Could radiator be used as an intercooler?
as long as the boost was kept below 15lbs?

Any reason why it wouldnt be a good idea?
I would say it wouldn't work because radiators probably wouldn't hold up to that much pressure, and I don't know if air would flow through them as well as water does.

I'm sure the usual 1" inlet / outlet wouldn't be too great for flow, either. Besides, a decent intercooler can be had for $50 or less, thereby eliminating cost as an issue.
Sure it'll work.

You also might try using a radiator cap as a blow off valve, and an EGR as an external wastegate.

[Image: smile.gif] I'm just kidding, honestly, the physics/functions seem similar but it'd never work.
Might work, but not very well. A typical IC is an air to air heat exchanger, and a radiator is a water to air heat exchanger. Water and air have WAY different thermodynamic properties, so a radiator is designed way different than a IC.

.. i also don't think a radiator would flow the air NEARLY as well as an actual intercooler..
