NSW Supersprint Round 4 - Eastern Creek GP CircuitARDC organised this round and it was our first for the 2012 season on the original Eastern Creek layout, with the realignment of turns 6/7. There were 91 drivers entered, including 27 non-championship entrants. The weather forecast was for possible showers, but thankfully it stayed dry all day. Temperatures ranged from 12 to 16°C and there was a lot of cloud cover. Rather than the usual 3 flying laps, we were given 8 minute runs which meant that most got 4 flying laps per run, and a total of up to 5 runs - including a half hour lunch break for the officials. That total of 20 laps is much better than the usual 15 laps, but there's still room for improvement with quite a few delays through the day.
Run 1: 2:03.661, 2:02.363, 2:02.086,
2:01.553. I took it pretty carefully on the first run with the R888s. Started with 23psi cold and they climbed to 30psi. I dropped them back to 28psi after this run.
Run 2: 2:01.743,
2:01.078, 2:03.591, 2:01.251. I followed Peter Browning's Class 3A NA6 on this run. Peter hasn't dríven Eastern Creek for a few years and I kept catching up to him and had to back off on the third lap and give myself some room.
Run 3: 2:01.856, 2:01.019, 2:01.171,
2:00.669. After passing Anthony Crott's NB into turn 2 on the first lap, I had a clear run. Experimented with a few different approaches to the new turn 6, and found a method that worked for me: turning in with a touch of trail braking to get the rear sliding, then cutting the apex and sliding all the way to the start of the south circuit extension. Good fun! I dropped the hot pressures back to 27psi after this run.
Run 4: 2:03.415, 2:01.158, 2:01.020. The first lap was a bit frustrating as I had to overtake an Alfa GTV into turn 2 and then kept catching an XR8 in the corners. So I backed off at the end of lap 1 to give some room. Had a few problems with the rear stepping out a bit too much in the 3rd gear corners. Lap 4 started really well but I was surprised to see a car off in the gravel at turn 1 (no yellow flag!), and I had good speed through turns 2 & 3, but the run was red flagged just as I crested the hill to approach turn 4. Bugger. So I only got 3 laps for this run.
Run 5: 2:01.628, 2:07.704,
2:00.627, 2:01.238. In the last run with the setting sun streaming in under the low clouds, I started last in the group and behind a Porsche 944 Turbo who was doing similar times to me. He let me pass on the straight to begin the first lap, but then frustratingly blasted past on the main straight at the start of lap 2. My speed through turn 1 was badly compromised as a result (words were spoken!). I caught him again by turn 6 so I backed right off to give some room. It worked because my fastest lap of the day came on the next lap. I caught slower cars on the last lap.
Overall, I had a best lap of 2:00.627 which was 1.34s slower than my PB (1:59.288). I reckon I was gaining about half a second in the new turn 6, but lost quite a bit of time in the other corners due to reduced grip from the R888s. We're talking 0.5s in turn 1, 0.4s in turn 2, 0.3s in turn 7, 0.2s in turn 8, and 0.4s in turns 10/11 ... it adds up.
The R888s are starting to come good but are still nowhere near as sticky as the RE55s were at the same stage of their life. I'll be taking them to Phillip Island for the 6hr Regularity Relay on 4th/5th August, and hopefully they'll be well settled for the next Supersprint on 12th August - first try of the new long circuit at Eastern Creek.
I had one interesting experience during the day when the eligibility officer asked to check my car

. Apparently someone reckoned that I had an LSD fitted, which is ineligible for Type 1. My diff is definitely open and I was able to quickly demonstrate it by jacking up the rear. With the engine running and in first gear, it took no effort to stop one rear wheel while the other spun. Then with the engine stopped and out of gear, turning one rear wheel left the other stationary. And lastly, with the engine stopped and in 1st gear, turning one rear wheel caused the other to spin in the reverse direction. Yep, an open diff alright

. Of course I know this full well because I've spent the last few years figuring out how to get decent exit speed from tight corners without uselessly spinning the inside wheel.
I finished 4th in Class 1B behind Alexander Ball's Elise 111R (1:49.044), Tony Chan's Celica (1:57.529), and Glenn Thomas' NB8B (1:59.386), but ahead of four other drivers. In the championship, I'm now 4th in Class 1B and Type 1, with a good chance of finishing 3rd. The MX-5 Club of NSW collected plenty of club points too, with class wins to Ralph Thompson (2B, 1:51.362), Steve Green (3B, 1:52.737) and Peter Browning (3A, 1:59.897), and second places to James Horne (2A, 1:58.308), Russ Maxwell (2B, 1:54.104), and Phil Abraham (3B, 1:53.957). After four rounds, the MX-5 Club has a healthy lead on 401 points, to ARDC (340), and NSWRRC (263).
Natsoft ResultsMy video didn't run out too well this time as I had the spycam misaligned. Got lots of coverage of the cabin and very little of the view ahead.

So I don't think I'll worry about posting any video this time.
