I'd propose that in addition to an increase in minimum weight and some tire rule (spec tire or limit on amount utilized per event) I'd think it would be prudent for those in the class to look at freezing the eligible engines to model year 2019 or older until 2024 season. In 2024 freeze the eligible engines to 2024 until the 2029 season, etc. It's possibly another opportunity to get it right without disenfranchising any current owners and forego all the BS politicking and bickering that comes with restrictors and other forms of competition adjustments. The shifting aids should likely go back in the proverbial bottle as well.
The engine freeze does not stop engine development or HP creep. What it does do is prevent the engine of the week/month/year. It also allows all the competitors to know that they can race with their current package for several years and concentrate their efforts/funds elsewhere.
Don't let the fear of the "no more engines left" argument carry much weight. There were at least 200 BMW S1000RR sold for every F1000 out there. Imagine how many ZX10, R1's and GSXR1000's are likely.
daryl, very good comments, the main issue with engines is that since scca or stewards don’t have a way of verifying if engines are stock or built then people tended to “experiment” with little chance of getting caught, a very well known engine builder i know well mentioned that he decided to stop building engines for a certain team because he was being asked to perform modifications that were illegal, when i asked him what would help level the field he said rev limiters as these are cheap and most engines develop very similar hp numbers at equal rpm’s.
That said, I have zero horses in this race. However, I do tend to learn from previous mistakes and experiences so thought I would pipe up with my $.02.---again
