...well my first time at the track and got to run 5 times with my best time being a 14.298s corrected time using the NHRA altitude correction factor ... the actual time was a 15.307 at 5314 feet (Albuquerque, NM). I am actually really happy though because that time was with a 2.497s 60' time, which I know I should be able to drop to at least 2.1 or 2.2 seconds which should allow me to break into the 14s up here which will be 13s at sea level. After doing a long burn out after my first run, my next four runs I was being very cautious with my launches (really just creeping off the line very cautiously). On my best and final run I feathered the clutch at about 2200rpms still being very cautious and got my best 60', but I know that there is still plenty of room for me to be more aggressive (I think the biggest factor was that I was really nervous since it was my first time at the track). Also, I definately miss the LSD now, especially on my 1st-2nd shift, where I am still peeling out quit a bit. I will be back on Sunday and hope to break the 14s up here (I'd be happy even with a 14.999)
You guys weren't kidding when you saind launching on the street and launching at the track are two COMPLETELY different things. Perfect example, I saw a 2003 cobra pull a 15.4 (not corrected) after peeling out all through first and most of second (when I did that I got a 15.9 (not corrected)).
The only other significant event was a Shelby Cobra replica who lost control at the end of the run and hit the wall and spun around about 3 times. Luckily the car didn't flip and the driver was fine ...but the car wasn't. Although he still managed to run a 13.5s corrected time.

 

 

I ran a final (of 4 runs) 14.102 @ 99.46 with my Auto Touring 2 weeks ago here in the Phoenix area. This was at 1,800' altitude. Can you point me to the NHRA formula? Regards, Jim

Knock that 60' down and you should have you a good 13.7 or 13.8 easily on a decent track.
