You guys need to get mt drag radials, they hook for me everytime they are awesome. I can launch at off idle to 1500 or even flash it when the track is prepped even though its harder on the drivetrain.

Yeah you were. I really wish that I could have gone more too, because there was a lot left in that launch... I know it. Another .1 at least, which would definitely have me in the 12.3-4 area at least. On my first launch I wasn't very high at all, in the teens somewhere, and then just mashed the gas. That didn't work obviously. The second time I was up in the mid 2000's, but I'm not exactly sure where. I had just crossed ~2100-2200 when i looked up at the lights coming down and I got it a little higher before I launched. MAN I want to get back there and feel it stick off the line though. At like 10-15 when i punched it it REALLY went.

Edit: Oh, and my friend that was watching guessed a burnout of like 8-9 seconds, so I'm not completely sure, but that's what he said. I couldn't really see it very well because there was a pretty good wind blowing blowing the smoke away and keeping it down low.

I traded in my 275s for 315s...which do you have? You know what your altitude is?

I have 275's. The altitude of the track is 667ft, and the DA at the time of my run was just a touch over 2200.

I ran Nittos for two seasons and now run Mickey Thompsons. The M/T hook MUCH better. But I did get some low 1.7 60's out of Nittos. Here is what worked best for me:

19 - 21 psi. No more and no less or I would spin. 10 second burnout. That is to say that as soon as I started to see smoke I would count out ten seconds in my head like 1 mississippi, 2 mississippi, ect. Then stage ASAP so the tires don't get too much time to cool down. Brake stall up to 1500-2000 rpm's and floor it on the third yellow.

Now when my Nittos were new to 50% tread they would dead hook but after 50% they started to spin me out of the hole a little causing me to feather into a full throttle.

Try that the next time you go and see if you can't nail a low 1.7 or high 1.6. You can also go off a dead idle if you want. I got several 1.75 60's doing that.

Awesome, thanks for the advice. I had mine at 35psi still and didn't probably do quite that long of a burnout. And really just got one run... lol. So I know my 1.81 and also the 12.54 can improve. Especially after what you just said .
