TAFC 5 81
Nitro Member
The last year I raced (TAFC 1981) there was discussion of TAD and TAFC going to 500" engines in the near future (TF & FC was already there, and PS was going to start in 1982) but it never came to pass.

Yes, but everyone on the list drove GM's first. NHRA did not factor Mopar out...they left on there own.
NHRA Technical Department Makes Parity Adjustment to NHRA J&A Service Pro Mod Drag Racing Series
Based on performance numbers from the first four races of the NHRA J&A Service Pro Mod Racing Series, the NHRA Technical Department is reducing the maximum allowable overdrive limit on Supercharged entries from 20 percent to 16.5 percent. This rule change will go into effect immediately.

Wow...3.5% off the blower...wowza.
its either 'lower the standards' for the others or the others have to spend an enormous amount of time and money to catch-up and the problem with that is, eventually pro mod will end up like pro stock with only 12 cars showing up!! because, like pro stock, there is very little return for your investment!

Pro Stock races NHRA National events only. Pro Mod races multiple sanctions. There really aren't many things that are comparable between the two other than they are all door cars.
How much of a difference is there between 1/8 mile set up and 1/4 mile? I notice that the PDRA cars run quicker in the 1/8 as compared to the same class running 1/4 mile. I look at the 1/8 mile times when a 1/4 mile car makes a run. Would that be because of gear ratios, or maybe PDRA cars weigh less?
Billy Stocklin said this over on "Yellowbullett" :
" So, nitrous cars are 2 tenths slow compared to the outlaw cars. No where do you have to be 908 other than nhra and the nitrous cars are killing engines to try and be competitive. They have 100k engines that are good for nothing but nhra.
The turbo and blower cars all run badass stuff, just w limits. Why hasn't anyone suggested allowing 960" engines? And if they are too fast, just give them some regulations. Very few nitrous cars have 908's compared to cars w 940/948/960s. They show to be substantially more powerful.
If you just limit the other combos, the nitrous cars will continue to blow stuff apart to keep up. They need help, not slow the others."

Maybe NHRA nitrous cars could run alcohol? Dunno what to think about that, cuz it's apples & oranges. Wish NHRA would do like PDRA & run separate P/M classes. I know that PDRA set a limit for nitrous cars at 960 CI, altho I wonder why they didn't just raise the limit to 1000 CI & be done with it.
That is the one tricky thing about keeping parity in a class with multiple combos; over time things gravitate to the most efficient combination. That's what killed Pro Comp, which had a wild number of different cars/combos. With modern day PM, I think the parity overall has been good, with the occasional tweaks. Splitting the cars up like a PDRA format would kill the appeal at NHRA races, IMO.

I agree with this statement. I also doubt NHRA wants to add what would basically be seen as a redundant exhibition class.

next it will be stutter boxes in the blown/turbo cars.....

I can guarantee the three nitrous teams in NHRA are working their tails off and getting everything they can from the combo. I think the nitrous cars bring a lot of excitement to the class, especially to the fans that have followed PM from the early days. I would hate to see PM loose a segment of cars, the engine combo's and body styles are a huge part of the appeal.
