I don't mean to sound curt about this, but in this case for the journal bearing of the PT70, spool times aren't going to matter at that hp level. This is not one of those applications that you can "occasionally go out on the town with". You're either going to have the engine build and design needed to utilize this setup for racing only, or you don't. Normally it would be prudent ask for your engine build specifications for this app, but in reality it wouldn't make much of a difference. Expect to spool higher in the upper band because of the honda's lower exhaust volume characteristics, and have a small powerband up top because of Honda's high velocity and exhaust energy. Anywhere from 670000-9000 rpms at the most for any usable band. And this is NOT the same as the Master Power SS Autochrome "T70".
