great data ... 3k CFM :--) 45 amps :--)



that near solid fuel thing is amazing.







thanks

And the quote:"You know that you're in deep trouble in a dragster if you can suddenly see things clearly. That means the supercharger has been blown off the top of the engine and the raw nitromethane fuel has eaten through your visor. "

"With a redline that can be as high as 9500 rpm, Top Fuel engines turn approximately 540 revolutions from light to light. Including the burnout, the engine needs to survive only 900 revolutions under load. "



I do not fully understand how the above stated point holds?

maybe i can help

It takes the dragster roughly 4. 5 secs to make the run. The engine at it's peak speed is turning 9500 rounds per minute. So, to get a rough estimate you can take the 4. 5 sec, turn it into minutes and mulitply the 9500 by this. Now, remember this is a very rough estimate since the engine doesn't hit 9500 but for a very small anout of time. So your actual figure will be less. If you want to get complicated you could graph out the rpm's over the run and count them up, but that's way too much work in my opinion, unless of course your the engineer designing the thing.

Clear as mud?

BTW:

the above calculation will give you 712. 5 rounds for the quarter mile, so you know your actuall rounds will be less. Then you add in the rounds (I'm guessing from their figure that this is a few hundred rounds)for the burnout and it gives you the total of 900.

getting any clearer?

Either way, when you see them run in person it's nothing short of awesome. The feeling in your chest is something you can't describe.



I tried to take a picture of them as they left the line. Even with a tripod I couldn't do it due to the vibrations at launch.

I love watching the JET cars. I get to stand at the staging line and watch. The shock waves of them lighting the afterburners literally pounds your chest. I have some good pics of the launching.



I think it takes a brave man to straddle a dang jet engine and ride it down the 1/4.

Yippeee! pictures pictures pictures!!! Oo. Oo.

well, come on. lets see em.

I found this thread while searching for something else.



At the '04 Mile High Nationals, I was truely in awe. The top fuel cars are unbelievable. I felt like a pager on vibration mode sitting on a table top, buzzing, standing there watching. I knew immediately, I'd be back for the '05 Mile High Nationals! Simply AWESOME!

I will be going this year as well, as well as the Jet Car Nationals later this summer! Craig, we will have to meet up there again!

how bout a gas turbine straped to a go-kart

Looks like mine, Drew, except mine isn't on a go-kart yet, haha. Homemade turbocharger turbines are fun but not very user friendly. On mine, the turbines keep burning up.



But a true turbine engine (read a lot of $$$) would be cool for a go-kart. I even saw a jet powered stand-up scooter powered by a radio controlled scale-jet type afterburning turbine.



Sorry for not staying on topic!

Sounds good Nick.

9500 rpm is peak, not average. Since a run is about 4. 5 seconds, that means that the revs= (9500/60)*4. 5
