Hey Tuners, I finally made it to the track today. It was the first time I've raced my Talon and was hoping to at least break 13's. But I was horribly disappointed with the best run of 15.5. My mods are in profile, but the most important things to note are a 2.0L engine, stock head, small 16g on 20ish PSI (spikes to 22, drops to 20, then falls to ~11 by redline). I also have a South Bend SS TZ clutch (which is part of my issue).

Video of a very similar pass (at least I took down an MR2 ). I was sleeping at the light thanks to the light operator who apparently thought 1 staging light meant I was ready for the tree to drop.

Now, the few things I've noticed that are holding me back:
Junk 60ft times. The Kevlar clutch frickin GRABS. With my composite clutch I had a good inch or two of slip space. The SS TZ? Nope. It seems to be an on/off switch. Not sure if it was because I was a bit nervous, or if it really is a grippy little thing. Anybody have any tips about how to get off the line without bogging with such a clutch?
Atmosphere: I know the air is MUCH thinner at 5800ft than sea level. But thin enough to turn a supposed 13 second car into a mid 15 second car? Everyone there seemed to run really slow compared to the test/tune's I've spectated in California and Mexico.
Boost: This 16g is barely in it's efficiency range and the boost falling off is a real killer of top end power. I feel like if I turn the boost up more it will simply drop off to where it sits now. What can I do to stop this apart from getting a bigger turbo. SMIM, cams, etc?
Any input is very much appreciated. I'm really hoping to bust 13's this year. It seems like it's all there, I'm just missing something. Also, below is a log of the run. Not sure where the knock came from, waiting in line must have heat soaked the car pretty good. And on a side note, I am very impressed with how the car handled the whole adventure. 70+ miles to the track, 4 WOT runs back to back, and then 70+ miles home with zero issues. If only it ran 13's it would be my idea of an excellent street-to-strip car. Overall, the car just seemed a lot slower than on the street and I'm looking to improve that.
