nah, supercharging is a bit too much, by that point I'm straining the engine, andd would have to upgrade the fuel injectors, pump, cooling... all manner of things, and I'd lose the carbon airbox.
As it is, it's actually fast enough, but not too fast, it pulls nicely, but is a bit on the limit for road use in terms of being sensible, looks like i want it to, and is a nice place to be.
Not sure what the next thing is going to be, other than maintenance. Even though it needs a new radiator as the cooling only works (when aircon is on) at outside temperatures of less than 28 celcius. Mainly as I think after 165000 miles the radiator is probably full of crap so doesn't cool efficiently anymore. But, there's some nice electric overpowered radiators for that, but as summer is almost over, not anything I have to worry about for a good long time.
