Thanks to a project at work I was invited down to Wakefield Park on Saturday to participate in a Supersprint held by OzMazda.com.au. It was attended by their internet forum and a few other Japanese Domestic Market (JDM) enthusiast forums. Entrants brought cars from Sydney and Melbourne.
The fastest cars were some very trick Nissan 200SXs doing 1:07 and 1:08. Then there were 3 Evo9s in the 1:08 and 109s. Then there was a mix of 200SX, 350Z, Evos, a S2000, VW beetle, Skyline, more 350z, MX5s, MX6s, etc.
I ended up 21st with a PB of 1:14.6 out of 53 modern cars. It was also one of the best track days I've been to. It was exceptionally well run. The cars were well presented and modified and the people were very friendly.
I overcame the oil breather issues from Eastern Creek and the last Wakefield Park sprint. They were caused by the new aluminium oil filler not having enough crankcase breathing. The stock filler had breathing from the half inch breather tube, and from the road tube. Without the road tube, the drain that goes from the filler and down near the dip stick, the aftermarket piece has half the breathing. The solution was to tap an extra fitting in the breather box and connect it to another fitting tapped into the alternator stand.
The Yokohama ADVAN A050s R-spec tyres didn't get super hot, being winter at Wakefield park, but they are grippy right from the first lap and make the car really easy to drive. I love them.
Also check out the new 2.5 inch muffler welded up by Beau at Westside Mufflers Padstow and coated by hi Octane Coatings Rydalmere. My old exhaust was an embarassment. I couldn't use any off-the shelf mufflers due to lack of ground clearance. So The new one is tucked up nicely and mounts to a great looking bracket which bolts to the bumper brackets. The beetle was apparently the best sounding car at the track day. I think the exhaust has also helped the mid range. I had to pull 4th up the hill and down it. I'm not sure it was faster though.
