Manifold / TB rule revisions

[dhrmx5]

What makes the rule ambigous is somehow the words "for the installed engine" got left off of the TB limitation.

Therefore, the BMW in question would not have the option (assuming 6cyl) of using the ITBs from an engine that is not allowed in STU, even though it came in his chassis at some point in time.

I will submit a letter to get this clarified

Good call, D.

The "writing a rule to prevent something specific" trap. I believe that's Ad Hoc committee standard error 37.1...?

Aye-yup.

Greg, you really flip-flopped on that one....

Actually, even if you add that it still presents a problem. What if you're starting out with a car from a smaller displacement and going larger. Then you're limiting the car to what came with it on the smaller displacement class. Just take Kirk's advice and scrap this rules abomination.

[Chip42]

isn't it supposed to be about displacement?

if you don't want a specific list of OEM intakes, list the forbidden OEM intakes.

you already forbid specific chassis and whole engines, this doesn't seem a stretch of the current rule style, and keeps wonky unusable and unintended consequence ridden rules out of the book.
