I can name several Pontiac engines that were increased by NHRA, then later reduced by NHRA.

So, are you trying to say that once NHRA has increased the hp, they can't later come back & reduce it ?

If a racer causes the hp increase then no it can't be reduced. If Nhra increases hp before it is introduced into their classification guide then yes it can get a reduction. Hope this is correct from what I was told by Nhra.
