you suck at a 3 -> 2 downshift and you’re gonna sit here and tell ME how to drive a car? Fucking laughable. Learn to think on your own, not do what truck drivers do.
You do realize the shear amount of weight they carry right? And the fact that the braking system on a semi is WAYYYY different than the hydraulic system in your car right AND that the clutch/transmission setups are completely different as well?
rev matching is the best way to minimize syncro and clutch wear. I drive heavy trucks by shifting without clutching (esp unsyncronized transmissions), but honestly in syncronized transmissions its hard on syncronizers even if it doesnt grind. Double clutching is not nessesary on syncronized transmissions but it will be easier on the syncronizers than regular shifting. If you are skipping gears on say, an upshift, say going from 2nd to 4th, you should go into 3rd momentarily then to 4th before you let out the clutch, it will be much easier on the syncronizers. Also at red lights, put the car in neutral and take your foot off the clutch, the thousands of pounds of force on the engines thrust bearings is not a good thing to do continuously if you dont have to.
OMG, an 8 lb. flywheel really? I had the same shit, and a pretty aggresive clutch on my turbo hatch too.
It’s not THAT bad. You are just a little bitch.
I still would love to hear your explanation on the whole semi truck/ “allison 6speed” argument. Hearing this apples to oranges explanation should be good.
And by sucking, it means that it is not as smooth as a 5-4, 4-3, because you are in a HIGHER rpm at a LOWER speed and there is more movement because of this. :picard:
I said that I do not engine brake because I believe that it puts undue stress on drivetrain parts. It is my belief that brakes should be used to slow you down, engine makes you go.
Post facts as to why the engine braking stress is negligible or GTFO.
that is EVERY post of yours in this thread, all you did was spew hate
it’s important to note that conversation is was started in reference to a conventional 5/6 speed transmission. I don’t give a shit about semi trucks, I don’t drive one. I have never heard of an “allison” transmission. I am just going to assume it is some sort of dogbox, which are all built differently than a traditional transmission.
The OP drives an F-Body. Engine braking will cause more harm than good. Don’t ever do it unless driving conditions (like snow) prevent you from applying the brakes as hard as you might like. Sometimes braking the rear more than the front will put you into a controlled slide (drift) instead of an uncontrollable slide… which more braking will make worse. You will not be able to steer if the front tires are locked up.
Rev matching is always healthier for your transmission than not. Not something you need to practice or even perform on a regular basis. If you’re about to roll race on the 990… and you’re getting up to speed in a taller gear and want to maintain your speed but pick a shorter gear, rev-matching should be used here.
When towing a heavy load truckers often use their engines to assist them in slowing down by engine braking. Your typical pickup truck does not have the proper hardware for “safer” engine braking, though they can still do it with minimal harm to the motor or transmission. If the vehicle is equipped with the proper hardware, like an exhaust brake, they can generate over 100hp in braking force, just from the engine. Essentially turning the motor into an “air pump” (as if it wasn’t already) that takes the rotational force of the drive axle and uses it to force air through the motor, instead of the combustion stroke. Pulling a large load and trying to stop with only your brakes is stupid and dangerous. Brakes can overheat and fail completely. Your motor, even if it overheats, will still perform as a brake in a stopping emergency.
The only reasons I’ve ever engine braked in a small vehicle with no load was to compliment shitty brakes, lock up the rear end to induce a slide (no e-brake) or to troubleshoot particular drivetrain problems.
Why are we locking up the rear with engine braking… Even going from 6th gear 67mph to 2nd gear 8K rpm… the rear end won’t lock up when you rev match…
Seriously, if you really think there is any bad to downshifting and rev matching you are clearly retarded. There is no harm involve from just down shifting, rev matching and coasting down.
