Wow.. that's pretty good 40+ hp...

 

Its not terrible .. a little i4 with a turbo putting out numbers that are close to their V6 option as far as I recall 👍🏼

 

Agreed: not shabby. That’s 165hp/l vs 150hp/l on a fully tuned V6.

 

I guess I misread the screen when I first looked at it... more like 20+ hp (260 to 282)... still not too bad!

 

Hello All, a recent P300 owner as well. I'm curious, why did the shop state the engine was at it's "limit" with only a tune? Is there something we need to be aware of with these Ingenium motors?

+20whp and +40whp shouldn't be enough to push anything to the edge.

 

Shop owner said he owns a Ford with the same engine .. I wasnt going to argue with the guy , but upon asking if more power can be gained , he said I'd run the risk of possibly blowing a piston 🤷🏻‍♂️ Its a lease , so I am not looking for any trouble with Jaguar.

 

Interesting, I thought the Ingenium engines weren't Ecoboost based. And I agree on avoiding issues with the lease. Is there an Ingenium 4-cyl with a higher state of tune from the factory than this unit?

I wish there was a way to see what changes in acceleration the tune made in somethink like a 1/4mi or 60-130 time.

 

I've seen Jags with a P340 badge.. Not sure if thats still an inline 4 or if its the 6 cylinder.

Otherwise another thought was that all the "plug in tunes" you see online, offer about the same results as the shop was able to obtain.

I'd take a guess & say thats probably the safest tune for the engine .. anything higher probably causes issues?

 

P340 (and P380) is a V6, 4-pot are P300.

 

I looked at the engine bay, and I am not sure where/how the intake path can be improved for more noise.

Oh well!

 

Hey, do you have a different image of the dyno plot, or an overlay of stock vs tuned? I'm curious to see where the power starts to fall off. I assume it's around 5500-6000, but what's happening at the upper rpms?

 

+1 on not being the Ford engine.

 

To add a little on-road feedback, I've gotten into the throttle a bit more, and it seems like there's some level of tq management in certain situations in 2nd gear. I need to test to see if it's tied to Traction Control being on, but it's interesting. The car feels stronger in 3rd and 4th vs. 2nd, and it should not feel that way.

Also, I had a few opportunities to do some roll-on testing with a colleague's factory stock 2011 BMW 335i X-Drive, and even with my P300 being very fresh I was able to stay within 1-2 car lengths up to very healthy speeds. No question his turbo 6 is stronger at up top, but it makes me feel the instrumented test numbers published by Car and Driver are a bit conservative for the 4-cylinders. I'll need to log some Dragy numbers for the F-Type once a few more miles are on the clock.

The car seems to be held back by the factory programming, albeit, the transmission feels great. Any feedback on shift speed using the paddles vs. leaving it in Drive or Sport?

 

Curious about your thoughts.

i was disappointed in my cars 0-60 feel.

discovered the launch control. Traction off. Rev matching off.

much better.

that car and driver review was weird. I think the car had the optional bigger wheels and tires to slow it down. Also the heavier bigger brakes. Two good ways to slow the 0-60 down. Then too, they never mentioned the Launch control. It makes a big difference

 

I haven't tried the traction control yet. That's a great idea! My car has the bigger wheels too, and it does handle well, but they don't help with greater rotational mass to move around.

I wasn't aware there was rev matching on the auto. How do I turn that off?

I have a Dragy, and I can try and get some data on the right day. It would be interesting to see what the car runs.

 

Hoping you can figure out to turn rev matching off maybe!

I know it is off in launch control. The car seems quicker. Chirps tires.

know little about turning traction control off. The car gets squirrely.

 

I went out and got some data. Thank you for the heads up on the launch control. I was able to use it and it did bark the tires on the 1-2 shift. I had traction and DSC completely off (hold down the traction button for 5+ seconds).

I'm going to make a thread about my results, but I was able to get 13.85@101.93 and 13.88@102.26 in 13xx to 15xx Density Altitude. At sea level, or corrected, the car would be a bit quicker, but I'm quite surprised at the performance with less than 700 miles on the clock. I think this validates that the C&D test car was compromised in some way, especially since the 296hp XE went 14.2@99 in their review and it's likely 400-500lbs heavier than our cars.

I have a '20 P300 convertible with the 19s and a few options that would add a little weight, but nothing crazy. I think a true stripper coupe would definitely pick up another .1-.2 and maybe 1-2mph.

 

4pot with mods P7 grille,lowered on Eibachs springs,H&R 15mm spacers all round, Conti Sportcontact 6 tyres, 305/30/20 rears 265/35/20 fronts, straight through exhaust ,twin 4.5" tail pipes, Maxton design rear lip spoiler and rear diffuser splitter extensions, color coded red striping, color coded badges.

 

Powerhouse - that looks awesome.

On the bigger wheels, I looked at the question of weight at one stage and really there wasnt a lot of difference because the bigger the wheel, the less rubber sidewall and the more clear space between spokes. I dont think you'd find a lot of weight difference between an 18 inch wheel and tyre, and a 20 inch wheel and tyre.

Forged wheels however make a very noticeable difference on the v6 at least, apparently also on the 4 potter XE (my XE friends tell me), I would think you would potentially get some improvement with them.

 

Thanks Bruce, the 2.0 is what it is and has plenty of power for me, it’s grand for day to day, would never bother with tuning, have done my power trip on past cars such as my xkr, the straight through exhaust gives a great noise for a 4 pot and for the look it’s stunning, no more mods for me
