Trackday - Eastern Creek GP

I was lucky enough to attend today's Skylines Australia track day at Sydney Motorsport Park GP circuit. I only managed one session and had a few issues, the overflow bottle was getting full and not draining back into the radiator.

The silicon hose from the throttle body to the turbo BOV looks to have broken either coming off at the bov or getting caught in something so i had to replace it after the first session.
Also had terrible trouble in scrutineering getting pinged for seat belt out of date, extinguisher out of date and no valve caps.

I explained that the date on the harness was a manufacture date and they acknowledged that which as lucky but i had to buy a new extinguisher and pinch the valve caps from the falcon.

Managed to get onto the track and lots of traffic resulted in a best of a 1min 45sec lap.

The drivers door window was blowing out down the straight and then it felt like i was down on power (must have been the vacuum leak from the silicon hose). Then towards the end of the session after coming into put lane i could not get it into gear, the clutch was not engaging so i had to call it a day. It looks like an issue with the clutch fork or pivot as it will go into gear when the car is not running but after the car is running it wont go into gear.

Checked it out when i got home and it is still moving so not sure what the cause might be,

Preparing for trackday

Found a few issues whilst preparing for the trackday on Monday, first was some of the suspension bolts were fairly loose.
First photo is prior and second photo is after tightening, this is on the drivers side

 On the passenger side the bolt had fallen out

Definitely need to do an alignment on the car as i can physically see the toe in and camber differences on the rear and front. 

I changed the oil which i found evidence of fine metal particles, the brake fluid i changed looked a bit worse for wear.

Turbosmart EFR Bypass Valve Replacement TS-023-1261

I replaced the EFR internal bypass valve with the Turbosmart Kompact Shortie - Plumb Back TS-0203-1261.

First thing i noticed was how much better it is made than the simple spring and un-reinforced diaphragm, it is a piston type arrangement and you need to apply a fair bit of force to open.

The Turbosmart internal BOV vents back internally but you can get one that vents to external however i didn't want to have that.

After installing and running in the shed it seems to be all ok, need to get out onto the track and see if it has worked now.
