Re: How much power you think the 3.6L pentatstar is capable of?

Well, I was debating whether or not to supercharge my V6, and it looks like I will based on how Ajag said his transmission was holding up (at least with stage 1). What boost does it run 8lbs?

Yeah man....stage 1 pushes between 7-8 lbs of boost...Stock you're probably pushing 185-195 AWD HP to the wheels...stage 1 will get you to an easy 300-330HP to the Wheels..See attached pic for 0-60 validation

I really only tested the 0-60 a few times but the best I got was 0-60 in 4.6 secs on stage 1 (330WHP)

Just as an FYI- I ran my Jeep for 12K miles on stage 1..Initially I beat the living shi* out of my jeep..no tranny issues at all.....I have 2K miles on Stage 2 and am pushing over 400Hp to the wheels...I have hammered on it a bit since stage 2 and now pushing 14LBS of boost it absolutely FLIES...

I beat it up pretty good yesterday to really test out stage 2 and it's just amazing to me how much faster this Jeep is now ...acceleration through 120-130MPH is just draw dropping when pushing 14LBs

the ONLY difference between Stage 1 and 2 is larger injectors and larger piping in and out of the intercooler...and a much larger intercooler.

I still have my Stage 1 Kit ...but since stage 2 is not readily available I had to buy the whole kit...not just the upgrade parts.

Damn really making me want to void my warranty for this haha. Did you need to go with an exhaust as well or is the SC set up fine with the stock exhaust system?

the tune you get is designed to run with the stock exhaust and factory air box...so it's actually pretty quiet and very much a sleeper. Adding an exhaust doesn't really affect the tune or output much ...so you can choose to do it or not do it ...

I chose to go with a Gibson cat back Exhaust ....then I went with a front muffler delete with the Gibson...but it got pretty loud and droney on the highway...so I have since replaced the Gibson with a custom Magnaflow muffler setup with the front delete/xpipe and its much more bearable...no drone. I know someone who ran the RIPP kit on his factory exhaust and had no issues at all...he was pushing well over 365Hp to the wheels with the stock exhaust...running 9lbs and then upgraded to stage 2 and was pushing over 406AWD HP ...with the factory exhaust ..so its def not a limiter

stage 2 also uses a K&N filter instead of the factory air box so its MUCH louder as far as supercharger blowoff sound..

Re: How much power you think the 3.6L pentatstar is capable of?

well....I have had some time to mess around with my Stage 2 RIPP kit and I can report that I am starting to REALLY see the limitations of the 3.6L engine ...without any mods to the lower end...


When I started with the stage 1 I was reliably putting 330HP down to the wheels...then I upgraded to this Stage 2 Kit running 9 lbs of boost and was putting down 403AWD Hp ...I decided to see how far I could take it and it's been a nightmare ever since

Even though everyone was recommending that I leave things alone and stay at 9lbs..I decided to up the boost to 13LBS ...


It ran good for a very short amount of time...I started to develop issues ...I started seeing a lot of knock that we could never seem to dial out...and then I had some AF issues with it going lean...so I installed an SRT fuel pump along with a JMS Powermax fuel pump voltage booster setup

no more fuel delivery issues....then the problem migrated to the valve cover gaskets...the added boost blew though the gaskets and my Jeep is now blowing lots of oil through the Exhaust ...which in turn is throwing PO420(Cat errors) as well as blowing oil out the tailpipes.

needless to say this is probably part of the misfire/knock issues I'm having.

So I have no choice but to start dialing this thing back...unless I rebuild the lower end..which isn't worth it on a V6

I'm just hoping that I can get back to the 400HP mark without this thing detonating for good...but I am thinking realistically these 3.6L's are probably really only good for ~350ish HP to the Wheels before things start to really get complicated

I've spent so much time and money on this thing at this point and it's just not reliable that I hate to rip everything off ...but I am quickly getting to the point where I may just do that.

I really regret not just getting the SRT from the start

for those worried about voiding the warranty...don't supercharge your jeep then

I never worried about that and my dealership didn't either...they still take care of anything I need without giving me crap about the Supercharger

From someone who used to own a performance shop and regularly push our own personal cars to the absolute brink of death, so that we could give our customers 99% power and 100% reliability....id say that your above statement is harsh.

Tuning is always paramount. We went out of our way to use the best tuner on the west coast exclusively, after he easily worked through major issues our (in our minds) fantastic tuner couldnt. He also increased the power of all of our cars across the board, at more reliable settings.

Also, when it comes to boost via supercharger or turbo...of course there are plenty of things that need to be addressed prior to going big. 6, 7 , 8 lbs, no biggie. but if you want to play with the big boy boost you have to pay attn to those things like fuel, gaskets, etc prior to pushing the envelope. At this point, perhaps you caused other damage (I hope not) with your knock and detonation and now even if you address the other things on board, you may never be able to get back to going to max testing, or even get back to the baseline you had at 9lbs before. Part of the game, unfortunately.

The title to this thread is deceiving too. Are we talking all stock untouched internals with just power adders? Or, can I balance & blueprint the motor, add a boost specific cam, lower compression pistons, head work, etc? If thats the case, the answer is going to be a whole lot different.

Once upon a time we thought my stock block 5.3 silverado could only handle 600hp. When we had it run up to 1000 we had heads shakin everywhere.

Yeah...I am talking about strictly making power on a 3.6L with power adders...no internal work or rebuild of the lower end.

I tried to address as much of the anticipated issues as I could before upgrading to the stage 2

I ran the Stage 1 for 6-7 months and logged in 12-13K miles reliably...without any real issues.

I upgraded the fuel system before stage 2 thinking that would help...but there were other issues as I stated...and also...no one really seems to make upgrades for these 3.6L engines (at least i couldn't really find any)

This has been one big experiment for me to see how far I could push the stock block/heads and pistons etc...and from what I am seeing I am getting pretty close...I bet you could make a LOT more HP with a 3.6L if you tore into the heads and internals(sleeves etc..) but its just not worth it for me.


I had the dealership run a full diagnostic and engine test for me today...aside from the leaky valve covers the engine is showing no real signs of internal damage or compression loss ...but I am sending out the oil for a more in depth check to see if there are any metal particles etc. in it...under the recommendations of the dealer.

as much detonation and knock as I have exposed this engine to though at this point I don't see how it couldn't possibly be damaged.

Which is also why I am really considering just ripping the blower system off and trading this thing in for an SRT

I have worked with some VERY good tuners on this and even under their supervision and skills with tuning we just have not been able to keep this running perfectly for any length of time ...

Just wanted to share some of my experiences with others here ...by no means am I an expert ..I just write the checks and have the smart people work on this for me

If you're blowing oil out the exhaust it would seem as though you've damaged a piston/piston ring/cylinder head. Not sure how a valve cover gasket blowing out could result in oil entering the combustion chamber.

I'm having the valve covers ripped off next week..the dealership seems to think the oil in the exhaust is the result of the boost blowby

Which I've been dealing with for a while
Even with the catch can a fair amount of oil still seems to make it into the engine under boost

The dealer just tested compression so I'm hoping that means there isn't a damaged piston..but like I said
I'm no expert and know very little about how the internal workings of this engine operate
I wouldn't be surprised though if I did damage this engine


I just spoke with the speed shop that does all my work and they too seem to think its blowby but damage is a very likely factor as well...even though the dealership did a compression test i'm told that may not be indicative of potential piston or ring damage..so they are recommending a compression leak down test?

which apparently requires removal of the upper intake system ...I'm going to have all this stuff checked out next week to get a better idea if there is internal damage...


Oh well....you play you pay right ?

Speaking of pay, how much total have you spent on it to get to where you are at today? just curious what all it takes total to get to that point
