Trackday

Today i managed to get out for the first track day in over 4 years of the car being off the road.

To say i was nervous was an understatement, i didn't
sleep much last night and woke at 4am before leaving for the track at 5am, unloading the car and business going through scrutineering was a bit surreal. When my group was called up i was determined to take it real easy but after the first few laps it just seemed to all come back to me and i started to go a bit quicker finishing with a 1:06.208 second lap.
In the first couple sessions i was quiet worried with the car and in the first session the drivers side brake ducting come loose and a section of it get destroyed.
I also had the dash rpm wrong so it was saying 7000rpm when i was doing 3500 or there abouts which meant i was changing gears by noise.
Also had terrible trouble with the radiator temperature and saw 112 deg C on the radiator exit at a couple of stages, as the temperature gets higher the computer cuts out ignition and over 100 deg C it wont rev past 4000 rpm.

The overflow bottle had a lot of grit in it so i need to flush the cooling system and also look at making up some ducting for the cooler and radiator to hopefully fix the problem. In the build i moved the cooler and also removed the clutch fan and just have a thermo fan. It is reaching the high temps when at full pace so the fan wont really be doing much at that speed anyway i would think.
Had to make some damper adjustment after the rear was very loose, turns out i had one side set to 12 and the other 3.

Also simple things like the seat belt wasn't adjusted and when i did adjust it the lap part of the belt is too high and i need to get a new one with a crotch strap. I ran out of fuel because i hadn't finished off the sensor wiring for the fuel level, seemed to go through 40ltrs of fuel in 4 sessions which is a lot. 

The oil pressure and fuel pressure  sensors were not working as well so i need to fix those.
Was pretty happy to just have these minor issues and see the car do a 1.04.2 lap in the last session.
My PB was a 1.02 (think flat) although a friend mentioned 1.02.2 today so that might be it, not sure.
It would not be difficult to knock a heap more time off with a new set of tyres, an alignment and fixing a few of the issues and it feels as though with the new setup it would do quick laps consistently.
