I use my supercharged 318 everyday to work - about 70 miles round trip every day. Its never been in freezing temperatures untill this year. Is it ok to run these superchargers in the freeze? How low is too low?

Make sure that the oil is appropriate for the temps expected.
Like anything else that has greased bearings, take it easy for the first few miles until things warm up.
Too cold? I'm thinking < -15*???? Below that, bearing wear in all components can be a problem.

I have the same setup. This is the first year I have run it in the winter. Up to this point I haven't had any problems. Like bob said, just take it easy until it gets warm. If you drive normal, you wont run boost. If there is no heavy load, there shouldn't be any problem.

Oh yeah, and once everything is up to temp, you should run better than in the summer. Cold air in = happy motor.

I havent had any problems yet either - down to 15 degrees so far - I cant say whether my performance is any better as I have put about 500 lbs of weight in the bed for traction on these mountain roads (bummer). I sure miss florida.

I was running 13psi intercooled on my built 318 and it froze up with ice and locked the belt up. I had to replace the belt, impeller, and a few other things. You want to make sure your not running higher than 8psi intercooled in 20 degree weather. Otherwise you will freeze up. I could get by with 8psi intercooled in 20 degree temps. As long as you don't run it hard, at a really high psi level in a really cold temperature you shouldn't freeze. I think it also depend on moisture in the air.

How does the high pressure freeze the charger?

Well, it freezes, because it pulls the air through the the supercharger so fast. It starts to build up moisture and because the air is so cold in the winter. The cold air causes the moisture to freeze on the blower. Then it just gets worse from there on out. I have only found this to happen when I am running 12psi or a little more. Also, if you have an intercooler, that can cause it to get colder and freeze fast. I only had mine freeze once or twice an that was all, but it was about 20degrees. It has to be pretty cold and you have to be pumping alot of boost for your unit to freeze.

I drove mine last night,it was slightly above freezing. The A/R jumped to dangerously lean.
typically it is too rich . I would definatly recommend an air/fuel guage if you are planning on running it in the cold
