Well, I hope the link works.

Don't know the author but I'm thinking what he is thinking. B-O-R-I-N-G.

You would think they would be building something like the LS1 or gen 3 hemi, longer runners. I wonder if variable length runners would be allowed, although it's for low end torque so they probably don't need it.

According to a couple well known Pro-Stock engine builders I have spoken with........the first EFI testing with cobbled existing intakes and the new rpm limits, had them down 80-100HP. With more testing, new intake and cam profiles and even WITH the 10,500 limit, some teams are only down 25HP at this point from last years motors.

That's what I heard. But that isn't the issue is it? If they left it open, maybe they would make MORE HP. Now, they are struggling to get back to square one. That is the ASScar model to the "T". If NHRA was about going fast (which for decades has not been the case) they would have done it differently.

Just looks crappy that Holley and K&N are the main suppliers. The eyeball test smells bad.

That's ths issue I suppose. Being close to the 10500rpm HP is all well and good but that will be down even more from the true old power numbers. I have a buddy who works for a competitive PS team and they are struggling but getting better every day. Started with barely getting them to run to getting more and more power with each new evolution.

These guys will get it figured out and in the end make more power than they did with carburetors. It's time to move on, fuel injection is the now and future.

Geebus, some people will NEVER get it. It has nothing to do with EFI, carbs or hood scoops.

Unbelievable

I get it! The past is gone, never to be here again. We'll never see Ronnie Sox lined up against the Grump again, NEVER! Do I like bar soap cars? NO! Would I like to see them based off a FACTORY body? YES, YES! Do you think they should run current bodies with 500" carbureted engines? I DON'T! IMO run current production cars with current production (fuel injected) engines. Wait, we already have that.

You have made a point of bitching about PS at every opportunity. You don't like it, WE ALL GET IT! Stop point bitching and complaining about something you won't watch or support. I will watch and hopefully the Mopars will make a respectable showing.

He doesn't like it and never will. But regardless of what he thinks, the changes, including the rpm limit, WILL be better for the class and a serious cost saving effort. Are these MY opinions?........NO, this comes from people who actually participate in the class. Are they ALL happy about it?.....likely not, especially the unlimited budget teams, but for the most part, the changes seem to be widely accepted as a good move.

Seems some want it like the old days, where it was determined that hard work, determination, thinking outside the box and development meant winning in Pro-Stock..........that's a great thing if it's the 70s. This ain't the 70s and it doesn't work like that anymore. These days, it is he who strokes the largest check wins. So to leave a class like Pro-Stock "open", the winner will be whoever wants to win the "mine is bigger than yours" contest. Not many with that much money CARE about Pro-Stock..........so that would for SURE be the death knell of the class.

Will these changes "save" Pro-Stock?..............I have no idea and neither does mister expert, but it doesn't hurt to try.

That plenum was a loser 20 years ago.

I would have liked to see it be open as far as ECU'S and the other components. I think it would have been good for the aftermarket.

Regardless, it would be interesting to see how it pans out.

Monte bought up a very very valid point. Let's face, the last 5-10 years have been a rich guys play ground. If guys like Ken Black weren't bankrolling his son in laws racing, where would the class be now?

Great article. Thanks for posting! Latent heat of evaporation = carburetored cars big advantage! Enjoyed reading some of the answers also.

and I thought YOU were Mr expert?

Like always there is two sides of the coin ain't there? MPFI you don't got to worry about the fuel dropping out of suspension or getting the exact same amount to each cylinder, and it is easier to get the exact same air to every cylinder also. I bet if the choice was left up to the teams to keep carbs or go EFI they would all switch to EFI fairly quickly.

I thought they had to use throttle body injection
and not muti point(at the head).. if so this is
still a wet intake.. but I'm not sure what they
have to use for fact

NASCAR is TBI prostock is MPFI

Crizila, consider this: The cooling effect is offset by the fact that the evaporated gasoline takes up room in the airstream, limiting the air (oxygen) available to the engine. For years and years it has been accepted that most power is made when the fuel enters the combustion chamber as tiny droplets. Lots of surface area on which to react, much much denser than evaporated gasoline

I have not done the math to see which effect prevails in a gasoline engine.

The NASCAR FI system is TBI, so is NHRA's. So the intake is wet.

R.

Thanks for the info

NASCAR is NOT TBI...........It is port injected as well. Holley makes the throttle bodies

No you DON'T get it. Evidently you never will. Did you read the link? I don't care about carbs or EFI. Why not let the TEAMS decide? Why not open it up to manufacturers other than HOLLEY? I heard Montes complaint that NHRA can't police it. Then NHRA isn't ready to move forward. I'd love to see the TEAMS decide what is BEST for THEM. You could have carb/scoop or EFI/scoop or EFI/no scoop. Why not have the CHOICE?

Nope, you won't EVER get it. I never asked for Ronnie Sox or any of that crap you posted. But it is sickening to hear people like Monte say "we had to do something" and "this is better than nothing" and will it work...I don't know". Then WHF is the purpose of NHRA? What was the purpose of Pro Stock? It was to give the ENGINE and CHASSIS BUILDERS a place to show off their abilities to think outside the box. In 1982 (IIRC) it was 2350 pounds, 2 carbs and 4 gears. That was about it. You could weld it, move it, do what you wanted. But somewhere along the line came the WONKS. The WONKS have killed everything. The WONKS gave YOU "soap bar cars", engines that are so similar as to no longer be even "corporate" but just PS with a different name on the valve cover. How boring is that? Look in the stands.

So you will apparently NEVER get it. I'd rather kill the class than do this to it. When this 30 something generation gets itself into powerful government positions (the next 15-30 years) we will see more and more of the WONK mentality.


I'm not pining away for the old days, I'm not waxing nostalgic. I'm calling stupid stupid. You'sd have to show me the math where ANY of the changes being done by NHRA saved one thin dime. By not allowing competition, NHRA has again raised the cost of racing. As I think about all my years in the business, I can't think of a single rule, not ONE rule NHRA has made to save money has done it.

Nope, stick a fork in PS. Or better yet, just shoot it in the head and kill it humanely. That's the ONLY way to reduce costs in PS.

Nope, Justinp, you don't get it.
