Thanks. Facepalm at myself. I googled earlier and didn't see any mention of it.. googled it now and the first link says just that.

And yeah, that's the old style buttdyno. It's off by about 5%.

Feel free to school me on a TT setup. Is it not possible to use a big and small turbo on a parallel setup, then? That was always my assumption of how TT'd cars worked

Twin-turbo - Wikipedia, the free encyclopedia

Worth reading to get a basic understanding. Most setups for the Z are going to be parallel setups. The RX7 is an example of a car with a sequential setup.

It wouldnt really work out because you would build very different exhaust pressure on each side of the engine. You would run into bizarre individual cylinder tuning issues. You would also severely choke the cylinders in the bank on the small turbo side as they would have a lot of trouble breating at higher RPM, making those 3 cylinders less useful.

You could do lots of complex plumbing to get both turbos plumbed to both banks, but its not worth the hassle, weight, heat, complexity.
