Seems like the horsepower estimates climb every few years. Oh well, I found this interesting.

At about 2:10 in the video he has the rod in a test device, anybody familiar with that?

Makes my heart pound, can't wait till the weekend!!!

So I can go no where near that fast......lol.

Wish I could live long enough to make enough money, or gain the influence needed to wind up behind the wheel of a fuel car for a living/life.

Still after all these years, it's not one single bit, any less impressive than the first one I saw.

Thanks for posting that!

I put 10% nitro in my little alky dragster and WOW! 15% was like changing engines and was worth almost 3 tenths in the 1/8th!
I love me some nitro!!

I ran a 572 BBC injected on methanol with 10-15% nitro. Gained 3th in the 1/4 mile and made the motor sound like it was a 672"

I also ran a 632" big chief motor injected on methanol with 10% nitro. The smell is amazing and fun as hell to run.

Then I raced top alcohol dragster for 9 years and rebuilt brad anderson billet hemis almost every week, at least every month we changed a motor. I had 3 of them. Still have 2 of them.

I can rebuild those motors in my sleep.

632" big chief that I have run with nitro.

Yep, just a few strokes. Prob more to just clean the surface than remove any material.

Hey they build them in windy sand filled parking lots yanking on the TQ wrench to the point where it is useless as a precision tool and yet they are the baddest on the planet---so it is not the CI, not any precision, it is well controlled chaos and it could not be done no way no how without Nitro
That is why nobody says hey did you see the alky cars??

Cool thing is air fuel ratio is lbs air to lbs of fuel so with the weight of nitro a ton heavier than other fuels it works out so around 10-20 % you may actually need leaner set up soooooo....that means most of us with a well tuned alky car ( how could you tell alky just don't care) can ADD 10-20% Nitro and Not even change the tune up at all!!! I have run up to 16% on my fat alky tune with ease--pour in in and then Pour it On baby! You can too!
It is stunning at the TQ increase---car ran down track like it was tossed out of an airplane at 20k ft Just keeps on pulling---if you try it add 10-15% then Short shift and LUG it--Guess what it will NOT lug it will FLY!!
Get back and plugs will look like they have seen hell for a second but really they will be fine--run some more! A 5 gal pail is approx $150 depending on where you shop but it is the best $$$ I have ever spent on a race car Period!

Above around 30% the game changes big time and then it becomes a game of not breaking block caps and cranks etc--We use Tolulene in our mix to fight detonation--you should too Available at hardware store or paint store like Sherwin Williams we use a qt in a 5 gal finished mix It is essential to keep it all in one piece

A friend of mine has a rod/piston from Jeff Diehl's funny car, hard to believe the rod is aluminum....it's HEAVY.
