colder air is more dense and can lead to detonation due to higher dynamic compression ratio (volumetric efficiency increase). add that to your timing advance and that may explain poorer performance in colder air.

EDIT- and you can't actually do math on that unless you know where the weight was added. Was it added in the tires, far away from the point of rotation, or in the spokes, closer to point of rotation? Tire weight would have a lot more impact on rotational mass than wheel weight.

Sorry I was off by a little, Still the added 12lbs of unsprung weight ARE NOT SLOWING ME DOWN 10MPH, thanks.

Maybe it's the weather/clutch slipping/tires spinning/plugs fouled/etc. I'd run it back to back at a DRAG STRIP with both sets of wheels/tires or put it on a dyno. Cars do feel slower after you drive them. If you're not super-confident in your "trap" speeds, I'd contribute it to that.

I remember buying my car stock and thinking "this is the fastest thing ever". Then I put the cam/boltons on and was scared shitless thinking "nothing could be faster than this". Now I have a 530+rwhp 408 stroker and I want to yawn when I mash the throttle.

No possible way your getting oil ON your clutch? Had a nissan beater with a leaky everything and the shudder on a NEW clutch and slip at WOT was retarded. Oil and clutches don't mix.

I dunno what it is right now, First i'm putting my stock rims back on because the 2 rear rims are bent a little bit, then i'll see where to go from there.
