I understand what you're saying on that note. There was a guy "stal" on the other forum that runs his car quite a bit. He went from a built centri 2v car and eneded up selling it and getting a 04 cobra well long story short he got rid of the eaton for a TS pd blower he said time and time again that he loves the power the only downside is the heat it creates after a couple of runs and how the ecu pulls timing after that and therefore we know its down on power after that til it cools off for quite a bit. he said it does it quite a bit more than the centri setup on the built 2v he had. So in short the bonus was the low end grunt but the downside was the heat in comparison after running it hard.

I have a question. Why do manufacturers (Ford, Mercedes, GM, etc) use pd blowers instead of centri on most of their models?

Eaton only produces OEM (factory, from the dealer) type superchargers. http://www.eaton.com/Eaton/ProductsS.../FAQ/index.htm

the two fastest production cars One Bugatti runs turbo's and the Koenigsegg CCX run a modular ford 4.7 liter with guess what form of FI? Two centri blowers.

The question is why ppl tend to ditch those eatons and sell them.

People make it sound like centris have boost lag or something like and old turno which isnt true, u mash the pedal WOT and its instant boost.

Ok thats what I wanted to know. So it kinda really doesnt matter what rpm's the power is because if you want, you can just control your pedal to when its needed? If I were cruising on highway at 70mpg, If i mash the pedal, its there. If im at a red light, If i mash the pedal, its there! Right? Only difference is when your not mashing the pedal you will feel as if there was no supercharger with a centri?

That about sums it up. Bc the power will be there its just a linear build of power all the way to redline. Uber nailed it some ppl just make it sounds like centri's have this big lag when they dont. it takes hardly no time for the power to come on and if you're on the highway with a centri you will definately feel it even at 1/4 throttle or less but usually when I travel from Tx to Ga I only see boost about 3% of the time max bc I play around sometimes other than that its easy sailing but the power is clearly there . Not nocking the PD blowers but it seems like there are some rumors out there about how the power isnt there on a centri. Even from a standstill with a centri you can roast your tires with no problem at all through 1st and part of 2nd gear.

+1

100% true. That was my first misconception when I got it as well. I remember I floored it and the boost was instant and I was roasting 1st and 2nd gear. It caught me completely by surprise and almost made me hit a tree the day after the install. Centri blowers make power everywhere in the rpm band like all other blowers but they make their peek boost at 3k on the p-1sc models. The more boost the sooner boost comes on. I know at idle my procharger is providing me 2 pounds and I have a pulley meant for 10pounds. I remember that I tested this theory on the highway that it would come on instantly and I downshifted. Needless to say I floored it after downshifted to 3rd gear and the very moment I did I heard that centri blower screaming and the power was instantly there. In a matter of moments I was at 90mph and I shifted to 4th gear and didn't let up but neither did my blower. It screamed up until 120mph and it only stopped because I let off the throttle. I was in peek boost the entire time. If you only lived in Miami fl I would take you for a ride and literally show you what centrifugal blowers do but you live a very long distance away.

Because they work great, last a long time and give people power low in the power band where it can be used on a street car (or a part time race car).

Even in the Mustang world, look what the major players use for their cars:

SVT: PD blower
S197 Shelby GT500: PD blower
Saleen: PD blower
Roush: PD blower

Thanks. I was thinking that there has to be a reason why Ford, GM, etc choose to put pd blowers on their factory models instead of centri's.

The gt500 makes over 600hp and has an Eaton strapped to it.

The only car that i know of that comes from the factory centri FI is the Koenigsegg CCX 4.7 ford mudular v8 and it has centri blowers as its form of forced induction

And it runs what in the quarter...low 12s maybe mid 11s??? Look at a ysi or f1 mustang setup in that hp range and let me m is what that's running. Not here to argue just to show that just because it comes from ford with a certain power added doesn't mean squat.

Spot on. Thats what upgrades and the aftermarket is for. Alot of ford cars come from the factory with factory installed parts that eventually gets sold for upgrades.

Yeah, because quarter mile is the only way to tell the true level of a performance car. (-Insert facepalm here-)

Tell that to Jazzer as well then. There have been plenty of mustangs winning in scca competitions as well.

The Mustang makes a great road course car. Saying that is like saying it's dumb to drag race a 3300 lb car. I'd love to see you walk up to the AI guys and say something like that. LOL. Weight reduction and suspension mods go a long way in both cases.

I've had two Mustangs that I use(d) for road course. The V6-R would hold it's own with the high end cars (Vetter, Porsche, BMW etc...) just fine. Good front/rear weight distribution, great power band and enough suspension/brakes to carry the speed deep into the corners. The black one is more just a 'fun' track car since it's primary duty is my DD. Def no slouch around the twisties, though.

I'll tell it to all 5 guys across the country that wants to hear it. Of course you can build a car to do whatever you want it to. Look at its platform, it was not intended for twisties. There are 5000 other cars before mustangs that were. End of story
