Pulsing and Gliding Easier than Ever...

Hey Guys!

I'm new to this site and wanted to share with you a few easy and fun strategies to help squeeze out an extra mile or two:

I like to call this the little "Shake-A-Roo" or "Shiz - Ake" (Shake)...

The Shake-A-Roo will increase the duration of your glide. A quick left right shake of the wheel right before your glide is what loosens those brake pads. Disc brake pads tend to hug against the rotor even after the brakes have been released from application.
When approaching your glide...Do the little "Shizzake"

This move ultimately frees the brake pads which reduces rolling resistance.

The second move that I use...the "Clutchless Neutral Shift", also referred to as CNS. This is a great way to reduce wear and tear on your clutch. When you're at your peak of the pulse, approaching your glide, ease off of the gas pedal, shift to neutral. There is no clutch needed. As you're slowly lifting the gas, the tranny slides into neutral like butter baby. The CNS move makes pulsing and gliding easier than ever for you and your friends. I hope these moves work for you, good luck.

Re: Pulsing and Gliding Easier than Ever...

The roads I drive on have enough texture to rattle teeth. Gots built in shake.

My 06 Civic does not like clutchless anything. Maybe with some shifter kits. Meaning the bushings for the tranny end of the cable. Ridged kit for the shifter base and a short shifter. Maybe it would like it. My Civic is as rubbery as a LeCar in the shifter dept.

The Ranger will go to N but its not worth the effort or time to hypermile. Its job is to haul when called into action. The rest of the time rusting is its mission.

Re: Pulsing and Gliding Easier than Ever...

Honestly, try it clutchless. You will be amazed.

Since your car is an 06, I would imagine it could only be easier than us with older models.

The CNS is a special technique. I can assume from your post that you may have tried some clutchless maneuvers in the past with much resistance from the car.

But that is the beauty of CNS. As Dave stated, it really is so easy (I can't believe it's not butter!)

The whole principle behind CNS, is that the transmission must be in a neutral state itself. That is, between "load" and "no load".

If you try to go N while accelerating (load), you will feel resistance.

If you try to go N while coasting in gear (no load, you will feel resistance.)

However, the process of slowly lifting the gas while in gear WILL allow the stick to slide right into N.

Not only does this save wear and tear on the clutch components, it makes gliding even easier. I can CNS and kill the engine in about one second after hitting the peak of my pulse.

Re: Pulsing and Gliding Easier than Ever...

Hi Charles:

___Although the clutchless approach may work for some vehicles for smoothness, nothing can touch a FAS at the same time the clutch is depressed while disengaging gears. Why not bring up your current numbers a tad and once you are approaching a peak, run with it from there?

___Good Luck

___Wayne

Re: Pulsing and Gliding Easier than Ever...

Wayne,

Are you implying to kill the engine at high RPMs?

Even in this site's glossary, it suggests letting the RPMs stabilize before shutting down for FAS.

Also I guess the whole idea here really, is not having to clutch because it is easier.

Re: Pulsing and Gliding Easier than Ever...

I sometimes do what you refer to as CNS, but never thought of it as a clutch saving technique. You're probably right, although
if you do it wrong very often you'll have excessive synchro wear. I mostly do it out of laziness! One less pedal stroke.

I'm interested in the shiz-ake too. Would definitely like to coast/glide better if possible. Anyone else tried this?

Re: Pulsing and Gliding Easier than Ever...

That sounds like some interesting ideas. I didn't know that a little shake could loosen the brake drag. Is that just as applicable for FWD as RWD? It might help my front wheels, but I think my back drums are dragging a bit as they're well worn from my previous driving habits (will be changing them asap.)

Lately, as I've been experimenting with some basic FE driving techniques, I started to coast and glide (with engine on) and realized it probably would put lots of wear on my clutch if I do it all the time. I'll give the neutral shifting w/o clutch a try for sure.

Re: Pulsing and Gliding Easier than Ever...

Hi Charles:

___You are not at high RPM's when the Clutch goes in and a FAS performed. I can only give you the experience I have in the Ranger and she has seen south of 70. Using the clutch can save a whole lot of issues vs. not so why risk it for no gain in FE?

___Good Luck

___Wayne

Re: Pulsing and Gliding Easier than Ever...

maybe i am dense today......are we talking about doing this with a 5 speed? i know that with older cars i used to be able to take it out of gear without the clutch at certain speeds. i didn't realize it would work with newer cars. my HCH is a manual......

Re: Pulsing and Gliding Easier than Ever...

Yes, with a 5-speed. It's easier to take it out of gear than get it in gear without clutching, and easier to upshift than downshift this way.

But I don't see the point. If you're easing off the gas to unload the engine as you take it out of gear, there would be little slippage of the clutch plates anyway, so there would be little wear if you just used the clutch. If you mess up and there is still a load, you're stressing the transmission in a way it's not meant to be stressed, and transmissions are expensive.

And putting it back into gear clutchlessly, you have to rev match (engine to transmission) to get it to go in, and if you're rev matched there would be little clutch slippage and clutch wear in this case as well, so again why not just use the clutch?

You want to shift as gently as possible anyway both to baby the clutch and trans and for economy reasons.

Clutchless shifting IS used in motorcycle roadracing, especially upshifting, sometimes with an ignition interruptor in the linkage to momentarily unload the engine. But this is done to save time because acceleration is everything in a race. And the transmission needs to last only until the end of the race.
