I can attest I feel the power difference driving the Z on a cold morning!

I would disagree with the statement that Turbo cars are slower when it is cold. Just the opposite is true. I bought new a 1986 Buick Grand National. Look it up if you don't know it, but with denser air they are stuffing more air and as long as injectors can handle it more gas into the chamber for firing. I don't have any proof, but it use to be said that every 1 degree drop was worth 1 more horsepower in the Turbo Grand National.. Ice on the plenum etc. I can tell you 1st hand that it was faster.
