Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

After getting the transmission back together , it was finally time to hit the track up to test out the new suspension/transmission. Last year the car ran best of 11.64@122 with stock suspension and 1.90 60' foot. I went and got ZZP coil overs all around and upgraded to f-body brakes to hold boost on the line. First hit of the year the car goes 11.63@122 with 1.90 60' foot again. So next pass I left with more boost and ended up with 11.46@122. Knowing this the next pass was prob going to be it for the night I wanted to make the best out of it. The car built 5psi at the line and cut a 1.76 60' foot and ran 11.35@122. All runs were on 20-21 psi . Car is a full weight 1999 GTP. I'm still only running a 2.5" down pipe off the back of the turbo into a 2.5" slp exhaust. Car dynoed 430whp on a dyno jet. Car is tuned by snowflake. A big thanks to nick for tuning the car , always giving advice and helping me all the time , definitely appreciated. I'm over all happy how the car run and hope to hit the track up again soon

I don't think you need a cage until you get into the 10's, but could be wrong.

Great runs! Time to put it on a diet and take another run at it.
 
No nope no roll bar. Got the boot. And the tires are 26x11.5x16 Mikey Thompson et street bias plys. 11.49 u need a bar , jacket , and seat belts
 


lol wanna buy a roll cage? come with rolling shell on coilovers and grand am front brakes lol......
cheap too.

edit ohh and simpson harness nice race seat and fiberglass hood.......
 


Tbh idk why it's always 122. I know I can prob shift higher than 6k. I have 150# springs , st3 cam / heads. Wonder if shifting at 6500 would maybe make it go a bit faster / more mph ?
 
I'd set the shift points at 6500~.

I used to pick up MPH and backhalf always seemed stronger after the cam swap.

I'm sure the same would apply to you.
 


Yeah we did set them to 6500. Only saw 1mph increase , I think the 2.5" turbo downpipe has alittle to do with that aswell. Hoping to get it in the 10s this week. And thank you , I'm impressed with the car
 
Sounds like the restriction there.

I'd upgrade to a 3" downpipe/3" catback.

You're at the power level where it will actually make a difference, unlike most of the blower guys.
