Great showing, saw you on the live feed.

Just saw a teaser video from Joe Simpson regarding tuning the TA. Looking forward to the full video. I bought Joe Simpson’s “how to tune the trilogy” program in anticipation of tuning my Terminator X set-up. I’m about 1/4 way through the course.

Unfortunately the car acted up on him and we were running out of time. So we had to pick up the car and repair the street injector harness and hit the road. We will get it back over to him probably later this month. I took it to him to sort out some driveability issues on the street tune most of which we're solved by replacing the street injector harness.

Totally my fault for poor crimps on the street injectors. I overnighted a pre-made harness from Holley and that solved 90% of our street driveability issues. This proves a point that a lot of wiring gurus will tell you. The proper crimp tools, though initially expensive, are worth the investment.

So on day one we were chasing a boost issue. Found a crack in a weld on the intake. Nick had to do a field repair with a borrowed welder and the wrong shielding gas in a very windy environment. Wasn't pretty but it sealed up. Then we cracked the other side on day 3. Luckily one of the checkpoints was KSR fabrication, so Kevin let us use his equipment to repair it again. Saw Tony Angelo's TA on the Dyno. Cool checkpoint!

As it turned out after studying data logs the culprit was a bad dome pressure sensor. We discovered it on day 5 when on the first pass we hit a dome pressure safety which made the computer dump all CO2 and revert to wastegate.
Looking at dome pressure in the data logs, it was very unstable. Boost curve was all over the place causing spikes. In the picture the bad sensor is on the right and new sensor is on the left. Big difference. Another lesson learned. Don't use cheap sensors in critical components.

Love your car. Tony Angelo's Firebird is my brother's old car he did all the work on it back in the 80's. Thats a back yard paint job we did in my parents' garage. Oh, and we're from Maryland too!

Does the tubing under the floor contribute to an SFI spec?

Yes it does

Very cool video! This really is one of my favorite builds. I hope to join everyone for sick week with my TA in the next couple years. It will have to wait until it’s converted to turbos, doing it with the current NA set-up would be hard on parts.

Here are the front traction bar mounts I mentioned before that tuck up inside the front assembly. These are steel instead of billet. Your TA seems to 60’ pretty well but it would give you more adjustability.

Btw the coil brackets worked out great! Thanks again
