One good reason not to lean over the blower when playing around with the drag car

[Tiny]

There is something to be said or burst panels and blower restraints!!

A friend of mine who had owned between 150 and 200 hotrods in his life was telling me a few years ago about a 32 rod he had which needed four (two sets of two) seatbelt material straps 150mm wide holding his blower on. Any less and disaster struck, although I can't remember how he knew he needed that much and only that much...

I think I'll build turbos instead

Just so you know heath... Blower restraint systems... seatbelts.. are used to hold the bits of a popped blower. instead of having them go flying like this one did.

You dont ( cant) rely on the straps to hold the blower in place except in the envent of an emergency.

All the race blower systems ive seen use an aluminium type bolt to bolt the blower to the manifold which is designed to break under teh force of a backfire through the blower system. This then separates the blower from the manifold and the straps catch it before the driver does!

Most supercharger applications ( if not all) use a burst panel these days to eliminate these kind of problems.. Basically just a weak peice of metal that will blow out before the blower pops off! Nothing is foolproof though!

Cheers.

poor bugger....

bugger!
it looks like it did have a burst panel, you can see it blow out in the slo-mo, but some straps would have been handy

The burst panel is the alluminium plate at the front of this intake manifold next to my hand isn't it? Stops the supercharger from ripping itself apart by being forced to run in reverse yes?

Pretty weirdly shaped bit of excitement

What makes you think it isn't just an obscenely pronounced section of muscle? hahaha yeah it's either my phone, camera, wallet or a combination of any of them.

The burst panel is the rectangular piece of metal that's bolted with many small bolts to the front face of that manifold.. just infront of your hand.

It's supposed to be a sacrificial plate that will explode and vent any gasses in a safe direction ( often they need to use a funnel to point gasses safely away in something like a funny car for example).

The restraint system, and the blower bags that are now compulsory are to stop debris from flying around in the event of a bang.
If youve ever seen a fueller REALLY blow appart.. You'll see bits of shit flying everywehre and blowers hanging off the sides of blocks everywehre!

I was told a story by my mate who crewed on many fuel cars in the past when they were still front engines slingshot design of tapping the driver on the helmet just before they pulled on teh stage lights... " Hey Jim (read).. we hopped it up.. 1000ft and DUCK" *whack* closes the visor.

^^^ Hey Matty....WE GOT ONE!!!!!!!!!

Ha ha ha, sorry Heath, couldn't help myself!!!
What, no windows?

Yeah, those blowers are called that for a reason 'eh?

[Heath]

hahaha Dick I like that one. Nice try though. I wouldn't have posted it if I was embarrassed, lol.

I'm fairly sure it uses shockwave flash to play via photobucket

Give that a go chop
