cool tins

ViolentBlue · 02-07-2000, 06:18 PM

are the lower deflectors, or cool tins on the type4 engine nessasary when converting to an upright cooling system?

I never got these pieces when I got my engine, and I wonder if I need them or not. I'm planning on putting my engine together soon, and need to know if I need these or not (otherwise I'll have to mess around with removing the pushrod tubes once the engine is together)

I'm converting to a Porsche 911 style upright cooling system, I've just arranged purchase and shipping for the fan/alternator setup, and will be buying the sharpbuilt porsche style shroud, as they are the only manufacturers of this type of setup that allows you to use your stock oilcooler in its stock location (that I know of)
Getting very excited as everything comes together.

OH ya one more question, on oilcoolers, my stock unit is cooked (melted, it came that way from PO) I need to get another unit. can a person use a used cooler? or is it recomended to buy new?

I think it is important to have the bottom cooling tin. Not only is it how the engine was designed, but leaving them off will give you a temperature gradient (difference) from the top of the cylinders to the bottom. These plates were meant to deflect some air around to the bottom, and without they just go down and out the sides.

For an example of what happens when you have a temperature gradient: think of putting a glass of icewater on the stove, it will crack. (a little extreme) But not so drastic for the engine just bad for wear

Can you picture it?

Both cars that I have had previous owners that didn't do things the right way. I feel that getting it right the first time is way better than going back to do it again.

Your local junkyard probably has an old bus, go out and see if ya can't gettum cheap.

I know of one junkyard around here that has at least one type4, I'll swing by there before I put my engine together, the cooling kit that I'm getting possibly comes with pieces that are supposed to do the same job, if not I'll get some stock units
thanks

and on the oilcooler question?

on the oil cooler...

What I would do is see the product before I buy it (if used). First look to see if there are any bulges when you look through it, as this will suggest that it may have been blocked by impurities in the oil that settled in the cooler. If that's OK, check for leaks by filling with solvent, and leave it on a napkin to see if any juice got out.

If you do purchase used, be sure to give it a good solvent bath and dry before putting it on your engine.

I can understand why you want to get a used one, those things are expensive.

On the lower cooling tin It is very very inportant the are there. Not only do the direct the air but they also slow the air down so it can cool the cylinder. Have you every seen a car that the thermostat was remove to help th car stay cool but it really hurts it rather than helps in the water flows so fast thru the radiator that it dosen't get a chace to cool off.

How much did you fan/alt setup cost?

In a T-1 car the oil cooler is very close to the body with there fan shroud.

I bought the 911 alternator/fan combo for $300 Canadian (roughly translates to $200 american)

I'm going to be using a sharpbuilt shroud which will cost about $620 with shipping

becareful with the Sharpbuilt shrouds. I stay on the german/UK message boards and they do not recomend them.

Try this out for size...
A.Knuf Power Tunning Parts in Germany has an VW/911 fan set-up. The shrouding is pretty much same as BAS's but the unique part is the housing for the alt. is designed for a VW Golf alt to lower the cost, plus everything fits and wires up just like the 911 alt. You can buy almost 2 Golf alt for the price of 1 911 unit

Dude you got me, not even seen that one, whats the web page adde to look at it. The problem with the fan shroud is the lack of direction of air flow within the shroud. From what Ive heard the sharp is pretty good. But I havent dealt with them a bunch. l_anderson@mailcity.com

do you know what the problems with the sharpbuilt shroud are?
biggest deal in chosing the sharpbuilt over the B.A.S. unit was the option of using the stock oilcooler rather than an external unit.
other than that they seem the same

I'm realy interest in the 911 fan with a golf alt. Can you give me more info. price, pics, web page. anything

Larry

Rare but not as rare as you think. I talk to guys in Germany/UK/France everyday online and keep up on Porsche knowledge. I talk to the guys at Volksworld mag on a regular basis, I even talk to Dr. Uwe Braun (he's the B in MBT) I talk to Mike Ghia, John Maher, Benard Newsbury all kinds of people if you are into this stuff like I am you will recognize these names. I also have a webring of webaddresses on my webpage with people right here in the US and Europe on it. If you would like I could put you on it after you view it. I have tons of internet links of GL (german Look) pixs and links, most are not on my page but saved in my computercheck out my page and tell me what you think. It is not the best in the world butthat's not what it was designed for. I designed it so others can see my progress and other peoples progress and give them links to Performance mods that is so rare over here. http://community.webtv.net/vw911/VWGermanLookPage
