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)

Mitch sent me links to some old photos of the LGM radiator install. It looks like at a minimum one needs to cut off the left and right sides of the upper radiator mount and re-use the bolt holes for brackets. Mitch indicated that at that time a thermostat wasn't included.

Since Improved Racing is local to me, I may ask the owner if he can meet me at a lift with one of the Mocal block adapters, and we can directly see if it'll fit without me having to buy and possibly return it. They don't have a shop nor do they install their products. I won't use a sandwich adapter and risk breaking off the filter.

I always felt that local shops didn't truly know what they were recommending with the 160* thermostat. The reasoning was always "get the coolant flowing through the radiator as soon as possible". Another shop, since out of business, recommended a higher temp closer to the OEM stat for fuel economy and burning any water residue out. Tuners don't seem to have a common theory on where to have each fan turn on/off either.

Hard to say if the Canton remote filter adapter works, the 90* rotation may offer the needed flexibility. Where are you placing the remote filter?
