Cold air THRILLS
1 Attachment(s)
Ah, its been said before (about this time of year), but dayam what a thrill these cars are in the cold air - not that they aren't in warm air too, but wow what a difference temperatures make!
Ami and I took our toys to the gas station to top off the tanks before their winter naps (less room for condensation if the tank is FULL, doanchaknow). A couple of Vettes firing up with their 3" exhausts and SW headers (sans cats) at the fuel islands froze the foot traffic and got some stares and even a :thumbsup:. Then rolling out together and together "gently" hitting it just a touch (well heck...ya gotta get up to match the speed of street traffic, right?) the full throated reverb between buildings of a pair of growling LT5s flooded the air "a bit". And, if that wasn't enough, the rpm of both Vettes announced just the least bit of tire slippage as they slipped into the flow of traffic. Ah, winter. Hated to have to park em again - especially after such little use this season (due to that "COVID" thing). Dayam! . |

Re: Cold air THRILLS
I couldnt agree more! I know I've posted on this same subject before... when the outside air is between 40- 60 degrees, look out!!! One better have her pointed straight, before any right pedal fun. If the roads are clear ( no salt or snow) i get my Z out for a week every month to drive to work. When she sits for more than 2 weeks I get itchy lol..... But anywho, the car does feel quicker sucking that cold air in. Once the car gets up to temps, its snappy. Its still that way in the summer, but I can notice a little heat soak that isnt there in cold temps. And I'm stock, i cant imagine the glorious sound of your Beasts on a cold start!!

True, they seem to run better...
But, it's just cold tires! 😀 |
Re: Cold air THRILLS
Picking up my 90 ZR-1 with 13,000 miles from Mark Haibecks shop tomorrow morning. He just did a 510 engine pakage and coil over spring suspension. Driving from Chicago to Fort Wayne In., whether suppose to be dry with high temp. of 35 degrees. I suspect I'll notice a big performance difference and I'll be careful. Jim

Re: Cold air THRILLS
I'm wondering with the new technology in vettes today if temp affects them the way it affects our cars...
I was at Ron Fellows school a few years ago in March...I had a 15 Z51 manual...Temps were good, mid 60's windows up AC on....Even with the AC on this car was a monster on the track.. I know the C7Z06 supposedly suffers from heat stroke....At least this is what I hear....I'm just guessing technology has come along way since the 90's that the newer performance cars perform better even if conditions are not ideal... Of course though an engine is basically just an air pump...The better the air, the better they feel.. |
Re: Cold air THRILLS
I would say yes. The cooler the temperature, the more horsepower is created. 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!

Re: Cold air THRILLS
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..:thumbsup:

Re: Cold air THRILLS
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.

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. |
Re: Cold air THRILLS
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.

Detailing the engine compartment and running gear. Remove the wheels and clean the inside of the rims! That?ll keep you busy until the Daffodils bloom![emoji108] Sent from my iPhone using ZR-1 Net Registry |

Moved there three times. I now live close to my kids in NC. No snow in this part of NC, so I can drive all year long. It does get cold on occasion, but once the temps go above 45F the tires work. Sent from my iPhone using ZR-1 Net Registry |

I remember the day, i picked my car (1990 #74) up from Haibeck, after I had the 500 hp package. I was driving from, Chicago to an hour west of St. Louis, Mo. Innsbrook (God's Country) :) any hoo..Marc explained to drive at different speeds, on the way back, to help break in the motor, so i drove 60 and 70 and 80. You are gonna love the noticeable difference. |
Re: Cold air THRILLS
I just got back from a early morning drive out towards Death Valley there is a 4 mile straight away that is at sea level . Man is it fun going to about 120 in. Old air at sea level . Going to make the rest of the day dull lol

Re: Cold air THRILLS
Had to run for materials about 25 miles from my house on New Years Day. This car has 82,000 miles, started red I believe from the factory, then black, now yellow. With that much paint I figured it could handle WI winter roads!

Re: Cold air THRILLS
Was out today in SW WI with a high of 21 degrees and bumped into another Crazy Cat! Turned out he is my summer companion, but who expects to bump into another ?C4? Corvette on Jan. 10th in Wisconsin. Had to take a few shots.

Re: Cold air THRILLS
Let's see.. my winter list:
- Detail under hood (complete except for a-arms and knuckle) - replace Wheel Well seals - Replace A pillar weather strip - Swap LCD panel in Cluster All Above are done - Add the coolant lines like Phil Wasinger did, waiting on gaskets - Swap Cargo Shade (not needed so if I get to it) that is it |
