I’ve owned several c5’s, but have never had any of them put on a dyno. I have heard just like many of you that the c5’s lose more power through the drive train than the f-bodies. I do believe this to be true. My 98 c5, auto with the performance gear was rated at 345 hp at the fly wheel and my buddies’ 2001 z28 was rated at 310 hp. When we would race he would always pull on me and at the track would always have a few mph’s more than me. The reason I am bringing this up is that I don’t believe things have really changed that much when comparing the new c6 to the 05 GTO to drive train loss. Now I’m not saying that the GTO will beat a c6, but I was wondering how the two dyno compared to each other. They are both rated at the same hp and yes the GTO does out weight it, but it does have better gearing and less drive train loss. Has anyone seen these two cars dynode stock or has any one with these two vehicles raced. My buddy has a 05 c6, but has now put the 1.85 rockers on his car, so I never got a chance to race him stock. We are both autos and I’m curious how close it might have been stock.
