Type 1 engine tin?

[slantman]

I'm in the process of replacing the worn out 1200 in my 65 Type 1 with a healthy 1914 turnkey engine from DRD. I have a question regarding the need for the tin that goes behind the engine, above the bellhousing. I have a pic of it below:

Do I need to keep this piece? The car is mainly street driven, with the odd run down the strip. I thought about leaving this piece out to help feed some more air to the dual 44IDF's, as well as help with cooling. My car has the standard sedan engine lid and doesn't have raised hinges, though I may look into that for summer driving. Thanks.

Many will say, and I agree, that every tin on the motor has its importance. Inside an engine compartment is where all the tins hold some type of importance, mostly to keep heated air from the hot exhaust piping from recirculating back into the cooling system. I would suggest reusing it.

you will have more fresh air in the engine compartiment if you remove it. but also more dust !

You'll have more heat since the #1 and #3 exhaust pipes are just under that tin.

BTW... You'll need one that made for a dog house shroud... that one will not work.

you will have more fresh air that come under the car than heat from the 1 and 3 exhaust. But again, you will suck more dust too.

There is such a thing as too cool. The engine needs to be at "operating temp" to be most efficient. That's why there's a thermostat.

Don't anticipate a problem before you have one. And if your engine is running hot... find the cause, don't remove tin.

If i can get a large displacement engine in a fully enclose engine bay to run "correctly" then so can you.

Thanks for the replies.

Okay, so I'll have to replace it anyway. What is the correct name for this piece, so I don't sound like a total noob when I go shopping for one to suit the doghouse cooler?

As Luftwagen shown us previously, this summer I have installed an air duct like this http://www.stockcarproducts.com/brkduct.htm

That's work very well ! just need a screen.

I need also more fresh air because my engine is turbocharged ( draw through) so with the turbo inside the engine compartiment there is more heat. But you don't need this tin, especially with your engine. Or you you can install this air duct.

It's not doghouse, so he doesn't have to worry about recirculating hot air from the oil cooler.

As long as the "sled tin" is still in place, that piece of tin can be omitted with no ill effects at all, other than a cooler running engine.

If you want my opinion, leave it out. I left it out on all my VW's, daily driven, and taken on 40 mile dirt roads on camp trips. Long highway drives, and stop'n'go traffic in 115 degree heat in Vegas.

The key being, if the sled tin is in place and its a non-doghouse, it's perfectly safe to leave it out.
