I just finished cleaning all the inside glass of all my gauges (what a difference they look NEW) So I toke her out in the Miami weather tonight the outside temp was a nice hot 80 degrees. I drove my 914 for over an Hour an Half I drove her really hard and fast up 80MPH:driving: . The OEM temp gauge only read a 1/4 up and it never even got half way up (IMG:style_emoticons/default/piratenanner.gif) . Once I got home I opened the engine lid and the Dip stick Temp Gauge read 250 degrees. ( note i have checked the dip stick boiling point yesturday before i installed it.) If My 914 is running hot what what might be the causes and which gauge should i trust.

Thanks for helping (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/mueba.gif) . I am going to give the car a full tune up next month. I hope this will bring down the temp. I am also going to buy a CHT gauge. Most likely the VDO I know the are not temp compensated but for the price I rather do the math to compensate the temp. I also want to keep my gauges looking the same.

By the time the oil temp is recorded at the high point, it's proably going to be too late to save your engine. The important measurement is the CHT. I purchased a compensating CHT, cylinder probe and wiring for under $100.00 at Aircraft Spruce. In the past couple of months, I find that my oil temp gauge matches up to the CHT gauge reading- after about an hour. As for temp cool down, the oil temp gauge provides no real help. If you're worried about your engine temp, go for the compensating CHT. Eric Read |
