when is it to cold to start the car up in the winter with the blower hooked up? what are the specific temps not to start it up. i read that vortech says not to start it up on cold winter days. my garage isn't insulated so it will be pretty cold.

 

Our systems do not suffer from that limitation. In fact our industrial division provides a system that is used in aircraft wing de-icing. You are subject to a temp restriction with a Vortech SQ series.

 

Just let the car heat up for a few minutes before you drive it. If nothing else, you could put a heat lamp near the blower at night when you plug in the engine heater.

How does a Procharger not have similar problems? The bearing clearances should be just as tight, plus it's not using engine oil which would heat up slower. Maybe this is part of the reason behind the self contained blowers leaking oil into the intake?

 

The Procharger does not have a similar limitation and a leaking SC blower is an anomoly, not a characteristic of the design. I believe the SQ - helical geared Vortech units are the only ones with the temperature stipulation. More detailed information should come from the source, (Vortech) not a competitor.

That being said our lubricant was developed to maintain protection and performance over an extreme temperature and rpm range and we place no temp stipulations on use, or head unit cold soak. The only trouble would be from trying to chill the body of the supercharger artificially (before a race). This will affect critical clearances as the body of the supercharger would not be at a uniform temperature.
An exhaustive amount of development is done on bearing design and this contributes to the higher rpm capability and stability of the unit.

Self contained blowers do not have the same clearances as oil fed units do, at least ours don't.

 

nope i won't be driving it just letting it run till the fans kick on. i will just play it by ear then,if its below like 20* i won't start it.
