Re: need imput on exhaust and power upgrade
We recently had the chance to drive a factory 997 Turbo.2 PDK in comparison to two tuned first gen 997 Turbo (RUF and Techart, both with power claims around 550 to 570 hp) and one tuned second gen 997 Turbo (tuner asked me not to mention his name, guess why) which claimed to have 580 hp.
From 0-100 kph, the factory Turbo was 0.1-0.2 seconds faster than the tuned first gen Turbos. From 0-200 kph, the factory Turbo achieved the same time as the tuned cars, in one case it was even 0.2 seconds faster.
The tuned second gen Turbo was 0.1 second faster than the stock Turbo from 0-100 kph and 0.2 seconds slower from 0-200 kph. Car was equipped with wider rear tires and some sort of an aero kit with a larger wing in the rear, this is actually what the tuner claims has made this car slower.
Bottom line is: There was no real performance gain here, taking in consideration the hp gain claims/numbers.
Btw: All cars were subject to TÜV certification, thus completely street legal, incl. exhaust emissions.
Comparing the new Turbo S with tuned 997 Turbo, things look even worse. So far, I don't know any tuned 997 Turbo to accelerate faster from 0-100 kph. 0-200 kph times are usually in the 10.3-10.6 seconds range for tuned 997 Turbo (570-620 hp) but the factory Turbo S usually does 0-200 kph in 10.0 seconds flat.
Do you see a pattern here ?
Of course tuners can change boost pressure to certain rev/speed levels but I doubt that this will be good for the car's reliability and since a 997 Turbo engine, especially first gen, costs a fortune...
This was really my last post in this thread, I promise.
