For a 3000 lb car with 300 hp, 10 hp would be about right. Removing 10 lb of wheel weight would be like removing 15 to 20 lb of static weight, probably closer to 15 lb if it comes off the wheels, and closer to 20 lb if it comes off the tires.
So, it's about like removing 30 lb from the vehicle in terms of acceleration. The removal of unsprung weight might be the biggest benefit. Either way, I think that gives the aftermarket wheels the advantage!
