4 rotor engine
I want to build a four rotor engine, whats involved i.e
Ignition system, joining extra rotors etc |
if you have to ask you can't do it yourself
get out troll |
Oilcan: Pvillknight7 has hit the nail on the head. No offense oilcan but you haven't a clue what you are asking about. The rotary engine isn't just a case of stacking, or joining, as many rotors as you would like. For a 4 rotor engine the e-shaft alone is going to run you over $10,000, the engine management system will cost another $5000 and those are only two of the many expensive parts that you will need. Then there is the issue of getting the engine into whatever car you dream of putting it in. So unless you have $60,000 to spare and have training on how to at least rebuild a 13b engine properly (ie: tolerances, procedures, etc.) I would forget about it.

I have seen 4 rotor e shafts for 8500$ soloracer951, how much would a tec3 cost?

Ya know, if you guys are just gonna pull numbers out of your asses, you should at least try for the ballpark. |
4 rotor engine
thanks for the advice chaps but having built a number of engines, one of which was to bike engines put together to make a v8 I don't think this will put me off.
what i need are websites and informative informatiom so that I can build this engine. I have been in the motor industry for over 35 years so know a few things. (machined the first set of dies for porches 944) Did some work on bugatti to. Anyway any info would be much appreciatted I know I have a lot of studying to do. The electrics don't worry about got a real good guy for that. Sorted v8 for me. Thanks |
im glad somebody has the credentials to put people in there place. i am moving to australia soon to be a pro athlete, but i too am going to build a 4 rotor when i get over there. here are some websites i found helpful.
www.kiwi-re.com, http://cp_www.tripod.com/rotary/pg03.htm- this will give you some basic knowledge. ( i found it interesting anyways), http://rotaryengineillustrated.com/4...02-series.html. also on the tripod website look up the weird ideas section. they talk about keeping the secondary ports open on a peripheral port. re-amemiya has done this many times with his pp 3-rotors. will post more if you need when i have time. |

Do you mean the side ports:dunno: |
Sorry if I came off a little harsh. Here are some pics to keep you motivated during research and build
|
here are some sites you should check out:
http://www.rotaryengineillustrated.c...orks/index.php check out "rotary engine building and porting" section on this site: http://www.nopistons.com/ search for 4 rotor |
still sure you want to throw money at this project?

Or $1600 for the flying lead E11v2, as you just send the box to haltech and they set it up for a 4 rotor ignition and injection setup.

And I was offered a used one in Japan for $10,000 whereas a new one was $15,000+. Even if you managed to find one for $8500 it's not that far from the $10,000 quote that I gave earlier. Give me a break already. |
lol, solracer, adding extra rotors and housings is MUCH more feasible than trying to turn a v6 into a v8. for the latter, you'd need a whole different engine block. As for making a 2-rotor into a 3- or 4- rotor, you just need additional housings, rotors, and a new E-shaft
|
i.e. some parts are reusable, whereas maybe the pistons from a v6 could be used in a v8, but nothing else.
Oh, forgot to mention ecu/ignition would be needed for 4-rotor |

I try to stay away from cursing on this site but....
DAMN WHAT A GRUMPY FUCK! You shooting for twat rocket of the year there solo racer? You know according to your logic we shouldn't try to do anything unless we already know all about it... So I guess we should all still be cavemen then?!? Shit, two years ago I was introduced to the rotary concept and now I'm building my own 20b. If I had listened to shit heads like you when I was getting into wankels I'd never have learned anything... Oh and a stupid question is one that is erroneous or shows complete and utter ignorance of ones ability to think. Asking about joining rotors and trying to understand the basics of a four rotor engine is an excellent question for someone who has no advanced knowledge of a rotary engine as it gives him the opportunity to understand that more than just joining rotors is required. However asking if it "sounds fair to you guys" that you act like a bullying 2nd grade ass fuck to some guy trying to learn something new IS a stupid question especially when you specify that he should learn the basics before asking about four rotors!!! Now how pray tell, Lord of the douche, are you supposed to learn the basics about something without asking questions?!?! Is he supposed to just sit there and meditate on the idea of a four rotor?!?! Maybe you didn't pull those numbers out of your ass but your brain certainly made its way out the back door after you couldn't get your mind off the dick you had up there! People like this guy almost stopped me from buying a RX-7 two years ago... Oilcan I encourage you to build a four rotor just to spite this cock dyke... If you need any information pm me as I have been preparing for a four rotor race build after I finish my three rotor daily driver and have alloted a good deal of technical information. |
the 4 rotor has been done before. all the information you could want is available.

they make a 4 rotor engine, or at least they have in the past. |

Just scouting around I found 2 site that sell the E shaft for 8,500$... 10,000$-8,500$ you got 1500$ you can spend on something else, rotors, housing's, or you could put it towards a stand alone! So there's your break Captain :) |

"4 Rotor Crank Kits $9,500.00AUD = 8,253.33 USD The 4 rotor kit has the following:- 1:- Eccentric Shaft 2:- Front counter weight 3:- Rear counter weight 4:- 2 x Centre plates 5:- 2 x Stationary gears (modified) 6:- 2 x Stationary gear carriers 7:- 2 x Stationary gear external oiling mods 8:- Rear main nut 9:- 2 x eccentric shaft end caps" Building a 4 rotor won't cost 60K Even Kiwi's 4 rotor KIT isn't $8,500 |
Yea that was one of the site I saw the eccentric shaft :) see soloracer you fool
|
sounds like a good deal. I wish they had a picture of their kit.
