Is that really true you cant start the jeep with a vortech under 25 degrees ? i start mine everyday in new york this week it was 5 degrees when i started it?
theres also a brand new 3.8l on ebay for 3800 so I'm sure its cheaper to just get a new 3.8l long block... just wish these hemi swaps didn't cost 20k+ lol

What they are usually worried with low temperatures is that it takes longer for the oil to reach the ball-bearings and thus causes more wear. Large truck engines tend run pre-lubrication pumps so that you pressurize the entire system including the turbo before you start up. It saves on wear big time. They also have post-lube capabilities too. So, instead of running your engine for 5-6 minutes at idle after driving to work-- you can just hit a switch and the system continues to lube the system until you turn it off.

I plan on adding both system to my truck for my trip to Alaska.
Read the official word of Vortech:
Owners manual has an "important cold weather information" section: http://www.vortechsuperchargers.com/images/94.pdf
Warranty document specifically mentions a cold start-up under 25*F without a heater in the list of things that will invalidate the warranty: http://www.vortechsuperchargers.com/images/92.pdf
Like many other official limitations, I'm sure there's a "buffer zone" built in to their specification. If it seems to start just fine at temps below 25*F, is it causing accelerated wear and tear? It's up to you to decide whether to take the risk, or adhere to the guidelines to ensure warranty coverage.
For the Vortech specifically, it's more about tight tolerances (as they explicitly state in their owner's manual; see links in my previous post), so the problem would be different parts of the supercharger being made of different materials that expand/contract differently with temp changes. Below a certain temperature, you are at risk of having parts parts touching each other that should not be touching each other.
How do you guys feel about the stock jk exhaust on a 2013 being restrictive while running a ripp super charger?
