I have not discussed at any point or attempted the idea of calculating bhp for any of the mods. Torque at the wheel is what matters, is what the dyno charts provide, and is what I use.

We know the SAE ratings for bhp for the stock engines. Pentastar is 285 bhp. JeepLabs stock dyno shows 190 whp. That's a 33% loss from bhp to whp. If the SAE rating is not a solid enough baseline bhp for you, then that's not my problem.

Again, all this talk of drivetrain loss was just to get an estimation of torque at the wheels for the 6.4 Hemi Wrangler in the absence of a dyno chart for this vehicle, to get some better estimations of how it performs compared to the superchargers rather than pure speculation based on hunches. Take it for what it is, ignore it if you think it's garbage, I really don't care. I hope we can get a dyno chart soon so I can update my model of the 6.4 Hemi Wrangler with actual measured torque at the wheels.
