Thanks for the heads up.

 

i was just gimpsing through the class regulations section just to check some stuff out and it says at the beginning of the heads up classes where it gives a little brief overview of the heads up classes that PRO FWD is either a 4 or 6 cylinder production motor. I was always under the impression that PRO FWD was only 4 cylinder motors. but when you browse down to the more describtive rules for pro fwd it doesn't say anything about 6 cylinder motors?

 

In the Hot Rod section, there is a mention that the NHRA is evaluating the use of diffusers, etc. It seems that a diffuser, or any stability-enhancing device would be beneficial (if not mandatory) on the heavily front-weight biased 180+ mph cars in this class. So for those in the process of building cars for the Hot Rod class, what's the final word?

 

Thanks for the notification!!
