G´day,
Quickest lap of this trip. A lot thanks to a almost free track on an event organized by Ringweekends, Destination Nurburgring Ringmeisters Prime! Great event in every single way.
There isn´t "soooo" much done since 2017, the significant things;
- More track time for both the car & myself
- 245/40 17 track tyres, road legal, on 17x9.
- Approx 10kg lighter
- New exhaust with catalytic converter (w/o cat before) & CAI. Propbably similar power as before, didn´t measure old setup.
- Had to fit a dB-insert due to having 134db (Titanium) and I´ve dyno-measured losses to 1,9hp with the insert fitted :-(.
- Rev limit increased to 8000rpm. 8000rpm? On a stock engine? Yes, that is to avoid shifting a few seconds before braking. The car is actually loosing a significant amount of power at those revs compared to peak power at approx 6900-7000rpm. However, it is still quicker than shifting to the next gear, driving for a second or two, braking, just to find yourself changing back to the same gear again + the extra hustle and balance/momentum/harmony disturbance.
The car, a Mazda MX-5 NC 2,0 Sport Roadster Coupé 2007.
