bigterp77 i've been looking into some engines and you seam to be correct.
engines under $200 provide about 2hp at 30,000rpm, where as engines over $220 have about 2.5hp at 33,000rpm.
.5hp might not sound like a lot, but on such a small scale thats 25% more power.
so i guess my next question to people out there.
How does the OS V-spec compare to the Axe Rossie sport/Speed engine.
