Made it out to BW on Saturday the 18th with Speed District. Great event, only 25 cars so there was plenty of open track in each session, mostly m3's and Porsche's but there was a McLaren MP4-12C running around too.
I spent time since the last trackday (ordeal) to fix most of the small issues I had. First on the list was the pissing coolant everywhere problem. Apparently the OEM hose clamps didn't seal tight enough over the silicon because of a difference in wall thickness. It was a dumb mistake and it pretty much ruined the day just figuring out where the hell the water was coming from.
To fix this I ended up getting some industrial grade automotive T-bolt clamps and swapped every single connection. much more sturdy now. total PITA getting the correct size clamps though.
Another problem I had was I was losing cooling efficiency on the oil cooler because the ducting had started to sag around the exchanger after it had been heat cycled a couple times. This had caused a 1/4 to 1/2 inch gap to open on the top and bottom and ruin any efficiency the ram ducting had. I built a sealing frame on the top and bottom to keep this from happening.
Now the temps are back down, i Peaked at 246F after running a 30min session. I can live with that.
Gundan323 also was able to source me a rear Zanardi sway bar to replace the MASSIVE Dali bar and billet clamps I had on there before,
This made all the difference in the world on entry speed, The car is %110 improved and its going to take me some time to adapt to not driving such a loose and twitchy car. Even in the footage you can see how much more relaxed I am over the older set up, granted, not as much fun to watch but its the key ingredient for consistent speed.
At the last event I was also worried i was running too lean with the outta-the-box tune that came with the RDX injector kit. I PM'ed Brian from Prospeed and he was extremely accommodating in finding a time when both our schedules worked to set up dyno time at Bisimoto. After about an hour Brian was satisfied that all the numbers looked solid and that I'd have piece of mind that im not going to melt my pistons on track running too lean. Final counts were 268hp and 205TQ. Heres a quick video of the session i threw together since I always get sounds clip requests for the Sorcery exhaust: http://www.youtube.com/watch?v=EkYCdVTqVSc
The one bummer is my CEL woes for code 22 'front bank spool valve' error. I have now got this CEL intermittently for over a year and cannot for the life of me figure out what the hell is causing it. It doesn't occur when driving the car on the street and didn't happen dyno either. Only seems to happen on track. Ive removed the valve, checked the screens, fine. Removed the valve and bench tested it, fine. Removed the valve replaced the switches electric grease everything. Finally after the last event i bought a brand new OEM replacement for the entire thing, body and sensors, everything. Confident I was finally triumphant I got back on the track and about halfway through the second lap of each session as I start to push the CEL clicks on and the car goes into 'limp' which kills revs past 6400 and shuts off vtec. I was annoyed to see this pop up again since it majorly limits the capability of the car but I just drove around it this time by granny shifting and staying outta vtec. I really have to figure out wtf is going on, ive got one last thing to try and hopefully it will do the trick.
I drove to, on, and from the track on some seeerously raggid tires. they're flat spotted in at least 3 places and are over a year and a half old. I'd ordered replacements but ran out of time and just went with what I had. I realized after the day that one flatspot on the front left had gone straight down to the cords (!!!) and I was still bombing through the riverside sweeper.
YIKES!
Anyways Heres the Video, Theres two laps one is a 2:00 flat (which I was able to do back to back all day) the following one is the 59. The track was really dusty and the regulars were all off pace, im happy now but with a fresh set of rubber and working vtec i think I have a couple more seconds in it at least. For some reason the 2 min mark is a HUGE barrier at BW Ive know people to hover at 2:00:05 for a year no matter what they try.
