I get the "If its so good then why isn't everyone doing it" about my car all the time. far be it from me to pass it on to you. I am a research engineer not a design engineer, I was just following my logic/paranoia. Carry on thou brave soldier. Fight the good fight of Forced Induction. When you emerge victorious may you be hailed as a hero to the rotary world. Maybe then your gf and I can hook up for a photo shoot together.

Well I think we know why he disappears for a while from time to time....a women in chaps around here (Texas) gets all the men excited.

Richard Paul,
If you need a car for mock up or R&D I would be willing to let you use my car. I am located in Valencia so I am literaly a stones throw away from you. Let me know if I can help in further developement, I would like this come to fruition as much as anyone in this forum.
Regards,
TK

RP... Must Post.... Getting Weak... Need Sustanance.

Wow!
This post sure is dieing, Richard post something anything to keep us updated.

shelleys_man_06

He's been busy.

rotarygod

Chill out Tonto! Would you rather have him post updates constantly or work on and advance the project?

x-mann

work on , work on, post when too tired to turn a wench.

Struth - give the man a chance. It is not like he can walk into WalMart and get the blower and the pipework!!!

Cheers,
Hymee.

surely pep boys has what he needs?

Man, this should be easy. I saw an ad in the back of a car magazine for a SC that will increase my HP 25% and gas mileage 35%! And it was only $35.99! I don't see what all the fuss is about.

If you trust the quality of this product, go and buy one. Else wait patiently for a quality product... :D

Guy's, I'm real sorry but I've had this computer bug for about a month now and it really got me a few days ago. Couldn't get on the net. E mail was OK. Spent hours on the phone with my server, got nopthing. Took the thing back to the store. They did nothing and I finally picked it up. Just reinstalled The whole XP thing. Must have lost a bunch of stuff but don't know yet.

The first thing I did was log on to this forum. I knew you would be missing me, unlike some women I could name.

Anyway there isn't much to report. The two Rx blowers are done but not much testing has been done. The shop just got three big jobs and we have to do those first. There will not be any room in the shop for supercharger work for three weeks or so.

In the meantime I will spend some time researching the engine managment problem. I'll also keep my ear open to what is going on in the forum.

Thanks for the support, Richard

Liquid Rhino

Thanks for the update, Richard!
Work calls, I'm sure we all understand that. We'll be eagerly waiting!

Wow!!!!!

at first ... i thought i knew how the SC would work....
but now that i see the pic of the pieces again...
i'm not so sure i know how it works and how things will fit together,,,

is there n e one who is animation inclined,.. who would like to make a quick .gif to show everyone how it works?

or maybe someone can just explain it... "in A LOT of detail..."

thanx.

If you can picture what a jet engine looks like, this spins the same way. Some of those fins are stationary while others rotate. These blades are called fans and each segment consisting of one stationary and one rotating row is called a stage. Since this has 4 stationary and 4 rotating rows of fans, it is a 4 stage compressor. A 5 stage would add one more stationary and rotating row. It is basically the front half of a jet engine that is spun off of a pulley.

As air enters the first rotating fan stage it is grabbed and thrown into the engine or supercharger in this case. As the air leaves these fans, they hit the stationary fan stage behind it. The stationary blades are angled the opposite direction which causes the air to slow down as it switches direction. When you slow air down, you compress it. The next rotating set of fans grabs this slightly compressed air and slams it into the next stage of fans which compresses it more and so forth and so on. Each stage compresses the air slightly. Since these stages are in series, the total compression of the air through each stage adds up and is cumulative.

This may sound a little confusing but just stare at the pictures and look up jet engine design. It is really quite simple once you actually see it.

I'm glad RG answered that instead of me. We all know what a poor teacher I am. I tend to get too technical and babble on. So good job RG.
BUT, I can't let it go whithout getting more technical. He asked for detail, right?

AF compression works on the wing principal. It adds high pressure under the wing. Now you all learned that "lift" comes from the wing having further for the air to go on top of the wing thus forming a low pressure area. Well that is true but modern airplanes don't fly on that alone. True it is used to great effect on low performance planes like say a 172 etc. there isn't enough lift for the wing loading on most aircraft.

It's angle of attack. (AOA) Meaning there is enough power to tip the wing into the air and hold it up by the incresed pressure. Areodynamic shape as is discribed in high school isn't even present on fast aircraft. A fighter plane has symetrical shape airfoil. That's why they fly upside down just as easy as right side up.

Now the AF compressor takes the shape another way in an attempt to get more lift out of a stage. This requires blade shapes unlike airplane wings. And they are different for each stage sometimes different from rotor to stator. To do more work on the air the airfoil wil require more "camber". This means it will turn the air more.

As the air is compressed it takes less space so stages decrease in size as they reach towards the discharge. Thus you can see why more pressure just requires more stages. I don't know the limit but the GE F 101 engine in the B-1 bomber has 390 psi. I don't know how many stages that took because the engine is still classified. There may be newer info then I have though.

You can also grasp from this that more mass flow only requires bigger blades. You only need to look into a 747 engine and look at mine to get the picture.

So did I get technical enough and babble long enough to keep my image??

zoom44

i dont know. i completly understood everything you said. so perhaps more babbling is required?

Liquid Rhino

I don't know if it's confusing to some, but I'll tell you the parts I really like:

"Blah Blah Blah Supercharger Blah Blah Blah Rotate Blah Blah Blah Jet Engine Blah Blah BlahCompression Blah Blah Blah 747 Engine."

j/k, it's all really interesting! :p

Richard Paul

you didn't like the B-1 bomber or it's engine?

Liquid Rhino

You sure got me there Richard! LOL :D

Yeah, I guess the B-1 and it's engine get some props for cool factor as well!

Richard Paul

top of the cool list???

Now you need to show a picture of the SR-71 engines at full throttle. There's something about seeing mach diamonds in the exhaust that is just plain cool!

Liquid Rhino

Great.... now if I could just figure out a way to fit one of those Blackbird engines in my trunk...
Yeah! That'll surely get me a little closer to beating that 350Z off the line! Oh wait... I've got to find a place in my neighborhood that sells jet fuel..hmm...

Truthfully tho... I'm more than impressed with Richard's quick turnaround and R&D of 2 working prototypes. Whether or not this thing ends up at the top of the FI food chain, you really gotta give props to a dude for being on top of things! Our community waits steadily & excitedly on your progress.
