If you have the Torsen differential, then friction modifier is not required. It quiets down the differential, but does not help with how the differential functions. I am using Red Line 75W140NS, which is the version without friction modifier. I run the higher weight oil and no friction modifier...
If it’s like most events I go to, there is usually time between sessions to leave the track and fill up at a local gas station if you want to avoid paying crazy prices at the track. Have fun!
I use about 18 gallons per hour on track running 93. The tank is 16 gallons, and you really don’t want to get it much below 1/4 tank. If there are long left hand sweepers you can have fuel starvation if you have less than half a tank with the stock fuel pump.
2 twenty minute sessions is the...
Here's my take on the whole recall and Ford quality gripes.
1. Our (myself included) perspective is skewed by our personal experience. If I get a car with a ton of problems and recalls, my perception is going to be that the quality of the brand is awful. If I get a car with no problems...
LOL. I've already signed up for notification when it's available. However, I am most likely going to take the leap to coilovers, which would make this unnecessary. We'll see. :crackup:
The seat belt system has a pretensioner system with a pyrotechnic charge that ignites in the event of an accident. That is tied into the vehicle's computer, so if it is disconnected I expect you will receive a warning on the restraint system and you will be giving up the safety feature of the...
Update from days 2 & 3 at Road Atlanta. More of the same thing I saw on day 1, although the high oil temperature from both days was 276 where I hit 280 on Friday. Temps via the AEM gauge and inferred reading on the dash were about as close as you could hope for. I never saw more than a 5...
1. As far as I have found, there is only the temp bar on the dash, which I assume is displaying coolant temp. There is no detailed readout. I’ve heard people say there is only a cylinder head temperature probe and the coolant temperature is inferred. However the repair guide refers to an engine...
Coolant temps are shown to be reduced by 26 degrees when running water wetter per specs. I’ve not really monitored CHT previously, so I don’t have anything to compare with for the current temps. I’ve never had the car go into limp mode due to high CHT.
I imagine you could loop the coolant lines...
The transmission fluid and coolant flow into the heat exchanger in the front of the transmission. Water Wetter with distilled water gives about a 26 degree drop versus a 50/50 coolant mix. With the water temp lower flowing into the heat exchanger it should also reduce the transmission fluid temp.
Funny you should ask. I was considering posting after today’s track sessions at Road Atlanta. Highest transmission temperature I saw today was 210. On my trip in June/July to VIR, Watkins Glen and Summit Point trip I think the highest I saw was 221.
I’m thinking the lower temperatures I saw...
Results from today’s track sessions at Road Atlanta. This is with Red Line 5w-50.
Session 1. Forgot to make notes and can’t remember exact temps.
Session 2. Ambient Temp: 84 degrees. Observed high oil temp while driving per AEM gauge was 267 with inferred temperature showing 264. High oil...
