The owner and tuner will be so much happier now that the youtubians have commented and pointed out their mistakes
LOve the sound of a rotary! Please come back ...
I second that....

The fuel systems on high hp engines running on methanol are pretty damn impressive, that's a lot of flow! :o
Vanilla protein shake intake for max gains!
That was more hp than i was expecting.
low torque though. which is expected.
+whatyareckon yea compared to the hp, still enough to get any car moving though and who could resist thos fireballs out the tailpipe :D
I love rotory engines is my dream to build some with 900hp and do 6sec in the quarter mile
Love mazdas.go team mazda.im fuking with that.
only engine thats sounds so good turbocharged.
You need to get out more
lol wot?
Only downside is the complete lack of low rpm power. 180hp @ 4200rpm. Still impressive numbers. When I was circuit racing in the early 90s no one turbocharged rotaries. The best 13Bs made 280-300hp. How things have changed.
Where did you use to race John? Series 4 RX7 were released in 1986. I would imagine by the early 90's a few saw regular track duties?
take a look at the dyno graphs of any 1000 horsepower 2JZ. you will see that engine barely make 200 horsepower before 5000 RPM
John Wilson the material used for apex seals have improved drastically allowing them to withstand such high boost.
Yes low rpm power but thats why these engines stock are recomended to be ran to 8k consistently by mazda themselves
Peripheral port? What's an extreme bridgport?
niiccee
Props to the artificial vanilla tube turbo intake xD
About 50 less if you use strawberry.
I’d be happy with turbo spool horsepower is just an addon😂
why not push it to 10000 rpm?
How low does a bridge port rotary like this idle? I can't imagine anything under 2000 rpm with how the dyno sheets looked
This one was around 1700rpm from memory.
Cool, Thanks for the response!
Worlds fastest 13B in PR = 1200HP!
RIP ears
Rip headphone users.. Holy fuck
Damn, I was expecting like 400-500hp.
I said 600 hp 400 torque. God damn 700hp?!!?
i never knew rotaries have such little torque
Perfect engine for light cars because you don't spin out. Great for track, not optimal for drag.
This engine is going into a drag orientated car, it's perfect because this engine's operating range is 6000 - 10,000rpm.
Fullboost Well that's weird... I know some people drag rotaries but never knew why. The origin of a rotary was to "cheat" in race car races due to the low displacement. Rotaries were initially made for racing though. Oh and also they make awesome water pumps lol
Fullboost Also doesn't honda engines also work in that rev range ? That also could work but the torque will be there.
You were expecting more from 1300cc?
I would rather use proper race fuel than methanol and risk melting an expensive engine as its so volatile
methanol burns cold as fuck especially when the afr is 3.8:1 lol
The majority of high powered rotary engines we see at the track run on methanol fuel.
@Jason Rochester. Exactly, that's one of the main reasons apart from octane that it produces so much power. Alcohol is like a refrigerant. Just dip your finger in methanol and feel the cold as it evaporates. It does the same thing to the intake charge making the air more dense.
Its not the temperature at which methanol burns or its natural cooling effect, its the detonation and pre-ignition properties of methanol that cause huge problems. Especially with rotaries, your engine can sound perfectly normal, making power, but at the same time doing damage to the engine and you have no idea until something fails.
+pure fire ... you have bad information about methanol. It is excellent for avoiding detonation and pre-ignition, it's the whole point of using it!
This thing sucks in some air 😂 and of course makes use of it’s compression effective to make a good enough amount of horsepower 😂
Torque wins races I guess rotarys don't win a lot
They have minimal weight on their side.
Justin Ballard what races does torque win lol hp wins races bud.... if it was torque then electric cars would b the only race cars
ask the mazda 787b :P
you've obviously commented on a subject you know nothing about. That makes you sound stupid when you do that.
Over 8 HP per cubic inch?
I wish that was my neighbors🥲
r otarys kick fucking ass i saw a big block Chevy lose its pink slip to a dat sun 210 thought it had a valve o rod fucked up untilI learned the rotary only has three or so moving parts
