I've got a stock 1600 tp in a "61 beetle & she has no air deflectors under the barrels. I'm after the T3 style for a bit of extra cooling as the doghouse setup runs hot in an early girl like mine. Absolutely, Definitely, not chrome.

Like this pic:



Also known as "supercool? cooling tin"
I posted this in the buying selling page and got a reply that suggested they might not be the best option on a type 1 engine.

I had originally seen them recommended on the Gene Berg website & would be interested in hearing peoples opinions on the pro's & cons of using them in my particular setup.

Thanks,

Matt.

What do you mean by the doghouse runs hot?

[ Edited on 1-2-2007 by VWCOOL ]

I have used them, chrome ones, from Mick motors. I could only get the chrome aftermarket ones. Not quite as good as oem but still much better that the t1 for having air go through the fins under the engine.

I dont have any data with and without. The engine I built ran really cool on hot days but this mod I dont think would show on oil temp.

I used them after reading some berg articles iirc. I drilled holes and used SS tie wire to hold them tightly in place so no rattles. I hate rattles.

Yes,
I have the chromed ones fitted to My Beetle 1600 doghouse fan shrouded engine...

everything I have read was good...

[apart from chrome] which shouldn;t be used as it holds the heat... I found that out later....

but many engine builders in the USA use them on all their race engines etc...

I don't think they need to be tied with wire as they are a tight fit.... they won't rattle...
the original ones were more likely to rattle...

cheers

Good find, Cef

My interpretation: With a Beetle's stock under-engine tin, the T3 stuff is redundant

I have read somewhere that dealers were recomended not to fit these to type one (upright) engines when they came out, that they were only intended for the type 3 pancake motor.

Cooling issues you have are likely to be caused by insufficient air entering the engine bay... maybe use a convertible lid? or jack it up slightly at the bottom, i have done this to my beetle(65 aussie) and it runs fine with a dual port/doghouse.

Best to open the top of the engione lid...

the air flows over the roof into the engine bay...

naturally this works better with vents in the engine lid so air can also exit....

big turn over of fresh air.... and engine bay keeps much cooler..

At least in summer....

I know it doesn';t look good....

but its better for your engine.... IMHO...

ctefeh,

Thanks for those links, in one of them there were some comments from Jake Raby, who had actually done the experiment with different tins on the dyno.

I'ts always good to find info that's not based on assumptions and/or hearsay.

I think I'll get me some stock under barrell tin.


Matt.
