I'm intrigued by this and good going for trying but I'm skeptical of whether or not it works, I've been interested in doing the same thing but I can think of many problems. I would like to ask some questions and hopefuly get a better understanding of how it works.....

1) The concept of the 2stroke is that both the inlet and exhaust ports are open at the same time. If so how can any pressure be built up?

2) how have you made the turbocharger, the parts like bearings impellar, housing must be so small and fiddly?

3) What rpm does the impellar spin at and does it actualy build up pressure?

4) Have you had to ajust the fueling to cope with the extra airflow?

5) Have you got a device which allows the turbo to spool up at a certain revs or is it boosting at idle?

Cheers I have some more questions but can't think of them right now. If one of the nitro guru's could speak to me on msn about this I would be very greatful.
havent forgot about this thread, it'll be around soon. there has been alot of work in making the impellers light enough without melting down on the exhaust side I had to make a move for a better job opportunity, and in the process my Mill suffered a hit that broke the 4th axis stepper motors mount, (but most of you guys dont even know what a stepper motor is) Now i have changed the turbine metal to another type that is more expensive, but i can make it lighter and still be as strong...

as for the post quoted above, finally someone is asking the right questions.

answers

1. restriction in the exhaust makes this work, its not as much about pressure as it is airflow (hint ) also, the rpm is so high, that there is alot more that makes this thing work than a big 2 stroke. I could write a book, but i dont have the time.

2. yeah, making the parts is a Pain in the arse, small ceramic bearings are $$, But on the machining side of it- let me just say that it is awesome what a HSS endmill 1/64" in diameter can do

3. cant say for sure what it spools at, my guess is about 10,000 rpm, and the max rpm the novarossi (that i had to balance) has seen is 65,000 according to the gear calculator seems like the rpm doesnt hurt as much as the strain does, but that is another book of information in itself.

4. yep, auxillary fitting on the boost side of the compressor.

5. the turbo spools normally at the same rpm under acceleration, 8-12000 rpm is an educated guess. if you take it easy, it is more linear and doesnt boost as much, but open the throttle, and its there. remember, this is the most basic of turbo setups, no aftercooler, no boost control, all that stuff would take years to make work, even then, it wouldnt work right... i have already spent that much time on getting the impeller design right, and IMHO it doesnt need any extra bs.

I havent been on here other than to read my pms, i am tired of all the BS posters, and I am going to be the one to laugh last when this is on a record breaking car next year in Cali.

later, jim

that's got to suck, breakint the 4th axis mount, i guess you can't mill one, can you Can't wait for you to get this think done, should be quite cool

"project turbocharger" yea that sounds pimp, also can someone help me... my engine shuts off after about 25 seconds of running or about the second full throttle, can someone help. Does it need the fuel priming line from the exhaust to the gas tank?

Dude.... no offense, I read from page 1 to end, and you are "licking" good to 1badtransam..... I personally prefer this kind of attitude in corporate culture up to certain limit. ..... however I respect more who bring me results than sweet compliments.

But don't you get bored waiting the heavenly promise
from 1badtransarm ?? still no single picture to prove his words.

I don't care if his invention work or not, all I need some photos to prove somekind of dedication to turbo engines.

I agree 100% most of these supercharging inventions are just a way to get a buck, they have no performance values.
