Then you pointed out to me that if I'm not pinging, I'd likely go slower with higher octane. So I stopped putting that octane in. Maybe that has something to do with my temps rising? That's what someone else suggested. It's worth a try checking, now that I'm logging my data more carefully.
Speaking of data, I checked the dates on some of my pictures and it looks like my temp issue actually started before I installed the Qjet, even before I changed intake manifolds (I ran the Holley on the new intake for about a month). I know it definitely got much worse when the Qjet went on last November, but the problem was clearly lurking before. So I must have a few things going on as you said before, Cliff. |
Adam,
What radiator are you running? More importantly how old is it and when was it last PROFESSIONALLY cleaned? A little scale goes a long ways in reducing cooling capacity!
The other question I have is about driving conditions. You state that the real issue shows up after highway driving and disappears once you get off the highway, correct? If it stays cool even in city traffic jams but gets warmer on the highway that is a hint. Under 40mph the fan/fans are in charge, but at highway speeds air feed from the front of the car, ie air dams, grills and such are in charge. Have you mounted a new cooler for the engine or transmission in front of the radiator?
