hemi upgrades

I've been reading around the forum and haven't found much .. Has anyone upgraded there hemi? Besides cold air and exhaust .. I've been looking at injectors throttle bodies etc.. Is love to see some builds and upgrades .. Right now I've been looking at changing the basics injectors throttle body thermostat but I came across a vortech kit for the charger that I'm almost positive will work .. And I'm curious as to anyone else who has went this route without custom tuning and what has been done

I'm going to do a ultra cheap homemade intake and probably a cat back exhaust and have been kicking the thought around about some big coils but that's about it for my Commander but I would be interested in reading about what others have done if they contribute to this thread.

Most of what I have heard and read about on this forum for upgrading any Commander (Hemi-powered or otherwise) revolves around cold air intakes, exhaust upgrades and tuners/programmers to program a performance tune into the engines computer. Once in a blue moon I hear of someone attempting a full intake swap with a 6.1L SRT Hemi intake - but they are few and far between.

There are even a couple of brave souls who have done full blown engine swaps - but it's a lengthy and very costly process.

You can upgrade your Hemi - it all really boils down to 2 things;

What is the main purpose/driving application you have in mind for your Commander...........AND;

How much money are you really willing to spend?

Most people don't go beyond cold-air intakes, cat-back exhausts and programmers - because it just becomes too expensive once you go beyond that.

But if you have the budget - anything is possible.

Yes ice noticed the same few upgrades as well .. I've found several vortech kits pretty cheap made for the charger .. But from what I'm looking at It should have 0 issue bolting up to the commander.. I was just curious if anyone has used any thing similar or went a little further then the exhaust cold air etc..

This is the first I've heard about these Vortech Kits and anybody considering trying to bolt them up on a Commander;

Maybe you can be the Guinea Pig Timmy.

Let me re-phrase because I don't think what I was trying to say came out right;

I am very familiar with Vortech Superchargers;

I have never heard of anybody talking about putting one on a Commander until now;

And like I said, you can be the guinea pig and be the first one on the forum to try it.

Well I have found a couple under the 3 grand mark so if nothing unforseen happens between now and tax return I just may .. For now I'm just focusing mainly on getting the wheels swapped .. Lights changed my exhaust and a few other small things

Honestly, I think you're better off building the internals first before throwing on a supercharger. Right now there isn't much more to be had from a stock Hemi, and they're not really built to take much boost. I've read that going over 8 psi tends to start breaking things. I've also heard that it's difficult to fit a supercharger on Jeep Hemis, but that could be a lie seeing as they seem to fit them on LX Hemis.

The most restrictive components of the Hemi, as far as I know, are the headers. They're extremely restrictive, which is why there aren't many gains to be had from a CAI and catback exhaust to begin with. I know people have been working on fitting headers from SRT Jeeps into their systems, and the increased airflow along with a proper tune could net you some nice gains.

You could also look at a cam swap. The cam in the Hemi now is a nice smooth cam, but doesn't make great power. You have some options for bigger cams, either Mopar or aftermarket. The cam out of an SRT Hemi will fit and net you a little power, but there are plenty of other options out there. If you're looking for a serious beast, you could step all the way up to a Comp 273.

As far as bolt ons go, the only place you'll see some gains is with a CAI. Most of them are controversial as far as power gains, but two I've heard consistent good things about are the AFE and Volant intakes. The exhaust is already overly restrictive because of the headers, so you won't see much gain from an aftermarket catback.

If you want some more throttle response, and possibly some mileage or horsepower gains, you can port and polish your throttle body. There's plenty of metal to work with, and you can easily get to an 84mm opening. I made a thread following my personal approach to porting and polishing, and really it's a pretty straightforward job.

I've looked at exhaust and the vortech kit with the the elderbrock direct for super intake and for now that looks like the best bet
