Anniversary Racing Factory in Japan has long been specialized in Naturally Aspirated rotary tuning in Japan.

Their NA Dyno page has long been the best place to find high end NA rotary dynos (notoriously hard to find) and they have recently updated their page.

Top dog is now 352rwhp putting down an incredible 214ftlbs torque from its great low rpm power peaking around 8,7000rpm.

 

Is PS horsepower or a metric measure like Pascals? It has Kgm under it on the top of the graph and that would be kilogram/meters, I think

So that is torque or it is saying, as in empirical graphs, that PS =Hp and the same side represents torque in kilogram/meters? I think it might be.

I guess I'm asking if it's an empirical graph or a metric graph because maybe a conversion is necessary.

 

IIRC, PS is the metric horsepower measurement (over imperial horsepower).
Quite close in amount (wattage), but a slight difference.

I thought they posted a 351ps dyno like 12-15 years ago.

Okay I rmemebr 351, maybe it was 352 after all? Anyway, old video. Very old.


Sounds like he might be saying "three hundred fifty two" at the end, so... ok.

Could have sworn it was 351.

Edit: It's the same damn dyno sheet, just legible because it's a screenshot and not a highly compressed low-res WMV of an encoded analog video of a computer screen

I wish Taka would put the Swirl Silencer video up. That was incredible.

 

Also:



The kind of cool **** A-RF used to put on their website for download.

 

My bad on the imperial/empirical thing. I mispelled it and that is what Google gave me so, I ran with it.

 

Newsflash! ARF updated their dyno page 5 years ago.

Hmmn, looks like I just didn't remember how badass ARF was and thought they had lower #s before.

Thanks for posting those vids!

 

I wish we could see their exhaust setup. This is exactly how I want my car to sound eventually...

 

The Shuto Expressway traverses the Megalopolis of Tokyo over, under, through and around Tokyo Bay. https://en.wikipedia.org/wiki/Shuto_...#Street_racing

As sections form loops (circuits) street racers began informal record attempts.

The Bayshore Route known as "Wangan" is the most famous in the Tokyo area.https://en.wikipedia.org/wiki/Bayshore_Route

On the Aqualine (Bayshore Route) there are under sea tunnels as well as the bridges.

In the Metropolitan sections there are tunnels through the city structures and walls and tunnels are used in other places as sound control as well.

In the early days ('80s) the racing was fairly well socially accepted as they raced at night and the roads were not near capacity yet. The Japanese tuning scene really began at this point.

The situation came to a head in the early '90s with the popularity of the Shuto Kousoku Trial movies. https://en.wikipedia.org/wiki/Megalo...pressway_Trial The first of the series was filmed on scene and at speed and became banned in Japan.

Keiichi Tsuchiya came on board for the sequels and they spun the movies into an anti-street racing message and filmed on location with sped up footage.

I believe they are toll roads that you pay to get on, but can stay on without additional toll. There are large rest areas in the loop that are popular meeting places for the auto enthusiasts.

There is a whole car culture built up on Wangan and a different culture for the lower speed intra-city surface street racing down in Kyoto with the Kanjo racers.

The aesthetic of Wangan really is defined by the tunnels and the very high speeds (150-200mph peak).

 

I think most of it is possible over there at night because of their mindset. From everything I have seen they understand the importance of not tearing things up or leaving trash behind and are generally very respectful so as to not cause a problem that will get spots shut down. That is what I respect and admire the most about their car culture and I believe it is why they can strike a balance with civilians and police to keep everyone happy and safe. In the US there are always a few people who do a big smokey burnout or constantly two-step or bounce of the rev limiter causing a bunch of noise and getting places shut down.

 

Wouldn't YOU want to drive through a bunch of tunnels if you had a great naturally aspirated rotary at your disposal?

There's a few tunnels through Columbus and especially Cincinnati. Went through Cincy a couple times last winter, first with a truck but the second time with my Volvo. I wished both times I had the RX-7 so I could hear the echo. All I could do was work the turbo on the Volvo and make lame-*** bypass valve noises

(some day I'll finally block off that bypass valve... or just get another car or something)

 

Just to recap...

What 80-100mph in a turbo car in the US is like:


What walking speed with a N/A rotary in Japan is like:


What makes an awesomer video?

 

mustangs.
