What am I messing up on during my launch? (video included)
 

Best run I had the other night was a 12.5. I ran again but didn't get a time because it was a red light for a car behind me but the official told me to go anyways. PSI was at 17 for both runs. The car bogs bad both times as you can see, but I swear I didn't let off the gas. Should I launch way higher? Raise PSI? Or both? Tires are MT ET street radials. 60 ft. was 2.01 and mph was 114.7. I don't see any reason why this car can't run 11's.

Launched at 28-2900 this run.

This one was launched at about 4k.

I guess the rpm I left at didn't show up for some reason in the post. Anyways, the first run I left at about 2900 and the second was done at about 4k. I didn't spin at all coming off the line. Mods are 93R tune, LT headers, and O/R x-pipe.

You're bogging because you're not launching high enough. If you're not slipping at 4k, then go higher.

Those are sticky tires. Launch at a higher rpm. You can see better times from a clutch dump but I'm not a fan of that...but if you want the quickest pass possible you will have to drive the car like you hate it.

agreed. Launch at a higher rpm. Maybe get somekind of a Two Step so you can just floor it and with the clutch engaged it will hold a specific RPM. If your not spinning keep going up in RPM until you start to break loose, then go back down to the point with which you were not spinning.

So the PSI isn't to blame? I have no problems launching at 5k. I'm not expert but I'm quite confident I'm losing at least a half a second at the line that's keeping me from 11's. Those are some really sticky tires. I was fooling around with them aired up to 26 psi and they still stuck pretty good. They actually ride quite nice on the highway.

If your bogging, launch higher and slip clutch some more

if your spinning, lower tire pressure, slip clutch ( if it can stand it) lower rpm

If you don't have a problem launching at 5k then just keep launching at that rpm.. That's about right for those tires anyway.. Shouldn't have a problem hitting 11s with your traps.
