getting hot

[bulletbrown]

Dragon 462 , I had the same problem with my FE 390 . I took it to a speed shop and this is a list of things they found,
The March pulley's are to much of and under drive .
The radiator they came with the kit package was just to small , they like to rate them by the HP of the engine , a radiator manufacture I had on the phone Question that logic.
The radiator was replaced and moved forward and upright, it was tilted back.
Replaced the Mickey Mouse fan that came with the kit with a 2002 Viper fan assembly , cost 189 from Chrysler and is a two speed , a real bargin for the price , it comes with flaps on the corners that close at slow speeds.
I run a 180 stat. and I have solved the problems . Good Luck.

Maybe someone else has covered this, but the most important factor in cooling is not coolant flow, it is AIR flow. You need to be sure that every cubic centimeter of air entering the nose goes THROUGH the radiator, not around it. Plug every opening around the radiator, preventing any air from entering the engine compartment without going through the radiator. To test this theory, use duct tape for a temporay solution. Also make sure that all the air goes through the fan. You need shrouding for this to seal the fan and radiator. That Viper fan sounds like it's on the right track.

Don't get distracted by water flow - if it stays in the radiator a little longer, it just gets cooler while it's in there.

Sounds like you have all the mechanical stuff right.

I just looked at some pics of the Viper fan - that is the hot (ahem) ticket! The little doors allow air through the radiator at speed without distubance from the fan. When not moving, the suction from the fan closes the doors. The downside is that it is kinda ugly and cobbly-looking.

Dragon,

I agree with the comment on air flow through the radiator. When I had my Lone Star I purchased a really neat shroud and fan combo from Vintage Air that fit the LSC radiator, had the little trap doors and the fan pulled 2900 CFM if my memory serves me right. That in combination with some shrouding around the outside of the radiator to force all the air through the radiator cured any heating issues I had. Even in 100 plus degree days that we have here in Texas, the car ran at 190 - 195.
Here's a photo that shows it:
