Bentley Continental GT Supersports performance tuning advice
Discussion
Hi Everyone,
This is my first post on PistonHeads although I've visited these forums for many years
I recently traded my old 2007 Bentley Continental GT in for a 2011 Supersports. I did a 4x4 Dyno power run on the old car before trading it in, it was completely stock and still pushing 475Bhp (520Bhp new).
The Supersports feels worlds apart performance wise but a recent power run only clocked it at 533BHP & 640Nm torque (as per attached image) whereas it is apparently meant to be 621Bhp and 800Nm new. The car only has 25K miles on the clock. The guy at RGS Motorsport actually thought that was pretty good and claims he's never seen a Bentley clock anywhere near their claimed numbers........?!
So a few questions for the community:
-Is the current power and torque what one would expect of a Supersports of this age and mileage?
-The car is currently totally standard, is this a good foundation to build on and if so what performance upgrades would you recommend and in what order or priority?
I was thinking something along the lines of a BMC Air filter upgrade to improve the air intake, secondary de-cat to improve turbo response and a performance remap?
Thanks in advance for your advice!

Right so BHP versus WHP. How well does the 553WHP compare as a ratio to claimed BHP?
Edit: after some further reading on Dynos it seems the WHP information a dyno run provides usually reads around *15 per cent less than the power measured at the engine (BHP) - this is because power is lost in the drivetrain (including clutch and transmission).
Four-wheel drive cars like the Bentley actually lose between *20-25 percent of their quoted BHP figure because of the increased friction.
So it would seem like the Supersports is actually performing far better in terms of WHP than would be typically expected.
Any advice on improving performance?

Wow that really does sound fantastic!
I noticed the Supersports already sounds a lot better than my previous Continental GT but the Quicksilver sound is really something else!
I will certainly upgrade the exhaust system. Does yours have the secondary cats removed too?
Did you ever have yours remapped?
