Reply to "Looking for tall velocity stacks"

I saw one of the Cobra Coupes burn like that. I don't remember what year. 64 or 65. Daytonna or Sebring.

Everyone thought the car was destroyed.

It was back the next day and people thought Shelby had a hundred of them as backups?

It all depends on the nature of the fire. Gas fires are hot and they usually warp the sheet metal like the decklids.

I'm not sure why the front of that Pantera was burning? Maybe just from the heat, the tires caught fire?

I didn't notice what wheels were on it but magnesium definitely burns.



On the room above the stacks, this is what I have.

These are 5" tall stacks. There are 6-1/2" stacks, the source of which I could not find.

Those would have been too close to the clear plexiglass roof/roof extension that you see in this picture. It's there as a water shield so you can't take a hose and squirt it at the open stacks.

The silly aluminum panels on the carbs sit over the screens and do the same thing.



The screens keep large unfortunate animals like bears from getting sucked in.

Towards the rear of the engine, there is only about 1/2" clearance between the screen and the plexiglass.

That's where the top of the 6-1/2" stacks would be and is too close to put a screen on and the rule of thumb with stacks is that you want the same space above the stack as the diameter of the stack.

These stacks are 3-1/4" od, so this height is ABOUT right with those parameters.



The rubber in the screen retaining rings is rated for 400 degrees F. Where they are located that should be fine.



I'm thinking about putting Budwieser decals on the stacks? They do look like beer cans, so why not?
