Another interesting fact, they don't run a transmission. They simply slip the clutch to accelerate. If you've ever noticed the black cloud coming from behind the dragsters, that's the clutch dust coming off as the clutch consumes itself. I'm not certain, but I believe they're 8 or 12 plate clutches, and obviously need to be changed after every race.

almost EVERYTHING is either rebuilt or replaced after every race

wish I could find the video of the insane injectors with a clear cylinder and they show you how much and how fast it fills...

it's truely insane and a glorious display of FUCK YOU EPA

I love the smell of horsepower in the morning...

dont those superchargers make like 60 pounds of boost too? all that from only 500 cubic inches. Thats almost 1000hp per liter. take that honda boys! with your 100hp per liter

F1 engines were making nearly 1000hp per liter in 1986, and running over 5bar boost and they lasted more than 900 revolutions. Qualifying for Monza in 1986 the benetton B186 peaked at 5.5bar or around 1400hp not bad for a 1494cc 4 pot.

Thats still impressive, but its still trying to hold together 1400hp vs 8000hp, despite the hp/liter!! I was just making fun of the ricers haha. And that throttle body right on the turbo is indeed cool! isnt that motor like famous or something? I think i saw it on tv and my dad talked about some awesome bmw motor for a while

That was an amazing read... hearing them in real life even 15-20metres away you feel like your body is going to crumble from the sheer vibrations.

The F1 cars of the 80s are also amazing, and while we are on the topic of engines/big power... while nowhere near as big but watching some GroupB Rally vids notably "Too Fast To Race" and "Still Too Fast To Race" it'll make you appreciate the balls these people have jumping in a Drag Car or Rally racing of the 80s.

Also how did F1 cars sustain 5.5bar boost.... how could the turbo handle the heat? how could the material withstand the sheer amount of forced induction? Gaskets? Hardpipes?.... lots of questions and you still wonder how behind today's cars even are... if you look at the hey day of F1... but then again the worlds gone all pro-green...:icon_surp

Its all about material properties. Just wait until some of the materials chemical engineers are designing come out to have an easier manufacture process and become more mainstreams. Metals with properties 1000x tensile strength of steel yet 100x lighter.....imaging what they could build then. Just wait until "memory metal" comes mainstream. Its a mix of nickel and titanium. There are different variences of it but imagine a car with a body made out of it, you get into a fender bender, and all you have to do is throw hot water over it and it automatically reshapes itself to its original form within seconds.....yeah....that's cool

edit: the more i think about it, i could be wrong by a zero. could be 100x stronger and 10x lighter, not positive which, either way wouldn't surprise me though

I need some of that and a 5 gallon bucket of water for my passenger side of the supra.

what in the name of god are you talking about..
Those alloys already exist and have existed for some time. InConel is the main metal they use for the exhaust work.

As for memory metals, no where near anywhere of value today.

:nono:

obviously you can't read well:sarcasm: . i never said they didn't exist....i know they exist. They need to be created at cheaper costs, hence an "easier manufacture process" :nono:


Edit: certain memory metals ARE used already and for "value". Anybody ever wonder what those superelastic glasses frames are made of? a version of memory metal. For those who have never seen memory metal: http://wm.kusa.gannett.edgestreams.net/news/12-03-07-spangler-4p.wmv thats a half decent example of what it can do.

They used to race at a lower boost level of around 3.5bar which equates to around 1000hp, the cylinder head and liners were cast as one piece so no head gasket to worry about. The engine's were made of magnisium alloy. The block weighes about 5kg (The BMW engine was a road car block cast iron)

Hey guys

thought I would bump this thread...

We always TALK about this. But how does this look vs a NORMAL car? Well thanks ESPN2 for this little "experiment"

Top Fuel Dragster V. Pontiac G6! (You can replace ANY car instead of the Pontiac G6, results are the same!)

the in camera view is just hilarious between 2:45-2:51!

and the ET of of T/F car. 11 seconds! lmfao

That was awesome.

Also, F1 cars no longer run 1400hp because too many drivers were killed in the 80's...
