Pro Stock gonna change soon

They can still use carb / throttle body scoops as long as it is not completely covered by the hood; (sticking up through).

I really wish they would have gone back to REAL TYPE bodies, less RPM and less forward speeds. Doing THAT would be more fan appeal.
(MINI wheel stands ... really ???)

Randy, do you think the 10,500 rpm limit will help with valve spring costs, or will they change to more radical cam profiles and it will remain the same?

I want stock bodies and engines back.

Personally, I think they need a 9,000 RPM limit and 4 maximum forward gear ratios in the trans... NHRA seems to have a worry about slowing them down to much.

They didn't even have enough competitors to fill an entire field at a few races last year and NHRA says they are concerned about fan appeal...?
FIRST ... change things to make a "PRO ELIMINATOR" category capture the interest of enough entrants to compete nationally.  The fans will follow but, they won't follow when there is just 14 or 15 national teams.

That means doing things with the rules so it is not completely unthinkable to start a team.  NHRA is dropping the ball ... AGAIN.

Thanks for the reply Randy. I really thought the letter was an internet hoax the way it was written when I first saw it on a forum. When I found it at the NHRA website I thought they may have been hacked too, and it was a giant hoax,LoL. I guess the new president wanted to look like he was doing something and Pro Stock was an easy target maybe. If drivers/teams remember Pro Stock Truck, they might be gun shy of jumping in right away, thinking the rules are going to change a lot again, or the class getting killed all together.

Another thing to think about with the switch back to OEM bodies in P/S is it could also create some big slick/big wheel tub packaging problems on some bodies out there. A number of the slicked-up P/S legal aftermarket composit bodies do fudge the rear roof line angle & placement, rear fender to roof line transition, and rear fender wheel opening C/L placement around a bunch to make room for the slick/wheel tub package.

Going back to OEM bodies might result in some of them having to have a lot more rear to front rake angle (sitting ass-up like a lot of P/S did back in the 70's - 80's) to make room to get the slicks up under there. Cars like the Ford ZX2 Pro Stocks from a few years ago are a perfect example of them having to fudge the back of the aftermarket bodies around a bunch from OEM to make room for the slicks/wheel tubs.

Excellent observation..... But IMO that just something they will have to work out.... Maybe a tire rule.... 31x14 max?

Good, let them have a rake.

Heck no put them on a 28x10.5 slick................ Mini tub and letum go.

Look more like a street car then.

Changing P/S to a small tired class would probably mean having to let them start using some kind of traction control devices/boxes. I would hate to see that happen in P/S.

They didn't have traction control in the 60's on those recapped 6.50 16 tires back then.

Just make do as good as they can.............. lol deal with it.

They didn't make 1300 hp either..... LOL

No but I would say the percentage difference in traction was worse lol

Hmm. Can't handle 1,300HP, get smacked around by a 900HP ride that cost less to build, and more people racing. Works for me.

I hate to see that happen anywhere.

NHRA will likely not get it right, most of the drag racers my age are living their childhood dreams with either streetable P/S type cars of their day or as fast a the P/S cars of their day, NHRA is trying to find the sweet spot again but there is no way the will appease everyone, the days of the win on Sunday and sell on Monday may be over, or maybe not. If NHRA/IHRA want to go grass roots racing they need to get over the OMotors buy to succeed programs, and recreate the class for the future generations of racers in an UNBIASED FASHION, the resurgence of the muscle car is more intense now than ever. I think the rulebook is going to look like the NASCAR rulebook, with weight breaks, inch limits, supercharger/turbo limits, tire sizes etc...Just for fun they should require a stock axle without electronic power controls

In the early 2000's the drivers (some) wanted EFI, BUT NHRA said no,why? because they couldn't police it. same thing they said before. Same reason the fuel cell is now in the front,easy to police.

switching to efi DILLGASDAVE will give them traction control , or at least some of them.

switching nascar to efi made the teams spend 3x the $$$$ ,its not going to same a dime
