'18 JLR 2.0
I've was wondering how all the aftermarket baseline dyno curves compare to each other, and found a neat website that lets you convert images into CSV data www.graphreader.com. So with some work, I've collected some baseline 2.0 dyno charts and plotted them out together.

Some observations:
  • automobile-catalog.com provides engine torque that has been estimated by a computer. I'm not sure how they do this, but I found that factoring 85% for drivetrain losses puts it pretty close when ignoring below 2500 RPM.
  • Some plots don't look accurate below certain RPMs, and should probably be ignored (ExtremeTerrain.com's 3000 RPM, Superchips below 2200 RPM)
  • Vaitrix & Eurocompulsion are sharing data
  • not all dynos measure power equally

Sources:

Update: I've put together what I think is a good average of all these dynos. Looks like peak torque is around 275 lb-ft from 2750-4100. If this is true, it means that there is either 9% drivetrain loss (which I highly doubt), or the 2.0 actually makes more than the official 295 lb-ft at the crank. Even the lowest peak number (Mishimoto @ 265 lb-ft) is only around 10% less than the official published torque number.

Here's what I did to get this average:
  • Ignored the computer generated data from automobile-catalog.com
  • Ignored the unrealistically steep sections at the beginning & ends of some of the pulls (ExtremeTerrain.com's & Superchips)
  • Smoothed out minor bumps & dips from where certain data starts & stops

Below is the data for my estimated average. It was originally broken down in 10 RPM increments, but I've found it's much easier to deal with 100 RPM increments and still accurate enough.

I enjoy seeing this kind of data. Thanks for the effort!

What about with etorque?
eTorque is lower in the RPM range (up to 1500 RPM I believe), and only applies in 1st gear starting scenarios. I've tried including it before, but there is simply not enough information available to do it accurately for it's limited benefits.

I'll definitely be interested in the 4XE dynos though...

...and the resulting wheel HP curve using the estimated/averaged torque.

Awesome data!
I saw you had this data for the 3.6L as well. Would be cool to see them both in the same graph.
I used to have a 2016 JKU 6spd and I did the chip, exhaust, air filter updates. It was fun to drive but no where near as much power and torque as the 2.0 turbo stock. The turbo is a lot more fun to drive. I love the fact that the torque peak is low and you feel the dramatic ramps up. The turbo puts the power and torque where you drive 99% of the time. I was always disappointed with the torque of the 3.6L, even with the manual trans and upgrades. I like the idea of the gladiator, but could never consider it with the 3.6 engine and the smelly diesel is a downer as well.

I’m sure a 392 is inevitable.

I'd rather not post a comparison chart here, as any discussion involving 2.0 vs 3.6 never ends well. Even though I tried to be as accurate and open about my methods as possible, as soon as I show a comparison graph people assume I'm bad-mouthing their choice of engine. That doesn't mean that I haven't compared the two myself though, just that I'm going to refrain from making direct comparisons on this forum. You're more than welcome to use my data to compile your own comparison chart (the raw data can be found here).

I can't wait for those dynos... Also the 4XE should be pretty interesting.

Totally agree in the “versus” saga. It will never end. As long as folks are happy with what they got, then that is all that matters.
I am excited to see the 4xe data. All that electrical torque is very enticing. I also like the idea of going electric as the range is all I would need each day if and whenever we go back to office.
At said, the V8 sound is priceless and I hope FCA prices it right and doesn’t overdo it. It is interesting to see that the Jeep Cherokee SRT vs Durango SRT have like $10k difference in price. The Durango has a 3rd row and physically more material. I really think getting a Jeep V8 would be a long term keeper.

Can we order the 3.0diesel or 392 or 2.04xe in a 2 door JLR. If not which engine is the best option for light weight 2 doors?

No, the 2-door isn't available with the 3.0, 392, or 4xe. The only 2-door engine options in the United States are the 2.0 & 3.6. The 2.0 has only ever been offered with the automatic transmission. The 2.0 (and 3.6?) has been offered with and without eTorque depending on year/trim level.

You will get many different answers on what the "best" option is. I recommend taking a few test drives.
