Hello Guys

Have anywhere Some Infos for me? A tuner in Germay sell a PowerShift Box for Porsche Cars.

where can I buy this? Costs?

 

How can you power shift these cars without eating the syncros??

 

i have no lift shifting in my tune but too afraid to use it!!

 

I also have it in my tune, And always hold pedal to the metal when banging the gears while having fun, But I still use the clutch.
If I am not mistaken the whole point of it is the RPMS don't creep up in-between the shifts with it..

 

Hello

For the PowerShift you need the clutch. But without releasing the gas pedal

 

shift box (4950 Euros)

but with all this systems you must use the clutch.....

 

For those with it in their tune, do you know how it works? Since it is throttle-by-wire, does it very quickly close and open the butterfly while you shift? Or does it cut ignition while the clutch is depressed?

If its the latter, that would be pretty cool. Then the throttle doesn't close, and the boost that you had built up doesn't get puked out the DV's = you don't have to build boost again in the next gear.

 

I know it was quite a while ago now, so my memory might not be 100%......but didn't both Sean and Chris eat their gearboxes with power shifts?

 

mine is an epl tune and from what i understand it cuts timing to allow the shift

the gas is keep full on and the clutch is used. i havent tried it yet as im worried about missing a gear and hurting the trans

 

With that feature it will not put any more stress on your transmission if you use your clutch Because you would be unloading the transmission when you press the clutch pedal down, disengaging power momentarily to let you shift.
It's just wears the clutch quicker, as I am on my 3rd one.

 

my concern is more about the unatural way this for shifting a manual and possibly missing or badly grinding the gears.
on a bike i use my hands to shift. on a big rig i only use a clutch to get started then shift 10 gears without any clutch at all. using the car its a normal gas clutch setup. keeping my foot mashed on the gas and then using the clutch doesnt feel natural and causes a hesitation on my part.

 

I've done a lot of drag racing in various cars, no lift shifting does gain you about 1-2ths on a 10 second car if you hit every gear perfectly. If you're not at the drag strip trying to wring out every last ounce of speed, don't bother with it.

 

i was born with vht in my veins and burnt rubber fumes as cologne! drag racer at heart!

 

Actually IF it was possible on our cars,,,I would shift like I shift my bikes that don't have electronic kill shift kits, which is wide open and backing off the gas a hair so to unload the trans enough to hit the next gear,,,all that with out using the clutch,, That save the clutch big time....
I drive the Mack fire engines like that also..LOL..

 

air shifter ftw!!
