7th Gen ('06-'07): Supercharger anyone?
#2
I've read that a supercharger won't fit under the hood. I hope it's not true, because I worked for Ford for a year and a half, and based on that experience, I would never own a turbocharged vehicle. Superchargers are basically three parts and never give anyone problems that I'm aware of. Turbos are piles of parts designed to enrich dealer service departments, and while in theory are preferred by manufacturers because they don't hurt mpg, in practice, they suck gas more than any supercharger.

Easiest way to make it work would be similar to the old 3800 centrifugal kits - mount the blower above / in front of the trans and run a jack shafts to their belt system. Still going to be clearance problems, but there's a lot less to deal with over there. Would also still be a custom job and way more expensive than a turbo kit.
If you don't care what kind of supercharger, a positive displacement one would be easier. They've got bolt in setups for the LS, you'd just have to figure out the belt system and what you'd do about the hood clearance. At least that would be centered over the engine, so a scoop or cowl would look less goofy.

As for them being installed to bring in dealer service, again that's not relevant here. The choices are either an aftermarket turbo kit or a custom one off blower kit. Either is going to far higher than OEM failure rates, and it's not like a dealer would service it.
Like them or not, they'll make the most power and in this case, a turbo is the only drop in option for boost.

Turbochargers definitely have better fuel economy than superchargers, especially positive displacement blowers. That's why most of the automotive industry has turned to them to meet CAFE regulations. To be honest, that's not particularly important here though either way. We're talking about a 500+ crank hp V8 in a relatively heavy car with an old 4 speed auto. This certainly isn't being done for gas mileage.

Read the comments, especially the one by F1500, which addresses the mpg. (Most of the others are reliability complaints.) While of course any lead-footed application of forced aspiration is going to reduce mpg, it makes no sense to waste more gas than you have to, especially since gas will hit $4 again eventually. And lies offend me. EcoBoost is a lie, one effectively addressed by F1500.

Obviously not. I was just mentioning the true reason why the industry went turbo rather than blower.

And this is the typical Ford response to the reliability issues: pretend it's not a common concern when it is. The CRC is where I worked.

Regardless, I think it's rather irrelevant to this topic. If the OP is concerned at all with gas mileage on a build like this then he's doing it wrong.
To start, if you were concerned about gas price, you wouldn't buy the biggest engine in the lineup that is reccomended to be run on premium (nor would you buy this platform if it was a main concern). Secondly, you wouldn't be looking to spend $10k on a supercharger (or turbo) + built trans to make it reliable. That's more than 75k miles worth of gas.

We looked at other options from other manufacturers with NA 4 cylinders and there was not enough power. We looked at NA v6 options including the Edge, and although the power was just as good or even a little better, the fuel economy isn't as good for the type of driving we do (mainly highway). We have friends with a nearly identical Edge that got the NA v6 option and have a very similar commute to us, and they get notably less mileage than we do.
I'll admit, I would've preferred the TT V6 if it were me so the engine had a bit more power out of boost, but it does just fine for what she wanted.
It's not like EcoBoost is anything particularly special either. A lot of manufacturers are moving to smaller turbo engines, they just don't all have a catch phrase to describe it.

Guys, the comparisons of various ways to setup a boosted drive train is a great discussion topic, but let's try to keep this on track for the OP. Frank Jackson is looking to know more about options to boost a LS4.
Thanks!
Thanks!

In short, there are zero bolt on options to supercharge the LS4, especially that'll fit within the confines of the stock engine bay.
His only real option here (assuming he doesn't have the engineering and fab skills / tools) is to take it to the nearest fab shop with a giant stack of money. That last part is always going to be the rub. A bolt on pre-engineered procharger kit for a new car is $5-6k parts only. You're going to need all of those parts + the engineering / fab time at likely $100+ an hour. That could easily end up at $10k installed not including getting a built trans to actually hold the power.
