So if I run these:

Do I need these?:

This is a 1600dp motor with heater boxes. Maybe it's a stupid question #-o

If you are running the engine as an upright type 1 or 2, do not use the first pictured tins, but do use the second on any type if you are using the heater boxes or J tubes and industrial tins.

Super Cool Tins are actually Type 3 tins. Type 3 had the fan in the back of the engine blowing across the cylinders. A Type 1 has the fan on top blowing
down.

So you should use Type 1 tins on a Type 1.

The sleds keep the thermostat in the warm air stream, direct the hot air out the back end of vehicle, and also protect the pushrod tubes from road debris.

I've seen several threads on here of people with damaged push rod tubes from running over a truck tire, tree branch, etc. Invariably, they omitted the sleds which would have protected them from this damage.

My vote is to use the correct type 1 tin, and to keep ALL of the tin pieces, it's all there for a reason.

It's one or the other.. .not both.

Ok got it! They market the "Super Cool Tins" as if they are superior for all applications.

Actually they work very well on upright cooling.
A lot of people where i live run them with great sucess. And we see temps in the 115-118 in the summer.

Then how come VW didn't use them on the Type 1 engine?

Glenn,
i guess you would have to ask VW.
All i know is people around here have had great sucess with them.

Sled tins

Keep your PR tubes from getting hit with road debris

and

allow the thermostat to work properly, by not getting "cooled" by under-car air as you drive

and

The engine runs COOLER (when hot) by creating a low-pressure exit for the hot air to quickly vacate the area under the heads and cylinders.

Can you fit sled tins on an engine with A1 Sidewinder exhaust and heater boxes? No thermostat planned, but may have some flaps that are fixed open.

Question... I see you guys saying not to use the super cool tins, but No one really said why besides they are for a type 3. So, Why are they no good for a type 1? Do they not cool better?

Fri Aug 20, 2010 2:09 pm

All i can say is what i've personally seen and used.
Works for me.
People like Gleen say things like that without trying it for themselfs.

Fri Aug 20, 2010 2:27 pm

Well I trust what Glenn says, he knows his stuff. I'm just looking for a why they work, or why they don't, not just because its from a different engine.

Sorry to tell you but you are wrong. I had a set of type 3 tin on my 1904 and it ran on the warm side. When I took the heads off to fix something and I replaced the type 3 tins with type 1 tins.

Guess what.... My engine ran cooler.

So don't assume next time, just ask.

The Type 3 has the air blowing across the cylinders and not down like the Type 1. The tins are different because the cooling system is different.

Jake Raby has performed tests involving these tins, may want to ask him his thoughts as his research and testing has been extensively documented.

Fri Aug 20, 2010 3:21 pm

Yes, i know Jake has googles of data.
All i was saying what i have seen and used in my own personal car and talked with others in my area that use them.

Fri Aug 20, 2010 3:29 pm

Whatever works.

Bob Hoover had good things to say about them :wink:

http://bobhooversblog.blogspot.com/2006/11/vw-kool-tin.html

"I think it would be very difficult to not get better cooling using tighter lower shrouding, unless you installed it in such a manner that it could come loose. Some of the most valuable time you can spend would be to study the lower shrouding on the Corvair, VW Type IV, and most aircraft engines enclosed in pressure-cowlings. When you compare these more efficient cowling methods to the early VW engine it will make the short-comings of the deflector plates painfully evident."

I totally agree!
Glenn, you said you noticed higher temps with the "cool tins",, was this oil temp or head temp?
