160 Thermostat on order!

[j.fro]

I bought the t-stat from jmatta. I wanted to get a cheap t-stat that I could do a little work with. When I used to drag race Chevies, one of the tricks we had for cooling was to drill a couple of small holes in the plate that opens and closes. This does two things. First, it gets a little coolant flowing before the t-stat opens. Second, when the t-stat is open, it provides a bit more flow.
So, I've done this with the used t-stat. Here's what I'm seeing:
Once the car gets up to temperature (which does take longer now), the average running temp shows lower than before. Before, my gauge read anywhere from straight up vertical to the far right side of the "0" in the "180". Now, on the highway, the temp stays on the hash mark under the 180. In town, the needle will move over to split the "8" and the "0", but I have yet to see it go as far as it did before. Once I get moving, the needle will move back to the left of vertical. This may be due in some part to a modification I made to the center radiator. I've put GT3 RS type openings in front of the hood, moved the radiator forward about 1", and routed all of the air through the center radiator to exit through the RS ducts, over the car.
My biggest reason for experimenting with the t-stat was the cost of the LN model. I trust their data on the value of a cooler running engine, but when 944, Audi, Benz, etc low temp t-stats are $30-40, the cost of the LN model is a bit high.

I installed this 160 T-Stat on my 3.6 Boxster couple weeks ago and i love it, car feels like it runs faster and it more responsive!

The high cost comes from having to purchase a complete factory housing & gasket which includes a stock thermostat that we throw away. We then have made up in small runs due to cost, a quality low temp thermostat to fit the factory housing, made in Germany. We didn't want to skimp on something like this.

Not to cut into your business, but I thought that maybe there was a VW, Audi, or Benz 160 T-stat that would swap right in. No such luck?
By the way, any thoughts on my mod?
2000 986S, 125,000 miles w/ 3 seasons of AX, headers, intake w/dryflow filter, gutted cats, modified muffler.

Nope, I tried that first. No such luck on finding something else out there that would work.

I've toyed with the idea of drilling the low temp one as well in warmer weather, at least in our track car, to see how it performs, but in cold weather that mod will throw a code as the engine doesn't warm up fast enough. If the temperature drops below 160F after warmup, it probably will throw a code as well, or at least with OBD2 it should.

Glad to see my used t-stat found a purpose in life, rather than sitting on my shelf forever. I've sold all sorts of 911 and 986 parts on eBay, usually very cheap. I'd rather someone use them, than have them sit around gathering dust.

Thanks again, j.fro...
