Cooling issues...

[OrangeCrush]

Okay, where to start....

When I put the supercharger on (Maggie) I installed a two core aluminum radiator. I installed twin electric fans (4600 cfm) but they did not come with a shroud. I thought I was ordering the set and they had shrouds but apparently not.

The recommended place to put an intercooler is immediately behind the grille.

Instead I bought a larger intercooler and mounted it in front of the condensor. (thus making me mount the oil cooler between the radiator and engine)

I then put the transmission cooler where the intercooler should go.

Anyway, the truck runs a hair over 210 (still have the 190-195 thermostat in it, when I put the 160, it overheats)

Today was in the high 90's and the truck ran into the 240-250 range in stop and go traffic.

I guess my question is, Summit racing sells a dual fan (6000 cfm) setup with shrouds.

Do you think shrouds make that much difference?

Thanks,

Mark

I take it that thermostat didn't work right?

When I did my small block conversion in my Jeep, initially I had no shroud and engine temp would peak at about 250. Once I installed the shroud it only peaked at 215. That is using A fan clutch, no electric fans.

Yes, you need the shroud. It will make a huge difference.

I never had a problem with that, but Fubar did. He went through all kinds of crap.

I don't know if it was ever corrected.

Get the one with the shrouds and be sure to install a cutoff switch in the cabin. This way you can turn it off when you charge through a deep water hole. I shredded a pair of fans deep on the trails doing that. We went back to the original fan clutch after that.

Good luck.

Mark,
I just bought that other set of dual fans that you didn't like the shroud on. I got them for a REALLY good price of course. Why don't you try them out when I get them and see if they help. Ifo so you take them, if not I'll put them on the back hatch of mine like a jet car.
