Title: Heat from exhaust
Post by: Dinadin on May 07, 2012, 07:38:59 AM
I am curious to know, does everyone else have a problem with heat from the exhaust heating up the cab of the halftrack while it is running?  It feels great when it is cold or cool outside, but when it is 90 and humid it gets almost unbearable.  Is there supposed to be some kind of shield on the muffler and exhaust?  A guy locally restored a scout car and he installed some heat shielding fabric underneath the floor plates, but I am not sure if that was actually done to halftracks or not.  Not that has stopped me before from doing something that works.  After about 30 minutes of running the floor boards above the exhuast are hot to the touch and it is a sauna for anyone sitting in the passenger seat.

Or is it that I have another problem and it is running hotter than it should?

I don't know about others tracks, but in the summer mine is like driving a sauna after 30 to 45 minutes. As long as you keep moving at a good pace the moving air keeps it bearable, but slow to a crawl and its HOT.

I just spent the day driving mine around town and yes is gets warm. In the morning it was fine but this afternoon when it warmed up it was hot. I think it is just the nature of the beast. Just think how warm it gets inside a tank. To warm for my blood.

It is good to hear that I am not the only with that problem.

On a side note, what are the floor vents for?  Are they for bringing heat from the engine into the cab in winter or to allow cooler air to flow in while moving?  I thought of that this morning.  Mine were welded up years ago and vent tubes are long gone.  I had always thought it was to bring the heat in to the cab, but depending on how long the tubes were it might have been able to get cooler air in.  I am just curious.

There is a cloth wrap you can buy from most speed shops and you can wrap the exhaust pipe with it and it helps quite a bit. I think racers use it to wrap headers. It looks similar to the original cloth (asbestos) wrap I've seen on some scout cars. The scout cars also had an asbestos impregnated sheet under the tranny floorplate and on each side of the tranny hump panels but i don't think i've seen that on halftracks but can't recall for sure.

That is probably something similiar that the guy I know put on the scout car he was working on.

That's about as close as I think you'll get to OD.  If anyone tries this, let us know if it makes a difference.  This is one modern modification I think I can see doing...just need to get the track together first!
