Race cars normally run air to air so I was wondering if there was more to it.
I've read the regs and it occured to me that an a/c compressor could be used to cool the charge cooler water (in combination with a heat exchanger).
The compressor could be powered either of the crank and clutched in under decel/low load or it could be completely electric and run off the mgu-h/k excess in which case the compressor could run all the time.
It would obviously add weight and complexity but the advantages of a near 100% efficient intercooler would be huge.
Is there a rule that would forbid it?
