop the tiny horses from escaping.

Putting hay into the intake feeds the horses so each horse is worth 1.1 horse power giving you 10% boost in power.

You know that a horse actually has around 15horsepower right?

I did not know that. I knew a horse has 10 man power but not 15 horse power, it seems a bit silly.

I have an AEM CAI as well, I'm not doubting it works...

It sounded as if he didn't believe in a CAI as this thread seems as a troll thread to me, I was saying MAZDA put one in our car.
