QUOTE(767driver @ Jun 14 2017, 09:53 AM)  QUOTE(ConeDodger @ Jun 13 2017, 11:46 PM) First of all, gauge and sender compatible? Your 4th and 5th gear problem is fan speed. I have confirmed that with CHT. As soon as you go into 5th gear your CHT starts to rise. The rise in oil temp is just the response. I have a front cooler and an incompatible sender. I've confirmed my temps with a pyrometer as much less than the gauge says... Bitch is lying to me! (IMG:style_emoticons/default/av-943.gif) I can drive in 4th gear at 4000rpm which is 70mph in my car. Still gets hot. What's the difference between driving at 4000rpm in 3rd and 4000rpm in 4th? The higher road speed and less air coming through engine compartment due to the 914's aerodynamics. More load on the engine in 4th gear cruising, any thought given to the engine tune? Could it be lean where it runs hot? If its a 4k rpm problem, maybe the main jets are a little undersized? Or maybe you need different emulsion tubes that bring the fuel on quicker. |

Does this 911 make my butt look big? Group: Members Posts: 806 Joined: 23-January 03 From: Lowry Crossing, Texas Member No.: 185 |
I used a Setrab FP920M22 IFeaturing a Setrab ProLine 9-series 20-row cooler (p/n 50-920-7612) and two low-profile 342cfm sealed-motor Spal fans, this unit performs sitting still as if mounted in the direct airflow at 50mph. http://setrabusa.com/products/fanpacks/fp920m22i/index.html
In the rear passenger. We elected to run the fans on a separate switch rather than a heat sensor. The car has never run more than half way up the gauge (911 with no numbers, I added the Naca duct and ran hose directly to the cooler. Its maiden trip was Dallas to Monterey with zero issues. Took it to Santa Fe NM the end of May with the same results. Attached thumbnail(s)
