Kevin from CSU is usually pretty close, Did you give him your combo and have him build it? If you did give him a call he will help too.
He built it based on my specs. He asked me to call him once the car is street legal and can test better.

No one single thing. i regapped the plugs from .32 to .26, cleaned up plug wire mess, changed jetting in the carb. I never found a single issue. Looks like sloppy install and several little things being wrong added up to my issue.

Very cool. That is so much fun. A turbo car sounds so cool. You never get tired of it!

No extra boost yet. I was not happy with how the car handled. I had 298 lb. springs in the front. With the stock block N/A motor they worked well. With the IAII and turbo it is just too much weight. Every bump tried to bottom out the front of the car. Swapped to 355 lb. springs this past weekend. Hope to add about an inch of ride height and keep the car off the bottom out pads so much. Switched from 625 ml/min nozzles to 375 ml/min to try and reduce the water meth consumption. Switched from a .96 AR exhaust housing to 1.39 AR on the turbo. The .96 was just a bad choice and was giving the motor a bad case of constipation.

Lots of little things to work on. My oil temp is sitting at 210. I want to get it lower.

Brakes were not as good as they should be. Did some testing and I have a bad brake booster. I run a modified 9" booster from a 3rd gen firebird. It's over 30 years old so Iím not surprised it failed. I plan to install the new one this weekend. With luck the car will be track ready by Sunday.

The second time you get on it, and you lift, the car side loads and waddled. You can se it at the top of the screen mostly, that's what my car was doing when I ift at 146 mph and broke the diagonal link mount. My springs are also weak/bottomed out. Im wondering if that's the correlation.

I was actually thinking about that when I watched the video. While the car is up on stands I will make sure the rear is square in the car. my rear springs are 150 lb but I might need to get a stronger set soon. This car is such a pig.

Took the car for a short spin to let the tires know they're short timers. Wish I had someone to take video of the smoke show. I went back later to take this pic and two sheriffs deputies were there looking at the marks. I let them leave then took a pic as I drove down the road in my truck.
