On the spur of the moment, I decided to drive Pearl to a HUGE car show last Sunday over near Boston (about 500 cars - That's Wicked-Awesome-Huge for New England).  That meant driving along the Massachusetts Turnpike (I-90 to you non-Red Sox Nation folks) and then doing about ten miles on the infamous Boston inner-ring of Route 128 (where all of of the high-tech firms settled since about 1947) for about an hour of turnpike driving - All in 90+°F heat.

 

The traffic was AWFUL, but all that awful-ness was going the other way and I was flying along, keeping up with traffic and turning 3,000-3,100 rpm.  I instantly loved my newish, 3:88 final gearing.  Once in a while things would accelerate to 3,250 or so, but then would settle back down again with everyone doing 65-70 mph.

 

On the way home I needed a nature break, so I stopped at a rest area on I-90 and immediately jumped out and tested the oil temp (while running) with a dipstick thermometer and it was running 190-200°F at turnpike speed (Natick, MA temps were at about 92°F from my phone).  This is with a relatively sealed, CMC engine cover, an 8" hole in the firewall right in front of the fan inlet, all of the proper engine tin, air vanes, thermometer, etc., and all of the heat shields in place and sealed.

 

THIS IS FRIGGIN AWESOME!!!!!!!

 

I love it when you listen to what others are doing, see their success (and occasional failures) do the good things and they work!!

 

I'm not quite ready to tackle "Death Valley", but I'm certainly ready for anything New England can throw at us.

Gordon-are you running an external oil filter with oil cooler? If not, what is your setup--oem?? Getting ready to put my 1835 back in and after reading so much on temps, visiting Carlise and seeing many that are not running ext coolers I'm on the bridge which way to run. Being the car is new to me and PO is deceased I have no prior knowledge to how the temps were on this CMC--sat for 8 years and even thou it fire right up I had to go thru tank-line-carbs etc cause it was gunked up--Thanks, David.

David:

 

I'm running a type 1, 2,110.

 

My fan shroud, fan and internal oil cooling tower is a stock system from a 1971 Beetle.

 

In addition, I run a DeRale, fan assisted, 16-pass external oil cooler tucked up into the rear of the driver's side rear wheel well.  The fan starts automatically at 180°F, and there is a filter in the external circuit.

 

It seems to sit at 190-200°F at turnpike speeds, slightly less off the turnpikes.

The PO removed the oem cooling tower and ran and non fan external cooler directly in the way of the fresh air inlet for the shroud. That has been removed--other have said--Bad Idea--I'd second that too. So your lines are running from where to where? Mine has the external filter and I'm planning right now to add a thermostat inline with the filter system. There is a 2 line block where the oem cooler was and lines running out the back of the shroud. I really only want to do this once because of time and cost. I have picked up a cooler with fan from another member here--just not sure which method I should run. The rounded shroud has no internal flaps and there is no oem thermostat on the engne under the tins. So--any suggestions. Nothing worse than a hot engine on an aircooled--be there done that way back when I play with VW's before.

My apologies if I'm telling you stuff you already know- 

Use a doghouse cooler and shroud (plus the thermostat and flaps) for quickest warmup and the most air directed to the heads when the engine is at operating temps. Plug the outlet of the pump, install a full flow pump cover to add the filter and then plumb back to the case. You can add an additional cooler (and thermostat so the oil doesn't take forever to warm up, as cold oil causes more engine wear as well). The thermostat switch for the fan on the additional cooler should be BEFORE the cooler, so the fan only when runs when needed. Hope this helps. Al

OK, but that was Al providing that bit (he's taller than me, but I have more hair).

 

His diagrams show the same routing of the hoses, but I have an electrical switch just at the inlet to the external cooler to turn the fan on and off.

 

All of my info is up in the knowledge section on this site.  4-part saga, starting here:

If you're referring to me, Gordon, I'm sure you have more hair than me, and at a statuesque 5'6" you're probably taller than me as well. And I need glasses so I can focus on anything closer than arm's length. Boy, I'm glad I'm already married and there's beer (and rum), because I'm short, bald, and wear glasses; when you put it in print, life sucks! Oh well..

 

PS- I didn't mention it earlier, and I don't know if Gordon's article does (it's well written and thorough, so it may), but when you plug the output on the oil pump you may want to plug the matching opening in the case, due to the poor fit (a lot of pumps are too small for the opening and can leak if the outside is not o-ringed) so there is always proper pressure when the engine is at operating temps.

Yeah, I don't notice the height differential until I'm caught in a group shot like this one at Prince Edward Island.  Good thing I had my helmet on - makes me look taller.  Of course, I'm sandwiched in between the two tallest riders, too....

 

We're a colorful bunch, aren't we?
