If you're going to be experimenting with twinscroll of the same compressor turbine combination please plumb in a backpressure sensor or if you feel rich a shaft speed sensor. I know you're going to argue that it's not necessary for the average consumer, but your customers are not average anyway. The best test I've seen to date was done on the supra forums, but there were too many variables to draw strong conclusions. It's always good to have other data sets other than outcome data.
I don't have any comments on your designs and always enjoy your posts. I'm curious about your solutions to single wastegate twinscroll.
