[UKBob]

Has this been done before?

I dont suppose anyone has the afterinstall results?

Will have a look later. Anyone got numbers to post on a standard 4.5? Not that Id want it personally Prefer the manual stick, but it does sound interesting!

I remember they were charging around 6.5k plus your box to implement the Zeroshift system....

boss cerbera isn't running zeroshift is he? damn like that car isnt fast enough anyway!

You should contact 350matt, he knows all about this stuff, top man.

He told me all about his beast on the phone once, never mentioned the shifter. Great for track-heads, I cant imagine an auto box being high on the traditional sports car enthusiasts list... specailly not at 6K!!!

I don't think zeroshift have actually sold any boxes to customers yet - it's still in a development cycle.

Last I heard they had abandoned all plans to convert existing boxes to the zeroshift system and concentrate instead on new OEM supply. Was a bit disappointed when I read it but I doubt it will be too long before we start to see the first systems on the streets.

I hope it comes through, I wander how much torque they'll be able to handle... I would have thought as its continuously hooked to the engineside there wont be any worries of shock-loading, but what about re-engagement in the box itself, gears must take a serious beating? say like helical dogbox gears...

I wander how much the patents must have cost, cos you need to register in the USofA and the UK and the EU right?

[ccharlie6]

try and get the issue of race car engineering which featured zeroshift, it was a really interesting piece

[bosscerbera]

ZeroShift has switched T5 development from the Cerbera to a new Mustang.

There is video footage, CAD animations and PDFs of the Racecar Engineering articles (Feb 2004 and June 2005) at www.zeroshift.com.

Shock loading - each gear will probably kick like a mule with a headache and hangover

With no clutch to absorb the shock loads - it will need something else after all consider :

engine speed must change : up or down (lets say 500 ~ 1000 rpm)
drivetrain speed differential
gear speed

Would you want a kick like that on a wet corner at near max traction limit..

If they solve that - I'm sure they will have a world beater or DSG

That is the whole point though, instead of the double spike that a conventional manual shift causes, delivered torque throughout an upshift remains virtually constant. I think they switch off the engine and then pull the revs down on the clutch, or something along those lines.
