Exactly.

That’s why when you walk through the pits you see a power glide in everything. It has dumbed down racing.

Chassis tuning on bracket cars is almost non existent, unless you consider shoe polish a tune up.

And you are shitting yourself if you think bracket guys aren’t turning 8k plus today.

If it’s a Chevy in a FAST car it’s turning 8k plus. Bet on it.

It’s the backwards thinking Chrysler guys who think a 4 inch stroke turning 6500 is making power.

That’s why we don’t have the heads and intakes the GM guys have.

We are stuck in the 1980’s and I’m sure when I die it will be the same. Or worse.

So keep telling yourself that the advent of the 4 inch stroke crank made RPM obsolete. Because that’s just not true, unless you race a Chrysler.

You don’t know 1/4 of what you think you do if you think seeing 8k in bracket cars is the norm.
Everybody is looking for low rpm, low maintenance stuff, and very lightweight cars to further the lack of maintenance needed.
Look at the big money bracket races around the country, 6.20’s or so in the 1/8 is kinda the sweet spot you find if you sit and watch pair after pair of no box cars go down the track. In fact by far the greatest majority of door cars in box and no box run 5.80 to 6.60. Many are 2400-2500 pounds, not many are much over 3000 pounds. You can do the math. Lots of 500-600 horse cars.
Guys that race a lot DO pay attention to chassis setup, and offset that by running big tires on relatively modest horsepower to make it even more consistent.
Again, repeatability and reliability are the most key things. Running stuff 8000 rpm isn’t needed to do that.
