Too Much cold air?
Living in Minnesota this time of year every ride could be your last one. I have noticed that the colder it gets the engine gets more powerfull. With air temps around 30* and low humidity the Ls1 SCREAMS!
I have a Vararam, so I know that I am pulling lots of cold air in.
Can too much cold air harm the engine?
Or what tempature is too cold?
Keep in mind I do get the engine up to temp before I take it out.

Yeap The LS1 (and most other engines) loves the cold air..so long as you get up to operatring temp I don't think too much cold air could be bad but I am sure someone will disagree 
it's too bad they throw so much friggin salt on the roads otherwise I would drive mine more during the winter

I've driven my Z with a Blackwing in temps below ZERO and the car loved it. Only problem was traction, frozen tundra and ice cold GY F1's equal ZERO traction. I was out showing my broth-in-law the car one morning and even at 40 MPH I could feel the car was basically in a four wheel drift taking corners. After a while I got comfortable (and I guess the tires warmed a bit) I was able to get a little more agressive. He has a V-12 Jag and the first time he rolled into the throttle on my Z he almost lost it (thank god for TC/AH and the fact he's a good driver used to Wis conditions). Once he found the limits he was having a ball. He hadn't driven a vette since the 60's. I was impressed.
Cold is good.

They do love the cold. I seem to remember reading that it is something like an additional 1.3Hp per 10 degree temperature drop...not sure if this is exact, but close. I can't imagine a scenario where you can get too much cold air. I mean maybe -50 F. air temp would be rough on a cold start engine but I don't think you'll damage it driving a warmed up engine during the winter months.

Just don't do the TB by-pass mod and you'll be all set. The TB had a heat line that helps condensation on the throttle plates and helps the car get to operating temp quicker. (from what I understand from here)

You should have no problems with cold air. These engines really perk up when it gets cold.

The only thing you have to do is be more patient while oil temp comes up.

If it will start, it's not too cold. The Fuel Injection System compensates for the changes in air density. More air = more power.

Sunday, I went for a cruise, and managed a whopping 9.6MPG. I guess I have been having a bit more fun with it knowing that every drive could be the last of the year.
