1200 HP RX7 Dyno #2

[Bamchucknorris]

I've seen a 13b that makes 1077hp @ 40~ psi so I think this 20B can go even further!!

[UthinkUknowlol3715]

WOW! what a great engine! soooo crazy

[StonedAssassinNZL]

sounds like a piece of shit lawnmower

[madjimms]

@StonedAssassinNZL So do you. You make Cypress Hill sad with your shit comment.

[theflatlander]

Manoo62, lol at ur attempt to measure rotary displacement.

[Manoo62]

Three rotors with three chambers of 654cc each thats 9 x 654 = 5886cc plus a huge turbo....

[Sol79Invictus]

how many experts , just enjoy in sound you docs of filosofy

[mazda1988fc3s]

take that rednecks! who needs 8 cylinders

[greg18417]

3 rotors ='s nine cylinders

[cdsmith1990]

@greg18417 How do you come to that conclusion??

[firat123456789]

@cdsmith1990 i think hes talking about the 9 combustions that wud take place every revolution.... in a way he is right

[TEDDERAMA]

@firat123456789 Its only two pulses per revolution of the shaft. I know this is way late but I wanted to clarify for everyone who sees this...

So if measuring by compression's per rotation its only two 654cc chambers equaling 1308cc/79ci. 9 pulses is 4-5 revolutions... The rotors spin at 1/3 the speed of the eccentric shaft.

[firat123456789]

@TEDDERAMA 3 in ths case lool, but ye ur right my bad

[varkow]

@greg18417

LOL

3 rotors = 3 rotors, there is no possible comparison to any wankel engine.

there is no piston neither cylinder neither rod, so dont comment shit!

[tumzy187]

WOW I dont really think it has 1200hp however its got enough i reckon

[Brendon00000]

Incredible

[ssglopezvm]

I saw this car about 5-6 years ago... Belongs to Dennis from the Bronx,NY. Back then, I was impressed by the looks. I'm not sure about the 1200hp... I never saw this car do an 7 second 1/4 pass

[vinnie01]

auto gearbox?

[Parag0n]

Nice that thing is strapped down well to be making that sort of HP.

[20balvin]

u r stupid..this is call drag machine, keep the car as light as possible and loads of power at the same time...+they just havnt put the cover on yet...

[ShevardnadzeII]

you call this RX-7? whats left on it from rx-7? lol. but nice engine!!!! i would wona own one like that!!!!!!!

[liama32]

RPM'SS!!!!!

[rwdmonte]

who ever dumb ass with his hands over his ears was maybe shouldv'e went outside!!

well atleast you dont show his face PUSSY!!!!

[spartanic]

From the looks of it you probably have no idea how loud it is. Trust me when I say that you'll be covering your ears too. It actually starts to feel painful after a while.

[caos285]

@spartanic i remember when i was in the pit at a drag race and the alcohol cars came in i tried to not cover my ears but just when the idled i was like OW! but when they took off like right b4 my ears rung like crazy and had no choice to cover my ears

[spartanic]

Sorry but nobody has the ability to measure horsepower by just listening to the exhaust tone. Yet again we have ourselves an armchair expert.

[joshywebb]

Applause

[AudioGuise]

Yup, that sounds like 1172 RWHP.

[joshuwa88]

@spartanic haha. your right, power is in units of energy per time and sound is in pressure

[fstylezkrNNN]

@spartanic cant argue with that haha

[pljloves]

i wouldnt mess with that on track or highway i get smoke hella bad

[Lipsmoker]

No u wouldnt becouse it prob tops about 190-215 mph

[driftability]

Eccentric shaft not crankshaft.

[Cervan]

good god that turbo took forever to spool. but shit, the rest of the rpms were nonexistant after it did.

[dethman351]

nice sounds kwl

[GundamTriniArms]

well pplz thats a rx7 4 ya the best

[bklynrx7]

This is obviously a purpose built race car so streetability and a broad powerband arent a concern. I assure you this is no dyno queen there are 8 and 9 second rotaries at the local track all the time with similar setups. I would also like to inform you sir that I will NEVER NEED a V-8 for anything.

[simplybebop]

What I dont understand about dyno queens like this is they tune/build the cars all to hell and they have 1200 (like the car in the video) for the last 1500 rpms or so.

[NLRevZ]

That's because of the MASSIVE turbo(s) this thing has, when the revs are high, it will finally spool up and create an enormous boost to the engine, which makes it a heck of a lot more powerful..

[simplybebop]

i understand that . But it just seems very inefficient. I completely understand how big single cars work. Seems a nicely sized twin setup would work alot better in most cases .

[rv345]

that isn't a rotary

[DjMjInthemix]

The RX8 Is a roatary, not the Rx 7 =)

[logicalbomb]

RX stands for Rotary experiment, I am not even going to call you names for saying that. I have owned 2 1986 RX7's "ROTARY EXPERIMENT 7" 2nd generations and both had OMG 13B Rotarys! Now stop making stuff up.

[Slidingmy240sx]

WHOA!! Ricerage!

[mrdiesel96]

@DjMjInthemix every rx has a rotary, not just the rx8. r100- rx8 all rotary!

[Wastrol]

if it aint a rotor it aint a motor

[tasios77]

I don't even own a rotory yet, but hope to get an RX7 this summer. I love your comment, lol!

[tasios77]

Stupid reply system... my last post was in response to Wastrol's "if it aint a rotor it aint a motor" comment...

[mightyrocker]

goo rotaryyy!

[chohakkai36]

Screw what people say! That was fucking awsome!

[ddggffy]

very very nice...best 20b ive seen

[xped3]

cant u hear the slight pulsing when he gets off the gas

[MistaGreyDay]

wow

[kashrx7]

Of course it's a rotary (20b - 3-rotor), why is it so hard to believe?

[tpvalley]

Is it a twin or triple rotor?

does a twin rotor fire at the same intervals of rotation as a 6 cylinder 4 stroke, every 120 degrees.

I cant work out a triple rotor,? the same as a 9 cylinder 4 stroke? love the noise, sorry music!!

[yasafusa]

a 4-stroke piston engine requires four cycles per combustion.. so a four cylinder fires once per 360' rotation of the crank.. a rotor requires three rotations for a complete cycle, so a three rotor RX7 can perform this combustion every 360' rotation as well. (And due to it's design, the newer engine can put out 230HP in just a 1.3L) heck, I'd LOVE to see a 1.3L piston engine do this STOCK! So one can only imagine a bunch of tuning on a rotary!

[yasafusa]

found out it was most likely a

Holinger 6 sp sequential gearbox.. :P

[tpvalley]

4 stroke single fires every 720

twin every 360

4 every 180.

Each rotor fires with same regularity as a 6 cylinder 4 stroke I think...hold on errm...I'll get back to u on that! every 120 degrees?

sound good too!

[pukazero]

a 3 rotor fires 3 times for ever 360 of the eccentric shaft... but they they are not evenly spread out... two of the rotors fire closer together than the 3rd and that's why it kinda sounds like an inline 6...

[tpvalley]

wierd that they arent in perfect balance.

[pukazero]

yeah... i dunno why they don't even them out... but there must be a reason for it =P

[tpvalley]

I imagine its got something to do with using rotors from a twin rotor engine that can maybe only be connected 90 degrees apart or 180?

[bleedblack7]

@kashrx7 obviously its a 13b the engine tone is too low for a 20b

[LandonGear]

@bleedblack7 actually 20b's have a deeper throater tone than 13b's. go watch some 20b videos and some 13b videos... you will see

[Clunks1]

@kashrx7 Nice one looks like a blast :)

[HKStwinturboz]

wtf what kind of motor does it have? No way it's a rotary.

[yasafusa]

I'd put some money on it, being a rotary engine, but most likely a chevrolet trans.. :P

But it's very much so a rotary!

[smalleah]

its an FD ya digbat;

[yasafusa]

Um, yah, I know it's an FD model rx7, built from 1992 to 2002 in Japan, only to be released in the US from 1993 to 1999... FD = Chassis code... BUT for most really nasty *1,00HP plus cars, they'll but a built Chevrolet automatic tranmsission in it, due to them being able to withstand the abuse. That's all I was saying... ^^

[yasafusa]

oops, notice the placement of the comma, I intended placing *1,000 there.. :P

Now if we were talking about hondas, sure 100HP+ would be nasty... well it would be for a honda.. :P heheh, sorry bad joke. My built subaru has trouble keeping ahead of a honda S2000.. ^^ Those lil bastards are LIGHT!

[v8killa09]

WRONG the FD RX-7 was only available in the United States from 1993-1995

[yasafusa]

I see that, bummer, I confused the "last year Japan exported" with the last year Japan exported to the US. No wonder these are flipping pricey cars!
