Coolant Swirl Pot - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

irax · 08-23-2016, 03:54 PM

Has anyone installed one of these on a 86 ?

I used them on my 240sx with both the KA and the VQ35 and it made a noticeable improvement in temperature stability and lower temps as well.

Well, no.

Is this for grins or is it for real ??......

I take it you never used one before.

I'd like a blue raspberry slushie...how much?

I've not used one before on the main coolant system of a car, but I have used them in aftermarket A2W Supercharger Aftercoolers. They are a key element in achieving maximum efficiency in them. I've been surprised by the supercharger manufacturers for this chassis overlooking that detail.

It would definitely be interesting see how incorporating one might affect the stability of temps in our car.
@VeloxEric any thoughts on this?

Swirl pots are generally used when there is no other easy place to fill the car from. Sometimes on cars, the radiator, hoses, etc all are lower than the engine and leave few places to fill the cooling system from while getting all the air out. Enter a swirl pot, which can grab a pressure and suction from anywhere in the system (typically pressure from the head or a high point) and allows the system to "burp" itself from air.

Is a swirl pot a superior system to non-swirl pot. Yes... slightly. Swirl pots typically see less pressure spikes than caps placed directly on the radiator or hoses (stock configuration for our cars). These pressure spikes can cause the overall system to run at slightly less pressure than designed or "pop off" before desired.

Do I think a swirl pot would benefit our cars? Not enough to matter in my opinion. Our system is easy to bleed out all the air.

Thanks,
Eric

I remember our favorite feature of the swirl pot - the ability to stuff ice cubes into it in between passes

Obviously not something you'd be doing with the main coolant system on the car - but great for charge air temps

Well, yes, I had to use a swirl pot when I was a kid, back in West Virginia, while visiting my cousins (they didn't have indoor plumbing).

Did they not have indoor plumbing, or was this before it was invented?

So from what I can gather, the swirl pot can help with self-bleeding the system should you develop any hot spots that could boil coolant and create an air pocket.

If that happens or it is difficult to bleed the system, it should help.

Is there increased potential for coolant aerating with a swirl pot if the level dips a bit too low?

Oh, I'm sorry. How does it feel to finally use electricity and this new thing called the internet.

No, its design removes the air bubbles and cavitation. But if it were to run low, there would be other problems.

Yep, this indoor plumbing is really neat. Going out to the outhouse in the winter was a chilling experience. In the summer it was the spiders and the smell that wasn't pleasant.

The electricity is nice ..... I tired of filling the coal oil lamps.

Internet .. ?? Is that what this dial up plug hooks up to ......

It seems that since we have the cap off the rad, and up a bit, the difference would be very minimal, and a proper fill/bleed would be about as effective, (close enough to not make a difference.)

In my GD Subie it has an expansion tank up top which seems to be another step closer to a swirl pot.
