In plain terms, acceleration is the rate of increase of velocity. The symbol for acceleration is a. To calculate acceleration of an object, we use the following equation:
a = Dv / Dt
a=acceleration (m/s2)
let's assume 90 Mph, 90Mph which is 40.225 metres per second (assuming this speed at the
200 foot marker)
Now acceleration = change in velocity / time
so in our case Acceleration =40.225 Metres per Second / 2.3 seconds
So in this case we are accelerating at the speed of 17.49 Metres per Second (approx 39.1mph x 2 seconds (m/s2) )
How can this be used to figure out THEORETICAL
POSSIBLE MINIMUM TIME IN 200 ?FEET - Stay Tuned more coming.
.....and the Answer is > No, Horsepower is not real, it is a simple Mathematical formula.
Revolutions per minute of a given motor times (x) the measured torque divided by (/) 5252
-5252 is the Universal accepted worldwide constant. (for measuring horsepower)
Horsepower = RPM x Torque
------------------
5252
-Ok what does this mean? We can measure Torque. Torque is the actual measurable turning force created by a motor.
-Torque is NOT exciting, but it is necessary to measure it, in order to give us a Horsepower Number Horsepower IS Exciting. People love to discuss Horsepower, and how much Horsepower their neighbours lawnmower or snowmobile or late 70's muscle car has / had.
OK so how do you find out how much Horsepower your motor has?
A) Take it to a Dyno (short for Dynomometer) -a torque measuring device.
B) Ask your neighbour (he had a smokin' fast chevelle in 1968 Yup he'd know)
C) Add up the Sum of the parts' HP Numbers that they advertise when you buy individual aftermarket pieces online + what you think your motor had originally.
D) Drive really fast and tell everyone how much HP it "feels" like you have.
You guessed it A) is the only correct answer.
Your day at the Dyno will be a LONG one. You will show up early and spend 2- 3 hours getting your motor adapted to turn the torque arm of the Dyno.(fuel system setup, cooling, oil etc...)
Then you will make a 'warm up' pass. This will serve a couple of purposes, 1- check for leaks, sparks, temp spikes and listen for any really unusual sounds (you know the ones that make you nervous). 2- Set the dyno range, basically where does your engine make power (at what RPM) and what level of resistance should it be started at.
Now comes the cool part (or not so cool, if you have unrealistic expectations) . You shut the engine off do a manual timing check, do one last valve train check, back on go the valve covers > then fire it up and and your engine is in the hands of the guy you just paid $400.00 - $1000.00 for a Dyno session. He will slowly rev the motor low then apply the load he feels your motor can take - Here is the scary part, he pushes the hand operated throttle down and you watch and wait to see what numbers begin to show up on the screen. Each pass will only take a few seconds, but even the best put together motor will groan and resist and protest before overcoming the torque arm to a certain amount, all while being measured, calculated (yes this is where that cool formula above comes in)
Some variables, you should take the time and effort to test while you are paying out the BIG dollars.
Temp> You will be amazed what temperature your engine actually makes Hp at.
Valve lash > modified motors can vary wildly on where they like the IN. and EX. valves lash set. anywhere from 18 - 300
IGN. Timing> Don't start too low here and, stay away from the high numbers all together 18 btdc is low, 40 is HIGH.
Headers> Bring a couple of different configurations with you, longer, shorter, 1 7/8 or 2 1/2 you won't know till you try.
Jetting> If your Dyno guy is set up and experienced you will find the 'right jetting' Fat is NOT safe, it is JUST wrong.
Tune to the right jetting on the back and the front barrels and learn your jetting range.
Cam Timing> You want your degree wheel and your cam card on hand, unless you know your clearances tread lightly here.
Oil> Yup Oil, if you have a good oil pump, thinner oil makes HP -SIMPLE- it moves faster, requires less friction to pull the heat away from the areas it is lubricating, and takes less power to move through the motor MORE HP, for free.
Fuel> Bingo.... be realistic about the amount of compression you have, don't bring 114 Octane if you have 88cc Heads, it is a waste of time and money. Av Fuel 100LL will make great horsepower if matched to compression. Octane is simple - the HIGHER the number the SLOWER the burn. Fuel does not explode it expands, creating a force pushing your piston down through it's stroke. (off on a tangent here sorry). If you bring too high an Octane rated fuel you will need more timing and ultimately make more heat and less HP, just to fire a fuel that your EGO not your motor needs. CC your heads and do a static compression test be informed.
Vacuum> if you are running a vacuum motor, you can play with your vaccum pump and crank it up a little. I have been at the dyno and personally seen a few extra points on the pump add; 10 -15 and 25 hp, again free hp if you can keep your valve cover gaskets and oil pan gasket from being sucked in and creating a leak.
Hope this helps clear up
some of the misnomers out in HP land, but I bet if you show this article to your neighbour Jethro, he will still tell you
his 1968 chevelle made 800Hp and could burn rubber even better than the Thundercat last fall at Wheels 'a churnin. (yah
