MMMmm, Depends, I have seen several dynos, where the weight and "size" makes a definite difference in wheel HP.
I am not talking 3 lbs but usually when it is over 7lbs per drive axle, you see some wheel HP.
I have some dynos to prove
But you are right, don't expect any gains, but there technically is some HP gained by reducing unsprung weight, such as stock to 8 lb rims.
My buddy with his Integra GSR went from stock wheels to 15" Volk TE 37s and saw the gains I wrote.
I have also seen dynos in SCC, which I pray I still have at home showing this on a Civic DX where there was a loss of 4 HP from going to
17" that were 20lbs heavier up front.
Let me know what you think Texan
