I happened on the video of my '73 trans Am turbo. I found the car in a machine shed on a farm. Actually a friend had it and offered it to me because a new highway was coming thru the farm and they had to move everything. It was a custom painted/interiored show car that he bought and used as a dailey driver. He bought it in '82ish. Parked it in '86 to do a full restortation because several judges told him not to place it in judged car shows because it had surface rust under the hood etc and paint chips. Anywho, it was all apart in the shed when he offered it to me. He knew I loved Pontiacs so he offered it a fire sale price. I got it in 1999 and rebuilt reassembled and built the 455 and got it on th eroad in 2002. Over the years it progressed from a 12 flat 110 car to a nitroused 10.2 @ 134 13 mpg fun monster. Then along came the turbo. To make it easier I just copied the post from another board explaining the dyno day and how they messed up the info on it. But I have some confusion on the final hp/torque numbers. I'll copy a post from another board to try to explain.
OK I got the video.

They have the numbers all wrong. The GN at the beginning hit 500hp before it puked the trans fluid all over. They were pulling it off the dyno when I left to get my TA. It is possible they repaired the line and ran agian before I got back. The Subie is correct. The first run on mine they say 788 at 15 psi 744 torque. That was the first run when the computer quit and it was at 10 psi. The second and third were run at 12 psi and the last run was the 15 psi. You can see the faster rise in the rpm in the last run at 15 psi. The last run was 886.8 hp and 822.3 torque (converted to 1065 hp and 987 Tq using %20 loss). Its possible that these numbers I just printed are the crank numbers. I have to got back down and confirm with the owner about what's right. The Print out says Maximum Power 835.0 @ 5563/102.3 mph--WCF 886.8----Maximum Torque 774.3@ 5434/109.4 mph with WCF 822.3 So I may be looking at it wrong. I did ask the operator if the "WCF" number was rear wheel power and that I add the loss factor to get final crank numbers and he said yes. So either I'm wrong or he's wrong. Even if It is 886.8 hp and 822.3 torque, that still ain't bad. By the way the video seemed to get the sound out of sync with the picture on the last 2 runs. ???
The right numbers did come out to 1065 and 987 Tq at the flywheel on 15 psi. All the runs were from a steady 3000 to 5800 rpm for comparisons. And the dyno sheet showed top HP at 5500 and 5600 thru the runs. The video sound and picture are off in the last runs but if you listen to the way the car RPMs you can hear the progression of the power as it gets shorter to the shut off rpm. Not sure I've ever played this here so here goes. My runs are the last four of the video.
Forgot to add. The dyno was in a Mustang tuning shop. They had several tuned Code R Mustangs there that were touted to be among the strongest Mustangs in the city. The shop ower said his dyno have never had anything stronger than his Mustangs at 700 RWHP at the wheels. When he saw my old TA, a Pontiac motor, a carburator, and pump gas, he kind of laughed but not to bad. He was an OK guy BUT!!!! When the numbers came up at 886.8 hp and 822.3 at the wheels, he about shat hmself. He shook his head and was amazed (thruthfully I was too, I was expecting 600 to 650 at the wheels). Jokingly he even offered me a job tuning old cars, heh. Mark L
