I previously asked you guys about how often your changing fluids, thanks for all the replies.
After two years of track events, notes as follow:
First year, after 3 track days, engine oil was slightly dark.
Second year, after 3 track days, including cooking my oil to 120-130C on one or two laps, the oil was straight up black.
Swapped other fluids before this years track days:
Trans fluid was clean, almost good as new in color. (Car had 24,000kms)
Rear diff was underfilled from factory, 2L, refilled with 3L, seems to be a common issue based by C7 forums. Fluid was a shiny/dark grey, seems to be normal.
Brake fluid, no change in color.
Other notes, 3 track days each year:
I ran powerstop track day pads (front only)130$, on year 1, went through about 50%. (Noob track driver)
I ran XP12 front 350$ + rear 350$ on year 2, went through about 60%F/20%R. (Less noob track driver, WAY more aggressive braking)
Lastly, improvement numbers:
Mission:
1:21.5> 1:17.1
Ridge:
2:02.7 > 1.57.7
Vimc and A27 only have one track day.
My biggest issues driving a C7 on tracks:
1. Front tires simply cant keep up around corners, understeer,
probably user error. I find alot of 200hp cars, even newer drivers, easily keep up with me, even gain time around corners, where as all my time is made up on straights / long curved straights.
as expect with 2x the HP...
2. Driving a 5k shitbox, you dont really care if you put it into a wall, cant say the same when 70k is on the line.
3. Goes with the above, i have a hard time keeping the gas pedal down around certain corners at high speeds, for the fear of wiping out.
Now i want to take a 5k shitbox to the track, and see how my times would compare.
Fuel economy:
Turns out my gauge maxes out at 39.9L/100km. My actual fuel economy at mission was 50L/100km, and i think 40-45L/100 at ridge/A27
My bank account hurts, the car kept up, another great summer.
