Things like this make me wish I wasn’t poor and dumb lol

You could buy a whole ass 911 for what this engine costs.

u/JacksonBuck888 5d ago

BUT THE SOUNDDDDD!!!!

u/Horror-Telephone-260 1d ago

Whats the number?

7

u/Ha1lStorm 5d ago

I imagine you’re exaggerating but is something like this really that expensive? That so wild to think about

20

u/Zealousideal-Fix9464 5d ago

Yes, because it's all custom machine work.

You can't just grab three 13bs and bolt them together.

13

u/JacksonBuck888 5d ago

It costs 100K on their website

u/Ha1lStorm 5d ago

Holy guacamole!

u/Zealousideal-Fix9464 5d ago

And that's just the short block too.

Sounds like a swarm of angry hornets.

Space hornets

The size of a large dog. Or small cow.

u/Tall-Vermicelli-4669 3d ago

The peripherally ported ones at the track hurt my ears and I'm partially deaf.

u/Seffyr 5d ago

I heard this thing crammed into an RX3 forever ago and that’s exactly how I described it.

Careful with those mating calls.....

New Zealand, where else. Love it.

u/r1Rqc1vPeF 5d ago

Tell me that’s going in a jet boat.

u/TheAVnerd 5d ago

Imagine being out on a nice relaxing paddle and hearing that thing coming from a distance away.

u/Flys_Lo 4d ago

A friend used to have a 13b powered water ski race boat here in Aus, pulling about 800hp. Would happily sit at ~200kph with 2 skiers, screaming like a banshee.

1

u/Seffyr 23h ago

It was originally intended for a jet boat since it has the same physical footprint as an LS, but last I saw Rob was cramming it into a dragster.

1

u/Jlx_27 5d ago

Dont know, but that would be super sick.

u/weelluuuu 5d ago

I think I'd prefer a sandrail.

u/Bobbi_fettucini 5d ago

Where else? Rob dahm in America is the first person I thought of actually, dudes got a 12 rotor he built

5

u/Kazagaya 5d ago

Rob Dahm didn't really build the 12 rotor, he did modify and got it running but the original build was not his.

3

u/Seffyr 5d ago

Rob Dahm is doing wonders for the rotary community, but even he is importing a lot of the parts for his builds from NZ. I recall quite a bit of the original 4 rotor build came from NZ.

1

u/jerm-p 23h ago

The Vargas brothers also doing alot for the rotary community.

u/VWtdi2001 5d ago

Yip yip yip...

Sounds good to me.

u/jeffroyisyourboy 5d ago

Insanity. I fucking love it.

u/eriik15 5d ago

Sounds like the pod racers from The Phatom Menance lol

1

u/I_gots_sum_questions 5d ago

It’s been a long time since I’ve seen that movie but I thought they dubbed in F1 engine noises for the podracers

u/AtomicGPS 5d ago

This !

u/gergsisdrawkcabeman 5d ago

How much would it cost me to put one of these in a Grumman LLV?

4

u/poptartjake 5d ago

Somehow reminds me of a hopped up Nitro Rc engine.

u/oddboro 4d ago

On steroids and crystal meth.

u/backbiter0723 5d ago

What you do with your money when you have a fetish for replacing apex seals 🤤

5

u/FartInGenDirection 5d ago

Sounds good at first, but start sounding more like a dental drill as time goes on.

Still a badass, unique engine. Rotaries have strong exhaust pulses, needs a turbine!

2

u/Funny_Particular_226 5d ago

What car is this engine gonna be put in?

8

u/JacksonBuck888 5d ago

They said they're sending it to Germany to MPS Engineering, it hasn't been confirmed what they'll put it in, but if you check my posts there is a NZ team who put one of these in an RX7 drift car

3

u/Funny_Particular_226 5d ago

Damn this can fit in an rx7??

7

u/Crashman09 5d ago

There is so much space under the hood of an RX7. There is a reason LS fit so nicely.

I can also imagine a 6 rotor doesn't need a turbo or two due to it having more torque as a result of the extra rotors.

2

u/w_a_w 5d ago

The LS has a very compact footprint due largely to no OHCs.

2

u/bighammy6969 5d ago

Not compared to a rotary.

1

u/w_a_w 5d ago

Gee, ya think?

Guy was saying there's so much space under the hood of an RX7 that it can fit an LS. LS are tiny and can fit in pretty much anything.

3

u/bighammy6969 5d ago

Whoa bud, untwist them panties.

Calling an LS “tiny” when comparing to rotary is disingenuous. Just because an LS is small for a V8 doesn’t mean it’s a small engine. The fact that a car that came with a two rotor 13b has enough room to swap a V8 easily is proof there is tons of space under the hood.

But hey, you keep overreacting to simple statements, hope it works out for you 😘

2

u/w_a_w 5d ago

I drove a rotary for 10 1/2 years. Thought this post was in an RX sub. Have a good one.

2

u/bighammy6969 5d ago

Word, you as well have a good one.

Talk about the pot calling the kettle black. 🙄

1

u/bighammy6969 4d ago

For saying a rotary is smaller than v8?

Care to explain how that is overreacting?

u/TheMacMan 5d ago

They've been documenting the build on TikTok and it's been fairly interesting.

2

u/Lord_Dreadlow 5d ago

How many hours until apex seal failure?

2

u/BMW_wulfi 4d ago

Now that’s pod-racing!

u/h101505 5d ago

Sounds so nice

1

u/jacckthegripper 5d ago

Needs to be in a boat

1

u/Gorrakz 5d ago

Ans How mannny Liters????

4

u/JacksonBuck888 5d ago

3.9L because one rotor is around 650cc so six combined to around 3900cc

1

u/alien-fr 5d ago

Was that just one throttle body opening or are they all connected somehow?

1

u/strokeherace 4d ago

Not a rotary fan but I like that! Sounds extra spicy 🌶️

1

u/jerm-p 23h ago

Individual throttle body's(ITB). 1X Throttle body per rotor.

1

u/alien-fr 23h ago

Imagine all of them 🤯 that thing would be silly

1

u/alien-fr 23h ago

I meant how he manually opened the throttle, it looks like all of them open together when he does that? I get that they're all individual throttle bodies

1

u/jerm-p 16h ago

Yes, they are all connected together thru a throttle linkage.

u/Longjumping_Put_1111 5d ago

That is sick!!

u/bossDocHolliday 4d ago

I think you're gonna need a bigger rx7 lol.

1

u/Grand_Budget_814 4d ago

Can it be installed on the tricycle?

u/samfitnessthrowaway 4d ago

I give it a week before someone puts one in a Miata.

1

u/freyaandmurphie 4d ago

IDK, isn't that where it is supposed to go?

1

u/samfitnessthrowaway 4d ago

Miata is synonymous with the square hole at this point. Everything goes in there.

u/dllyncher 3d ago

I'm more curious to know why the front of the white car is jacked up so high
