Candy White Golf GTI Ed. 30 - 8th track day at Estoril

The graph looks nice. :happy2:
Fore sure it just pulls and pulls. A bit confused about that difference between power at the engine and at the wheels. :confused:

I'm confused as well. It just feels good when accelerating so I'm not that worried about the numbers. I've done a run 100-200 km/h in 8,2 sec, so the speed is there. :smiley:
teo_parvu:
Then don't worry. That is the right acceleration time, 8.2 is really fast. :jumping: It must be a software error.

The engine likes the octane booster. :signLOL:

Wow, lots of updates :smiley:
IC looks great :happy2:
The reason for the high coast down losses is because of 5th gear. You will also measure less wheel torque at the roller in 5th and 6th. 4th is 1:1 ratio (no gearing at all effectively - 1 crank revolution = 1 road wheel revolution) and will read the most accurate wheel torque, and will also have the least coast down losses. 5th and 6th takes longer to slow the dyno down, hence the high losses. And similarly, you shouldn't dyno a car in 1st, 2nd or 3rd gear because they increase wheel torque, but you would get smaller losses :happy2:
I've never heard of wheel torque being 'too low' for a dyno before, that is strange!
I really would not concern yourself with that stuff. It's just numbers. It's obvious in the driving seat when modifications work :happy2:
