I took my daily driver to a little road race practice course today. Each lap was only a minute and I'd stay out there for only 5-10 minutes. The first session I just wanted to work on tire temps, then I let it cool down. I actually logged the second session and have some questions.

Water temp: I live in Florida, so I run 100% distilled water with maybe 1-2 bottles of water wetter. After 7 laps, I noticed the coolant temp was at the 3/4 mark so I brought the car in. The scan tool later revealed the temp had peaked at 244*. Isn't that a bit warm? Solutions?

Brakes: In the front I have standard C6 calipers, Trackbrackets, DTC-30 pads, new standard C6 rotors. In the rear I have Powerslot rotors and HPS pads. All stainless lines and using SRF fluid. While it didn't have a problem stopping, the pedal became easier to depress and started grabbing hard closer to the floor. I didn't like the feel of this, how do I remedy it?

The log also shows it was pulling 4* of timing on all WOT sections. I bet I have a knock sensor code (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif)

More feedback from Improved Racing regarding the oil cooling and the high oil level:

The 3/8” NPT port would definitely be the restriction in your system, and having that restriction would result in a larger oil pressure drop. The ports on the pan are 12mm, or 0.47”. So -8AN or -10AN all around would be best. If you have 5 feet of -10AN line, for example, there would be a 0.5 PSI drop in your oil pressure through the lines. With 3/8” lines, the pressure drop would be 7.5 PSI. However if your lines are -10AN and you just have those two ports that are 3/8”, the pressure drop won’t be that significant.

As far as the oil level, you brought up a good point. It takes a lot longer to drain the oil with our baffle installed. You should let it drain for about 20 minutes, until oil stops dripping out. Otherwise, there will still be some oil trapped inside the baffle. Maybe this is what happened with your last oil change. You may have ended up with around 7 or more quarts in there. That said, it is a good idea to overfill the sump by as much as 1 quart when you’re tracking your car, however. Also, when you have too much oil, you will typically see some blue smoke coming out of your exhaust as that excess oil gets burned off. I never saw any smoke coming from your car at the Gainesville road course, so even though you may have overfilled the sump, it was probably okay.

So my thoughts at this point are that the baffle significantly slowed the oil draining process and nobody knew to allow more time to get all of it out. So I bet I have at least 7 quarts in the pan now. The owner was at the same event, as well as my friend Jeff(94TA). While I'm happy I wasn't spewing oil out the exhaust, shouldn't it have been doing so?
