He bought it lock stock and barrel so to speak. It was an older guy that had owned it since WWII literally. The old guy admitted he didnt have a clue as to what was in there. BUT he is also Ronnie's Dad's friend so he probably doesnt mind too miuch. I do know Ronnie paid a close to $500k for the place. And I know from being a machined parts inspector when I got out of the USAF that the machinary in the shop is at least that much.

HE got one hell of a deal.

 

You too buddy. You got a hell of a deal too.

Don't waste your time trying to machine solid rod titanium to an e-shaft, it'd take an ungodly amount of time and lots of broken tool as titanium is very hard to machine. Titanium is very stiff for its weight, but high strength steel as well.
If I were you, I'd try to probably sell it somewhere... kinda hard finding ma and pa shop who wnats to buy that stuff but hey you can try.

 

umm ever think about using an accumulator for pre-start oil pressure?

 

I had thought about some sort of electric pump for a dry sump system since the pan would also need to be fabricated but sheet metal is easy work.

My concern is what can I put a 4rotor in? its gonna be one hell of a long engine. It will nhave to be something with an I6 or a V8 stock. I doubt an FC can accomidate it.

 

Oh yea I got the design for a 4 rotor shaft 90 degree firing should be pretty smooth running 1-4-3-2 firing order.

 

you just need to get creative, we had thought about this with my car, with 2 13b's or a 3 rotor that didnt sit any farther foward then the stock engine, then were like umm its really not worth the time for a street car to dog house the firewall, so if you wanted to notch the firewall, move the engine and trans back, and have it sit like a 3 rotor. so what if you can use the stock hole for the shifter or console, you'll have a 4 rotor fc, you could mount the radiator horizontal farther up in the engine bay.

 

Yep, galling is a major concern in additional to the expansion characteristics. I dunno what "3032" is, as most Ti pieces I've seen are 3 digit coded. Forged cores + heat treating makes for a very strong piece. Chrome lobes aid in lubrication. I think we're attacking the problem in the wrong manner, why try and make such a thin, long metal piece stronger? V8 cranks don't flex due to their main caps! Redesign the engine to run bearing support centers and the flex problem goes away...

Do you think a main bearing betweent he 2-3 rotors would be needed the design is simply a CAD drawing so far so changes can be made easy enough.

 

Some Japan shop (Top Fuel?) designed a roller bearing system where the center housing of a 13B was supported by a roller/needle bearing. Performance was promising, but I think it costed too much to machine (requires modular e-shaft with removable lobes) and not too many sold. This system basically eliminated any of the damaging resonances at very high revolutions. Also, the rotor bearings were all converted to roller/needle bearings.

I belive that Guru Racing in Aus. makes a 2 piece E-shaft with a bearing in teh center housing. The link

 

That would be Scoot.. very expensive, but I hear they still sell them..


and using Titanium for a e-shaft is a bad idea, It will eat the hell out of the bearings on start up and if the engine lasts more than a 1,000 miles I'd be surprised. Also after it eats bearings you shaft will be junk. you should also take in to consideration heat expansion. Not sure, but I think titanium will expand more than steel when heated and then you've got a seized and spun bearing for sure. I like the axel idea personally, that would be sweet. Transmission output shafts would be a good Idea as well since nobody seems to sell them unless you buy a whole transmission and I need one for my OS Cross that uses the stock output shaft on my 20B car... I see it going poof soon...
