The RPM's is what makes stuff work.

Given the same h.p., the engine with the most power pulses wins.

[CamKing]

why don't they just run the current production engines??

Because that would be smart, and that's not really NASCAR's thing.

They had the goose that laid golden eggs, and they made goose burgers out of it.

Pretty stupid answer really!
And I thought you knew a little about this stuff?!?

After last night's crap fest, you still want to assume NASCAR knows what they're doing?
That was an f'ing joke, not a race.
Now the NASCAR brainiacs, are going to turn all the 1.5 mile track races, into pack"racing" crash fests.
NASCAR loves to promote the sellout at Daytona, but doesn't like to talk about the removal or 60,000 seats, to make it a sellout. That's a loss of 37.5% of their fans.

As for the engines, race-trim LS7 engines would be plenty reliable. They would require more cooling, but so what? Teams/manufacturers have spent a ton of money, developing engines that require less cooling, so the cars don't need as much grill area. What has that added to the fan experience ?
If NASCAR mandated a larger grill/radiator area, and didn't allow it to be taped off, do you think the fans would notice ?

101000 in the stands at Daytona today!Tom

They had to reduce the capacity from 160K to 100K to have a sellout. That's an attendance loss of 37.5%

The high RPM at the superspeedways is mandated by a gear rule, and the rule is only a few years old. A few years ago, they were turning thousands of RPM's less.

Wow! Lol

So what your saying is as long as you keep them cool, they would be fine?!?
How many rpms in your example?
How many races before the block is thrown in the trash?
How are they going to make the 750+ mark for tracks under a mile?
Let me guess, one of your hydraulic rollers?!?
It's working out so well in the trucks! Lol

Wow, you've really lost touch. Maybe you shouldn't spout your negativity without doing some research first!
Why the sour grapes.........not relevant anymore?!?

I'm saying that there are plenty of expenses in NASCAR that can be addressed with simple rules. All 3 of the current NASCAR engines were designed around limited cooling. It cost a ton of money, and brings nothing to the sport. As for LS7's, go ask the Daytona Prototype guys how long they last. You don't need 750+ hp at the short tracks, there's other ways to bring the average speed up at those tracks. As for RPM's what RPM were you turning at Daytona, before the gear rule was added?
You need to face the fact, that the only revenue increase in NASCAR, is in the sales of used stadium seats that they've removed from all the race tracks.
Yesterday was a crap-fest, and that's what NASCAR thinks it's fans want. That's not racing.

Sometimes I get nostalgic and put on an old race just to hear Ned, Benny and Bob who let the drama unfold before them instead of manufacturing it. NASCAR has lost sight of what’s important, the racing.

I don't really follow this. But no one has run a V6 DOHC engine in the Daytona 24 hour race that would work for the 500?

OK, Mr Hendrick, how many RPM were they turning at Daytona in 2010-2013, when they were putting 167k in the stands, with 14-17 million TV viewers?
What dynamic do you use, to show today's NASCAR is better then 2010-2013 ?
Remember when NASCAR had 43 cars, starting the Daytona 500? This year, you had 35, plus 5 guys that made the ceremonial 1 lap, and then parked it.

It has nothing to do with sour grapes. I have a lot of friends that draw an income from NASCAR, and I don't want to see them out of work. Unfortunately, that's the way it's heading. Talk to anyone in the money side of NASCAR, and they all paint a grim picture.

The LS engines they ran in the Daytona Prototypes made 550hp, and were limited to .625" Valve lift.
The Porsche Cheyenne V8 that won the Daytona 24 hours, makes 570hp in turbo form from the factory with a 100k mile warranty, so at 550hp, it was almost bullet proof. It was limited to .500" valve lift, and hydraulic followers.

IMO except for the 2 super speedways racing has never been better.If you look at the "good old day" with the winner being many laps ahead and the 3rd and 4th even more back.Engines dont break anymore for the most part,cars are going stupid fast and are evel to drive.The wrecks yesterday for the most parts were caused by the veteran drivers that wont lift.The cars,thank God have become so safe they feel their superman and wont get hurt.I have no issue slowing the cars down.I have been to a lot of races and im 100% sure no one could tell the diff with 180 MPH and the "magic" 200 number.I also believe that ALL sports have taken a big hit in the stands and TV because of the net and social media.Also the younger people wont give up 4 hours to watch a race.I for one would not have a issue with them trying some timed races.3 hours and its over.FWIW,Tom

[Truckedup]

And if the engines are closer to stock and a few blow up, no big deal....The photo I posted of 1959 Daytona photo finish, how many blew up engines back then?

Problem is, NASCAR has changed their rules, to make all the 1.5 miles races, like the Super Speedways. They're dropping the HP back to 550, so they will have to run flat out in a pack. The drivers don't lift, because they feel safe, they don't lift, because they don't have any HP. You lift, you drop 20 spots. HP can get you into trouble, but it can also get you out of trouble.
