[QUOTE="ReplicaR, post: 1457647, member: 9209"] A quick recap of yesterday. Went to the track, and got mechanical flag right in the middle of the first session. I was dropping oil and smoking it, had to come back immediately and investigate. The culprit turned out to be a valve cover gasket on the passenger side, which is a pretty straight forward job, and luckily AutoZone nearby had a set in stock, so after missing one session, I successfully buttoned the car up with my basic small tool set, and ran the rest of the day reliably. The bumper vents helped tremendously, as I was pushing the car really hard, and the water temps never got over 200, with oil getting only to 240. There was still detonation, as I saw wideband get into mid 13s AFR during wide open, so I decided to cut the sessions short. I've noticed that the mixture would change after a few laps in the session, after the car would get hot, so maybe the fuel pump isn't cutting it anymore. Another problem that came back was fuel pressure building up in the fuel tank and me dropping gasoline through the fuel filler cap. That will be fun to diagnose again. The upside to the day was that I ran 1:31.2xx towards the end of the day, when everyone was starting to slow down due to high track temps (faster times usually happen early in the day). It's not too bad considering that I fully cooked the brakes, driving was still a mess because I've never ran this configuration before, and I'm on 5 year old NT01s that might be all cycled out by now. More updates to come soon. Oh and just for [URL='https://www.sn95forums.com/members/tillerman77.21761/']Tillerman77[/URL], the night shot. [IMG]https://i.imgur.com/fwMonXg.jpg[/IMG] [/QUOTE]
