Okrasa oil cooler

[Ninamashr]

If I was to install an Okrasa oil cooler kit to my 36hp would I have to remove/change the cooling ring in the fan?

Hello-

If you do add one, I would love to see some before/after temp' data.

I don't think they make enough difference to go through the trouble.

Just by eliminating the throttle ring you should get better cooling. By putting the copper coil in its place, you are once again reducing airflow. I'd try it without the throttle ring first and see what that does for you.

Speedwell offered an oil cooler for placement in front of the fan intake. From my understanding, it was and still is a very bad idea. Now, when it comes time for me to build my speedwell sprint kit engine, I'll probably install the oil cooler just to in tune with the vintage gods.

new to 36's, what does the cooling ring do and do I need it? lol. I don't think my '55 36er has one. I'll check tonight

I wouldn't call it a necessity if you only drive in warm weather but it's the equivalent of flaps on later engines.

yeah, it's a vert so most likely I will not be driving it in the cold. I usually let my cars warm up for a minute or two anyways. I'll look tonight to see if it's there, doubt it though.

funny about the cooling flaps on later motors, in nor-cal, I really havent seen them too much. Every vw I've had has them removed. must be a CA quickie rebuild thing

Just came across this. Several people told me that here in Southern California, that the cooling ring was not needed due to the mild climate and it was one of the first things that was discarded, at the dealerships is what I am lead to believe. I left the cooling ring in place, simply because it was functional and I like that. Have installed the okrasa cooling coil and positioned it forward slightly to make sure that it clears the cooling ring as it moves out. Body is currently off of my 56 bug and I have had plenty of opportunity to run the engine and observe the interface with the cooling ring and the cooling coil. All looks good and operates well. Eventually I will supercharge with a Judson. Love this old machinery, love to keep it running.

I am of the old Mottoe! If it left from the factory with it ( Regarding The Engine) Then for my own piece of mind my 25-36hp motor's will also have it installed.
Now as far as the after market oil filter/ oil cooler, such as one manufactured by Steph. in Europe for the Judson or Okrasa line kits there is no other alternative but too eliminate the Fan shroud ring all together when running the Oil filter/oilcooler kit. Other than that if going stock set-up run the ring Eric (VMR)

My setup came from Steph. I let him know that I wanted to retain the operating cooling ring and he adjusted the design. I have it all. I will post some photos of my setup when I get home tonight.

Here is a shot of the cooler with the cooling ring

Enjoy!

Yes, exactly. I will still post photos of mine this evening (if I can relocate the primer as to how to post photos). Slight differences on mine as both the supply and return come over the shroud to the front, but the setup that you show is it, that is, the cooling coil held by a clamp secured to the case. I really liked this setup as it allowed for adjustment and proper placement of the coil assembly so there is no interference between it and the ring over the range of the ring movement.

Question, where did you get the small clamps to secure the flex return line to the top of the shroud and, is it a rubber sleeve, no temperature problem I take it.

Charlie

They are rubber sleeve, Steph included them with the kit.

I haven't run it yet to find out if the temp will be an issue, but if it is I will use metal clamps. I already heated the thermostat to check free movement of the ring and it works AWESOME.

I prefer to keep all original parts on the motor, so I think having the ring in place is appropriate. However, like everyone has said, being in California it's probably totally unnecessary. I just like how mechanical it all is. Who am I to question German engineers???

[ProjectX]

Sorry, my lines are set up for an external Fram filter, that's why the return doesn't come back over the top of the shroud.
