Well we know a tune and x pipe can get us to 550, from the XFR to the XFR-S so I'd say add a pulley and more efficient intercooler heat exchanger to that and 600hp should. Be real close.
As far as intakes the description given is pretty much the Twin cities performance intake I have.
I'm probably going to do water/meth injection along with my other mods and I should be over 600 at that point and still be very drivable. Not going to change the tune to be dependent on it though just in case I run out.
Will do another dyno run before to see where I'm at first and will report back when done.

Twin cities intake......ok will check that out although i have allready drilled my airbox and removed the intake silencers so not sure if it will be a huge benefit for me.......

cheers guys
What do you mean when you mention drilling the airbox? Is it a mod like the one bigcat posted from the mercedes board?
Yes mate........drilled 5 x 35mm holes in each airbox to allow more air flow.......to be honest i have no idea if it REALLY needs it, but my thoughts are that it's at least less restrictive than the standard air box.
You just need to take care where you drill the holes as there is a hole at the bottom of each of the boxes that opens out to the wheel arches......u don't really want any open holes over this point as all sorts of crud and rain water could make its way to the airfilter...........this set up gives more induction roar and supercharger whine.
The pulley is a crock or crap. Its almost impossible to remove. Just as hard to put back on. I heard the power gains from that mod is not even noticeable. You can easily damage your car. I would do the tune to remove the top speed limiter and get an extra 40hp but I don't believe ecu tuning group can even get that much hp with their tune. its not about spending money, its about spending money on something worthwhile. We need someone to come out with a great cold air intake system and a really good tune that will really provide some seat of the pants difference. Bigcat said he doesn't even feel a difference. That means something to me.
I know this is an old thread, but I have the Mina pulley and it made a HUGE difference. I also have a tune and K&N filters. I regularly dominate the new 5.0 mustangs on the street.....it is worth it. $275 for the pulley and I had a guy install it for $250. Best $525 mod you'll find.
I have the XF Supercharged 5.0 with an XFR tune and the pulley.

Results? Did the mist work well? Who did you have do it?
Decided against it after my last dyno session. Power did not drop off after multiple runs and I don't want to complicate my life with adding water meth solution and the extra plumbing.
And I make over 500 at the wheel now. It's enough.

I looked at the MB link he posted and don't really see how it pertains to our cars. When I took apart my filter box, I saw that our "trumpet" is already fully rounded. I got the impression from that post that the problem had to do with the flat spot.

i have a 2011 jaguar xf supercharged my best 1/4 12.2 @122 on street tires. No tune yet
sorry i couldt find it all i could find was this slip.it was a hot day at 4pm. After this run a week later i came back for test and tune with some ethanol mix around e30 and thats how i got the 122. Next year ill be back on some 17inch slicks

your 1/8 mile is 1.3 mph faster than my car with pulley and tune on a 1.96 60'. my quarter mile ET for that run was 12.47 @ 113.29.........
my next run was better with just a 1/2 mph better than you in the 1/8 mile on a 1.99 60'. my quarter mile ET for that run was 12.33 @ 115.53.
i wonder how are you getting all that mph without a tune? the only 4 door jags i've seen with that mph are 8 speed trans cars or 2 door jags can run pretty fast

yeah my top speed is really good. Is your car tuned? My 60 foot is really bad my best was a 2.0. I have a friend with a 600hp f10 m5 he runs 123-125mph at the 1/4. We raced from a 50 roll -140 and he only got me by 1 car😂

yeah, it's tuned
before tune was a 12.7ish at 111ish mph
after tune is a 12.4ish at 115ish mph
i have not done x pipe just yet. i remember seeing on your youtube you have the custom intake and the x pipe - did you remove the cats? what else gets your car that much more top end? my track has an elevation of only about 900' above sea level so i don't think the air is to be considered thin
