That was a good quetion I once had. I did some looking on vortechs website and its good up to 20psi. Ricklee is supposidly pumping out 15 psi in his 2.7 cougar. He had an intecooler made by spearco. I am not sure weather it was air to air or air to water. What do you think about vortechs intecooler units? There was one unit that it looked like if you clocked the outlet that it would work with are cars.
