When do you consider tack too cold?

treated/unteated. If it matters

Depends on track prep. I do not know how they do it but many here have said they race when it is in lower 40's up North. That is not going to happen here in Texas the way they prep tracks.

From my experience with the Hoosier tires anything under 60* if it was humid gets sketchy. Under 50* with MT and humid. 10* colder than that it is not going to happen. With lower humidity the car may hook better at a little lower temps. Once you get to the Dew Point or real close then you better be real careful no matter what track prep or tire you run.

So to answer your question depends on many variables, Dew point, your car set up, track prep, tire, Humidity and more. I know regardless of what my weather station and data says when I look at the lights over the track and you can see the moisture in the air like fog you better be careful.

You can not just say track temp with out taking into consideration humidity / moisture. They go together and it is usually pretty humid around here.

no track prep for tonight. Temp will be 50 or less. Add in new combo with good amount of power thrown in. Dang pistons had gotten here month earlier would havfe been great.LMAO on getting something on schedule now days.

If had gvbrid on car i would just chaulk it up as learning whatg will work on bad track. With 3:1 compression and 28 ci more. I am thinking I will learn how much one can slide a fed dwon a track.

Brother, you best take everything into consideration before you head to the track.
We all know the itch to put down the first pass on a new combo. IMHO, worst-case conditions are not the best time for that.
The negatives look to stack up in a hurry:
1. No Prep.
2. Cold Temps.
3. (Probable) Humidity if track is in NC, and what Bruce / Curly said above is true.
4. Night-time, adding potential complications with visibility, track conditions, spotting concerns on the new ride, etc.
5. Unlikely to gain much useable data for future racing, in terms of tuning of engine, chassis, etc.
I just don't see much upside, other than possibly some favorable D.A. for attempting a personal best, and scratching the itch.
If track will be holding a T&T on a warmer day or evening in the near future, I would probably wait...

well personal best would depend on in which car. In this one anything will qualify. As for over all doubtful a 3.5- is going to happen.LOL Went 3.61 at 212 1/8 in 1998. So that not even consideration.

Already called two crew guys told them all I will learn is if driver crazy enough to hammer it sideways dwon track, N ot telling replys.

Usually if it's going to be below 45° at night here I'm out but if it's above freezing and the sun is out I'm good. That is on Hoosiers.

Haven't tried the Mickeys in anything extreme except 150° track temps this summer.

biggest issue is. Piedmont when sun goes down. track is in shade for hour or so before. Gates open ten and dark at 7 so track will not have any sun before or during first part of run time. T-N-T they do not treat track unless its big dog night.

Killing me not to go,but gut tells me useles to bad idea. The older I get the more I listen to my gut.

Now at 150 its not rtack temp issue it is where the hell is Chris? answer would be in house or shop with ice cold beer.

Very low humidity where I live and race but it can still get a little chilly, as in 35 at night and 60 during winter days. Still it's nice to have a Grid so dealing with track temperatures is not much of a challenge. Heat during Summer is another issue, 135* - 150* is not uncommon.

Grid is in near future. Had to pick crank trigger or grid and went with crank trigger for two reason.lot less money after bill for pistons and rings. Also figured better to have most accurate timing then control it.

If had grid I would have made few shots using it to see what worked on less than desired track surface.

We ran on a track that was in the 50s last week. Fast cars were starting to have problems.

Hell if fast cars starting to hav e problems my slow junk probably safe best run yet is hi 4.80 and about .1 for where should be.

So maybe make 50 or little under my cut off point till get grid.

0ne of the quickest passes i have made, came back to frost on the seat of my zuma... i was surprised I made it down but I did

Around 2013? at Bracket Finals at Dallas Raceway you ran like a 4.40 and track was so damp and humid many were not able to make it down the track or even off starting line.
