how to downshift correctly when wanting  full acceleration?
369219
I have raced cars legally and illegally in the past and the best way to downshift and get full acceleration is as follows:for example if you are changing from 4th to 3rd(or any other gears) to accelerate or overtake a slower vehicle you should press the clutch,change to neutral,blip the throttle(jab the throttle peddle momentarily just to raise your revs to match your engine speed to the wheels or you will lock up your wheels or get a jolt),then put it into the desired gear you want and release the clutch.You have to do it lightning quick for it to work properly.\nAnother useful tip to be an even faster driver is learning to use the brakes and change gear at exactly the same time when on a twisty winding country road (when going into corners which you have to change down for)this is called heal and toe.First you have to learn left foot braking and get used to the force you apply to the brake peddle with your left foot.At first you might press to much(everyone does this at first because you don't realise how sensitive it is)oh yeh make there are no cars behind you.once you have got used to that start doing it all the time when racing on a road anywhere (as long as it's safe).The trick is when coming to a bend that you have to brake and change down gear for is to use your left foot to do the braking and change gears normally with your right foot so you can leave your braking till later and closer to the bend,because your right foot is already changing down the gears and your braking whilst you are changing gear instead of having to do the same things with your right foot wich takes longer and more distance.\nWhen you come to a fast bend that you don't need to change down for but need to lift off the accerator don't do it.Just gently dab the brakes instead of lifting therefore your car is still accelerating and keeps it momentum through the bend which is alot faster(thats what micheal schumacher does in his f1 car) but your brakes will take a battering if you keep doing it.\nThey are the basics of how to drive a car very fast I have beat faster cars than mine using these things as well as others.If you want any more info on how to drive a car really fast e-mail me igenockey@yahoo.com.Hope I helped and just be bloody careful because it is easy to mess up.

Pass backwards, kick ahead, hit low and ruck over!!!

More specifically, RPM is a measure of the speed of the crankshaft of your engine, not the wheels.  Thus it is possible to blow your redline (the max RPM your engine is rated so sustain) and destroy your engine without leaving neutral.  Most engines are built to be able to exceed redline for short periods of time.\n\nMost cars nowadays have rev limiters that prevent exceeding the redline.  However, a driver can bypass this by going fast in a high gear and then downshifting.  Then change in gear ratio will cause the wheels to overrev the engine, which is why you cannot downshift to 1st gear unless you are basically not moving.  So don't do this.

use extra speed and use more energy at the start

Car vary on this but must require you to come to a complete stop, put the car in "N" or neutral and then engage 4LO. You will also need to come to a complete stop to get back out of 4LO. You might also have to go in reverse a few feet to unlock the wheel hubs, depending on your car or truck.

You can't just ask for an acceleration.  You need more factors.  All you know is that it went East 3000m and North 6000m.

Best way? Obey the speed limits. Hello?

well, i know every time i try to shimmy, i only end up shaking my butt\nso maybe if you can shimmy - just shoot ... lower?

In the direction of the velocity vector. That's the best that can be done, given the limited information you have provided.

Wind resistance increases exponentially.  Stay within the speed limit or even lower if trying to stretch the gas to get to a gas station.  It takes energy to accelerate a car and it is lost when the car brakes.  Anticipate changes in traffic lights and let the engine help slow the car.  Drive with all windows shut and nothing on the roof rack if possible to reduce wind resistance.  Keep tires properly inflated (to maximum pressure allowed) to reduce rolling friction.  Avoid carrying unnecessary weight in trunk, etc.  Accelerate slowly rather than jack rabbit starts.

Place it under your back tires and then shift to reverse.

none they work eccentrically in the down phase

jack rear of vehicle up. put a small mark on the driveshaft one you can see and spin wheel real slow and count how many times ur wheel turns b4 driveshaft makes a full revolution.

When I did this, I used CD's. One problem you may have, depending on how quickly your car puts the power down, is the lack of friction.  Overall, it seemed to work well, just make sure you have the wheels properly aligned.

You should shift based on your cadence- your pedalling rpm.\n\nKeep your pedals moving at the same speed, and shift to maintain the pedal speed.\n\nThe larger chainrings (on the crank) give you giant leaps in torque while the cassette (in the rear) fine tunes your efforts.\n\nIt really doesn't matter how you shift the bike, as long as you avoid using the two largest sprockets and two smallest sprockets whenever possible. In fact, I would recommend that you NEVER use the large/large combination, and use the small/small only as a starting point if necessary. \n\nMake sure you are pedalling when you shift, and that you only shift the front or the rear at a time...don't shift front AND rear derailleur at the same time.
