We could do a refrigerant system, if the compressor does not detonate at the high engine speeds. IT would be easy to cool below the ambient if we could accept the high engine loads and enormous HIGH STATIC pressure condenser we would need. Our auto AC coil is good for about 1 ton more or less, and that is only 12,000 BTU per hour, which is at least 1/4th of what
we want - need.

I need to establish the baseline performance levels of what we got, so as to quantify and measure any improvement (s ). This way I can determine if the gains are worth the cost and efforts involved and do a thoughtful trade off.
