I stumbled on this article about types of shifting, although I've never tried it does anyone here use speed or powershifting on their coupe once in a while? Since the coupe has a little delay when letting off the throttle for like a quick sec(rpm doesnt go down quickly) Does this affect the coupe?

Whoa,

I never powershift b/c I want my tranny to last as long as my car at least. My friend went through 2 trannies b/c of this. Same with another friend. It's not worth it, trust me on that.

 

Yeah power shifting is just not a good idea unless you are in a race with big money on the line. You can and will seriously mess up your transmission. And the gains from doing it are minimal.

 

how about speed shifting any comments? Or has anyuone tried it?

 

i know powershifting is killer, but good when you race... to me it sounds like a person who is powershifting it makes your car sad... [img]/w3timages/icons/frown.gif[/img]

You have to be veeerrrryyy fast with a power shift and cannot miss. Not recommended for the faint of heart for sure...Missing the shift while standing on the gas=jacked motor and or tranny. Get fast enough with the speed shift and you will be fine. Most people that will pull up next to you at the track will not powershift their car, you tend to have a little too much adrenaline and testosterone flowing freely through your system to be any good at it....

sup foolio, having a nice vacation? I went to your group looking for my Cd rom. they informed me I need to wait till you get back.

but ya about power shifting, the torture it does to your car doesn't make you feel very good when doing it. In a manual car it feels much like revving a automatic car to about 4k then dropping it from neutral into drive. tha thought of what it's doing to the drive tran makes your face like [img]/w3timages/icons/crazy.gif[/img]

What do you call it when you shift by lifting the throttle, moving to the next gear, and pressing the throttle again.. without ever touching the clutch? That worked in an old 86 Accord I had most of the time. Made a horrid noise when it didn't. I wouldn't recommend it. [img]/w3timages/icons/smile.gif[/img]

that's the same thing they had in some old VW bugs. I think it was called "auto stick"? [img]/w3timages/icons/smile.gif[/img] I couldn't drive worth crap in that. I had a girlfriend that let me drive her auto stick bug one time. It's just stick without a clutch, my friend had a civic that the clutch went out on, we drove it the same exact way as that bug.

Just take it out and shove it into the next gear, who cares if it grinded a little.

Terms are different from what I learned as a kid. And we had one more method of shifting a manual tranny.

"Granny" - same, same
"Speed" - same, same
"Power" - we called this "Slap"

What we called "Power" shifting was when you shifted between gears without using the clutch. I.E. You matched the RPM of the input gear to the RPM of the output gear, for the next higher (or lower) manual "gear", by adjusting the "Power" (throttle) of the engine. Lousy for racing but smoother than an old automatic or "Granny" shifting.

I've "Granny", "Speed" and "Power" shifted every "manual" tranny vehicle I've owned or operated. I only "Slap" shifted those whose shift linkage was short, tight and precise. And you don't "need" a true short shifter (short stick and short gear selector levers). You can decrease your time from one gear to the next by holding that "long" stick shifter at the base. I.E. A "shorter" lever arm needs less distance to travel through the same arc as a longer lever arm (like at the **** of the stick). It just requires more force to move that "shorter" lever that "shorter" distance.

Vehicles I've driven with a manual tranny:
0) '57 Chevy - ???cid - 3 on the column
1) '66 Bug - 1600cc - 4 on the floor (obviously)
2) '69 Fairlane - 302cid - 3 on the column
3) '67 Camaro - 327cid - 3 on the floor (Muncie)
4) '62 GMC van - ???cid - 3 on the column
5) '79 Colt - 2000cc - 4 on the floor with a 2 speed axle which couldn't be power shifted so I always had to use the clutch (Drove this one like a 5 speed with first four gear changes done in low axle gear and then shifting to the high axle gear. Also drove it like an 8 speed, by alternating tranny and axle gear shifts, but only when showing someone that it could be done.) (Yes, I owned a ricer (Nippanese 4 banger w/fwd). Got rid of it when the rubber band broke at 50K.)

Never broke a tranny. Did burn 2 clutches on the Bug (one was from a VW bus) 'cause of too much fun burning rubber in 1st. And I broke the shift linkage "shear" pin on the '69 Fairlane. Column shifters are the worst to try "Speed" or "Slap" shifting. Too much play in the linkage. That's why I quit "Speed" or "Slap" shifting those old "on the column" trannys.

The slow engine response to the lifting of the throttle means nothing when "Slap" shifting since you don't lift the throttle. It shouldn't be a problem for "Speed" shifting since you're out of the throttle just to keep from overreving the engine if 1) you have a slow shifter or 2) you miss the gear. The slow response would be a problem for "Power" shifting because it means that you have to want a long period of time for the input gear RPM to match the output gear RPM. During this time, you are coasting and losing speed.

Pre-loading the stick before "Speed" or "Slap" shifting is a must and is an advantage for "Power" shifting. Pre-loading shortens the time required to get out of a gear.

And, yes, you will <font color=red>grind</font color=red> the gears, when "Speed" or "Slap" shifting, if you release the clutch before fully engaging the next gear. You'll also <font color=red>grind</font color=red> the gears if you don't properly match the RPMs when "Power" shifting.

The only way to learn how to do any of these shift methodologies is by doing. (They don't make simulators for this.) You did the same when you learned how to "Granny" shift. Imagine how our "ancestors", who didn't have synchros, had to shift their manual trannys and you'll realize why "Double" clutching and "Power" shifting came into being.

how old are you suprhulk? my dad gave the same lesson to me about slap shifting. I've never heard anyone else talk about it before.

Put it to ya this way.

I was "driving" the '57 Chevy up and down my folks driveway by the time I was about 10 years of age.

My dad taught me how to drive in the '66 VDub before getting my license.

After getting my license, I used the Bug to teach myself how to:
1) Turn Doughnuts in the school parking lot.
2) "Speed", "Slap" and "Power" shifting and double clutching.
3) "Bat" turns. (Slaming on the brakes, sliding the rear end around 180 degrees and speeding off in the reverse direction).
4) What is now referred to as "Escaping from a kidnapper's/terrorist's roadblock" by backing up as fast as possible, stabbing the brakes and whipping the steering wheel in order to get the front end to slide around 180 degrees, shift from reverse to first and "get outta Dodge".
5) Burn rubber. Not easy to do in a rear wheel drive, rear engined, ~65hp car. However, It can be done.
6) Drifting, power sliding/steering.

Everyone knew this VDub. The townsfolk complained to the police about my shenanigans with the Bug. The city kittys and MPs use to follow me around just to remind me that they had their eye on me.

My dad bought the '69 Fairlane to replace the Bug (got tired of replacing the clutch I guess) and had it modified with a Holley 650cfm 4barrel double pumper carb, dual glass paks and a set of rear lifters (popular "redneck" mod back then). I called it the "Green Monster". I could "lite" the tires on this beast as easily as any pro-stocker. Looked like a smoke grenade had exploded. I thought it howling good fun to do this in the "General's Circle" base housing area. The Base Commandant was a real a**hole. He'd drive around in his VDub Station Wagon with a radar gun pulling folks over and "dressing them down" if they went 1 mph over the posted speed limit. The police and MPs knew the <font color=green>Monster</font color=green> only too well since the previous owner had done these mods to her before selling her to us. The townsfolk called the police again. I dropped most of my insane driving habits the night I passed a State Trooper at ~105mph. The friend I was chasing, he had a Mustang, went across a bridge into town and lost the Trooper there. Unfortunately for me, radio waves are faster than a car. I passed another Trooper racing toward me. I turned into what I thought was a subdivision. My next turn showed me that I'd gone around two corners of a triangle 'cause the 2nd Trooper was right there where I'd left him. Fortunately we didn't have any brews (after all, we were only 17 and not of legal age [img]/w3timages/icons/tongue.gif[/img]). I did get nervous when he noticed that we all had KaBars. He didn't hassle us about them. Since the Trooper hadn't gotten a fix on our speed and since carrying unconcealed KaBars wasn't illegal, he let me off with a warning. [img]/w3timages/icons/cool.gif[/img]

My '67 Camaro was only 3 years old when I graduated from high school. Bought it to drive around at college. My only mods were 1) moved the driver's seat backwards about 6" 2) added an 8 track stereo (with <font color=red>two</font color=red> speakers in the kick panels [img]/w3timages/icons/crazy.gif[/img]) 3) put G60/14 bias belted tires at all 4 corners (the front tires would rub the chassis if I'd hit a bump in a hard turn) 4) replaced the rag top when a friend accidently stuck a 2x4 through the vinyl rear window.

My age is buried in the above "travel down memory lane". [img]/w3timages/icons/laugh.gif[/img]
