How a Centrifugal Supercharger works

[Super Matty P]

mine will not make hardly any noise....sorry. It's internally belt driven and not gear driven. I guess this would be a plus for the "stealth" crowd though. No gear whine, no bov woosh, no visable FMIC = easy kill right?? nope!

Natey, I think everyone here is missing the forrest for the trees. Have I not said since day1 that I'm wanting to do this supercharger to enhance the overall driveability of the protege? Everything argumenative being brought up has nothing to do with original goals. The car will be faster, it'll pull hard, it won't stop pulling hard, it's cheaper, (IMO) it'll look cooler, it's unique, etc.....

I bet if someone other than me was doing this exact same project it would be the greatest thing since sliced bread.

I didn't think that this blower was drivin by 800* exhaust gasses. If I'm right on that, and the oil that runs through the scalding hot block doesn't go into the blower at all, then how would the charge temps be even near that of a turbo?

Nick, you're going on and on about the "right sized" turbo, but then you keep saying that "psi vs psi" a turbo is better. But if one flows 1000 cfm at 12 psi and the other flows 500 cfm at 12 psi, which do you think (use your brain here for once) is going to make more power?

Well, one is going to flow double - but the tuning is where you're going to make power.

You're exactly right Micah....I'm using the tried and true Haltech F10X stand alone fuel controller. It's been proven VERY reliable ad capable of very nice power number on turbo kits. Juan has used his (with race gas and 20psi) to a 12.5s quartermile. I'd say his tuning skills are quite good.

Did I mention that I'm flying him up to my place for the weekend to tune my supercharger kits??

I knew people would be skeptical so I made the third video showing my car fully warmed up and I wedged my hand between the blower casing and the header to show how little heat was actually transfered. I thought more people would've seen that video by now! I know you have Miller...I mean other people.

People said you weren't a post ***** when you first came back. Now you have 1/4 of what I have in 1/16 the time.

That's because he doesn't have any lag when he posts. (rlaugh)

48 hours to tune? - Stock up on the Caffiene. You should try to find a few members who are willing to be ginuea pigs. Maps all made for one car are going to be a bit subjective. I'd think maybe 2 more cars would let you see how the maps work on other peoples cars and get a feel for the difference between cars that are even stock.

In any case, I'm really looking forward to seeing what you end up with.

The haltech adjusts fuel based on a mathematical calculation based on input from the auxillary sensors. Since it is pre-mapped for a turbo car all we should have to do is lean it down a bit to adjust for the charge temp heat that wont be there and see what we get on the WBO2.

Boost is boost and unlike a vaccuum based FMU this will continuosly adjust fuel values based on a pre-set list of "checks and balances". I don't know if I'm explaining this correctly.

It'll be easier to tune than you may think. It's only going to need small adjustments.

For what it's worth a centrifugal makes so little heat it's almost ridiculous. Turbos and twin-screws have a long way to go and many an intercooler to add before they get to the LOW temps of the centrifugal, so that is a non-issue.

 

[Rism]

Jesus christ people as soon as matty knocks you down on one bulls*** point youre trying to make you come back with another one such as, "What!? Youre tuning it on one car? Thats not going to work!" And again you got bitched slapped because you knew nothing about how the haltech works.

Whats your next complaint gonna be?

And how did twin screw SCs get brought up in a thread about turbo lag vs SC lag?

Matty has said time and time again he will let his car do the talking so (fu) and wait for the dyno numbers.

 

[KpaBap]

Easy there cowboy, twin screws were brought into the discussion because they're the type of supercharger that always makes full boost from 1000rpm on -- you know, as in, they have the least amount of lag.

Had you not been blinded by arrogance and a lack of comprehension for the English language then you'd have known that.

Your whining and ass-kissing really has no place here, as I doubt Matty will give you some sort of special service because you "defended" his holy works in some thread with your tasteless insults and lack of coherent thought.

ad hominem attacks (cool) always the best way to win a argument. Anyone who reads this thread through can see half the people in it are just looking for an excuse to put down mattys kit. Im just pointing that fact out.

The air gets hot as it is compressed. The turbo has a hot side and a cold side. Some turbo get as hot as 1,600 degrees on the hot side. The air temps on the outlet may get to 250. The SC will give you hotter outlet temps then a turbo. I understand why you think it is not the case. It may seem hard to follow but thats the way it is.

It is hard to compare the CFM from a turbo to a SC. You get alot less power loss with a turbo per lbs of boost then you do with a SC per lbs of boost. It does not matter what the SC is spec out at. It matters what rpm you will run the SC on any given engine. If you pushed 1000cfm into the Protege engine it would last maybe a second or two. 1000cfm is good for almost 700hp. It is a hard target with a SC. You do not have a wastegate so you need to play with pully size to find the max boost you want to run. You may have to suffer at the lowend of the rpms in order to not over boost at the topend.

I see why you think this way but again it does not work out that way.

There are tradeoffs in both systems. In theory, a turbocharger is more efficient because it is using the "wasted" energy in the exhaust stream for its power source. On the other hand, a turbocharger causes some amount of back pressure in the exhaust system and tends to provide less boost until the engine is running at higher RPMs. Superchargers are easier to install but tend to be more expensive.

In the last 2 years I have seen the turbo manufactures setup and produce turbo's for the aftermarket.Awhile back turbo's were built for Diesels and people would pull them off and put them on the gas cars.Lag was an issue because of turbo sizing and designed principle(designed for diesels).

Now with turbo's designed for gas and the aftermarket LAG is a thing of the past.If the right turbo is sized, there isn't lag.My Sleeper kit uses the GT28RS and from a stop it hits 1psi at 1900rpm's..There isnt lag.
Compare the GT28RS(New technology) to a Super60 T3(old school)...The GT28RS is newer, No lag,flows 35lbs a minute and is good for roughly 350HP while the Super60 T3 is quit a bit older,flows 25-30lbs a minute, is good for roughly 250-300hp and doesn't start to make boost until 3000RPM's on a 2.0L.But yet the Super60 T3 is considered to be bigger..
Turbo turbine wheels can come in different configurations( P-trim,Clipped P-Trim, Q-Trim,etc) with this in mind and properly sized there isn't lag.As for back pressure.Many things can effect this.Manifold design,size of material,Downpipe size, turbine wheel,etc.

MPNick you obviously have no idea what I'm doing or the details of this kit. Your previous post is not applicable at all.

The blower I'm using flows almost 1000cfm at 12psi. Nowhere did I say I was going to run 1000cfm. I just said it was possible with this blower. I was pointing out how much air this blower will move at LOW RPM...This is my attempt to show the masses that no matter how much you try to say my kit won't be good that you're wrong.

Do NOT get into the "intake temp" debate about a product you know NOTHING about. The powerdyne is the coolest running blower available even at high boost levels. Don't try to tell people that compressing air will create turbo-like intake temps this is NOT true and you damn well know it.

I know you feel threatened by me and what little influence I have and I don't blame you. Keep swinging for the fences and MAYBE one day you'll find some way to discredit this product.
