Just saw this after searching to find more info on supercharger straps. Wasnt sure about what they were for, just remember seeing a camaro with them on it. Is this a common thing on massive Weiland chargers? www.streetfire.net/video/Blower-Blows-up-in-guys_26102.htmAnyone got any more info on this? Also, lets see them 'charger straps!!  |

Usually used in conjunction with a 'ballistic blanket' if memory serves me right, to stop all sorts of expensive engine internals turning into missiles.....

Because these type of blowers use fuel to both power the engine and help seal the rotors inside the blower, there is a distinct chance that when you get a backfire, it will ignite the entire lot inside the manifold / plenum. And becuase the blower is so well sealed it can and will shoot the blower right off the engine and a long long way into the air!
The straps and ballisitc blanket are there to prevent it going to far when it does happen.

That went bang because it leaned out, you can hear the change in exhaust note just before hand.

I saw one kaboom come off a Budweiser funny car at Santa Pod when I was a kid. It *almost* reached the crowd it went that high ;D

"Stuff" comes off these monsters regularly. Usually without incident, thanks to sanctioning body tethers, blow-out panels, plates, fences, and automated suppression systems. But it is still highly dangerous for both fans and drivers. Yesterday a woman in the grandstands at Firebird was killed when a top fuel slick departed from a crashed rail and flew into the crowd.

Seen it a few times at Pod, but the straps do a good job normally. Someone was killed at Santa Pod a few years ago after a ring gear departed from a blown flywheel and went in to the crowd at the end of the strip  |

I thought that was a blower belt at the pod?
