Also found this chart posted on this forum too. Shows that at 2000 rpm the 2.0 is making 40-50 more ft-pounds than the 3.6. The TQ cross over happens around 1500rpm when the boost starts building.Bull shit. Well into boost by 1900rpm? Nope. The 3.6L makes more torque than the 2.0t until about 2200rpm because it's not into boost yet. And who cares if they are both gutless below 2300 rpm? You don't want/ need to be at peak torque or boost when cruising around at low loads which is the whole point of having 2 overdrives. Some people act like the thing takes more than a fraction of a second to downshift and get into the power/ boost.
The dyno chart doesn't lie, neither engine makes shit for power below 2k rpms. The 2.0t makes less than the 3.6L below 2200 rpm period. But hammer the throttle on either and you're well beyond that nearly instantly. The 3.6L needs to get to 4k plus for peak torque and 6k plus for peak horsepower which is the diffrence you're feeling. Below 2200 rpm both are gutless. Beyond that and into the boost the 2.0t comes and strong and fast. The 3.6Ls torque output just remains gutless and no amount of gearing is going to fix that. Unless of course you cruise around at 4k+ rpms, but that's dumb.
What the hell are you talking about? You didnt specify manual transmissions at first and the JK and JLs are still geared differently even with the manuals. Do you know what you are even talking about? Any change, no matter how small, will change the impact of a regear.
It does if you find one that starts the run off the throttle above idle. Especially with a turbo.
So you didn't look at the chart I posted?
Any chart that smooth isn't a real dyno chart period. The perfectly flat m235 line is even more comical. I'll stick with legitimate dyno charts from reputable sources. Go ahead and put a boost gauge on the 2.0t and see for yourself if it's well into boost below 2k rpms. It's not and I know that for a fact as our 2019 had a gauge on it.
To get the most accurate dyno run you should be in 6th gear (1-1) I'm pretty sure you can't even get it to manually shift into 6th at idle?

Not like you could back in the day.
Im sure.
I’ve got 3.45 gears in my 3.6 JL, spinning 35s…hardly ever see 8th gear…only downhill on a highway! Most shops recommend 4.56 gears for 35s…4.88 for 37s. Just what I’ve been told by several shops.
There isn't much difference in rpm in top gear from a 33 and 4.10 to a 37 with 4.56
I have a gladiator on 35's with 3.73 it sees 8th on flat ground and gets an average 19mpg, it's also just fine offroad, now im not pounding it on a vertical rock face but it's climbed 38degrees without much trouble. I think it would be perfect with 4.10. We also have a jlu xr with 4.56 on 37's and it's fantastic, I wouldn't even consider changing them. Also have a 2 door jl on 33's with stock 3.45's motor is a 2.0 turbo. It climbs grades in 8th. Sometimes I just dont understand where some think that jlu needs 5.13's on 37's.
