I just want to hear the supercharger noise.

I'm a child inside, I know. :) Noise videos please.

It hasn't been mentioned before, so I will: Don't do it.

I don't believe that there has been a single hassle-free turbo/supercharger installation reported in the JK forums. Everyone goes into it full bore, and then sheepishly return with tales of woe.

And...I'm a forced induction fan; just not on a Wrangler. [except for the turbo-diesel that I'm ordering when the 2021 order banks open]

We have had countless positive experiences with Forced induction here at Doetsch Offroad, including my own personal 3.6 that ran a RIPP unit on it. GOOD Tuner & good gas is a must

I really don’t think the engine/drivetrain can handle the power this puts out. Do we have any testing results other than a couple dyno runs? Any long term testing results would be nice.

I ran 7, 8.5 and 10 PSI through my identical 3.6 Pentastar in my 2016 Grand Cherokee. At peak, I made 417awhp & 396tq.

I put 30k miles on that SC with no major issues to speak of until the new owner blew it up on garbage gas, climbing the AZ mountains in the summer. He has since rebuilt, lower comp and runs 12psi on pump gas reliably.

I'd run the smallest pulley and vent at 7PSI to build boost as fast as possible and leave headroom for safety..just want the low end torque. I'm looking forward to seeing some feedback on real world usage traveling through changing altitudes and octane availability.

Your 10.2:1 compression GC 3.6 is identical to the 11.3:1 compression ratio JL 3.6?

PD superchargers build boost down low, doesn't make any sense.

It does make sense, I want peak PSI at the lowest RPMs as possible. Since superchargers run off the crank speed, reaching the peak PSI very early on mens the supercharger will surpass that peak with increased engine speed. Like you mentioned, these build up quickly at low RPMs and that's what i want to maximize.

The moment the bypass valve closes you have boost on a tvs. Even if you made it work you'd probably lose hp spinning the supercharger faster then it needs tho be spun and have more problems with the belt.

I know, I'm not worried about losing HP, just want gobs of torque under the curve starting real early. A heavy-duty belt setup would take care of reliability. It would be a small price to pay for a significant increase in torque where it matters most and cheaper than a V8 swap.
