Re: Older Superstock GT cars with scoops
It makes a difference in some factors, if ram air or not.
These are for the 1999 Firebird with the GM LS1 engine in GT:
Flat Hood: Ram Air:
Factory: 305hp 320hp
GT Stick: 305 320
GT/Auto 305 324
This past summer they gave the GT/Auto LS1 ram air cars 4 hp, not to the others.
The rest are the factory ratings.

Reason: I'm not smart enough to make the collumns come out right.
