The people writing the rules have not forgotten their physics, which is why the
draft rules require stock bore, stroke, CR and ECU. The final draft may require
stock internals as well, though this is still under discussion. Will there
still be differences in engine performance? Sure, but that situation exists
today in DSR with their $12,000 engines and doesn't seem to be a show stopper.
Besides, the only way to achieve perfect engine parity is to require a
single-source sealed engine, which isn't going to happen for a variety of
reasons. In the end, perfection isn't required. This is a builders class, and
people preparing a car for it will have to make informed decisions.

necessary to get that extra 10HP out of
those highly stressed and advanced motors. Or, at the same peak HP, to get
more reliable service or broader HP and more torque out of them.
With restrictors, a built bike motor that makes more HP over a broader HP
range WILL indeed still accelerate faster even if peak HP is the same as
other motors. I see very high compession build-ups of those street engines
being the primary trick in an intake restictor class.
People who advocate restrictors generally also forget their physics and that
torque is what determines ultimate top speed, not HP.
Running at the edge with MC power, one probably just trades broken rings,
bent valves, broken rods, and broken tranny gears for the cooked rings and
piston tops in a 2-stroke. :->
To each their own!
