Scoot FD

[XzifT]

I was looking around the net and I found two videos of the Scoot RX-7. From what i've read, it's got 500 HP NA. Its twin Turbo and a 4 rotor.. Crazy.

Option 2 Review - 1 minute 13 seconds
Things at work

 

[CDailey]

It sounds like a Formula One car.

Also, what was that glowing in the Option video?

 

[XzifT]

Tell you the truth, I havent the slightest clue.

 

[-Fred-]

1450 hp? A bit optimistic, perhaps?

 

[XzifT]

I dont know..Doesnt the Lemans 787B use a 4 rotor..?

 

[-Fred-]

It did, but this isn't an engine similar to it. I believe it was built using two 13Bs put together, whereas the 787B's was a single motor.

I think that glowing thing is called a catalyst converter. All the heat is leaving the engine and being pushed through the exhaust, in which case it gets hot. Since there's a buildup at the cat. it heats up, it's for air polution regulation.

read about it here.

I would like to see that car in action, all i've ever seen it do, is rev it's damn cool sounding engine. BTW I like video #2, it makes a nice beat, I want a 4 rotor engine, with twin turbos.

I like rotary engines except for the fact that there's a lot of combustion going on in there. Since there's so much combustion I don't doubt that if it blows, it will take many things with it. I love the fact that they have very few moving parts.

A two-rotor rotary engine has three main moving parts: the two rotors and the output shaft. Even the simplest four-cylinder piston engine has at least 40 moving parts, including pistons, connecting rods, camshaft, valves, valve springs, rockers, timing belt, timing gears and crankshaft.

It sounds like one of those race-style go-karts. I like it.

 

[Thio]

So this FD has 500hp with no turbos and 1,450hp with two turbos?

Sweet

 

[XenoN]

Uh how much ? 1450? If this is true I think thats one of the sickest things ever

tuned 502big block
estamated HP with turbos 2000HP @ 5000RPM

(i dont actually have a 502)

 

[Boost Lee]

A 502 isn't 2.6 liters of displacement.

eh. duh??

was this a joke?

Was this?

A HUGE motor making big horsepower = old news.

A TINY motor making big horsepower = cutting edge.

 

[Jay]

yes!, sort of

without going into how everything works, 4 stroke piston engines displacment cant really be compared to a rotorys displacment.

its actually better to compare a 2 stroke V6(mainly in marine) to a twin rotor rotary
even then a rotory will still comeout on top in most cases


BTW 1450hp out of a 2.6(quad rotor) is damn good but not new in terms of capacity vs HP
RB26 with about the same HP (has been done, more than once, with still keeping it at 2.6)

Additionally, the 787B put out 700HP with turbos included. These guys are planning on doubling that.

 

[Boost Lee]

The 787b motor was limited by rules to around 700hp.

VIPERGTSR01 - You strayed so far off topic I don't know where to begin. I'll start with the RB26DETT.

A good %98 of the big power RB's I see are stroked or the bottom end is built, coincidence? Maybe. The RB26 is fairly new as far as motors go, so it is news. It also has more than 5 moving parts.

My point was, a big block putting down big numbers is not news. Why you would post the stats of a 502 in a thread about a Rotary is beyond me. That's about the same as someone posting a picture of a guy in a thread about women.

Here are some things to consider. The piston engine has had 100+ years to evolve. How long has the Rotary had? *Hint - mid 50's

 

[zoxxy]

You can actually attach that engine too the Empire State Buildning and it will STILL do 0-60 in under 5 sec .

i agree most RB's do have the bottom end built, im not debating any of that

WHAT i WAS originally getting at, is i find it funny how they can make such a precise HP estimate on a engine they havent built yet, so if i had a 502 i could estimate i could have 2000HP when i put turbos on it. it was suppose to be sort of a sarcastic joke, i wasnt having ago at rotors, i was sort of having a go at the people that wrote the estimate

 

[Boost Lee]

My mistake man. I'm a little defensive about the triangles.

 

[Jay]

no probs

980rwhp through an automatic, no nitrous. Stock shortblock.

Want me to post a link of the Scoot FD in action?

 

[XzifT]

Post it now!

 

[AREITU]

Urm...someone want to host it? I don't have the origional link on Option anymore. It's not too big.

What does a 2jzgte have to do with an RB?

The Option Two Scoot videos were posted in the Rx-7 Club thread a long time ago.

Do you have aim, msn, yahoo, or anything like that? Maybe I can find some hosting for ya. I can't have the file emailed, cause my inbox's are getting full.

If ya have any of those, this is my info...

please, if your not AREITU, don't bug me. don't want to sound mean, but every time I post up this information, I get 60 people I don't know IMing me asking me for things.

 

[GetFresh.]

Lots of misinformation regarding rotary engines in this thread.
I don't want to go over everyones posts and nitpick all the little things, but a few things that stuck out in my mind are as follows:

This scoot engine is NOT two 13b's mated together. It IS actually very similar to the 787B lemans winning R26B engine. Not many custom parts need made to create this engine - the eccentric shaft (similar to a crank for all you piston engine fans) and the manifolds are really all that's custom. Jeff Bruce down under makes custom shafts, I think he even made this one. He makes the shafts for Abel Ibarras 6 second, 1400 hp 20B (3rotor) engine.

The 787B engine was normally aspired, NO turbochargers.
It MAKES (the engine still hasn't been rebuilt since the race!) 700 hp @ 9000 rpm and 620 ft-lbs of torque @ 6500 rpm. it also uses variable length intake runners, which lengthen at lower RPMS to provide a broader powerband at the expense of slightly lower overall HP number.

1450 hp with turbochargers on a 4rotor would not be too suprising. However, not many people have made 4rotor engines, therefore, anyone making big power is great and even greater when with this engine.

Also, Yes Skyline engines can make insane power like this. No one is going to debate that. However, just how many skyline engines still using a 2.6L displacement make 1450 whp as someone claimed? I would be very suprised to find a few, if even one. I know 3.0-3.2L skyline engines have done it.
Very impressive engines however! Best in the world perhaps.

This better not turn into one of those immature "dyno queen" hp flaming threads. "This supra makes XXX hp, this corvette makes XXX hp"

As VIPERGTSR01 stated, it's very unrealistic to compare rotary engine displacement to piston engine displacement. Many racing sanctioning bodies simply doulbe the rotary engines displacement (which is actually it's proper, theoretical displacement) to make it comparable to piston engines. (ie: a 1.3L rotary competes against 2.6L piston engines). Very lose comparison of course, but it's hard to do better.

 

[87GrandNational]

Horsepower sells..........Torque wins races.

and i thought the rotary motors were 1.3L of displacment


wouldnt that be around 5.2L of displacement if its a 4 rotor?

(((Correct me if im wrong i know very little of rotary.)))

Arent the Apex seals time bombs in those cars too?

Iv seen many of RX7 blow apex seals with only a couple of mods.

Ill end up putting a Twin Turbo GN motor in an RX7 sometime.

 

[Boost Lee]

The Apex seals are not time bombs, nor is the Rotary engine. The fact is, it doesn't matter if you have a piston or rotary motor, if the owner/tuner is negligent the outcome will be the same.

Rotarys are however less forgiving to detonation. It definitely requires a higher level of skill to tune a rotary. Most people don't have that skill or the proper knowledge on how to upgrade, and things end with premature engine failure.
