listen it's simple:

your car should not be losing traction like this unless you are driving it over the limit of tire adhesion (or if you are Turbocharged or something). if you pop the clutch when you let off it will kill your traction, if your tires are bald it will kill your traction, if your alignment is off it will kill your traction.

TTD:
1 - check your alignment
2 - check your tire tread for improper wear or extreme wear
3 - learn how to launch your car and shift properly

correct me if I am wrong, but I thought powershifting is 'not lifting' when you are shifting... so not letting off the gas while actuating the clutch is powershifting?

I haven't recorded a time since I was stock of 13.7-something more than a year ago. I am hoping to run my car next weekend and we will see but I need tires first.

also, I don't need to prove my abilities to give rudimentary knowledge on how to drive a car. nothing I said is disputable. these cars should NOT lose traction badly like that with stock power levels unless something is wrong. I think the OP is talking about driving aggressively on the street, not necissarily launching at the drag strip. a simple check over of his setup is nothing to debate.

i am stock and I am not trying to hit 11sec. I am trying to get a high 13 and hit it all the time. No point on adding power if you cant make a stock car run what its supposed to

I like that attitude

but yeah, my suggestion (not an expert) is to just check over the car as I listed to at least rule out mechanical issues first.

40 degree temps mean bad traction and lots of spining,spinging,spitting,spooking etc etc

Just keep practicing and you'll eventually get the feel for your car...

I have my time slips for November 24 in front of me. The high was 50 degrees. 60 foot times are:

1.982
2.003
2.005
2.025
2.043
2.084

245 mm all-season tires.

To reduce your, uh, spining, I'd suggest a set of drag radials given THE WAY you are driving. At your power, even a set of BFG DRs would do the trick. Lower the tire pressure, and off you go. If you really want a tire that works, go for the Mickey Thompson ET Street RADIAL. These are a streetable tire, and I've seen guys with 600rwhp make 1.5x 60's with them. Drive to the track on them, lower the tire pressure, run all day, raise the tire pressure, drive home.

Modulate throttle upon hitting next gear, apply gas as fast as possible but with no spin-def dont powershift. In other words you havwe to peddle it til you can put it to the floor. Its very easy in an NA Z, try it at 600whp in the cold lol...

You need to lift when it starts to spin. Sometimes the track can be slick sometimes its just that you break the traction because you let the clutch out so fast. Regardless you need to lift until the tires catch THEN get back into the throttle more slowly.

Don't drop the pressure on a street tire, only a drag tire does this technique work effectively.....thats the part of his post that might be unclear, so I figured I'd try to keep you from making that mistake (which I made a lot in the past).

I drop to 27psi on street tires felt better traction and no loss in trap. Any lower is no good unless you run a DR...my opinion.
