4 second quarter mile times @ 1000 frames per second..

WAY COOL !

The rush of drag racing can only be felt on the track. The starting line is so sticky that it can pull your shoes off. On the street you just spin, but as you can see, the track "Hooks up" I will drive my Pantera 130 mph without fear, But I have a drag car that goes o to 100 in 6.75 seconds and it scares the crap out of me. Last time I drove it I threw up before I made my first pass from being nervous. But I overcame my fears and had a couple of decent reaction times.

What's a 6.75/100mph car? about a 11.80 1/4 mile car?

That same slow mo is how I feel in my office right now.

This is really cool. It's going to take me awhile before I can figure some new "exciting" way to use it.
Maybe a perverted use will have to suffice?

I would be freakin at the 1/4 I bet it would run 10.70 index Add 3?

Huh? Sorry don't understand. "Add 3"?????

A car with decent traction running 100mph in 6.75 seconds would normally be a high 11 second car. A 10.7 car would probably do a 0-100 in very low 6s.

John, I have never run the 1/4 mile. They tell me the rule is you can add 3 seconds to your 1/8 mile time. 6.75 my best et plus 3 sec. Is less than 10. Maybe I'm not adding enough? It really dosent matter 'cause if I'm scared of the eighth, I damn sure ain't holding down through no 1/4 mile!

A typical car that runs a 6.75 @ 100 mph in the 1/8 mile will do a bout an 11.80 @ around 120ish in the quarter. About the same territory as a stockish 2003 Mustang Cobra with pullies, injectors, gears, and a good tune on street radials..

Good luck..

Now this is where we differ in opinion. My car got to 100 mph from a dead start in the first 1/8 and you say it will only pick up 20 mph in the second 1/8?

I suppose the only way to find out is to run it at the 1/4. Sounds like the start of a grudge matchrace to me?

Yes.

Not really a difference of opinion. Given that nothing is out of the ordinary, a car that turns ~6.75 @ 100mph in the 1/8 mile is about an ~11:80 @ 120 mph car in the quarter, give or take a tenth or 2 and a mph or 2. I'll see if I can find a few representive time slips and post them..

The numbers are amazing.

Assuming 7000 hp, each cylinder generates 750 hp.

Assuming 4.5 sec quarter and 8000 rpm, each cylinder fires only 300 times.

Each cylinder is 62.5 cubic inches. Each time a cylinder fires, it consumes a little over .5 ounces of fuel. .5 ounce volumetrically is about .9 cubic inches.

I'm going to ask Dan Jones to check all of this out for me. He knows how to calculate the value of pi and delta.
