I'm not trying to start another ''war'', but a F1 team most likley spends more engineering hours every month than Suzuki spent in the whole Savage r&d. Just a slight performence safety margin difference from a S40 to a F1 engine. Those engines run on the ''edge'' all the time, while ours are just a little bit ''laid-back''. We have more of a safe range than them.
A old John Deere tractor and Top fuel race car both have a spark plug for igniton. The tractor plug will last years, the Top fuel plug about 300 feet. Engineering stuff like that is part of the ''cubic dollars'' fun of racing.
