New cars, old cars and horsepower ratings.

Of course, I am still learning and have a long ways to go.

I have heard that in order to do this a very very very expensive O2 sensor is needed. Almost as much as the cost of the car. And you would need one for each cylinder.

Plus you would have to have an ECU with a much faster Baud rate and far faster processing.

OK, we got a lot of comments, suggestions and complaints, but here is MY list of what makes sense so far:

1. The new cars are not a problem for the RACER because they are new, it's because the HP factors are totally out of the ballpark.

2. The manufacturers have a vested interest in the new cars dominating class racing, so they stacked the HP deck, and NHRA allowed it.

3. AFHS is working too slowly, and the FI, Computer and carbureted cars have different tools available to tune, and different infrastructures for their building and race support.

4. The cost of entering the "new" car classes is prohibitive for most of the Sportsman racers that have been racing their favorite car for a long time, stacking the S/SS ranks with "bucks up" supported teams and individuals.... this is a disincentive for the longtime participants in S/SS, who are now at a competitive disadvantage in both performance and money.

Am I on point so far??? Suggestions for fixes follow on next post. Sorry, I accidentally duplicated this post.....

#3 covers two different subjects, but otherwise pretty close.
