Found this little interactive flash while surfing the internet. Pretty cool talks about the 16x and has some animations to go along with it. Not really any new information, but still cool to use.

There are also a few other interactive links along the side to play with.

 

I think this has been posted before, but I don't care...I love it.

 

Nice find - especially liked the vids on how to make a rotary engine.

 

^ yeah i enjoyed that too. Whole thing was cool and informative. Thanks!

this should be required viewing by all rotary owners, lol.

 

it's a shame that they dont go into a whole lot of detail about the "improved tq" from the DI and changes in dimensions. Can't wait to see what they expect from those... we can all guess, but they could always be higher or lower than anticipated. We should all complain to mazda and get them to replace all of our engines with the 16x under warranty when it comes out

 

lol please make a boost friendly engine this time no?

 

if its going to the exactly the same size... it would work pretty well going into all old models... if the car is ugly, 16x-fd3s

 

Indeed it has. Simply search 16x.

 

can't wait

 

It looks like I may have to write another tech article.

 

doesn't it have to do with the larger internal rotor housing shape, allowing the rotor to become larger, allowing for larger eccentric shaft lobes (more eccentricity), which results in a longer torque arm?...or am I way off?

This allows you to play around with different rotor parameters, and shows an illustration of the torque.

your tech articles are always a nice read... but what I was going for is specific numbers they get into an actual production car with it. I'm sure we can figure out a decently accurate range to anticipate, but what matters is what mazda actually releases.

 

They aren't going to show something like that on an engine that is still 4-5 years out. There'd be no point to it. They are still revising it. All we can do is wait and see. This assumes of course that it will actually become a reality. The current global economics right now may change things.

There are a few things that I can talk about that would seem to make sense as to the reasons given by Mazda for the gains associated with the changes. To describe those I can't just sit down and type out a thread like I used to. I'll have to prewrite it since it'll take some calculations. I'll work on it and we'll open up a discussion session based purely on objective speculation and hopefully in the future we'll all be able to see how accurate our assumptions were. It actually sounds like fun.

 

do it RG

i like reading your articles, rg. i don't necessarily believe everything you say in them, but who cares, they're interesting to read regardless. please do write up a tech article, i haven't had any interesting things to read in a couple weeks

 

A question for RG or anyone else in the know:

What's the current weight of a fully dressed Renesis 13B? With a switch to alumninum side housings, how much lighter could this new engine be over the current version?

 

I love how a lot of people talk about swapping in a 16X like you're swapping an LS6 into an LS1 Camaro, or an SR20DET into a 240sx. The wiring is going to be completely different, and likely so will the oil pan, engine mounts, etc...

 

Just to give you an idea, a full swap to Racing Beat's aluminum side and intermediate housings on a 13B from the stock cast iron housings will shave somwhere around 40 lbs off of the block itself. If the new engine had a full composite intake manifold further weight could be saved.

 

Thanks for the info. What does the current Renesis 13B weigh?

 

From the sticky in the tech garage

 

^ Excellent. Thanks.

 

I don't think people expect this engine to be plug-n-play, however, as the external dimensions are the same as the current Renesis, it should fit into our cars with minor modifications. Plus, the factory ECU and wiring harnesses could be had for cheap from wrecked cars.

I personally will want to buy a new RX-? with the 16X Renesis (rather than do a swap) as it appears that Mazda will work to reduce the curb weights of their upcoming cars. Hopefully the engine will be offered in 2 seater and 2+2 seater configurations.

 

Agreed. I'll probably find a way to keep the 8, and if I can't, I'll trade her in for the new Rexy.

 

Mazda has said the 16x is about 20% lighter.

 

Can't wait! Thanks
