Yup. That's why we have the cars ourselves. It's why we R&D so extensively. It's why we're the only company with proper datalogging capabilities. So we can truly innovate & push boundaries in this space.

We've partnered with Jokerz Performance to bring you some comprehensive porting & tuning packages for the 3.0L Engines. Our initial research from bolting on one of their CNC ports showed some moderate gains, but with additional tuning & development work on the dyno and the street we unlocked a ton more.

558BHP on Pump Fuel. 598BHP on E85. And 612BHP with our carbon intake & V8 MAF upgrade. We'll be demonstrating this performance in the real world soon. Dyno graphs are all on the website to review.

I might need to acquire a sportbrake for testing purposes

 

Truly impressive and thanks for always pushing the envelope!

 

That's very impressive. Thank you for developing this.

With increased power levels, what do you see as the eventual mechanical weak link in the AJ126 drivetrain? Internal engine parts? Transmission? Differential? I have your lower crank pully and tune in my '16 F-Type, and I think I'm pretty close to the torque limit for the 6-spd manual transmission. I also have a Quaife ATB differential.

 

I am wondering if those of us with the Stage 3 tune can benefit from the addl tuning without the supercharger porting?

 

I want it. Pricing shows $800 for SC rebuild and $1400 for porting service. I'd need both? No other supporting mods required - fueling, engine internals?

 

Any plans on innovating and pushing the envelope into true flex fuel tunes? I don't want to sit at the pump with a hydrometer to figure out which flash I need to load every time I fill up.

 

Very nice! Going to be doing this when I pull the SC for a full cooling system rebuild. Stage 2 to 3 and porting. Like @waldo I have a MT but don't hard launch much these days, but enjoy having the power on demand while rolling.

 

Welp.

The Stage 3 475/470 tune hasn't destroyed my supposedly fragile clutch/flywheel just yet.

So I guess I'd better get the 558 tune and keep trying eh?? 🤪

 

Velocity AP is a class act. Top drawer. I've seen them and their posts on other car forums too. They have products/services that car enthusiasts really enjoy and their performance tunes are tops as well.

Poorly designed and managed tunes can really cause issues. Velocity AP is not one of these.

 

Hi, are there porting + tuning options in the works for the 5.0?

Also where did you guys end up with the coilover system discussed a while back?

 

I'm in the same boat and as I recall, we're *very* close to the rated torque limit for the transmission. I expect the bearings may not quite have the same service life as with stock power and torque

[ please stand by for verification ...]

I thought we were nominally 435 lb-ft with a 450 lb-feet rating on the gearbox, but a check just now shows 440 lb-ft on the VAP site and Wikipedia listing 370 lb-ft as the rated capacity of the S6-45. Oh, well. It's been quite a while since anyone accused me of being sensible.

 

Shut up and take my money.
Any concerns with the zf? As I recall it was rated way above this.

 

The additional edits we developed won't make any difference on their own, better way to think of it is that they are required to allow the porting to be fully unlocked.

 

So, outside of the RWD XE which I know has the HP45, almost all the V6 JLR product has the same HP70 that the V8 has (because the V6 basically is a V8 block, everything is developed around the same drivetrain.) We are running 750BHP through the HP70 without seeing failure yet.

If you have a V6 FType non-manual, you're still well, well within what we consider to be a reasonably safe limit for the transmission.

 

It's not something we are working on at this time. We do recommend the Fuel-IT app & module, with a DSX GM press fit adapter. This allows you to monitor your E85 content in real time.

 

I can give you guys a call of course (plan to) but for the benefit of others, Stuart do you plan to answer my questions? Thanks in advance

 

Realtime monitoring is better than a hydrometer, but if it's winter and the pumps are all ~E50 and you rock up with a few gallons of 93 still in the tank what flash are you supposed to use? Jag made flex fuel cars on the AJ platform no? Seems to me that would indicate the ecu natively supports flex scaling based on ethanol content, or did jag change the ECU hardware to support those models?

 

If you find yourself in a situation where you cannot get E85, or are forced to blend it to a lower concentration, I would recommend flashing the pump fuel calibration back to the vehicle.

 

Good to know, but it'd still be cooler if the car did it by itself 😉
