Cut down radiators? Cooling issues?
I need a new radiator and have been looking at RSD and dewiit. I like the cutdown and plan to use a custom 4 inch intake with my blower. Are there any cooling issues with these? My car is black and on 90 degree days it gets rather hot. RSD is going to have a black friday so now is the time to pick one up. Any experiences?

Is the SC the only mod, other then exhaust I am sure? What temp do you fans come on? I have a SC coming and my car never sees 200 coolent even on hot days after beating the **** out of it. I hope a SC doesn't increase that temp 10 degrees......Now I do see 210 oil temp when beating on it....I had a black car once and sitting in the car gets freakin hot, but never paid any mind to the coolent temp..

No, it’s long tubes(coated), cam some other stuff. I also think my radiator is original so that not helping. A friend of mine had a similar set up and it didn’t get as hot as mine but he had a Dewitt’s and a silver car.
Im fairly certain 95 percent of my cooling problem is the factory original radiator that is 17years old.

Have you pressure tested the cooling system? An air bubble or small leak can cause coolant temps to get that high.
A set of really high quality fans can work wonders on these cars as well as opening up the front up and building ducting to channel air to the radiator.

The dewitts fans should help but I would also recommend pressure testing the system and burping it while you are at it just to ensure you don't have air trapped in the system and/or a leak.

Good idea. LS engine can be a pain to burp. Usually lifting the from end and pouring in coolant in the top hose helps.

I have the full Dewitt's setup on my supercharged vette with the oil cooler and it hasn't done much for cooling. The **** still runs hot when I turn on the ac I see 130+ temps. C5's were not built for superchargers and once you toy with the stock airflow it is never the same. Hopefully you are able to keep the stock setup and didn't go front mount.
