Like the others have said, a ton of R&D would be needed. And the teams inventories of rods, pistons, heads, blocks, blowers, ect would be obsolete.
There is no need for a new nitro motor. 1,000ft has done their goal already. Lowered the speeds and made the racing safer. And all with NO new cost to the teams, no R&D, no new parts. Also it saved tracks from being obsolete.
What more R&D would be necessary than what is already being done, Zappy?
In case some of you forget, this whole sport is based around a bunch of engineers that like to try and make things go faster- the actual 4 seconds of run is the end result of hours/days/months of R&D that a good part of the annual budget is already dedicated to.
Do you honestly think that those teams that already do research and development on their gear would just stop if told that their current combination would be the industry standard for the next 10 years? Please...
The teams don't encounter NEW costs- they just encounter COSTS... The dollar doesn't know if it is being spent on a 500ci piston or a 417ci one... The dollar is just spent. And to think that there is anyone out there running a Nitro combination today that DOESN'T take the time to sit down and try to figure out how to make something better/stronger/faster is naive at best. NONE of that is done for free, so R&D costs only go up exponentially based on the amount of exisiting available funding and the capabilities and imagination of the engineer.
To assume there is NO R&D cost in running a fuel team is just foolish- to steal a line from somewhere, it IS rocket science. Someone is always spending a dollar somewhere to make these things better- always have, always will. Even NASA has an R&D budget on a device that, to the untrained eye, looks pretty much the same as it did 25 years ago. Research and development costs are always included into any successful teams annual budget- hell, even I have a grand designated to trying new sh!te on the kid's Jr every year (tires, fuel systems, plumbing, etc)... can't get better unless you try things. Can't try things unless you spend money.
rods- expendables
pistons- expendables
heads- machining
blocks- sleeves
blowers- only 2, MAYBE 3 teams will be affected by going to a smaller huffer- and there is no guarentee that blower size will be changed... probably just the speed they spin
And don't even go with that belief that "slower is safer"... Safety is a combination of planning, engineering and fate, with a bit of luck sprinkled in as good measure. If all of those things aren't in alignment, safety due to speed, or the lack of it, becomes a moot point. Would there be less highway deaths at 55 than 75? Possibly. Would there be less highway deaths at 75 if all street cars were built like Pro Stockers? Probably. Would there be NO deaths? Not likely. Let's not fool ourselves into thinking that we are going to prevent ALL deaths and injuries in this VERY DANGEROUS SPORT by making the cars go slower.
