Pistons - the performance increases fairly dramatically as the expected life reduces. Rings can be made narrower, skirts reduced to negate friction and pins can be shorter, therefore lighter.
We need to tell Cosworth what mileage we want to get out of a set of pistons before rebuild, question is what is reasonable - what would you chaps buy?
Would 50,000 miles be an acceptable lifespan? Bear in mind this would be an extremely high-performance version of a sports car engine, and I've done 11 thousand miles in mine over three years.
Or would lower be ok?
