We made in the stock bottom I think 707 or 717rwtq (800rwhp) through automatic and using the YSi using the restrictor plate design at 16.5psi upstairs. (However, we were spinning about 69k rpms on the YSi)

Thank you for clarifying. Ysi, your funny.

What about the torque ramp in? Would the restrictor support more torque at a lower Rpm?
