Peltier junctions are not very efficient though. Using a couple would probably require swapping in a lager GM alternator... not too big of a deal, they're not much larger than ours and they're pretty inexpensive.
Pelts also have to be cooled. The easy way of handling this would be to use a water cooling block for a PC and plumb it in with the cooling system. Wouldn't take much just a length of 1/2" hose... that or add a heatsink, but then you have to make sure the heat sink gets enough airflow.
To do somethinig like this and actually get a decent return out of it you would need to:
Upgrade your alternator
Insulate the intake piping (heat wrap or ceramic coating)
Make sure the pelts are well cooled
A setup like this would be FAR more effective than just a bag of ice set on the intake, but it's not the simplest thing to set up. A water injection setup may yield similar gains without the added power consumption.

sounds like a pretty interesting job?
anybody has any experience using this b4?
how reliable are they ?
