I've always wondered, barring the limitations of an accessory drive/transmission, what determines the upper limit for rpms of a rotary engine? At a certain point, I'd assume how much air/fuel can be pulled through the ports creates a limit, but what limits it before that that you can't engineer past? Basically, paging spyder to the chat thread!

The ultimate brick wall is probably weight, failures are due to components being engineered to fit specific roles based upon the cost of the materials being used.

I don't know if I have the vocabulary to describe how I feel right now. My girlfriend said that when her father passes away she doesn't know if she'll be able to not think about his feelings towards our relationship. I get that she's an emotional wreck but that was not what I wanted to hear.

Yeah, at a certain point, the eccetric shaft and seals seems to be the weak point strength wise, I'm just curious at what point air flow or weight/friction becomes the limiting point barring failures. I kinda wanna know what a 13b wizzing at 20k sounds like.

At a certain point, I'd assume how much air/fuel can be pulled through the ports creates a limit, but what limits it before that that you can't engineer past? Hey I kno dis! Eccentric shaft and / or apex seals. The rotors are spinning at 1/3rd the speed of the eccentric so there's actually not as much rotational mass as you might expect. In a 13B, there isnt a centre bearing so the shaft can flex. Put in a centre bearing, the rev limit jumps to whatever seals you have. Normal seals are steel, the top line ones are carbon. On a 13B the rule of thump is 8000 rpm without seals and eccentric being done, the 12A can buzz 9,500. 10A is ...ummmm..... I've never heard of one being destroyed by over-reving. I know people who regualrly wrung them out to 13,000 rpm. On the stock carby and extractors, I'd pull 11,000 rpm on the old rally car occasionally. The next problem isnt in the motor, it's the flywheel. And umm.... have a guess how spectaclar that is when the flywheel fails? So basically the rev limiting items are apex seals, flywheel and eccentric shaft. Oh and clutch of course. But usually it's either spit out an apex seal or throw a flywheel. Edit : Also, lack of air flow wont stop the motor from continuing to climb in revs. It'll loose effiency yes but it doesnt have a valve in the way so air and fuel will continue to flow in. Better ir flow will help it rev faster but it wont stop it from revs increasing - the apex seals will fail first. CAT INTERCEPTOR fucked around with this message at 09:07 on Feb 4, 2017 |

Is there a big difference between the eccentric shaft in the renesis v the earlier 13Bs given its given a 9k redline and 10k fuel cutoff? Is it just tighter machining tolerances/better balances that allow it to be wrung out higher while stock? I've never really delved into the why of rotaries, but now that I have access to one, I'm kinda excited to learn stuff.

Also the Renesis doesnt have a perpherial exhaust port (side ports only) so the seals cant really be spat out, they are retained throughout the entire rotation. Looks like it also has a centre bearing - So there's the two factors limiting a 13B redline addressed right there. I believe there are rotor differences as well Edit : Yes htere are, the rotors are lighter. CAT INTERCEPTOR fucked around with this message at 09:24 on Feb 4, 2017 |

Metal gear, sounds like you've spent a long time trying to fix someone who only half wants to be fixed. Your future goals are incompatible and if you stick together to make a future one or both of you will have to compromise heavily and end up very unhappy. If she's not willing to earn any more money that's a problem. She's going to have financial trouble when you split but that's not your fault. I won't criticize the cheating, life's complicated.

I really don't know how you're best to handle this, however my normal approach to life is that with a lovely decision/situation, once you've thought about it, it's often better to be wrong in a hurry than drag it out in the hope of managing to reach "mediocre".

There are two people in a relationship and while there may be ups and down, you both have a responsibility to try to work with the other. If one of you is doing all the work, you aren't partners I tried to construct an AI analogy here, but it got messy.

Hell, I am and do. My daughter has had to deal with multiple instances of me sitting her down for an hour and going through the history of one band/artist/genre just so she really gets it. The cool part is that as she gets older, even though she protests at first, she appreciates it. Last year I made her listen to Pink Floyd The Wall from start to end and as we got to "goodbye cruel world" she was so involved in the story she actually gasped and went "OH NO!" and started to choke up. It was an amazing experience, and I'm not even a big Pink Floyd fan, but I appreciate what a landmark album that is. Best dad. Aside from the Die Antwoord thing, they're essentially as manufactured as the boybands you dislike just aimed at a different market. HAHA LOOK AT US WE'RE SOOOOOOO WEIRD AND ALTERNATIVE!! Too try hard. When are you getting to the Motown/soul sermons? Also funk, disco, house (and all million other subgenres of)?

Or crash at the next speedbump. So I woke in a panic last night, realising I've missed my MOT renewal. First thing this morning I ring the garage, can they fit me in?: don't know, the mechanics are late. Call later. Call later, yes they can fit me in if I get there in 15. Have to take my daughter (3), wife takes son to buy a present for a party he's attending. Daughter and I drop the car off and start walking to the train stain to get home. Wife rings, daughter is supposed to come to party too, she'll pick us up. So I end up at a kids party, but it's cool, meet new adults, they've got an animal show and tell thing too so I get to pet a skunk and a meerkat. 11:10 Phone rings, car passed, come pick it up. Cool, you guys close at 1 right? No, they're closing early today. I have 50 minutes. Cute 24 theme. Can't take wife's car, options are: walk to home, cycle to garage, ETA 12:00 Walk to train station, train, walk to garage. ETA 12:15 Walk to bus stop, bus, walk to garage, ETA 12:15. poo poo. I start walking/jogging. I stop jogging and start having breathing difficulties. Get home and get bike out. Massive urgent need to poop. 5 minutes later start cycling. ETA 12:00. Got there at 11:55, nearly dead. Receptionist is very sympathetic and finds it hilarious. Now I have to fit a full sized mountain bike in a fiat panda, thank God for quick release wheels as I've no tools. Panic when car starts rattling on the way give before I realise it's because I wedged a bike in there. Fun day.

Yay I finally got around to doing a clean lap of the Nordschleife with the Aztek. Unfortunately the Xbox DVR only captures 5 minutes at a time so I'd have to make multiple clips of the replay to get the whole thing but it's not really worth watching it all.

Just stripped down my boiler to replace the leaking O-ring. Turns out that it is a stupid assembly with a separate collar and thus 2 O-rings (I assume the valve assembly part was stolen off something else rather than being made to fit there intentionally) I have a box of assorted O-rings with over 20 different sizes in and none of them match exactly. I don't think anything in my selection box has ever been exactly the right size... cakesmith handyman posted:The body might look adequate but the frames rotten so you'll still fail inspection. Or crash at the next speedbump. You need to find a garage whom you can ring when getting there before closing is impossible and get them to just hide your keys somewhere so you can collect it after they close. I am very slightly concerned that one day their dogs will eat my keys before I arrive but it hasn't happened yet... Were you looking at Morris's the other week? my dad just bought 2. If you want a rusty body that needs welding and an engine that needs a rebuild (both separate items) I can probably get you a very good deal!

They also have a fighter jet on the roof, a bunch of army vehicles and I'm sure the owner drives a salamander. I also trust them with anything, they've never ripped me off in any way whatsoever. quote:Were you looking at Morris's the other week? my dad just bought 2.

I wonder if someone somewhere actually markets a selection box that includes all the sizes you actually need? I like the sound of them, but there is room for improvement if the dogs cant look after your car for you and save you from having to rush there for a pickup! He's already got a traveller. Its 2 minors he'd just added. I'd quite like to drive them but I seem to have an inability to work the clutch pedal properly in them and always make lots of horrible grinding noises. the pedal comes up from the floor rather than dropping down and I just can't handle it. I'm not sure if my feet are too big/legs too long or I just need lots of practise. fridge corn posted:I've put an offer in on a house Say goodbye to all those fun car projects you have been dreaming off for atleast the next 5 years (at least).
