Does this hold true across all the 5.0L models, ie. XFR, XJR, XKR. and LR/RR models as well?

 

For all the 2013-on versions that switched from Denso to Bosch, yes. So yeah, if you want a 650BHP Range Rover sport, crank pulley and a tune will get you there.

 

Depending on how you measure the V8S (488hp/495hp/495ps/510ps) the SVR and P7 have a factory tune that bumps it 65 - 87hp.....with ZERO hardware changes....is it that hard to believe that a decent aftermarket tuner could bump it 30hp more?

It's like the difference between the V6 base and V6S; thier tune puts out 416hp......on a V6S with 380hp that's only a 36hp boost.....but on the 340hp V6 Base, that's a 76hp boost. It's the same with the V8 - VAP's tune is good for 605hp......doesn't matter which V8; on the SVR, that's a 30hp boost, on the R it's a 55hp boost and on the V8S it's a 100hp increase

So what is different in the earlier 2010-2012 engines, and what HP are they capable of with a tune alone?

 

Is the Project 8 tune available and can it be flashed to cars?

 

Yes it is, and yes it can. Our UK Dealers David Appleby Engineering can do it for you. They are running the Invictus Games GT4 FTypes so you can probably check them out while you're there!

 

Good to know, I have an SVR. Out of curiosity what is the difference between:
- Jag SVR & Project 8 tune, is it just power or did SVO change other parts in the tune?
- How does one of your tunes differ from say the Project 8 tune?

I know remapping invalidates warranty and can be detected, but would Jaguar's own Project 8 tune invalidate warranty if the hardware between all the cars is same? Assuming engine cooling potential on SVR and Project 8 are same?

 

Fundamentally it's mostly the tune, although obviously the exact run of the exhaust pipes etc. won't be identical. I think there's not much to choose from really, between the P8 and our tune, you'd fine not much difference.

From Jaguar's point of view, it doesn't matter if you change 1 or 1000 bits of data, they will just consider it 'tuned' and that's it.

 

Very true, I guess the only way warranty would remain intact if Jaguar themselves started offering upgrade or performance packs for customers officially and flashed cars or they partnered with a tuner like yourself.

Both unlikely to happen, which is a shame as what Ford do with Mountune, Roush etc. is great, but I guess if everyone could upgrade their tune from the dealer, then they'd sell less new cars.

 

I believe the claims given to JVIII were whp (not bhp). 600 bhp with tune alone have been documented.

 

It had crossed my mind several times that we could approach JLR, but manufacturers these days are often of the mind that they can do it themselves, in house.

They probably would sell less new and higher spec cars if you could just crank it up with factory tune. But that said, it happens all the time.

Just in the last couple days Aston released a 'dealer-fit' software upgrade for the 2013-2015 DB9, which was essentially a detuned 565 Vanquish so once they are out of the sales cycle for that model sometimes they decide to tune their own models.

 

FWIW, the Project 8 has upgraded engine cooling and intake systems, according to JLR engineers. I suspect the cooling mods enable the engine to maintain peak power after a few hot-laps, rather than contributing power on their own. Not sure about the role of the intake - could be a packaging thing.

10 Things You Need to Know About the Jaguar XE SV Project 8 - Motor Trend

 

Sure but the point is that the engines are all the same; identical from a hardware perspective. From the article: Foster said the Project 8’s engine is essentially the same one you get in the 575-horsepower F-Type SVR. The only significant differences are the engine-cooling and air-intake systems.

....and of course the 575 hp SVR engine is identical to the 550 hp R engine and the 495hp V8S engine - all identical

The air intake change on the P8 may be to help performance or it might just be due to the differences in the cars themselves....not that air intakes have proven out to make much (if any) difference to the power of the supercharged V8

You're probably right that they increased the capacity of the cooling system - I hope so, anyhow.

Don't know how I missed the most recent exchange above, but some clarification to the above:


The OEM upper pulley on the V8 is 66mm. A 62mm upper will result in a 6.5% speed increase and a 60.5mm will result in a 7.3% increase.


The OEM pulley on the V6 is 62mm and a 60.5mm swap results in the 2.5% speed increase. Not worth the time and effort and in combo with the lower pulley, pushes the SC too far into the inefficient region. I can feel the engine running out of steam over 6600 rpm. When I have the opportunity (e.g. snout failure), I'll probably revert back to the 62mm pulley.


When installing that upper pulley, we had to knock down just a few dimples from the casting process to ensure clearance. Since the V8 has a larger SC (TVS R1900 vs TVS R1320), I suspect more rigorous grinding might be required to fit that pulley.

 

Would love to know the answer to this one. What is it about the Denso vs Bosch that holds the earlier platform back? Is it the supercharger actuator (Denso) vs solenoid valve (Bosch)?

 

we pretty reliably make 60WHP on the Denso 5.0SC with an upper pulley & tune. The lower pulley hasn't made more power on those cars, largely due to cooling issues.

The Denso ECU is FAR less adjustable and precise than the Bosch MED17.8.31 & 8.32. Whereas with the Bosch you can go in and make very specific adjustments to values at very specific points, in Denso you can essentially only 'move the whole line up or down.' It's just not as good a processor as the Bosch.

 

Well then...that's a bummer! Would water/meth (cooling) help with a crank pulley.

 

Hi,
got a Fpace SVR 550bhp and I think 680 or 700 NM of torque and looking to increase the hp and the torque on it.
what's my options,
I heard lister pumped it up to 675 BHP and 880NM of torque
I think they removed the cats too.

 

We have a dual pulley setup that has now been installed on thousands of vehicles. Will get you to 660BHP & 630 ft/lbs, with appropriate quality pump fuels:

How do I determine which engine I have? They claim 30% more Hp/Tq - significantly more than 50hp.
