What happens in the transmission when you double clutch / Heel Toe Downshift???
Trying to do everything in one take is nerve racking, as it's nearly
impossible to do perfectly. Minor corrections: I said the clutch pedal and
throw out bearing are not wear items, I meant not high wear items, compared
to the clutch disk. Also, when I mention buying a cheap car to practice, I
mean if you own a manual transmission track car that is not your daily
driver. Finally, I didn't talk about the syncros. You can do this with
one clutch pedal action, but you make the syncros speed up the intermediate
shaft. When you double clutch, you bring the intermediate shaft up to
speed with the clutch disc, which has more capacity to do so than the
synchros. Minor point, but you will see prolonged synchro life when you
double clutch. Also, it is not the mass of the servo or engine but the
power created by electricity of gasoline that is responsible, but the mass
is responsible for the inertia.
Why I love a V8
Torque is so much fun. To put this in perspective let me give you some horsepower numbers.
At 3000rpm I am only making about 165whp. and at 4000rpm I am making about
about 235whp. Not a big amount of horsepower. But at those
same RPM's my V8 is making 290 tq and at 4000rpm I am making my peak tq of
310. So while my hp is down my car still accelerates fairly briskly. God I
love a V8.
Best GTR launch control reaction ever
Courage is strong in this beautiful GTR Pilot! She took the directions
given to her and just rolled with it!
I love the part where the fear takes over body control, which makes it hard
for her to think straight to let off the gas to make it stop. Hahahahaha
This is by far the best GTR Reaction I have ever seen with for GTR Launch
Learning to Power Shift
I am trying to learn to power shift my 1993 Mustang. I have mastered power
shifting from 1st to 2nd and 3rd to 4th. As you can see and here in the
video, I have yet to master the 2nd to 3rd shift.
UPDATE 2 Below...
here's my video on autoblog:
UPDATE 1: by "perfect shift" in the title, i didn't intend for it to really
mean a best-practice way to shift gears but, rather, to mimic the title of
the thread i read about this technique from.
this is a video i made after i read a thread on the forum i'm always on
(forums.clubrsx.com). it's about shifting w/out using the clutch. yes,
there really is less wear on the infamous synchros (a widely discussed
topic in the comments section of this video) the closer you shift at the
appropriate RPM for the gear you're switching to.
UPDATE 2: i've turned off comments and ratings to this video. i'm pretty
much tired of seeing the same comments recycled. besides, there are already
over 1000 comments (after removing extraneous ones) and over half a million
views. here are the categories the comments fell under and my responses to
comment about "facepaint"
-it's a mud mask used for exfoliating. i didn't bother to take it off
before making the video, apparently.
truckers do this
-great. i learned something new after receiving this type of comment about
my car is gay
-it's a matter of preference, homies ;)
i tried it and it worked
you're messing up your tranny/synchros
-i'll agree with this to a certain degree. you will mess up your
transmission/synchros if you perform this "clutchless shifting" horribly
(i.e. bad rev-matching) and repetitively.
why don't you just use the clutch?
-see update 1
Launching a Manual Transmission Car
Quick and dirty vid taken on the way home from St. Cloud. I am in no way
shape or form condoning driving a vehicle in an unsafe manner. I took this
video in a safe location free of other traffic or pedestrians.
How not to do a burnout
My first real attempt at a manual trans burnout. 1st gear, totally choking
going for 2nd gear.
Race Car Driver & His Footwork
Check out the amazing footwork working the clutch, brake and gas all at the
same time with both feet. Look how quickly he shifts up and down and
impressive heel-toe action.
