A while ago they were trying to build a fuel motor dyno. I believe Kenny Bernstein was footing the bill.
I believe they were trying to use parts or designs from giant ocean type engines.
Don't remember how far it got or who exactly was building it.
Maybe someone a lot smarter than me can figure out how to google the articles??
As for the 8000 HP, it is a estimate using all of the information available.
ET, MPH, fuel used, difference between 8 cylinders and 7 cylinders pass, data recorder ect ect.

If you really stop and think about it, who cares if the car makes 6,000 or 8,000 horsepower. The car still has to be able to manage that from point A to B. Though I do enjoy telling my non-car NASCAR following friends that one cylinder makes more horsepower than all eight combined in their favorite driver's car.

Sounded like a great idea to me at the time. No travel, no expense for tires, crew, rentals,
test any time day or night, rain or shine. All you need is fuel and mules and you can test anything you want
with a skeleton crew. Plus the knowledge of no one risking their butt if they have a boo boo.
Too many guys were lost or hurt while testing.
I assumed it was too expensive, too difficult or as you said.
Getting down the track, was more important than picking up HP for those guys. So the track testing was more critical.
Sounds like I'm not the only old geezer around here??

think on what? i dont understand why your making fun of my statement when i was asking you to explain the fuel consumption.since wht i guess your saying is that the more a car consumes the more horsepower it has. rite? so if that is true i do not understand since my trans am consumes less fuel and has more horsepower than my truck. -tony-

Imagine this video times 100. That's what you can imagine a top fuel car would be like on a chassis dyno, that is if they could make one that could measure that much power. (Which they don't.)

One of those cars would probably snap the straps and hop off the dyno as soon as they hit the throttle, if there was a chassis dyno that could measure that much hp.

2nd NA,blown, and turbo'd have a different BSFC (brake specific fuel consumption) ratio
NA=.50
blown=.55-.60
turbo=.60-.50
this is all off of memory so i may be off a little bit...
3rdly a motor doesn't make all of its torque unless its under a load, meaning a strain on the motor to try to not let it accelerate.
4thly by measuring how much fuel a motor burns under a load at a certain AFR they can usually give a good estimate of hp.
thats the best i can do... i have to lay down now... too tired from thinking.
they dyno the fuel system on a home made set-up and check blower etc. and its all off of data logging and fuel consumption.....at least in a promod screw anyway.
Never been around any fuel cars to learn anything about them

This is about estimating HP, not MPH. My car make's 1300hp, and I get 18mpg. I didn't get my HP rating from 18mpg.
ex.
if you have to move a block of metal 1320 ft, that is 900kg in mass, would it be less strain on a 300hp/tq motor, or 100 hp/tq motor if they are the same size motor?
ok so A CAR (which is WAAAY lighter than any truck) with MORE POWER and LESS WEIGHT is obviously going to get BETTER MPG because it has less weight to move and more power to use if needed than A HEAVIER TRUCK with LESS POWER that needs to use MORE of it, therefore sitting up higher in the RPM's for longer periods of time than the trans am, therefore, using MORE fuel.

Then I have a question about fuel measurement for Hp ratings. I had built a full caged VW bug years ago. The engine was a 4 cyl, 3000cc alcohol injected. It ran 10.30's @ 130mph and used around 3 gallons of fuel. So how does that work out for figuring HP numbers? I've always wondered what HP that thing had? 250-300? is what we were guessing back then.
old thread i know but I was wondering besides top fuel dragsters what cars/trucks make the most recorded horsepower. I've seen in the 2000's but nothing really above that mark. anybody know of any???? sorry to hijack thread
My guess is for street driven cars there is a limit. Anything more than 2000 becomes to much to handle. I would like to see some videos of the fastest street driven cars in the world as far as horsepower is concerned. I know youtube has tons of these videos but maybe as far as lsx based cars are concerned.
