Yes, twincharging works... I get boost in the white car as soon as the supercharger kicks on at 75% throttle, and then the turbo spools up extremely quickly when the supercharger is on. The datalogs show 19 psi at 4000 rpm
It runs mid-14 second 1/4 mile times, and is only 1/2 second slower than the 1JZ car when it had stock turbos.
The blue car runs, but has not been to a track with the big turbos yet. When the car was almost finished, both tracks by me closed. I had nowhere to run it. One has opened up again, so I'm working on it again. More electronic stuff to do, eventually it will get to a track.
I'm hoping to get boost from the small turbo at low speeds, then both at high speed.
If that doesn't work, there's a nitrous bottle in the trunk.
