exactly...if your measure of speed is spinning tires. cold tires dont get traction

also cold pavement has the same effect....as in winter wise. so you might have a higher top speed in winter but your 60 foot wil suck as in dragstrip runs.

and das shmoo.....i meant all na cars...you must be running a turbo setup? sorry for not clarifying that. and i take back that comment......most cars have a better torque response when cold...is that better?
