hey dr good u noticed this thread..
ok so in saying the above, lets just assume for a moment i have a wrx that has 180kw engine. now lets say i put it on the dyno with standard 17 inch wheels as per the factory and do a dyno. next i put on my mates 19 inch wheels - same car, same dyno, same day, same everything.
so what if i had 160kw at the wheels on the 17inch run. are you saying that with the 19inch run i will get 170kw (or 150kw)...? is the difference going to be that big??
what that means is that the car owner of any car can get a higher power by just changing the wheels on a dyno day..?
thats what is implied above?
or am i reading wrong?
