anyone pic of stove pipe cooling?, looking into cooling for chumpcar Options

[usa4cheer]

Looking into different cooling options for chumpcar type race. I have looked at the cali conversion, different fan configurations. fan deletes etc. and was considering a stove pipe type cooling that I have only heard of and know nothing else about.

anybody know about this
thanks

that's quite a setup, I have checked it out on your website. very nice and looks well constructed, how do you have the oil cooler setup, did you leave the factory, or use a bypass plate and do an external cooler with electric fan? I would imagine that would be hard on the battery without the alternator. sorry for prolonging the topic but the cooling setup is my biggest obstacle, I am actually building a 914 for rallycross, it will be short runs like autocross, so I am debating an alternator delete too. I appreciate the help, I have kept up with your program for years, I have had 8, 914s in the past 15 years. good to see your engineering keeping them going.

The engines I've been running in that car have highly modified oiling systems.
The boss where the stock oil cooler inormally connects is cut off and the passages are plugged. Other significant oil route changes have been made to the crankcase as well.
Threre are two oil coolers up front. They're contained inside a box which gets air from the right foglight opening of the bumper. No fans. That would definitely be too much draw on the battery.
One of the coolers is connected to a two stage pump in the stock location, and the other one is connected to a belt driven pump which scavenges the rocker boxes.

Even the dry sump tank is something I fabricated to rather unique specifications. It fits in the passenger footwell and has a filler neck under the front deck lid.

Over the years I've tried a number of oil system tweaks. Some were improvements, others not so much, but I've never suffered an oil related engine problem since 1998. The basic system works flawlessly.

In my street car, the current engine uses the flat fan cooling system and has the stock oil cooler, fed by a take-off hose from the fan shroud.
The thermostat is a bi-metal spring attached to an airflow valve.
This allows the oil to heat up more quickly to a preset temperature and never go any higher.
