Sweet looking TB. I presume this is a prototype and not done yet. Are you guys planning to play around with different shapes and sizes for the TB? Sometimes if you shape the TB wrong you will slow down the air flow so much that you can lose a lot of low end torque ( and gain high end).

Also, do you plan to recess those philips head scews? Use some nice flat head S.S. screws instead to get them out of the air flow?

Keep up the good work.....
