Sorry i missed your post earlier mate. I sent an email asking him and here's what came back;
"The car is not set up properly yet. When i bought the car, it had terrible suspension, with standard brakes and road tyres. I have done about 35 laps in the car in 2 days with that setup to get the feel of it, but on the last weekend (3 weeks ago), the oil pump packed up about 2/3 the way through the 3rd lap. I managed to save it without seizing it, so hopefully won't be too much to fix. Rebuild obviously, but hopefully rods and crank are ok. With that setup, the car would lap the Ring in about 9:20 mins or so on a clear run (never timed it though).
I now have Bilstein Group N suspension, AP Racing big brake kit, new rims and Kumho V700's ordered for it, plus going to fit a cage too as I'm at it. The car should be ready for the season next year, as I'm gonna be away anyway, there's no rush. I reckon the car will be good for about 8:20 ish for a full lap when finished, possibly quicker with a lot more experience on that track. You're gonna have to come over at some stage to see it, and drive it yourself. You'll love it!!"
