Looking for an upright cooling system for a big motor. Not interested in one that needs the case to be machined. My engine is built.
Anyone use s CSP? How about one that used the 911 styyfan?
Thanks for info.

I have one in my bug that I made, sort of a stock T1/Joe Cali/ DTM hybrid metal shroud.
I've installed severial DTM's, a couple of Sharpbuilt, FAT...


I haven't done one in a 914. Why do you need one?

My '67 bug, T4 conversion, I made the shroud, 2600cc, 102mm nickies, JE's, SDS EFI, 46mm TB's, etc coupled to a 901 (911) transmission with stock 914/4 gearing.

Got a big engine and going to see track use.
Anyone with a 911 style fan out there?

It's been talked to death, on a type 4 a 911 fan isn't as efficient as a T4 fan, it moves too much air which I know sounds odd, but it also doesn't do it evenly.

My choice would be stock cooling or:

- 914 DTM, external oil cooler required. Uses stock Type 1 alternator and fan. https://lnengineering.com/type-4-store/dtm-...ic-dtm-kit.html

-Tangerine racing has an horizontal fan kit. http://www.tangerineracing.com/engine.htm

Con for both systems is if the fan belt goes you lose your cooling.

How far do you think stock cooling can get you if you also run an oil cooler?

100K miles but not all at once....

That made me almost snort my coffee - good morning to you.

What I am really asking is life expectancy on a build like this - I’ve heard 30-40k before it comes apart again and am wondering how much / if any this sort of upright cooling extends that (which I think aligns to the OP question).

Impossible to state exactly obviously, wonder if there is any ballpark learned experience.

Thanks!

A +1 on the Tangerine system, if you're going that way. I have one of Chris' Prod engines with that cooling system in my vintage racer and it's pretty cool (har-de-har). Not cheap, but if I was going that direction that's the avenue I'd take.

Depends

Only gentlemen racers are going to get 30-40K.
Many guys tear down and refresh the engine yearly or every few years.
More serious racers (AKA have the cash) will have a backup engine and may refresh the engine(s) throughout the season.

The big thing is the quality of the build and is it well sorted.
Not a cheap game, even with all the best kit shit happens.

One of the best things you can do on a tracked aircooled motor is monitor your temps carefully. I am conservative on the oil temps and prefer not much over 200 degrees personally. This usually means a substantial front mounted cooler for a tracked car.

You can also monitor cyl head temps, especially if you are concerned about them. My experience is more with 911 motors, but I've understood this is a challenged area for the type 4s. On a 911 you like to see 200-250 cyl head temp. I'm not sure for type 4's. I'm sure someone here will know.
