radiator talk!!!
so what is the general ideal of a cut down radiator for a supercharger setup or running the standard height (OEM size)? for those that are running the cut down one what are you cooling temps at? i am on the fence as to which one i want to get and would benefit me more thanks

I have a full size dewitts with a 4" inlet pipe... I would recommend the full size over the cut down due to the added cooling capacity... you can use an aftermarket cradle, spacers, or have the stock cradle mounts cut and rewelded to move the radiator down a bit so that the inlet will fit

I have the Dewitts as well but I also have the Tiger Shark front bumper which lets a little more air in to the radiator and my temps run between 190-210 on 90+ degree days, and I do have a Supercharger. I hope this helps.

I did open the front license plate area so that does allow a little more air to get through but not as much as the tigershark... depending on your intercooler size air will have to flow through that, then your ac condenser, and finally the radiator and air will take the path of least resistance so you can lose a lot of that air around the sides... this is another reason the lower air dam is so important, even more so on a blower car with an intercooler blocking the front, because it is directing air straight up to the radiator... I wanted to box my radiator/intercooler/condenser in with sheet metal to force as much air as possible through them but I don't have any cooling issues so I haven't messed with that yet

Mines cut down cools fine with ac on in Florida heat without license plate cut out. I do have separate trans cooler mounted under headlight. Funny I have the cut down radiator but have not changed the inlet pipe yet.
