12.5 to 15lbs depending on the track conditions. If you are running the 1/4
I would start a little high and see if you can hook without spinning. The lower the tire pressure the more the car will sway on the top end.

I have a 28X eleven and a half(my one button stopped working) I trying to get my 60ft down but the best I've been able to do so far is a one.34 60ft. The car has a 4 link system on it so I think it should be able to do better than that. What would you recommend. Here is a vid and you can see some of the launches. I was told I should lengthen my instant center, what do you think?

What's the instant center at now?
What's the pinion angle at?
What's the weight distribution?
How high are the wheelie bars off the ground?
It looks like it unloads the tire, just kind of pops up the front end some and comes right back down to me.
I would list or find these things out before you change anything, you need a starting point to know where you're at and where you need t go.
As far as tire pressure, every car and tire size is different, most people lower the psi till they get the best 60ft without losing mph.
Is your car an auto? Have you tried running a drag radial? The drag radial tire compound is actually softer than most of the slicks that size.
