Question about Rim Size -VS- HP loss It wont be long before I get my car dynoed again and when I did the 1st time, It put down 339 rwhp & 350 rwtq w/ an underdrive pulley and a catback system.
Now, Its about to have on an LS7 clutch & some Kooks headers. So I'm going to take it to see what it'll put down. One thing I've been thinking though is the 1st time I had it dynoed, I had on the stock 16" T/A rims. Now, I have on some 17x11" ZR1s. Will this make a noticable difference on the dyno? And if so, any idea about how much?

If you dynoed after only changing the wheels you would definitely see a difference. More unsprung weight = horsepower loss. If you really want to see how much you gain with the mods, dyno with the 16's.
