Ha ha - No that wasn't me - but I saw that guy. Duncan and I were talking about him - His smoke kept ketting worse and worse and worse until bang.... (That was a GTR)
I was in the Silver R33 GTS-t - Went out first session - did about 4 laps, punted it down the straight, then when I braked/decelarated - massive amounts of white smoke from the exhaust. I think it scared the shit out of the Shane and Ben behind me - he he.
I parked it after that.
Drove home no problems - still makes boost. So I'm pretty sure its a seal in the CHRA. Not a big deal - Just more $$ (which I don't have)
Cheers,
