When I went to see Lidio for my tune last spring he had mentioned that the 20" wheels and the 4:10 gears would show less RWHP numbers but I didn't care as long as the numbers were there on the time slip is all that matters. My last tune was done on the street only it didn't even go near a dyno, that's the future my friends and it's here plus the 6R80 and 10R80 can only be tuned on the street..
My Grand Prix was tuned on the street....in 2008! Thats nothing new lolQuote:

That’s interesting. I wonder though how fast the turn around was though between pulls. Cooler engine on the first pull versus a heat soaked engine on the second. I know my car (‘09) loses some power if it gets too hot. I’m not doubting that there is a difference with the two wheel weights but I am wondering if all factors were similar going into the second pull.
If they drove the car to the dyno then it was already hot for the first pull. We don’t know every detail so if we just look at the wheels as the only change, then yes there was quite a drop in power.Quote:

This was one of the factors in helping me decide to stay with a 19” setup (that is lighter than stock). Unsprung weight is the enemy if you are looking for performance (especially if you like to road course).
There a reason Ford uses 19” on its current s550 and s197 top performers (I.e Gt350, boss 302, performance pack cars, etc...)
Interesting yes but slightly misleading. Inertia dyno will show a large change in Whp with heavier/lighter wheels however a load based dyno will not show a change at all or much lower of a change. Since inertia dynos seem to be more common for bragging rights throw on a set of ultra light wheels. Won't change how much power your engine produces though.

All I know is once I changed my factories to forgestar car felt better, hp or placebo I don’t know lolQuote:
