Bret have you played with setting the P/N rev limiter in HPT? I tried it and didn't like it for day to day driving because whenever I touched the clutch it would cut the RPM but I think if you moved the clutch inhibit switch down lower it would work better and essentially accomplish the same thing as the LPE unit.

It kills whatever method you tell it to for the rev limiter overall. Spark, fuel, ETC. Any of these can be disabled or enabled. I use both the spark and fuel methods although I do not use it for a no-lift or two step.

Actually it doesn't show it in that vid, but I think Rob used the launch & shift off the 2-step.

Bret, the two step is nice for setting launch RPM, but you really shouldn't need anything for non lift shifting other then a quick hand and a 100 rpm window. Since I jump in and out of different cars all the time, I just practice in the staging lanes by going through the gears many times with the car off, then by the time your actually rowing threw the gears its just muscle memory.
Practice is free.. (taking a tenth off per shift is priceless)

I can't watch that enough. Doesn't that have some sort of "slipper" clutch and a face-plated tranny?
I think that might help me get down the track faster.

No lift shift module
This isn't in a Corvette but here is a video of our no-lift shift module (LNC-TC1) being run in our Camaro.
Link to in-car video on YouTube.
Link to longer video from our track event. 1st two passes show the in car and then an external shot from the vehicle. Long video.
Our LNC-TC1 uses a load cell input (from a load cell shift **** etc.) to trigger the torque cut on the gear change. It is designed for use with faceplated, pro-cut and dog-engagement type transmissions to allow clutchless no-lift shifts.
We have a few that we sent out for in-vehicle testing but we haven't released this product to the general public yet but should be doing so soon.
Regards,
Jason Haines

Great video!
So that's a tricked out trans? I was wondering. I've seen the bikes with the torque cut modules, allowing them to shift clutchless, but I'm guessing they have straight cut gears as opposed to our helical cut.

My LNC-002 is set so it will hit between gears but it never does anything more than maybe 1 loud pop (if its real hot). I put it in for launch control and I felt better controlling it off of the clutch pedal than the line lock so its always there, even if I were to forget to engage roll control at the line
At your power level, there's got to be some concern of the surge of power from no lift shifting between gears breaking the tires free. That's another puzzle to solve entirely, something like what Lingenfelter just showed may help with that. I let my progressive nitrous controller do it for me
Edit: Get a good shifter ASAP. It makes a BIG difference.

That car does have a slipper clutch and face plated trans, Tommy- our in house trans builder built that trans for Rob. It was/is to my knowledge, the first face plated C5 set up yet. Pretty innovative stuff.

Shifts
We are actually seeing less unloading/loading of the suspension and smoother acceleration with the no-lift shift than we did with the clutch type WOT shifts. On earlier runs you could really see the suspension move up and down during the shifts, even in the videos of the runs. Very obvious from the shock travel sensors. You can also see the difference in the acceleration rate during the shift. I will find some graphs of the acceleration versus time/speed and post the data.
FYI - we are running a RPS triple plate carbon clutch and then a RPM built dog engagement gear set (made for us by Liberty). RPM Transmissions has some nice pictures of the transmission shown in some posts they did. Our car is 4200+ lbs and 1250 rwhp.

I know Rick (RKT56) did a faceplated transmission for a C5 a while back with a gearset from Liberty, but that was well after Rob's car.
Running a slipper clutch is not for the faint of heart and does make the car quite a bit more 'track oriented' but they can be made streetable. But don't expect to just set it and forget it. It requires regular adjustments at the track (once you figure it out, its not too terrible -- coarse adjustments on the pressure plate, fine adjustments via chassis and tire pressure) and if you're driving it on the street, it will require adjustments between street and track. But, with the right equipment, it can be done.
Let me be the first to say, a slipper clutch absolutely, positively will *NOT* help a car with severe traction issues going down the track.
While we're busy talking hardcore, does anyone know of someone that has tried a Pfitzner (PPG) dog gear set in a Corvette?

The Pftizner product is 22 degree helix angle - not straight cut - so it is fairly quiet under load. I drove my RT6 equipped sports truck over 1300 miles round trip to the PRI Show Orlando for the media folks to check out.

MTI Racing (www.mtiracing.com), another sponsor here, has run several of our Road & Track 6-speed with the Pfitzner gearset. They are doing well with it - they set two Texas Mile records already. Look them up here and on their website.
