How many rpm does a top fuel dragster turn at 9500 rpm and 4.5 second quarter mile?
As stated, it turns at 9500 RPM. Over the whole course, it will turn 712.5 revolutions.Fuel engines are, in a way, rpm limited. The slow combustion of nitro (the reason you see the wing-high flames) is to blame. RPMs very seldom go over 8000 in a race. They begin (called the "hit") at the starting line at about 7200, then the clutch 'catches up' to the engine rpm, and you will hear another slight drop in rpm at mid-track when the clutch discs 'lockup'. Then the engine will again accelerate to the finish line; about 8000rpm. At the current performance levels, the actual total times the engine turns over during a run (1000ft. track and @8000 max rpm) would be closer to 500. Therefore each cylinder fires 250 times per run. Sure seems like a $75,000 engine could do that. But a lot of times, they CAN'T!Your question itself is erroneous. You obviously were trying to ask how many revolutions the engine's crankshaft would turn during the 4.5 seconds it takes to run the quarter mile. Yes it, would turn 712.5 revolutions.But you didn't ask how many revolutions it would turn; you asked how many revolutions per minute(i.e., RPM) it would turn. Not the information you were seeking. Just as the distance from my home to Miami (1426 miles) says nothing about speed (1426 miles per hour).
Can you have a tach install in an 67 olds 442?
An electronic tach (one that measures RPMs through the ignition system, as opposed to a mechanical tach, which measures actual engine revolutions) can be installed on any car, mounted either on the steering wheel or under the center of the dash.

How do you measure distance based off of RPM?
RPM is revolutions per minute. You can not measure distance without knowing the radius or diameter of what that revolves. With diameter or radius you can calculate the circles outer length. Formulas for this is: With Radius: 2*pi*r, With Diameter: pi*d, where pi is approx 3,14 (accurate enough for most calculations but pi is in fact an endless series of numbers, 3,14159265 and billions more decimals) This length can be multiplied directly with RPM and you get total distance per minute. An engine running but standing still will however not move and the calculated answer does not have to indicate actual distance travelled.
How does an hour meter on a mechanical tach work?
A mechanical tach will register 1 engine hour for every 100,000 revolutions. At 1666.6 rpm it will register 1 hour for every hour run. At 800 rpm it will take two hours of run time to register an hour.In my opinion this was a more accurate method of measuring engine wear but is rarely used any more.10 hours on the tach means your piston went up and down 1 million times.
What were the main inventions during the idustreal revolutions?
The steam engine was invented during the Industrial Revolutions of the 19th century. Other main inventions include the sewing machine, telephone, and the phonograph.
How much fuel does a Top Fuel Dragster burn in one .250 mile run?
The engine will consume 22.75 gallons of fuel during warmup, burnout, staging, and the quarter-mile run., actual fuel economy is around 16gals per mile
What determines rpm of a car engine?
Revolutions per minute of the crankshaft in the engine.
What is a 2 liter engine?
A 2 liter engine is normally a 4 cylinder engine who's pistons displace 2 liters of volume during 2 complete revolutions. Normally used in economy compact cars.
What is engine RPM?
Revolutions Per Minute ( RPM )
How many cc is 2200rpms?
rpm is revolutions per minute ( revolutions of engine in neutral state ) pick up or torque is dependent on rpm .. 2200 is very revolutions .......... a simple 100 cc engine can create up to 8500 rpm depending upon the load on the engine ( weight of the vehicle)
What is the measure of speed in an engine?
It's usually measured in RPM - Revolutions-Per-Minute, counted at the crankshaft.
Does a tachometer in an internal combustion engine measure crankshaft revolutions per minute?
RPMs (Revolutions Per Minute) at the crankshaft.
What is the speed of engine?
crankshaft rpm (revolutions per minute)
What instrument measures engine revolutions per minute?
The tachometer.
What is RPM of an engine meaning?
Revolutions Per Minute ( RPM )
How fast does a engine belt spin?
6000 revolutions is concidered the beguining of hi stress of a 4 cycle combustion engine. you can see how fast your belt is spining looking at the tachometer wich most cars have. It tells you how many revolutions that engine is per minute. Anything from 500 - 800 revolutions is concidered the slowest speed wich an engine needs to stay on.
