It's great that these guys are stepping up and developing new products and seem to have had success thus far, but I'll personally be convinced of that when they answer the questions posed earlier by DelSlow and when they have successfully testing a set in long-term street use. As you guys know, cooling is very important in our high temperature sensitive engines and to remove rotor's internal oil cooling, which reduces the surface temperature of the rotor faces, might increase the engines tendency to knock. And last time I checked, rotaries don't like knock too much.

Unless I'm totally missing the point of these and they are race only/methanol only... in which you would be correct, and they are awesome.

 

Well this is in Race car tech/Drag racing after all.

 

i thought methanol and aluminum don't go well togethere? Wouldn't it eat up the rotors over time?

 

so if all it does is spin why does the ecentric shaft have a stroke it would not need to be there. so yes it does rotate AND reciprocate.


and i see what your saing about the burnt gas pressure but you can not ignore the fact that that is not the only force acting upon it. in fact there are 2 differennt sets of bearings. so yes the force on the main bearings IS EQUAL because of counterweights. the force on the rotor bearings IS REDUCED because of less mass.

maybe thats where we got wires crossed there PMR

and for those people that dont care why it works i feel sorry for you...best of luck at mcydees.

even though at the current moment these are being designed for drag use, i still believe that other applications should be tested as well. especially the street/auto x/road course areas.

after all the world we live in revolves around money, so broadening the rotors applications, would broaden the market for these rotors, which of course means more sales.

that plus these would make a vast improvement in road course times and abilities, it could very well mean that a 20b could have the same weight distribution as a 13b.

it is after all what mazda was thinking from the begining when they developed the Rx7, a lightweight sports/race car with near perfect weight distribution, awsome turning ability, light compact engine, with the ability to make more power then most conventional engines of the same size

the 787b was banned because it was that amazing, imagine how much better it would be with these.

the point im trying to make is, there are more advantages than just to drag, they should be explored...

for all we know, this may very well be a way to break the dark cloud above our heads....because all people see with us is: "they break down all the time" there bad on gas"

i dont no about you guys but im tired of being knocked by dumbasses who think honda are better

and it would be sick to rip down the street at 12k!!! lol

 

How many people do you know that are willing to spend 4k on a set of rotors for the street? One thing I learned along time ago trying to sell rotary parts is that the typical rotary owners are tight wods.

 

perhaps, but people that are heavy into circuit, will want the exra long powerband, and will have the sponsors to do it

and on top of that there are people out there that are willing to drop the dough to get that extra power.

hell i would! but i am more focused on getting and FD first then ill worry more about that.

but the only way i would buy this is if it would last just as long if not longer than the conventional rotary engine...because i think its cool as hell to rev up to 12k or higher

 

They just got done running them for the first time. I'm sure further testing for other applications are in the near future.

 

pmr - thanks for the reply. That is along the lines I was thinking.
If you hold the amount of air constant and reduce the amount of fuel needed to create the same effect, wouldn't that result in a leaner air/fuel ratio?

Internal comsuction - I missed your "why?" question, but pmr's first sentence is how I would have answered you. Are you following me on this now?

In general, this is more curiosity than anything else.

 

i dont doubt it, i only posted my thoughts simply to show that others are interested, because the original and primary thought for this new item was drag only correct?

 

Air is not constant, you require both less fuel and air
A/F is "constant"
You might look at this as having the throttle slightly less open (less air going in now)
So you have less fuel, less air and less energy (because fuel and volume is smaller) but you are getting the same angular acceleration on the shaft because the rotor is lighter requiring less effect to rotate it
Hope that helps

 

The only reason I asked "why" was to get your answer on it..... I understand the thought process behind the qustion. Thanks though.

i hope i didnt sound rude, it was most certainly not my intent.

and if i did i apologize.

 

You're fine

man i feel sorry for the honda all motor class, they wont no what hit them,its bad enough they add weight to the car to keep us close to them but keeping that weight and making them rotors lighter we will be so far head of them will **** them off and they will have to go back to the drawing board to make there k motor even better. which wont be any time soon, i would like to see these rotors in jesus car

 

There's no such thing as a Honda All Motor class!
And the truth is they would either impose more restrictions on the rotary or just let the piston camp progress without handicaps. You cannot have a level playing field with a bunch of cry babies!
Look who is having the last laugh now. No more racing period. Guess what! The same rotary racers are still going out competing and having fun while the rest are selling their cars and becomming drifters. Only a matter of time before they f...k that up also!

 

Well said Cris.... so true

 

So what kind of power do you guys think the new rotors will make with a peripheral port set up.

 

That's a very open ended question......

-J

 

at least 120 whp on stock intake/exhaust.

 

120 whp is very optimistic !

 

well, if someone will buy me a set, i'll install them in my 13bppt that i'm building.\

then we'll know.

 

has jesus got ahold of u guys yet about the rotors

 

That is a good question, why? Please let us know the answer when you find it.

All i can tell you is that we did it. We were the first to put this Billet rotor in an engine and got them to work after all of the negativity of the rotors being to soft or melting and so on. May this is your answer, no drive to make new things. some time people think to much on the maybe's. About the million of dollars and the 30 years, whats new? The rotor have not chage, the plates have not change, the seals have not change, only size. We are making the changes with all of our parts. Starting with our throttle bodies, then our water pumps, our ALS seals and now our rotors. This did not take millions of dollars only desire and love for the sport. Our goal is to come with new parts that will me this incredible engine an increase on performance and more life and this is what we do.


Thank you

The tech on these rotors is way over my head but the fact Eastcoastparts puts heart and soul into this says tons about there passion and love of the rotary!
People like this will keep new intrest into something i really love and enjoy!
THANKS!
