Might be far more cost effective to retrofit those seats into your existing car (with the benefit of keeping the MT). I'd bet the mounting locations for the rails are identical.

 

Sacrilege and desecration of the car. It _must_ be factory and original.

 

You got it!

 

That's why I have an attic full of OEM parts for the next generation to return the car to stock.

 

If the new one is 400hp tired that means the tunes out for these only bump it up by 19hp?
I see the VAP tune is 419hp on any model V6 so they are only tuning in about 19hp increase? Maybe VAP will get a hold of this tune to see what the differences are and then revisit their tune for another bump in power maybe/hopefully?

 

Aren't the ratings net crank hp and your baseline dyno rwhp? If you got 367 rwhp, the car is actually producing well above the 380hp at the crank (net with accessories)

Your logic is correct, but the actual rwhp came in at 313. I had to make an assumption (though, a generally accepted one) that the powertrain loss is around 15%. That assumption could be off by a % or two, potentially putting the advertised number right on the actual mark. Thanks for bringing up that point.

Not sure if this was posted

 

Honestly, does 20 horsepower make that big of a difference?

 

I guess it depends on if they only bumped up the peak hp or if the new tune has more torque/power across the the whole rev range.

Dunno if you saw the dyno charts from unhingd's tune, but it was a big fat gain in the mid range, on top of higher peak numbers.

20hp on top of 375hp, yes I think you might notice it. When the WOT flap on the intake of my XJR failed shut and I lost 15rwhp (proven on a dyno) I certainly noticed it... The XJR is making more or less the same power as as these V6S...

None of these early press releases have given away any torque numbers, and no back-to-back test drives of a V6S vs a 400 yet, so it's hard to say for sure...

 

+1. If they did bump the torque by more than 25 lb-ft , that could be the reason it will not be offered with the MT. Too close to the nominal maximum torque specified for the ZF S6-45.

only difference the extra 20hp makes is in marketing


400 badge on car to the marketing peeps probably sounds better than just "S"

 

+1. Put the word Sport and a nice big round number like 400 on the car and it will be perceived as a HUGE upgrade / revision from the S. In reality its just a few more BHP and some badges.

 

Wait...367 hp at the wheels? Or the crank?
Cause at the wheels 367 hp could mean as much as 410+ hp at the crank, depending on your driven wheels (RWD/AWD) and the transmission. No?

Correct, see post #27 above.

 

bumping a semi-old thread here but...

Those of you with the 380PS F-type may shrug at +20PS, but for us XE owners with the 340PS engine, a 60PS gain would be very noticeable (slightly under 20% gain!). The prospect of flashing a factory-approved 400PS tune to the XE is pretty exciting.

are we sure the only power upgrade will be in the ECU?

Would we put it past JLR to have utilized either a smaller crank pulley or perhaps upgraded cooling? (if the intercooler is shared in V6/V8 engines, the latter would be pointless of course).

 

There would be no need for them to go with a larger crank pulley. The OEM hardware can readily achieve 420 PS with a good tune. 400 PS would still be a conservative tune for that engine.

 

Makes sense, and thanks for the correction.
