2002 Camaro Z28 with a Yank PT4000 torque converter
Normal driving in my 2002 Chevy Camaro Z28 to show how loose it
is with a Yank PT4000 torque converter. It also has 3.23 gears, Kooks LT
headers and off-road y-pipe, and Magnaflow catback. There are a couple of
WOT pulls about halfway through the video.
Torque Converter Selection - Summit Racing Quick Flicks
What does a torque converter do? A torque converter is a fluid coupling
device that transfers power from engine to transmission and multiply the
torque being created by the engine.
There are three major components that make up a torque converter.
The Fluid Impeller is the only part of the torque converter that is
physically attached to the engine. The impeller creates fluid motion within
the converter to create a transfer of power. The Stator redirects fluid
flow towards the impeller. The Turbine Assembly transfers the motion
between the engine and the transmission. Another important aspect to
understand is Stall Speed = RPM when the engine sends all available power
to the transmission.
Torque converters have 2 different types of stalls that they can produce.
The 1st type is Foot Brake Stall. Foot break Stall is an inaccurate way to
measure torque converter stall.
Flash stall is the actual stall of the torque converter. Flash stall is
always listed in range which is determined by different attributes such
vehicle weight, gear ratio and tire size. The flash stall rating is the
only true and most accurate stall rating that you will find on a torque
A few rules of thumb to take from this video are: First select a converter
that stalls at 500 RPM higher than the camshaft. Converters installed in a
big block engine usually stall 300 RPM higher than a small block. Choose a
converter that will stall below the highway cruise RPM. For additional

Dodge Charger stock torque converter stall speed test 2 - foot brake flash
Dodge Charger and challenger - R/T - R/T Road and track, Daytona, Srt8,
seem to come with a stock 2400 stall torque converter, In This test the car
is at full throttle and the brakes are holding it back completely, I must
say its a little tricky to determine the maximum foot brake stall speed,
you must flash it up a bit in order to get a true result, or it will seems
to lock up at a lower rpm, If you just do a flash stall test, "with no
brakes", it seems to lock up at 1800 rpms, its the systems (EMCC) hard at
work here, its designed so that it does not flash all your shifts when your
just crusing around, so its almost like putting the car in race mode with a
few rpm rev's, you have to tell it, hey - wake up, I want you to launch me
like a rocket.
You've probbably noticed this in regular driving, after you floor it once
or twice the car really wakes up, shifts quicker, and even holds your down
shifts a lot longer for you, boom - race mode.
After doing the stall speed tests and letting her rip, the transmission
held my gears for a long time as it was shifting down, back into
cruse mode, the transmission actually stayed in 4th gear till I got to
the lights, which was 3 miles down the road, normally it would
shift into 5th gear for crusing.
The system monitors the transmission as shifts occur and adjusts the
hydraulic pressure as needed, this five-speed transmission also uses an
Electronically Modulated Converter Clutch (EMCC) to control torque
converter clutch slippage, the charger's transmission uses highly advanced
electronic shift controls, this transmission is on the 5.7-liter 345 cu in
v8 HEMI EZB MDS in this video.
The transmission model is a W5A580 - 5 speed.
The two basic ways to determine your stall speed are "flash stall" or "foot
brake stall", flash stall is when your at idle and you just floor it, the
torque convertor will slip to a given rpm speed and then it will couples up
and engauge, to thust you forwards, that rpm is your stall speed, its like
letting your foot off the clutch petal at a higher rpm, or dropping the
The second way to determine your stall speed is foot brake stall, at idle
again, you put your foot brake on full and ease the gas petal to the floor,
to bring the rpms up as high as it can go untill one of two things happen,
one your foot brake will hold back the full power of your engine and you
can take that as your stall speed, or two the brake will not be able to
hold back the engine's power and the tires will start spinning, at that
braking point is your stall speed.
Now with the new electronics and system monitors, I find i can get a higher
stall speed by holding the brakes full and instead of just easing the gas
petal to full throttle, I rev the engine a few times while brake is on
full, and quickly try to get to a higher rpm.
I call it flashing up the torque convertor, and it seems to work.
So can I call this method a - "Foot Brake Flash Stall" - or did I
just invent this term.?...(grin).
This car is basically stock, Aem cold air intake and muffler delete, it has
stock two piston brakes, and stock 18 in tires, a year later they came out
with 4 piston Bremo brakes, with a 20 in tire option, for this model, if
I'm not mistaken.
I would really like to hear from people that have better upgrades,
and if they can hold it back with more horsepower. Maybe someone
knows how to fine tune the torque converter.? electronically of course,
The 06 Charger R/T - R/T in this video is full throttle at 2400 rpm stall
But don't worry I'm not done yet ... you just know I'll do my best to
flash it higher, I'll let you know if I can brake 2400 stall speed
with the stock torque converter.
One last thing, I hear there is a stock 1200 or 1500 stall torque converter
on the 3.5-liter V-6 and the basic R/T's...hum...I bet I could get her up a
few more digits...what do ya think...? After all, I heard
storys that this car only had a 1600 - 1800 stall to a 2000 - 2200
