Decided to supercharge over a swappina to a Hemi

[JeepOfTheseus]

Get it tuned and tuned properly. One of these days, I wouldn't mind going back (assuming V8 never gets CARB'd and superchargers do)...but if I did, I would want it to be very conservative and light on boost, because these engines don't like it.

i would start poking around in other forums like chargers and challengers and see how common 3.6 SC is over there for a platform that is traditionally been paired with power mods.

If i recall the 3.6 needs serious internal improvements to best handle forced induction. aka forged pistons, better rods, a valve train not made of cheese.....

If you were always needing 7th gear @ what... 2100rpms?, whereas with the SC the added torque might mean you'll use 8th at 1700rpm, that could be where they are seeing the mpg savings.



Thats 1-2 psi at cruising speed. It's probably 6-8 pulley so it'll be more when called upon.

That makes more sense. I love forced induction as an enthusiast but I dont love the idea of using the 3.6 for forced induction. Id happily wait for a 5.7 swap and know everything was good and warrantied for a year.

1-2 pounds of boost is not worth the investment it will cost and I seriously doubt it will make much of a difference. Ive been out of the forced induction world for decades but kits in the late 90's started at 8psi and went up. I think you're making a horrible mistake and I know you dont care but Iam just putting it out there.

Needed to put it out there...Why?

Not a mistake if it satisfies me.

1-2 pounds of boost makes a substantial difference, especially when that is all that is needed to keep the thing from downshifting too much.

I owned a shop back in the 80s-90s. We installed quite a few Procharger and Vortech kits. Most topped out around 8-10 psi. Now, if you happen to be thinking of early turbocharged cars like the Buick GN (I owned two), then, yes, we would push over 20 psi routinely.

^^^ That is a popular misconception. The 3.6 was actually designed to be a forced induction motor, according to what I have discovered. Talking to the Ripp folks, they said this system is entirely safe at the delivered boost levels up to 8ish PSI, which is around half an atmosphere. People got into trouble by pushing it over 10 psi and running it hard all the time. We discussed the need for a forged short block, which I am willing to install, but the Ripp people say it is money wasted to do so, unless I decide to go crazy...

I had a procharger on my 95 mustang. P1SC and I ran a 12 pound pulley that was the max for that SC. The D1 could do 16-18 lbs if I remember right.

Yea, I think you're in over your head but I wish you the best of luck.

Can't disagree with wanting a 5.7. With ya all the way.
But
I own a 3.6 and an AEV Gladiator at that.
Translation: Way too much money invested to swap vehicles, I'm stuck!!! ;-)

Any links, or just from chatting with folks? I'm genuinely curious, because I've been under that misconception as well from multiple posts/claims.

These were indeed engineered for eventual boost. Part of the design for the upgrade process back in 2015 was for this reason.
You'll appreciate the torque in the hills/mountains. My wife's JLU stayed in 8th gear in many mountain passes while on those same highways, my JT was downshifting and upshifting constantly.
Frankly, I think you are heading in an interesting path and I'll be watching. Heck, these same engines run a different tune and have better output when put in non-Gladiators, so...........

...Derived from my conversations with users, manufacturers, and others.

You know, you are partially responsible for this decision ;-)
You have held your ground and stood behind the 3.6 as a viable and good motor. I thought about it, considering your considerable experience, and concluded you were on to something. I suppose you opened my eyes to the possibility of just addressing the power concern by looking deeper into the 3.6.

Of course there's a such thing as too much, going crazy and stupid with it, but you don't have to max the thing out to realize more power

 

[Jteakus]

What is used to adjust fuel and timing?
Edit: I see they are using HP Tuners to upload their tune with a dyno tune recommended.

 

[ChrisNLA]

What is used to adjust fuel and timing?

HP Tuners, most likely. Then just set all the tables so the engine doesn't kill itself.

Good luck on your project and no shade from me even though I'm a N.A. gasoline motor type, that wants more of a tractor motor... Not fast but runs forever.
