Tires don?t stick with cold pavement!

Took mine out tonight to check the new LED headlight alignment... 36* outside temps... the LT-5 loves gulping up that cold air alright... feels like I added 25 more hp..

Speaking of getting a bit sideways. Right after I bought my car it had the original tires that were rock hard. Breaking the tires loose at 30 was kind of neat,for a while. Then one day I'm sitting at a light and a car in front of me was stalled,look in the mirror and traffic is barrelin down so I had to make a move. I whip around the stalled car and the tires just spin,I went through the intersection looking out the passenger window,kept it hooked sideways at a comfortable level,tires got some grip and the car slowly straightens out. Never once got sideways stupid,I would have loved to have been sittin at that light to see that.......sorry for the hijack.

According to Chevrolet?s Corvette Racing program manager, Doug Fehan, who told me that Turbo cars have reduced horsepower versus the Corvettes. He was referring to the Ford GT?s. 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.

Yup!

Air volume expands and contracts with heat. Air pressure and volume being equal, there is more O2 molecules in cold temperature air than there is in hot temperature air. Water injection was a top secret "trick" in WW-II fighter aircraft - that and (drum roll plz) intercoolers cooled the air volume. Internal (water injection) and external (supercharging) of the combustion chamber air = more power. Cold air intake and power increase is "for real"! Too bad the friction coefficient of the tires is going the other way of air density as temps drop.

I think my cold air thrills are finally finished for a while here in SW WI. Im standing in the garage full of excitement and then I look outside. I don?t know what I will do with myself for a few weeks. Im sure you all feel the same way in the winter ridden states.

Time to fix and polish!

What if I told you nothing to fix? Marc and Pete are pretty good! Too cold to polish.....dry and tight but cold!

I figured it out!
