Scott - very nice video - thanks for sharing!! Make you want to go out and get a Hollinger or Quaife just to blast through the gears.

The covette sounds excellent. We are running the hollingers in our V8 Supercars in Australia this year i think. It would be in sane in my 68 BB Camaro

I'll have one in my race car one day.

PPG has released one recently with their internals, the shifter stick/base, which is based off of a production T56 BH/front bearing plate/case/tailshaft.

Their goal is to make it a drop in affair. Meaning you can run your existing clutch/driveshaft/trans mount. It will feature no lift shift and will blip the throttle on downshifts. I believe you must purchase a Motec trans ECU for this feature. Internals are rated at 1000hp. Target price is $16-16.5K for the internals not including assembly labor or the bare case. The T56 Magnum unit would be the preferred case due to the thicker case webbing (vs. the older pre '08 T56 case) plus it has a built in internal gear sprayer provision.

This would be for an in-line transmission like ones found in F-body, GTO, and 99% of the LS engine swaps out there. If your engine can run a T56 (Ford/Mopar) than this would work for your swap. Sometime next year they hope to release a paddle shifter setup for it.

Ratios of 2.437 / 1.611 / 1.228 / 1.000 / 0.875 / 0.777. Other gear ratios will be available once demand calls for it. While certainly not for everyone they offer durability, lightning fast shifting, no missed shifts, full throttle upshift and auto blip of the downshifts (using DBW throttlebodies). You start out by using the clutch to get things going and then it goes sequential style. The gears are billet heat treated Helical cut which is a 12* angle and doesn't whine as bad as straight cut gear sets. Also takes less engagement effort. The PPG rep I spoke with mentioned they had no failures to date running T56 style setups in under 1000hp cars. These gear sets are also used in 7 second turbo Vipers.

Overview from their website:

It is fully streetable and definitely designed with track use in mind.

Currently it is setup with a stick that is pulled (upshift) or pushed (downshift).


On a side note:
EMCO sequential transmissions are $25K+ and are problematic with breakage issues. Plus 50% more expensive. 600hp or so seems to be the reliable limit.
Quaiffe offers a sequential gear box with limited support and weak components. Don't hear of many behind V8's being reliable.
Hollinger costs more than the EMCO.... Closer to $30K.
Hewland also similar $$$$ to $30K+

This isn't for everyone... but it at least something to learn about as another option for the higher end builds.
