By NEC, it would require a 50 amp breaker, too. Not too many 50 amp single pole breakers used in residential, if any at all. The biggest breaker typically found in any home is the 40 amp 2-pole 240 VAC used to power the range.

The rated "peak" hp is usually a far cry from the actual power the unit produces. This is one of the reasons many suppliers of air compressors, for example, give the manufactuer's claimed hp and an "real horsepower" rating.

You realise this comment makes you sound totally ignorant about turbos right?

friction=heat????

The heat generated from doing this would be less than the turbo experiences during normal running.

:rolleyes:
had no clue that rx7s were equipped with ball bearing turbos. Or most any stock turbo for that matter.
:rolleyes:

You should have done the video with the vacuum as far away as possible.

Aaron Cake 07-29-04 03:44 PM
I just watched the video...Scary...That can't be good for the bearings, regardless of heat. I doubt there's enough oil in there to keep an oil film in place...so you're probably close to running metal on metal.
