You should add DA & a comment section on your chart for comparisons from pass to pass & any changes that you make.

I launch at about 1000-1200.
Have never tried launch control.
I have tried leaving higher rpm but it doesn't improve my times.🤷‍♂️

Keep on trying things. You will find what works best for you.

Added the DA, really cool tool online at https://airdensityonline.com that I'll have to sync.

Not enough air in the tire I'd say. Mine do not move.

I usually do 20PSI to start the day, I usually don't mess with it. What PSI do you run to start your day?

Find your best tire pressure and try to run with the same pressure each run

I run at 22 psi since I did the 2.85 pulley & tires still move on the wheel. Stock boost I would run 24 psi & tires moved a little.

Good deal, adding the DA, I also have temp & humidity on my hand written chart. Humidity is one of the biggest factors for good ET's & DA is a # of all the factors together.

I run the max the track will hold which is between 18 and 22 usually. I'm running the Weld wheel which might have some grip on the tire, not sure. The slicks used to move and I ran them 15 to 18. The MTs don't move at all so far.

Street Fighter - Hellcat edition. The reason I added the Street Figther effects for this was the dude called me out and said I didn't have a stock Hellcat after our first run. That's okay we ran it again and I showed him the GapFather, GapSon and the GapHolyGhost. He said he'll be back from Philly with work done and that it won't matter how good I tree him. That's okay, my PCM arrives on Tuesday and I'm looking potentially talking to OST Dyno about a package. Enjoy!

I didn't loose sight of cutting a better tree but I'm learning that Launch Control (LC) has it's place. LC is great for bracket racing, consistent launches if you can figure out the tree (.2xx and .1xx when leaving on the third yellow, might have to leave when the second bulb goes out) but I think mastering the memphis shuffle is going to get me better trap speeds. I don't get it though cause at Cecil I was cutting .0X trees. But the best part is, more toys on the way!

Good Passes, what was your ET's & 60' ?
And your using LC ?

 

[fumanchu182]

The ET and 60ft line up with the data from Cecil. 11.1x is the norm for LC. 20psi rear, 85psi in fronts. I have to move my excel onto my one drive so I can edit anywhere.

DA looked to be around 1500 but lots of humidity

DA was 1807ft and Humidity was 100%.

 

[fumanchu182]

Forgot to review the logs. Looks like in a few places Tq is dropping off. Correlated items are Inj duty cycle hitting close to 100%, spark dropping. Wonder what the culprit is.

 

[vortecd]

Yeah humidity will actually make that DA much worse then what it shows. For me drag racing season is very short cause I'm looking for great DA so it limits me to spring and fall and we loose half the days because of bad weather, rain/snow

I was using the dragtimes DA tracker which seems to be pretty close in my area. I bought a Kestrel 5100 to compare it at the track but it real close at the house. Seems every online DA tracker gives you different numbers

-1424 DA are you kidding! I see B Mason in Texas going out with -1000 DA and better all the time in the cooler months. Best I have seen in Michigan in the last few years is -500.
