i have a 2015 xf 3.0 supercharged sport portfolio , horsepower 340 torque 332 , what kind of power with a added pulley and exhaust

 

Horsepower 450 torque 520 Nm (383 ft/lb).
That's with a VAP (or Eurotoys) crank pulley and tune on an F-Type V6 (exact same engine as yours).
I suspect the F-Type exhaust flows a bit better than that on the X250 so without exhaust work you would probably get a little less but not a helluva lot less.
Plenty of hi-flow exhaust systems around for the X250 V6 including VAP, or just get your local exhaust shop to build you one.

 

what kind of price im looking at ,and do you no any shops in the east coast that does that kind of work

 

Around $1800 US IIRC for the Velocity AP pulley and tune.
I would point you at their web page if I could but here in Oz it directs me to the local rep (Scuderia) which is no damn good at all for you, but if you search for "Velocity AP" you should be able to find it.
And being in Oz I can't help you with US based exhaust shops!

 

thanks for the info first ill try exhaust and see if any power difference ,then ill try the pulley

 

A custom exhaust won't give you much more power if any, maybe 5-10 hp at the top end which you would struggle to notice.
But a crank pulley and tune, that's a whole other ballgame!

 

I managed to access the VAP web page you want: https://www.velocityap.com/product/j...ey-ecu-tuning/
I was a bit out on both the price and the torque, for the crank pulley plus tune it's $1939 US and the torque is 436 ft/lb so quite a lot more than I said before.

 

wow ,im going for the pulley. almost an extra 100hp, thank you for the info , i wonder if the transmission can handle it ,even though i wont launch the car

 

No problems with the trans, you have the same ZF 8HP70 as in the F-Type and heaps of us F-Type V6 owners have been running the pulley and tune for years with zero problems. It's not max power which can cause trans problems, it's max torque, and the 8HP70 is rated to 700 Nm (hence the 70) which is still a fair bit more than the tuned V6 puts out. Even then the Transmission Control Module (TCM) is very "Nanny tuned" and limits the available torque real quick if it senses danger, as it "talks" to the Power Control Module (PCM aka ECU) and tells it to ease off on the torque.
And in your case it's not an extra 100 hp it's closer to an extra 110 hp, 450 vs 340.

 

Thats amazing because i paid $13,972 dollars for the car ,the sticker price was $61,000 and ill have a 450hp car for $16,000


SOLD

 

found a guy who used a tuner device and made 100+ horsepower ,with the exact engine ,(f-type 3.0)

 

It's the Viezu tune using pretty much the exact same device/tool as VAP use (they call theirs V-Tech).
And it's the exact same procedure as the VAP tune.
I think he (or Viezu) is exaggerating a bit about an increase of 100 hp with just a tune, the VAP tune by itself takes the car from 340 hp to 416 hp (76 hp increase) and you need the larger crank pulley plus associated tune to go to 450+ hp.
If the Viezu tune by itself really does take it from 340 hp to 440 hp (which I doubt) then I would be a little worried about the safety of that tune.

 

i must look into it more

 

The Viezu web page says +80 hp for the base (340 hp) F-Type V6: https://viezu.com/your-vehicle/cars/...charged-340bhp
So not +100 hp and within the error margins of what VAP claim.
Methinks our friend in the YouTube vids is exaggerating a tad.

 

And for your 2015 XF (which by the way is an X250 not an X260) the Viezu tune adds only another 40 hp (not 80 let alone 100) and only 60 more torques (not 100): https://viezu.com/your-vehicle/cars/...6-supercharged

 

so to get to the 100 i need the crank pulley also
but then again with the tuner getting 60nm of torque is amazing

 

i think i would like to do this
