My dirty daily mk2 gets the odd trackday hooning. Fully rebuilt 8v, fast Road cam, ported head , compression hike , the usual. I did fit a new oil pump , water pump/stat/senders and oil cooler matrix on the oil filter. According to the mfa, I'm getting 125 or so degrees oil temp on the last outing, after a few laps .I'm no driving God, but I'd be pushing pretty darn hard. Coolant stays slightly left of centre , no smoking etc. Oil temps on the road rarely get to 100 degrees. I'm running 10w40 semi synthetic , not supermarket rubbish. And it gets changed every few thousand miles . Opinions ? I'm considering making it a bit more track focused , stickier tyres, more aggressive suspension etc, so I'll be working the engine harder. .. But I still want to be able to drive it to the Ring for example .
