89 TTA - 698rwhp We've been tuning the TTA a bit more today. Still having wastegate spring issues until the new one arrives.. Running max boost of 28psi, we will be running 32-35 with the new spring.

Odd looking graph. How is max HP (698) greater than max TQ (608) when the HP peak occurs at the beginning of the pull and is presumably below 5250 rpm?
Is this the same turbo that had no torque last time you posted a graph? If so, it looks like you cured the low end tq issue.

Ragtop: It had no low end torque because the turbo wasnt spooling.. this time we built boost before the actual run.. These figures and the before dyno graph are just shakedown dynos until we get the spring issue cured.. Then you'll see the real numbers. Another 10lbs of boost at least. I'm just keeping everyone updated with the progress so far.

That is awesome!! I still think they're one of the best looking cars ever. I still remember seeing the article on that car in 1988, I was a senior in high school and my mouth dropped. That thing must have a nasty bottom end. What kind of trans does he have?
