I was looking in Hot VW magazine the other day and saw that you could replace all the engine tin in a beetle for about $50 with Chrome engine tin.

Does anyone know of a supplier for 914 Engine Tin? One side of mine has some acid pitts in it (guess which side!!) and the other was creatively cut a little by the PO so having mine chromed is not an option.

Any pics of chrome engine tin out there? I think it'd look good, but might just be gaudy as hell in person.

Chrome tin doesn't get rid of the heat from the engine. If you want a hotter engine chrome the tin. Post in the classifieds for the tin you need or call Rich at HPH in Calif.

Unchromed Tin disipates heat better than chromed? I didn't think the chrome would add extra cooling, but why does it make it hotter???? I don't get it.

Hi,
I think black dissipates heat better. That's why radiators are almost always black.
Cheers, Elliot

as i understand it with limited chemistry, chrome acts as an insulator, not a good one, but any insulation at all would make the engine hotter...

Chrome tin is only good for show queens. Really, it hold the heat in and the engine will run way hotter.
Have it powder coated Gloss Black or whatever color and it will look nice for awhile until all the oily grime gets on it.

OK, if you chrome your tin, I won't ask you and you don't tell me. (IMG:style_emoticons/default/wink.gif)
Deal?

Bigger mass = more stored energy, plus an exponentially lower factor of thermal dissapation. I would bet chrome has a higher R/factor than the tin in the same thickness by.... oh 50% by itself.

Anyone ever seen aluminum engine tin, with copper vanes braised on?

Nevermind!

They say we all have chrome tendancies.

I like flat black paint, how about those Cowboys!?

Actually I just blasted all of mine and painted it Semi-Flat Black...that is one of my favorite colors for engine/suspension components. Now I just need some new screws for my tin.

As far as the "show queens" thing, Yes, after I meet my goal and get the FTD (or at least first in my group!) at the autox, then I do want her to look like a show queen sitting there. I would like to be able to take her from an autox to a car show. (IMG:style_emoticons/default/smilie_pokal.gif)

I also don't intend for any oily-grime to get on it.....maybe she is a show queen...she doesn't leak...

Gloss won't help, either. Flat black would be the best color in terms of heat absorption/radiation.

This was a huge discussion w/the VW list I'm on, specifically, the Type III air-cooled VW lineup (pancake or suitcase engine, like the Type IV). We have to worry about over-heating much more than a Type I (upright) engine. Though it was generally agreed that a glossy/chrome finish would reduce thermal absorption, with the fan blowing a constant stream of cool air all the tin does is direct the air flow and its color doesn't contribute much to the actual cooling of the engine. Air and oil are the major coolants for the engine. What contact the tin does physically make with the engine is small and insignificant.

We felt that painting the engine case would be a worse cooling offense than chroming the cooling tin.

If anyone has proof to the contrary I'm open to it.

Keeping the cooling tin, and ALL OF THE PIECES, intact and tight is very important. This includes any grommets, plugs and seals...like spark plug seals! An air leak means you have that less amount of air to use for cooling. A properly functioning cooling flap system is also very important for quick engine warm ups and even operating temps.

Does anyone really think that a different color would make a measurable difference in the tempature your engine will run. IMO, I don't think so.

It is all theory. If someone could prove it on a real world engine, I MAY believe it.

"My engine ran at 180 degrees with chrome tin and than I painted it flat black and now it runs 179 degrees." SURE IT DID!! (IMG:style_emoticons/default/idea.gif)

We make the rules, these cars defy physics, and cost too much.
