Weather

Tex

That's a great barometer, 29.65 lots of air pressure, to bad it's hot and humid.
Good luck and get the first moparts win of the year!

Very cool, thanks for posting the pics.

Well today is done . And not really successful
Track iffy .
1st qual just spun up when ler button grabbed 2nd still spun . Rolled through for a 15 with 2.76 sixty
More rain
2nd qual spun but went 1.75 for a 10 80
So lost 3/10 in sixty and about 3 1/2 tenths et
No more qualifiers .
Race day tomorrow . Hope after grp 1 tonight and 3 classes before us tomorrow the track might be better . But dial will be a guess
I am #8 of 15 . So #15 is first round , 12.70 car

Tex

Good luck tomorrow Tex. Is Ray Ross the owner of the Valiant charger.

Whew! That humidity would KILL this desert rat!!

Yep
6.30am light rain overnight . Going to try hitting tyre harder . Guessing dial

Tex

I'll have to see if I can find the pic I took of my thermometer / hygrometer showing 90+* F and 95% humidity one Mid-Atlantic August day. It was a total swamp-fest and my car was off at least .3 & 3 MPH from good air.

Days like that you walk out the front door and by the time you get to your car in the driveway, you want to go back inside and take another shower 'cuz you already sweated yourself out.

Pi$$er, but good luck!

I love to run in 4500 ft air with 150 water grains.
Doug

I dont Doug .
Up at 11.00 ish
Track us looking feeling better . Grp1 last night got all the love . Super sedan and top sporstman before us will help .
Bit of a guess

Tex

Come on guys, if the D.A. is not above 4500 Ft with above 100F air temps and around 50+ % humidity you ain't racing in the Mojave desert in the summer time
AKA aside, I've raced in those conditions at LACR and the old Las Vegas track year ago
Las Vegas got smart sooner than LACR and started not opening the front gate until after 4:30PM from May until Sept., first time trial around 7:00 PM and first round after midnight.
I think the new track has a similar summer schedule also, does it?

Well my day went to custard , out in 2nd of 4 rounds .
1st elim was 31/3500da and 103 grains . Looked at yesterday and previous passes .
Ok i am going with 10.50 . Laid on the light for 0.080 , urgh , drove around a Holden v8 ute hard on brakes for a 10.53@117 .
Great i have a number to dial against !
Well that didnt last .
Rnd 2 DA3072 , dial a 10.49 against a tough 10.28
Crap not just a -0.031 but car spins so hard off line there is as much smoke as my burnout ! Literally
Fing hell !
I guess these Hoosier radials are just not working for me . I will have to reasses whether i import a new set of MT PBRs . I know the Hoosier is slower in the sixty than the mt for me .
Unfortunatelly my racing may be done for 6 months or do due to work issues . At least i have some time .

Tex

Why not a stiff wall bias slick?

I've tried both types of slicks and all the drag radials I know of don't work well on marginal tracks, none of them
On your deal with the water, rain, and low amount of runs on the track after the rain I would have put the bias ply tires on went for
The radials on my old car where usually from .1 to .18 quicker and from 1 to 2 MPH faster on the good tracks on my old car

NSSGuy and Cab
In the last 15 years or so i have only ever run crossply slicks once . I have never run them in the Plymouth . I have run the PBR since it came out and never had this spin issue . I havent had the PBR flat spin , yes occasionally scrabble or turn but always drove out .Part of the reason is as my daily when i drive to the track i only need to swap out rear tyres .
Oh well . Sometimes best laid plans dont work .

Tex

Not quite 4500 but still great weather. Lol

Raced at over 4000 here in middle of summer , man does that suck

Tex

I remember seeing 7700 FT DA at LACR in August at 3:30 PM with thunder storms nearby, it was 4400Ft. DA at 10:30 in the morning with clear blue hot skies

Foul

Tex

I’d love to see consistent 4000 ft DA’s, during the summer in Acton, it’s always between 6000 to 7000 ft DA.

I remember a member on here who lived in Phoenix, AZ, he wouldn't race his car from early to mid May to late September do to the heat and humidity there, he was smarter than me
BTW, LACR was in the high desert at 2500 Ft altitude is what I remember, it was in the south west corner of the Antelope Valley near Pear Blossom on the north side of the foot hills of the San Gabriel mountains.

Here in Vegas we would do back flips for a barometer that was 27.90

Here is a facebook link for my class on friday .
We were first out

I guess we only complain when out of our normal DA . I think Sydney is about 240 above sea level , average 1800-2200
I did add some vehicle details to the pics

Tex

But the water grains are what ? 10, lol
Doug

Thanks for the post and the pictures.

Do they hand you an O2 bottle w/ a face mask when you drive through the track entrance?

Only to the low level flatlanders

In the middle of the summer sure are, but we aint racing either. My experience racing back east the last few years in the summer with GOW at 120-140 is that is a LOT easier to deal with than a lack of barometer is. Just throw some timing at it to burn off the water and we loose very little. Take away the barometer and there is nothing we can do to make up for that unfortunately.

I learned something, Thank you Mr G
