But in the mean while, can you explain where's the cost coming from? Is it just transitional cost when a different size plate is introduced? Or is there some reason why restrictor plate engine development is more expensive even in the long run with a constant plate diameter?CamKing wrote: ↑Wed Jan 10, 2018 1:38 pmYou may want to talk to some of the NASCAR guys.ptuomov wrote: ↑Wed Jan 10, 2018 12:47 pm- Restrictor plate engine may require more development initially, as there is more extant knowledge about open engines. In the long run, though, the additional hp benefit from additional dollar invested will decline relatively quickly with a restrictor plate engine. The mass flow starts choking and stuffing more $100 bills into the engine will only do so much when the air flow is choking.
It is a lot of Engineering and testing on a daily to makea restrictor plate engine work. Just because you make the same power as the guy next to you doesn't mean it's not a turd at the track because you can't spin it rpm.. Back when I was involved, it was constant testing, track rental, engine dyno, chassis dyno. A lot wasn't even engine. It made the vehicle cost much more, I remember we tried Krytox for wheel bearings, Stuff was like $2000 for a 1lb.
Bottom line is the restrictor plate stuff made transmissions more expensive, rear end parts.. etc
Slowing people down just makes them try harder to go fast again.
Give them a specific valve spring to run, and valve weight.
