I was looking for more data from others experiences. My difference is 22.6 mph, was hoping to pick up more with my intake setup. Note, I do not have an f-body and I’m running a 4l80. Thanks

 

I backed 26 mph when I was running a pt4000

 

dayum. What was the 60’? I was hoping for 24-25.

 

60' 1.56

 

Usually an average of 55.00 MPH with a 4 plate and 3 floater clutch.

 

I think you missed the title/idea of the thread

 

Yup as usual, you would be correct :-)

I read that one half a sleep...

 

Bump for more info. 55mph is nuts.

 

55mph is what he gets in an alcohol car with a direct drive slipper clutch.
You won't pick up 55 with a 4000 stall off the shelf converter lol

That's why I said his comment was off base for this thread

 

Yup :-) MaroonMonsterLS1 would be correct, being that 55MPH is my 2002 carbon-fiber bodied Firebird Trans-AM.

It is an alcohol Funny-Car. It runs in the NHRA Lucas Oil Drag Racing Series Top Alcohol Funny Car class.
An average pass would be in the 5.4000s quarter mile at about 260.00MPH.
Estimated 3,500.00 to 4,000 HP

Our class does not use direct drive though... The faster class (Top Fuel Funny Car) does.
They run on average in the 4.0000s in the 1,000 foot races with an estimated 8,000 to 10,000 HP.
Currently best runs in Top Fuel are in the 3.5600s range at over 335.00MPH.
That would be done via direct drive (NO transmission, just a clutch and solid drive-shaft ***more of an axle really***).

My car runs a 3-speed Lenco transmission with a clutch.
The clutch is only used to launch the car or to stand still.
No clutch involvement for shifting.
The Lenco is not an automatic transmission and not a manual transmission.

To put this simply and not very accurately...

Image an automatic transmission with no valve-body.
It is a modular transmission. It can built as a 2-speed up to a 6-speed by adding modules.
Each module has a clutch pack, a sprag, and a planetary gear set.
Basically the 3-speed would be the "core" rear most of the transmission which is a coupler and planet assembly which is used to select forward or reverse gear ranges.
Then each module added would add another gear. There are 2 modules added to the "core" to become a 3-speed.
Each module has linkage to apply the clutch pack and planet assembly inside.
Each module starts with the planet assembly in gear reduction mode.
When the linkage to a module is engaged the clutch pack applies and puts the planet assembly in 1 to 1 mode.

Some drivers have a shifter to move all the linkage.
Some old-school guys have a shift lever for every gear (module).
Most guys in our class have a pneumatic system.
We have a button on the steering wheel for second gear and another for third gear.
The buttons release compressed air which move an actuator, which moves a small lever for each gear (module).
