The Castrol Fit once again went on the Dyno at Trinbago Grassroots Autosports DynoDay #2 (2016). The last two times I dynoed the car, these were the results:
>>>>2025 DynoDay:
74.43whp / 62.95tq
>>>>2026 DynoDay #1:
76.82whp / 72.63tq
My new figures are:
77.55whp/70.05tq
While there is an increase in wheel horsepower, that can be contributed to many factors, mainly air temperature. What I can however conclude is that the engine is effectively running just as good since 2025. Basic maintenance with the right oil (Castrol Edge 10w-30) at the right intervals (every 10,000km) goes a long way.
What's also interesting is the power obtained from the different drive modes. Note that because the car has a CVT transmission, it's not able to hold 1 gear, so the graph is showing wheel horsepower vs speed (NOT RPM).
Sport Mode saw the most wheel horsepower as the speed increased. , but the least torque. Normal mode saw less wheel horsepower, but a big jump in torque. Low Mode however didn't do what I expected it to normally do (lower wheel horsepower, but the most torque). I suspect the transmission began to heat up after making the other runs back to back. This however shows why I am so serious with cooling the transmission between races as the power severely starts to drop off as the transmission temperature rises. So don't laugh when you see me spraying water thru the front grille. It's the transmission cooler in concerned with, not the imaginary intercooler π€£.
