997 Turbo Sports Chrono?
Discussion
Could someone tell me how this works. I understand it gives an overboost for a short period of time (10 seconds I think) but how is that time calculated ie is it as soon as the button is depressed or 10 seconds from full throttle or something else. Then once you have used your overboost how do you get more? Sorry if this is a bit of a dumb question but I'm interested to know.
Turn on Sport Chrono
Basically when you you plant your foot to the floor and have WOT (Wide Open Throttle) it will give overboost for a max 10 secs
So you could be in 2nd and plant your foot and accelerate for 3 secs to redline in overboost, change gear to 3rd and still have 7 secs of over boost etc
Not sure what the reset time is before it can be used again tho

Am i correct in my understanding that this is only activated after you reach 3000rpm too

"When ‘Sport’ mode is selected, the engine management system creates a much more aggressive response to pedal inputs. To do this, it implements an alternative throttle map which relates the pedal position in the footwell to a wider angle of opening in the throttle body. In higher gears, it uses a hard rev-limiter to protect the engine under power.
In the 911 Turbo models, under full acceleration, the maximum boost pressure in the lower and medium speed ranges is now temporarily increased by approximately 0.2 bar. As a result, engine torque is boosted by 50 Nm to a maximum of 700 Nm for a limited period. (The 911 Turbo S models are configured to operate with a higher boost pressure level, which means that their maximum torque is always 700 Nm.)"

Still finding references to it but between the rpm i first thought
Sports Chrono Package Turbo option
The available Sports Chrono Package Turbo provides the choice of an even more sporting set-up of various vehicle functions, including engine and Tiptronic S management, and profiles of the Porsche Stability Management (PSM), Porsche Active Suspension Management (PASM) and Porsche Traction Management (PTM). The option also brings overboost.
By hitting the Sport button on the center console, the driver engages overboost. This briefly increases turbocharger pressure when accelerating under full throttle. An arrow in the turbocharger boost display informs the driver that the car is in overboost. This additional boost of turbocharger pressure is achieved by adjusting the turbocharger blades to increase maximum turbocharger pressure by approximately 2.9 psi (0.2 bar), in the engine speed range of 2100 to 4000 rpm. The extra high level of turbo boost lasts for about ten seconds allowing the driver to confidently execute a fast maneuver.

hi carl, can OPC remap the ECU ? any idea of cost ?
On my car you see a '+' symbol appear at the top of the boost gauge.
You really need to nail the pedal to see it though (and be in the right gear).
A simple ECU remap makes it permanently available on the Gen2 turbo, like the Turbo S.

Remap should be good for around 560BHP without upgrading the exhaust and filter. Remap does around 600 BHP with these upgrades, depending on the climate you might need to swap the intercoolers for GT2-RS items.
