RUSH Auto Works SR-1

I'm betting it is a GSX-S engine, not the R.

That seems likely. In fact, now that you mention it, I think I remember them saying on Facebook that it was a GSX-S. I didn't realize there was such a thing--I thought it was a typo.

Wikipedia describes the GSX-S1000 as "essentially 2005-2008's GSX-R1000 with some re-tunes for more torque."

It's listed as having 150 HP and 79.6 ft-lbf of torque at 9,500 rpm. Redline at 11,300 rpm.

If you crash it hard, it might matter ...

True, it might. Despite some of the compromises I would feel safer in it than some other cars allowed to race with SCCA.
