Modern Roots superchargers are pretty efficient and reliable. They compress the air outside the unit; when the bypass valve is open, it's basically shut off. So it doesn't disaffect normal driving. They are probably the most efficient designs below 10 pounds of boost.

Centrifugal superchargers are powered by the engine (belt or gears) and are much less efficient for street cars that often run at low and medium RPMs. They can be put together cheaper, and need fewer parts, and for some racing applications they work very well.
 
OP. Im sure your inquiry will spark some debate. There are many feel the PD type blowers are best, and many who favour the Centri types.
I only speak from my own experience. I weighed up the situation for several months before going the Procharger route. Here is why I went with it.
I felt that on a stock motor, the centi would place less stress on the bottom end, as the boost comes up gradually. I also wanted my car to retain stock driving characteristics, until I wanted it. I had traction problems in stock trim, even with soft tires, so I didn't see the point is adding to the problem by increasing the low end torque.
And finally, I really liked the way the Procharger looked in the engine bay, as it retained the stock strut tower brace and engine cover.
When I made the decision to go with the Procharger , cost was secondary. All superchargers are expensive. I felt that if I was going that far, I would get what I wanted. True enough there are variables in relation to power and torque. But honestly, when you decide to supercharge, all of the major brands will produce more than enough power for a street car, at comparable boost levels.
I personally think its nice to have so many offerings and have the options to personalize your vehicle.
So do your homework, and get what YOU want. They all work !:winks
 
I don’t think there are any roots superchargers available for the 5.0. I’m not even sure if there are any roots improved units available. You can on the other hand get a TVS blower, which you could argue is a “roots” blower, but it’s really not. So your choices are:

TVS
Twin Screw
Centrifugal

I would stay away from a Twin Screw for a street car.

Now to your question:

If you are looking for a technical reason why one is better than the other you are out of luck. They both (TVS vs Centri) have their advantages/disadvantages. And you will get opinion from both sides. At the end of the day it comes down to how they feel/make power. Some people love how a TVS blower whacks you right in the rear from effectively zero RPM’s. Some people like the way Centri blower build power through the rev range. It’s a blonde or brunette thing. They’re both great, just different.

Here is the best advice you will get (if I do say so myself). Get a ride in or drive a car with each and then decide.

My personal opinion (I may as well serve it up, everyone is going too). A TVS is a great daily driver/street car blower (there is a reason ALL of the OEM's use them). The centri blowers are more suited to racing.

Sqidd. I always respect your input. I know you are experienced. True enough, the Centis shine in a racing situation. But they are also well suited to a street application, in certain situations. Granted with motors that don't make a lot of low end power to begin with, adding a blower that makes lots of low end torque is best. But with the new 5.0 Coyote, it makes about as much low end toque as can be expected from a motor that size.Even in stock form, it is more than capable of overpowering tires in a street situation. So a centri, in that case would be a great way to go , even on the street, as the power comes on more at the top end without contributing to an already present traction problem. And as a bonus, the centris allow the car to keep its stock street manners, until wanted otherwise.
Just saying.

If a car doesn't have a "traction problem" it isn't much fun to me.:winks My 2007 (which has very, very sticky 315's and high gearing) will SMOKE the tires off from 50mph and spin them well up past 100mph. Another couple hundred HP and it will be just about right.:grinroll:

My 2012 feels like a gutless turd to me.

That said I raced 200hp/375lb Superbikes with a contact patch the size of your hand for 10yrs. My idea of fun would be considered scary by most.

And that all dovetails into what the individual wants out of their car. Like I said above, both types of blower rock. They just come in different flavors. thumbsup3.gif
 
Thinking of supercharging my 2011 5.0 mustang anyone have any recomendations on what to use and what not to use
You can't go wrong either way, but I'd either recommend this:

11-12 Mustang 5.0 Edelbrock E-Force Supercharger 1588 | UPRProducts.com

if you want that infamous TVS torque,

or this:

11-13 Mustang 5.0 Procharger Supercharger HO Kit 1FR214-SCI

If you want that high end rush.

Just remember you'll want to upgrade your suspension to handle all of that extra power. That's where UPR saves the day with great suspension backed by a Lifetime Guarantee.

Sharad. For those that do have a supercharger. What are your recommendations as to what suspension mods are best to do ?

Believe me sqidd, I know exactly what you mean. Because I feel the same way. :bigthumbsup
 
Sqidd, what are your thoughts on the Sean Hyland TVS? Saw one used for sale (bnib) at a big savings. How would you compare it to either a roush or vmp?
 
As a ProCharger owner I prefer the progressive boost both on the street and at the track. The 60ft times aren't spectacular but they're respectable I figure and they should get better with some more adjustments. Like sqidd said above, the best thing would be to try to get a ride in cars with both setups and see which you like better.

Inlet elbow is way too small and limits the ability to upgrade to bigger TB's.

Looks to me like the fittings on the intercooler are way too small. And this is a HUGE deal. Making boost is easy, keeping it cool on the other hand is the trick.

If I were putting a PD blower on a 5.0 street car it would be a Roush, or a Roush......or a Roush.

Exactly. You get what YOU like. Ive been In, and seen quite a few Mustangs with different blower set ups on them.
I find that even when my car was stock, the revs came up very quickly. I personally love the way my Procharger starts making power at around 4000 rpm and goes to maximum boost once the car is hooked up.
And Ive been told by several people, that it looks right at home, in my engine compartment. :winks
 
So, a twin screw SC will give you power and torque from 0-3500 rpm and the centri SC starts generating power around 3500-4k rpms?

Yes. A PD type blower will make torque instantly and keep it up till you get off the gas. They make maximum torque at far lower RPM than Centris do. And with the Centris, the torque trends to build gradually, till you get to maximum, which is usually less than a comparable PD blower.
But both make enough torque, to get the job done. And they both make power. The Centris just come on gradually, rather than making an instant hit, to the drivetrain. Which is what I like about them. Especially on a stock bottom end.
That is why the PD type superchargers are better suited to automatic cars. When you have a clutch which allows you to control the revs more intently and a heavy flywheel to build up momentum, the Centris tend to shine.

That being said. A good comparison would be an automatic car, with a torque convertor verses a manually shifted vehicle with a clutch. The automatic, with its "fluid"coupling( torque convertor) is a lot more forgiving and allows for some "slip" where as a standard with a clutch, tends to "shock" the drivetrain more severely as the power connection is either in, or out, with nothing in between.
So, on the starting line with automatic, you stab the gas and the revs come up gradually, with no driver control. On the other hand, with a standard, you can "leave" at any RPM, that you want. Which is the main reason I prefer Centris. They don't pound the lower end of the motor with a lot of torque at low RPM's.
:smartass:
 
I live in DC, which isn't too far from you (if your profile is correct). If you want to see what a Roush TVS 5.0 is like, I'd be more than happy to show you, just let me know.

I've been looking at the Roush, and now the Ford Racing Whipple since they upgraded their drive train warranty. Why would you recommend the Roush over the Ford Racing one?

I'd defer to smart people who know lots more than me (like sqidd), but I understand that the Whipple is a Lysholm screw supercharger that compresses air internally, so it can't be shut off with a bypass valve and burns fuel to drive the supercharger all the time, so it runs hotter too.

I suspect the Roush is not a Lysholm, but I don't know. (I bet sqidd knows.)
 
Sharad. For those that do have a supercharger. What are your recommendations as to what suspension mods are best to do ?
At a bare minimum, if an S197 owner is looking to do some drag racing on boost, I'd recommend adjustable shocks like these:

2005-2012 Ford Mustang Strange 10 Way Adjustable Shock S6008LM - UPR Products

And control arms like these:

05-14 Mustang Pro Street Urethane Lower Control Arms

11-14 Mustang Pro Street Double Adj Upper Arm & Mount


Our shop car has cut 1.35 60-foot times on this setup and drag radials.
 
And then there is the old" how much is too much" debate. I don't spin much in first and second because I'm usually trying NOT TO, but today I found out I can also spin through 3rd and 4th (smelled the burnt rubber from a 4th gear 60mph" burnout" for 5 miles after the fact) something I'm not accustomed to as being a problem so I do it easier as I'm more aggressive at those rolling speeds.

Which ever you do, I suggest you go ahead and build suspension and tires/wheels into the budget.
