I brought my 2015 V8S to Orlando Jag this morning and the service manager asked me if I was interested in doing the "Performance Upgrade" which included the SC pulley and tune (not sure what if anything else) which would bump the HP from 495hp to 600hp for $2,200 and would not void the warranty.

He also said his personal F-Type is going to be the test mule for VelocityAP to test a new something-or-other that would bring it up to 700hp?!?! I said that would be awesome in the AWD R but would be more than a handful in the RWD S. When I asked him about needing to upgrade any of the internals, he said that the engines were tested up to 850hp.

Thoughts on this? How much more is this than doing the pulley and tune yourself? Would you pay the difference to maintain the warranty? Audi dealers used to install a supercharger kit made by Stasis on R8's which didn't affect the warranty either.

 

That's a bargain for pulley, tune, installation and warranty! You can't beat that. Is it a VAP tune?

 

I'm a bit surprised.......I could see them offering the 575ps SVR/P7 tune with no hardware changes and keeping the warranty (though I doubt JLR corporate would be supportive). I have the V8S and the Velocity AP tuner and plan on running the 575ps software.....personally I'm not going to bother with the pulley change for the extra 25 hp or so. BTW, the "495 hp" engines are actually running 510PS JLR software so keep that in mind when boosting the power as the results may not be quite as dramatic as you'd otherwise believe.

As far as power in the S goes......AWD is nice but there are many cars that are RWD with lots of power (Z06, Viper, Hellcat, etc.).....though you'd need to be a bit more circumspect with the throttle at times.

I agree. I just got this car and the rear tires aren't new so she tends to get a bit squirrely as she sits now. I might be more inclined to do the upgrade once I get some new tires but these will probably last me until summer. If I've gotten used to the power around that time, I'll definitely be looking into this upgrade.

 

Unless there was some sort of agreement with Velocity AP, there is no way JLR corporate would be onboard with this. My guess is that it will be a dealer-level sponsored warranty.

 

I am with you on this. Why would JLR sell this tune for a mere $2,200 when they essentially already sell an increased HP version (SVR) for an added cost of $25,000. Yes, I know people are not paying retail, and that the SVR adds some other changes, but surely JLR would charge a lot more for this, or risk watering down the SVR brand. Something doesn't seem right.

 

Oh come on - do it now while the offer is on the table stop whining about the traction.

Pretend you drive an upscale 2-seat Hellcat Challenger - traction is optional.

Really, seriously, do it. I mean 600hp AND warranty - bragging rights of more HP than an SVR!! Just don't mash the throttle, put 305 PSS on back, whatever.

Your hesitation is inexcusable lol. I mean ====== warranty. Transferable? That would be a complete recoup when it is Huracan season.

Orlando Jag sounds like the kind of dealer I can actually like - I mean I'd stop using the *******-Ship term 100%. Monte Shelton here in Portland? Bunch of conservative old ladies that act like the F-type was a big mistake and 'too loud'. (Funny that s_tealership is a banned word - is this forum owned by a dealer???? .

 

absolutely.

This whole hp rating had me confused. 495hp or 510ps for V8S. I've also seen 503ps. So I looked at Wiki and found that 1 hp = 745.7W and 1 ps = 735.5W. 495hp = 369,121.5W and 510ps = 375,105W. 375,105/745.7 = 503hp. Coincidence?

Conversely if 503ps is accurate, then doing some times's and gozinto's reveals that 503ps = 496hp.

For R's 550hp = 557.6ps.

At any rate 600 - 495 = 105hp gain = $21/hp. A bargain that if it were in the Peoples Republik I would jump on.

 

I believe there was also a 488 PS (or was it HP?) number for the V8S. I got so confused I bought a V6S.

 

Don't feel bad, it's almost as though they were trying to be confusing.

The F type V8S has been described as 488hp, 495hp or 495PS. Now, they are all identical and since, as you've discovered 1PS = .9862 hp ....this is why 495PS = 488hp. soooooo the F type V8S must really be 488hp.....but then JLR North America insists that the rating is 495 hp.

The reality is that the V8S is actually (according to JLR employees in the know) using software marked "510PS" that is used for other platforms. 510PS = 503hp and this is what I believe the V8S really is rated (stock, of course).

JLR N.A. also insists that the V8R sold in Canada and the states is 550hp, however it runs identical software as the ones sold overseas, so the R's are actually 542hp (assuming the 550PS is accurate of course).....seems there are lots of opinions suggesting that JLR's ratings are a bit pessimistic and that also supports the rationale for them keeping the same numbers here despite the switch to horsepower from PS.

The reality of the ratings IMO is;

- V8S = 503hp

- V8R = 542hp

- SVR = 567hp

.....all due to programming.

Clear as mud, right?

Cheers,

Get "and warranty" in writing, because it isn't dealership but JLR that ultimately pays for warranty clauses, and they WILL take a dim view of any mods.

 

If the dealership is marketing this ob their own, they may well be assuming the warranty liability as well. As SinF suggests, see the warranty in writing before you commit to see what you are really getting.

 

dragonfire6,
I would be wary of the warranty, as others have stated, I doubt it's a Jaguar warranty as opposed to some kind of dealer or aftermarket warranty. That said, I have done the pulley/tune to my XKR to about 600hp (same engine as yours). I believe Eurocharged (which is who I used for mine) has offered a special at $799 for both. You do have to install the pulley but even with paying for installation, you're still under $1000, not $2200. I would want to see the details on the warranty.

 

This conversation took place in front of quite a few people and the service manager is supposedly taking me for a ride in his 600hp F-Type tomorrow when I pick up my car. I'll ask for more details regarding the tune, pulley and warranty. As I said, it isn't something I would do right now but if everything checks out and 495-ish hp starts to feel boring, I would seriously consider it.

Any specific questions anyone would like me to ask?

 

I would ask - is this upgrade officially sanctioned by Jaguar and does it affect the manufacturers warranty.

Does seem odd Jaguar would officially approve an after market tune and pulley from a North American tuning shop that has no affiliation to them and hasn't gone through factory testing - that gives more power than their flagship F Type and also maintain their factory warranty.

 

I'm sorry if this was implied in my OP but the service manager did not specify that the 600hp pulley and tune was VelocityAP's. He brought them up when he talked about the 700hp thing the are prototyping.

 

Agreed. Ask for a written copy of the "warranty," and read the fine print. It won't be a JLR warranty.

 

Maybe you should offer to help them fish their monacles out of their champagne?

 

The factory power ratings are at best an estimate, at worst outright lies.

Yes it's true that the vbf file for the V8S PCM has "510PS" noted in the header. I never understood how you can have the same torque but different horsepower from one engine, it's safe to say the 495PS of the V8S is a fib.

JLR North America has been fiddling with the numbers for years, they take the rated PS figure and call it HP. You look at the UK/EU literature and the numbers are in PS, the USA/CAN literature has the same number as HP.

Another anomaly is the Project 7 and SVR, the P7 was supposedly 575PS and 680Nm, the SVR being 575PS and 700Nm. One or more of those numbers is not true, if the R is 550PS and 680Nm... but I also have my doubts if that is true as well...

The later 8-speed Bosch-PCM cars seem to make a bit more power stock than the earlier 6-speed Denso-PCM ones... speaking about the 5.0L only here...
