The funny thing about these "runtime" threads is the engine and pipe per say has the least to do with runtime. I've seen everything get runtime, the driver, track and conditions are the deciding factor, not so much the engine or pipe. Believe it or not there's no miracle engine and pipe out there. I've watched one race get 6mins from a XX engine and I've seen another get 11.....

As long as you can make a qual and running less than 60 min A mains, 10 mins runtime has absolutely no advantage

BTW one wreck nulls any runtime advantage, so how many guys can run 45 mins without a single hiccup?
