TT 68 Camaro update. 9.02@150mph! Finally made it to the track with the new combo in my Camaro. First pass I launched at 2psi to make sure how the car would react and short shifted at 6k. Went 6.60@111 in the 1/8th and 10.08@142.74 in the quarter with a 1.72 60ft.
Next pass I tried launching a little harder at 7psi and shifted at 7k. Car felt like it started to come up then unloaded the tires. Went a 6.29@114 in the 1/8th with a 1.57 60ft. I let off at the 1/8th so I wouldn't get kicked out and called it a day.
I was very happy for only 12 pounds of boost driving it to and from the track 45 miles each way. Going back this Sunday for my license passes and hopefully work on the launch.

Went back to the track Sunday for my license runs. Last 2 passes were 9.6@145 and 9.5@145. Looked at the log files when I got home and actually touched 13psi on the last run!
I made 7 passes total on Sunday and didn't have to lift the hood once. Man I love turbo cars!!!!

You'll be happy you do. I was all against it, but the first time I pulled it changed my mind. I no longer have to use the foot brake till about 80mph now. And actually have had to use it once when the car got out of shape about 1000 feet ou
Buy a good one. I chose a Stroud and pleased with its non violent opening

How do you have yours set up to release? Spring launcher, air launcher or some other method?

I have to remember no to show turbo threads to the wife....
She's not thrilled about the bottle (haven't used yet) and said NO! to a turbo
Congrats on the ET's and License

Yes, mine has a lead foot also...But my Camaro is too much for her with manual steering, full spool, and such. Nothing like the "ease" of a new car 
Keeps her out.

So this season has been nothing but fuel and spark issues. Finally starting to get things figured out but clogged the injectors AGAIN! Added a 10 micron filter in front. I thought a 100 micron pre and 40 micron post would be ok. WRONG!
Made (3) passes all 9.0, but car mph was slowing down every pass and breaking up going down the track so I stopped. 60's are better. All low 1.3's with the new PTC converter but still some work to do. Trying to get back next week with the new filter and clean injectors for my 8 second pass.

Well I ended the season with a best pass of 1.31 60' 9.02@150mph. Only clean passes were on wastegates only with C02 turned off. I was hoping to get a clean pass before I took it apart for upgrades but it wasn't in the cards. After I tore car down and sold parts a member here mentioned he had the same symptoms and after checking some logs noticed my PID settings were most likely the issue. Dome pressure was all over the place. I guess we will find out next year!
