its going the same with 410 sprinters only its not as obvious yet.

The problem is the engine limit and sticking as much money and research into only one or two designs to get as much out it as possible. There are options, The Aussie engine 12,000 bucks, 1000 and 1200cc motorcycle engines, Wouldn't be surprised if some of the outboard boat motors of today wouldn't put a whoopin on em in some instances. Big difference between 12,000 or less for a motor and 42,000, Like the ability for have a one or three car team?
