Nice pics, I was there the same day. I saw your motors, very nice. Unfortunately I didnt have mine with me because its still goin through the legalising process (so far i've been without it 12 weeks). I was there with a mate and his M3.
I have a pic of that GT1 Porsche (Champagne one) spitting four foot long flames out whilst going around the Karussell. If it weren't for it's imminent magazine use, I'd post it on here. May well see if I have a similar one anyway
