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. |

Ok so it sounds like the lower flaps could help in cooling. Let me take it for a hard drive and once up to full operating temp 210 I'll open it up to 6k and see where my pressure is at. I have a feeling it will be around 4bar which is fine. The question is then will the temp continue to rise? At what point do I need to shut her down to not cause damage to the engine? 250 260?
As far as the blue print of the engine it is a complete unknown except for the leak down numbers being almost 0 across all 6 cylinders. So I know that it is healthy. It also looks as though it was rebuilt at some time as the cooling tin is shiny plated. Another unknown is this engine could have possibly been suped up with different cams or even displacement bumped up to 2.5 per the PO. |

The question is then will the temp continue to rise? At what point do I need to shut her down to not cause damage to the engine? 250 260? Things will eventually come to an equilibrium. People gonna hate on me . . . but . . . . 240-250 is certainly not out of reason. Personally, as you work your way through this I'd be more concerned with rate of increase. 240 and steady . . . no concern. 240 and still rising rapidly . . . then I'd back off to light load but high rpm to keep air flowing and cool things down. |

With this in mind I will track how fast it goes up. I would say it did not increase quickly. I think it increased faster on the highway vs back roads which makes sense. It also went back down once I was off the highway, back to 210. 45 minutes drive |
