997 Turbo - Engine Tuning
He had a lot of praise for the new VTG technology (of course ) but when it came to tuning, he mentioned a few things which I should share with you:
1. with the current setup, up to 540 HP or so are possible with tweaking the ECU software only, meaning an additional 60 HP. Torque would raise by around 25%. Top speed stays the same (which would indicate that the top speed is NOT electronically limited but limited by the rev limiter/gear ratio). This setup would enhance 0-125 mph/200 kph performance by 1.5 seconds (now don't ask me where he knows this from ).
2. the 997 Turbo engine boost pressure is already at a higher level but the chargers can deal with up to 1.4 bar without major problems.
3. (reliable) power figures above 540 HP can only be obtained with hardware changes, too expensive.
4. exhaust modifications which involve catalytic converter mods are not recommended due to the extremely high exhaust temperatures and the special cats used.
Just wanted to share this information with you, so we know what to expect from Tuners soon.
