Bad A$$!!!

All my friends know that I am a bit of a driveline geek. I am fascinated by exotic driveline components. Emco Gear, in Chicago, has been making racing transmission for a very long time. LG Motorsports has been using Emcos 6 speed sequential transmissions in their race cars for years. Well now, they installed that same setup in a street driven C6 Z06. Watch and drool. The price of admission is $24,500.

That is pretty cool.

Why does it look like he has to pull back awful hard to get it to up shift?

[dropit69]

Damn !!! that thing sounds like a JET !!

If I'm not mistaken he is holding pressure on it and speed shifting.

I imagine it's good on a road course as well.. I wonder how it is in traffic around town?

And will it fit in a '68 Camaro??? lol

I checked out their web site and they have a H-pattern 4 speed that looks like it would bolt right into our cars. In fact, the 4-speed is used in all levels of NASCAR.

It sounds like a jet because the transmission uses straight cut gears. For non-Corvette applications its even easier. Emco makes a direct T56/TR6060 replacement. It's a little less expensive than the rear mounted Corvette setup.

Here is another video that I really like. It is a third gen RX7 with a rotary that has been outfitted with a G-Force straight cut gear dog ring T5. You can see how well these transmissions work on the road course. This video is from Road America.

Now that I look at the videos it looks like he might actually be tapping the clutch on the upshifts. I looked at the Emco website and they mention an extra sensor package that would allow "no-lift" shifting. This tells me that the LG version does need to have the load taken off the input shaft in order to upshift. I bet they just barely graze the clutch to make it slip and thats it. The "no lift" (throttle) shift feature is available on some standalone ECU systems. There is a signal that gets sent to the ECU from the shifter handle indicating that an upshift is about to occur. The ECU will then momentarily cut the ignition for a specified amount of time (in milliseconds usually). This takes the load off the input shaft and allows the transmission to be shifted without the clutch and without lifting off the throttle. Some ECUs can also rev match the engine during downshifts so again the clutch does not have to be used and the shifts are very smooth.

I love it, that's freakin awesome.

[Vegas69]

Cool but not 25k cool unless it's NHRA. That handle is that long for a reason. Look at that guys forearm flexing.

Almost all teams in NHRA run the Liberty clutchless trans. It's only about $8K.

I would go crazy with the bolt rattling around sound that thing makes on the street.

I think that was the reverse shift level. Easily fixed.

The long shifter is pretty common these days in top tier GT race cars. From what I understand it's something of a matter of driver preference but the thinking is that it puts the shifter closer to the wheel for a shorter reach.
