UIM · Forced induction
UIM answers this part for 24 of its classes. 1 of those answers are permissions, with or without limits attached, and 23 are not. 5 are inferred from how the class is written rather than quoted from a rule naming this part. 8 are inherited from a parent class the rulebook points at.
24 classes, grouped by the answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules. 8 of them publish no component rules of their own and are marked below; for those, the link to the parent class is read from the categories table rather than stated in the rulebook.
No rule, this is an open class Our reading, not a rule we can quote at you. This class carries no stock clause at all, so anything unlisted appears to be open. The rulebook does not say so in terms.
Not legal 9 classes
Explicitly prohibited by this class.
The rules do not say 1 class
NO INTERCOOLER RULE EXISTS for Runabout GP2, in a class where superchargers are legal. Do not assert either way.

Aftermarket intercooler: if the rule your class applies reads differently to you, or the rulebook has changed since this was read, ask. We answer with the section we read it from, or that we have not read it. Ask a rules question.
