After about 5 years building this car I finally got it out for a proper track test!
I ran all sessions with no real issues other than being unable to get heat into the (very second hand) tyres so I lacked some grip and stability. Being very careful I managed a best lap of 1:04.57 which is about 2.5 seconds better than my previous best time in a different car.
I'm hoping to get it under a minute at this track, which looks to be very doable and would make it the fastest Nissan "S Chassis"

I got back out to the track last week, and am now the fastest Nissan "S chassis" at Wakefield
Painfully close to a sub minute lap! If I had backed off slightly later it would have just got there.
Unfortunately it was right at the end of the day and I couldn't go for another run. There's a lot more time left in it - mainly in braking. I'm not really right at the cornering limit yet either. Looking at data from a few laps, I could have done a low to mid 59 if I put together a few of the best sectors, so a 58 would be possible I think.

yep, the main problem is the rusty driver now!
Funnily enough, I started the day on low boost (which I've never tried before) and was over the track noise limit. The exhaust has already been designed to minimise noise, especially at that track - so the only option was to go back to high boost No problems then with the wastegate being held closed a bit more!
You can see the boost creep up a bit as I go - which is the closed loop boost control slowly bringing it up to the target value. The base wastegate settings have the boost a bit low because of the ~700m elevation dropping the ambient pressure.

I was invited to run my car at World Time Attack this year, and since I wasn't going to be on my usual international team pit crew this year I figured it was a good opportunity!
The car makes well over a tonne of downforce at the lower elevation and higher speeds of Eastern Creek Raceway, and with the night time running I decided some titanium skid plates and a front splitter camera were necessary
I ended up 5th in the class, and beat some much more serious cars, although I wasn't really happy with the lap times I achieved. I need to get back there and do some more practice instead of turning up 5 years after driving at that track!
