Sounds sensible. I have to admit I'm as guilty as the next person - I have to stop and remind myself every so often of what I said earlier! This is from the guy who's had (amongst many others) a Mini '1000 HLE' with a Lightened, Balanced, Big Valve head & 285 Cam 95+BHP 1275 and a 180BHP (L.A.D./ECOSSE) 106 GTI... I was perectly happy for over two years with my 2001 COOPER (although I added a Magnex system) and sincerely promised everybody in 2003 that I “Wasn't going to do ANYTHING” to the 'S'. Maybe we should set up "Tuners Anonymous"! Plus the fact I could buy a cracking wee "Classic" Mini for the money I'd spend on tuning the big one.
Speaking of traction/wheelspin - the other day on the way to work, I pulled out (traction control off) to overtake a (much) slower car and basically just wheelspun all the way past it in 2nd and well into 3rd as the road was so greasy - must have scared the crap out of the other car, I felt like going back to apologise. Sounded good though, and the car pulled nice and straight.
It's always tempting to go for a higher state of tune, there's so much stuf available. My fave 'Pipe Dream' is either the 'MED/PROTEK' 240+ish BHP (Big Valve Head, Cam, Pulley, Induction, Intercooler etc etc) conversion, or the 'West Tune' (based at Thruxton circuit) 245BHP upgrade (same sort of mods). Both are meant to be excellent and I'd also save a bit as I already have the Manifold & System. I've managed not to do it for the above reasons...so far.
However, I would recommend a good Manifold (Playmini, Milltek etc) for your Works. It would let all that good gear 'up front' breathe properly, and it sounds the business... Go on, you know you want to... DO IT! DO IT! DO IT! (Runs cackling with evil laughter into the distance).
