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. |

So I was thinking about this while reading up on adding a cooler. I have read both sides where some needed a cooler and some did not for the same size 2.4. I don't believe this engine was getting hot when removed from its last place in a 911. I know the 914 can make any engine run hotter due to less air flow. I will check the timing again, but I was around 5 degrees last I checked.
Things to note. VR1 20W-50 oil I have no firewall pad. I have a GT style engine lid I DO NOT have the air diffuser flaps installed, could install and see All engine seals are new and in place Temps do not get super high ~210 - 220, BUT this is with driving at night with cool 70 degree air or early morning 70 degree air. The SC engine I have might get to 180 in the same conditions. 12 AN fittings/hose for all oil flows. As temps go up my oil pressure suffers a little. At warm I'm around 3 bar at 3k, but when the oil reaches 210 I'm closer to 2 bar at 3k. So while that is still 10 psi per 1k it is definitely not what I want to see. This is what lead me down the path of wanting an additional cooler. Maybe with lower temps the pressure would stay higher. |

If you are seeing 220 at 70 ambient without driving the car hard something isn't right. An external cooler with good air flow will make your oil temps drop but it won't fix whatever is causing this in the first place. (IMG:style_emoticons/default/popcorn[1].gif) |

(IMG:style_emoticons/default/popcorn[1].gif) (IMG:style_emoticons/default/agree.gif) Just one point on "highway speed" which is where you were getting your higher temps. I don't know speed what that means. To some it means 60 mph. To others it is 90 mph. Aero drag goes up as the square of velocity ( Aero Force = constant * V^2). So there is a SIGNIFICANT difference in the load on the engine between those two speeds. Between those two speeds, aero drag will more than double (225% increase). |
