well since im just an na guy, im not sure about the tech info, what i am sure is that if all is as you claim it is, then you got me as a FOR SURE buyer.

Greetings from a brand new member
 

Dear Frank, I have had a similar idea brewing in my brain since I inherited my fathers '88 SE non-turbo. I have done some research into solid state thermo-electric cooling units(peltier devices)& was considering an active intercooler design to go along with an electric supercharger. I am an audio engineer by trade & have seen my industry revolutionized by rare earth magnets & the effeciency of this material in electric motors. I believe a active intercooler/electric supercharger has one real advantage over turbos - because they work from electricity they are not dependent on engine RPM's - therefore are not subject to lag & can be controlled much easier & do not suffer from heat related difficulties. I had envisioned a recirculating pressure boost- intercooler setup so that excessive pressure is recirculated back through the active intercooler again to boost efficiency & reduce wasted boost pressure - Kind of like a capacitor for cool air pressure - which would allow increased boost pressure without detonation. i'm new at this but appreciate any comment.

That's what I like to hear - a buyer already ;) ! I am now talking to my engineering partners at International Turbine And Power...our tech department (tooling and CAD design) are in Austin, Texas, as is our machine shop - and - guess what the machine shop owner runs - an RX-7 (3rd Gen, though). I really think this project has some merrit, and I am going to persue it fully. So...what I am going to work on is -
1.) Supercharger
2.) Turbocharger
3.) Intercooler (bladeless disk system to replace the current intercooler either supplied by Mazda or aftermarket)
All should work much better and cost considerably less than anything currently available.
Keep the posts coming on what I need in the technical department. You should see one of my partners (Martin Dorantes) chiming in with some questions and posts, shortly. I'm aerospace...he's mechanical engineering trained.

I read all this talk about superchargers. What about the Camden Superchargers? I hear all sorts of talk about those. What are your opinions?

What about the Camden Superchargers?
 

Old school (carb), high dollar..

Ramsees666,
Nice ideas, man! You (in my humble opinion ;) ) are totally correct about advantages of using an electric motor to drive the supercharger. It is independant of the engine RPM's and can be precisely controlled, thus affording an unheardof degree of control regarding boost and pressure to the engine. A simple computer program could be written to control all of the parameters. Right now, my RX-7 is hooked up to my laptop (not too sure if I have everything wired correctly though, and I had to borrow some stuff from a dyno we used a while back to test the Tesla Turbine). It's really the way to go, though. With the turbocharger, we can get quite allot more HP boost just from the fact that the Tesla Turbine will hands-down outperform a standard bladed unit (i.e. Camden or Paxton or Vortech - all bladed impellor driven units). No contest there. For the intercooler, we can probably lower the inlet temperature a good 90-100 degrees F. That's gonna make the engine just love us for that. Cooler air...more dense a charge. Simple - ya right. Now to get to work on the units, themselves. Pick this thought back up tomorrow.

Man I am droolin with the thought of this supercharger. N/A goodness forthcoming it sounds like.=)

Where do people get this stuff? Any proof on that statement? Have you actually done it? Please do not post things like this unless you can back it up with facts.

Aaron -
OK most of the driveline is great - but the NA tansmission input gear is "the >200 HP fuse" before long. O, yeah and the front diff mount..

Small world Frank;

I have been trolling the TT list for over a year and I just got a s4 N/A a month ago (for free, I'll post pics in the who got the best deal thread soon). I was thinking of making a TT for my rustang (now going up for sale this spring to buy parts for my rotary), but I could not figure out how to get pressure from the spreadsheet and got distracted w/ other things before I could get real deep into it. I work at a laser welding plant and our 2d welder can laser cut whatever for free. I'd feel better if I could make my own device, but one with a "Tesla Turbine and Power LLC" nameplate on it would be almost as nice.
Sounds like you are pretty excited about this app. so we should be able to see prelim results in a week?:)

I would think that being a TT list member I would get first dibs on a beta to test;)

I don't want to turn this into a driveline argument, but you are aware that the TII transmission and the NA transmission internals are almost exactly alike, right? The difference between the two is basically the ribbing in the case. And I'm not sure what you mean by "input gear". Perhaps you mean "input shaft"? I have broken one quite nicely, but it was due to lack of oil....

But that damn diff mount...ARGH! :)

Well, I have not been a TT mailing list member, but I was subscribed to the Tesla Coil list for a few years...That's gotta' count for something, right? :)

Anyone who KNOWS what Nikola Tesla contributed to our modern society in general gets one cheep ;) !!! Next time anyone switches on a light switch...there's Nikola Tesla. How about the coil in your car? Flourescent lighting...not to mention capturing hydropower from dams (i.e. Niagra Falls!). Hey, all's well. I just finished doing some basic CAD work for the units. Keep the posts coming in, and, if you ARE on the Tesla Turbine list (a Yahoo Group, btw, which I moderate and run) - you definately get one for below cost, because I KNOW how long you've been waiting. :)

Frank

he developed the AC power system.

"OC" wins a supercharger ;)
 

Seriously - OC got it right. But, I am still going to need allot of help from the forum's guru community to bring this idea of a Tesla bladeless disk Supercharger or turbocharger into reality. There are any number of technical issues to tackle. This has got to be the most interesting and informative forum (RX-7.com) that I have ever scene, and I have as yet seen a single "flame" post. Not too shabby, guys.
Now if I could only figure out why I loose my overdrive when I'm on the highway above 70 mph...works just fine below those speeds...then...whammo - highway driving - no overdrive, even when going downhill...freekin thing is driving me crazy. :cool:
My signature is now appearing with the mods I've already done to the car...took a little hint (actually, a BIG hint of an idea!) from "Aaron Cake" with his signature. We have GOT to get together and compare these two cars. :p:

count me in on this thing. I would just love to get some bleeding edge tech :)

as for how much cfm we will need @ rpm, ill have to do some research here.

active rpm should be 1-8500 or higher (the later NA cars have a 8 grand redline, but when i race i always happen to take it over it.)
im guessing its going to run all the time like a normal supercharger... i dont see any other way it would work smoothly.

make this thing so it has a lot of potential. someone suggested making it for really low boost, thats no fun!

Im thinking the superchargers controller should basicly read off of engine rpm. useing the tachometer output should work fine. What we dont want is to be making full boost at idle.
This way, when the R's go up, the charger spools up accordingly. A computer program could let you choose a virtual supercharger gear ratio, or what the max cfm/disk speed will be @ 8500 or higer.

I can see this thing adding some huge torque since it can spin on its own at low rpm. i hope this thing works out!

"OC" wins again!
 

OC - good points to consider in that last post of yours. I'll be online for about another hour if anyone wants to fire some info at me directly. Tonight - it's the local watering hole time. ;) . I need a break. The only thing I'm concerned about is the over-boost part regarding supercharging. Turbo's are easy - they are run from the exhaust - more output = more boost power. Since I will be running the supercharger directly from a DC motor, it will have to be regulated by some trigger (electronic) but I do not want to make it too complicated. I could probably put an electronic sensor right about on the pointer everyone has to set their timing and take the readings from there. Boost would be a direct relationship to engine RPM, and there could still be an inside control system for "max" boost and cutoff hooked to a guage. Most of you guys are not controling your engine with an IBM laptop like I am. And THAT was one of the biggest PITA hook-ups I ever tried to figure out. For anyone who wants to try that one, I started with a base program from a "Land-And-Sea" Dynomometer and went from there. Wankels are sure fun...;) . See ya...

where is the tesla turbine mailing list?

Frank, read this.

the second part is most interesting.

All I can say is wow...if this works out, it would really be a great thing for us N/A owners. Keep us posted on your progress, and thanks for giving us a fighting chance at finally making some horsepower! :)

well, im back online, and i've been doing some serious thinking, asi said befor, im a for sure buyer, and i think it would be awesome, i mean it would be a completely new system, something state of the art, and i think above alot of other systems. If the cost is as low as you say it is, then it sounds like the way to go for the na guys trying to squeeze hp out of their na. By the way, im not a member of this Tesla yahoo club, but if i join now, can you include me in the one below cost ( poor high school student) and ill be waiting as anxiously as anyone before. Besides im a member of the Rx7 community who's been waiting for a breakthorugh like this for a LONG TIME. Im gonna join right now.

All I can say is that if this thing flies, I'm there... Too many ideas don't have follow through. Not just on this forum, but in general. There are a lot of great ideas and minds out there, it will be nice to see someone do something for real. Please don't let this die -- put my name on the list if you make this thing work -- I'll be waiting!! Meanwhile I have some reading to do on all of this stuff. :-)

That tech stuff is a little too complicated for me, but if it's not too expensive I'm buying it! :)

Damn! Now im all hyped up about the idea. If that cooling thing would work out, it would be a front mount state of the art intercooler of the FUTURE! haha, for rex' only. I would love to make it a sleeper, like a cf hood but just like the stock na. Call it a Tesla 7! my imagination is wandering, hehe, come on, iknow you guys are thinkning it too!

First, let me say that I am not a mechanic, or really have a lot of first hand mechanical knowledge, but I get by. :)

This definately sounds like a great idea, but with all great ideas, the bottom line is money. You're obviously not going to do this just for the hell of it, and I'm sure you would like to make a profit (as well that you should). You said you would sell these at your cost, and if you really mean it, then I tip my hat to you :). The RX-7 community (for all intents and purposes) is a shrinking one, and most people who own one do not have the resources to spend large amounts of money for upgrades. I only say all this because if your intentions are to make large amounts of money, I think most people here would agree that you've chosen the wrong market (we're not talking about a $100 part here). ;)
Evil Aviator already mentioned this, but the stock alternator on our cars is pathetic at best, and any additional load on it is asking for trouble. :(
Considering the amount of time and effort that Aaroncake went through to Turbo his N/A, it would seem to me that with your device, it will be just as problematic. I don't think it will be a case of 'bolt it in and your ready', as there are a number of other issues that would need to be addressed (otherwise everyone would be turbo/supercharging their car).

Just the thoughts of a 'user', not a 'fixer'. :D
