F-type V6 S BHP
Discussion
I think that is all that you can do at this stage. There may be some simple explanation for what the rolling road is showing. There is a difference between running on a rolling road and running on a physical one. The engine management system on a modern car probably knows that it isn't really moving, the air flow is different this could affect the intercoolers and even the ability of the car to breath. No idea how my XK150 would react (so in no way comparable with an F-Type) at the moment, badly I suspect that even with the fan cooling the radiator and so stopping the engine over heating the lost of air flow around and under the car would probably result in the carbs getting too hot quite quickly.
I'm intrigued so please keep us posted.

Has anybody driven back to back the regular v6 and v6 s? Ie can they feel the extra top end urge of the v6 s?
I have. The S definitely felt quicker, but not massively so, I could definitely have lived with the standard cars performance, though I'm not a speed demon.The biggest difference I noted between the two was the handling, which the S feeling much more supple and controlled thanks to the adaptive suspension and the LSD. The standard car was fun, but a little bit too old fashioned muscle car handling wise for me.
Then again, what do I know, I decided to buy an Evora instead!

There's a 10% difference in the Differential ratio, so the S is always going to feel perkier.
After looking at the shape of both Torque curves, I'm going to guess the bypass valve is leaking boost.
Would be interesting in that case to see if a pressure test could somehow be conducted as a leak will affect it hugely.After looking at the shape of both Torque curves, I'm going to guess the bypass valve is leaking boost.

If the bypass valve is electronically controlled, rather than just using vacuum, there will be a pressure transducer that can be read. Whether the OBD lets you look at its output is another matter.well ours appears to be in very good health according to a very surprised guy in a f type V8 !!!! much as he tried he could not shake me off his tail in the end he pulled over for a chat and was pretty impressed with the V6S .
What sort of mileage have you done , ours has done 13000 and feels to be bedding in nicely .

Perhaps you were a better driver than him??What sort of mileage have you done , ours has done 13000 and feels to be bedding in nicely .
My cars done about 12000 miles, and Ewolgs has done around 3000 I think.

This might explain my surprise and delight when I took on a V6S a few weeks back expecting a close run but ended up trouncing him in my old XJR despite him clearly trying very hard (judged by the full use of revs and roar from his exhaust)
The V6s is very much like an s2000 that I used to have many years ago. Not that it's gutless low in the rev range because it's not, but you really have to be in the right gear for it and rev it out. Any gear from any speed sounds loud (even a accelerating to 30mph in an F type with the exhaust activated. He may not have had it in sports mode on the gear box. I've never even tried that in auto, I always use the paddles when in sports mode with dynamic mode activated.Lots of different factors.
Jaguar are taking Ewolgs car back to the factory for between 14 and 21 days to investigate. After his has been they wanted to see mine. I'm not prepared to wait near on a month for them to take my car for another month. I'm not actually driving my car so as to not put any mileage on to it. And its the summer, the time of year that we all wait for to drive our cars! I want to replace the car with a V8. Jag have agreed to this, I'm just waiting for a call today to find out what they can do for me. Jag head office have been very helpful and understanding. It should be mentioned that my car has not just got the BHP issues, its been back to them 5 times for repair in as many weeks.

Appreciate that, but I wasnt in sports mode and he was definitely giving it some stick, fast cornering powering out and pushing on hard. I did feel like pulling up next to him and asking him what was wrong with his car I could see him looking at me in the mirrors , probably wondering how it was possible to have an old XJ welded to the back end.....Lots of different factors.
