Ok so the temps in the 6 are not what I'd like them to be. Could it be tuning maybe, but the 2.4 is running pretty good and the WB says I'm on the rich side.
I purchased a Mocal t stat. I had already purchased a stock 911 one, but it's bulky so I think I'll sell it. Why do some run the lines up the passenger and some up the driver? Is it because the cooler up front only goes one-way? Just preference? Where is the best mounting spot? Pics would be helpful. Andy put his inside the chassis. I'm looking for a more general mounting spot. Can it be installed up in the frunk as I have seen on others? What's the drawback there? Thanks and sorry in advance for the millionth ask. I might do something similar to tomeric, but was just curious about these other things first. |

I'm going to tell you a long story as quickly as I can.
Early in my career I was responsible for customer attributes. One that was created: Gauges shall display at mid scale at normal operating temperatures (old attribute - pre dated me) Gauges shall be linear (I added this thinking I was being smart) Electrical / instrumentation argued with me that I shouldn't add the 2nd attribute. Being youthful and a racer, I was tired of seeing gauges with a large dead band that made them largely idiot lights. I fought for the attribute and they begrudgingly agreed but with a warning of "don't say we didn't warn you -- you own this". Shortly after launch we started getting significant warranty for engine overheating. Why? Turns out that customers were seeing the thermostat opening and closing. When the thermostat would close, the gauge would creep up (subtle . . . but easily noticeable). When the thermostat would open the gauge would drop back down. Turns out I was wrong (not the first time - not the last). . . . most customers can't handle a linear gauge without freaking out and visiting the dealer. After the first model year, a dead band was added and I revised the specification to remove the linearity. Now take a look at these gauge calibrations and you tell me where you think Porsche engineers DESIGNED the engine to run and whether the calibrations are linear. Now also ask why early 911's had numbers but later 911's (and 914's) didn't have numbers. |

I disagree that 180 is the right temp as you mentioned. I run a pretty hot 2.4 engine (hot meaning not stock) and do not run and engine cooler just 1 in the front. I did this as a way to try out some of my new designs and products. it works very well for me and would support a much larger engine. Now if doing another build I would probably just do what Perry did if at all for this engine. Specifically Nick. My suggestion would be to add a small cooler either in the right side wheel well like Perry did or just a small one by the transmission. That will be sufficient for your needs. I think with the mag cases everyone gets real nervous about head studs pulling. |
