Well, its a RX-7 website, not a felix wankel nutrider website

Its been made abundantly clear that v8 swaps do nothing to hurt the car except the egos of some people who clutch to the rotary engine for some odd reason, see v8s as the 'enemy' which is out to be 'beaten' (go go good advertising making their product being the rebellious small displacement freedom fighters against the oppression of the v8 overlords ) and that what people here love is the CAR, not the engine.

The facts are the facts, and theyve been said so much I wont bother repeating. Do whatcha like but being a bigot over an ENGINE GEOMETRY is absolutely absurd. Lets go invite some scoobie fanboys to tell us off about "two wheel drive" or get a VTEC fanatic to chew us all out! Hey, why not drag in Stephen Hawking and rip him a new ******* about quantum physics and handicap ramps!

 

i've never seen a video of a real FC vs FD with around the same HP (and both having rotary engines)

anybody have any videos they'd like to share?

 

mmmmmm.... V8 engines. yummy.


-theANTIrotor

 

why people like "theantirotor" insist on joining a site dedicated to rotary engines is beyond me.

 

Because this is a site dedicated to RX7s and not rotary engines?

 

no there is a section dedicated to the rx7 and pistons other wise it is for rotaries.

 

No. This is RX7CLUB.com, not ROTARYCLUB.com

We all love the RX-7, just some of us have different tastes in powerplants.

 

 

Exactly, rx7club.com, let me spell that out for people that don't know what that means. Rotary Experiment 7 The site is not called px7club.com


Pure ignorance...

 

Please, put this myth to a rest by showing us IN PRINT from MAZDA that RX stands for Rotary Experimental. Until you can do that, it is a myth.

I guess the Acura RSX is Rotary Super Experimental, eh?

 

are you talking? i can't hear it over the exhaust note of my v8 rx-7.

 

Hasnt it already been demonstrated REPEATEDLY that what makes the RX-7 good is the chassis?

Funny how no matter what engine you put in it, it kicks ***. Too bad Kukris CARBURATED 350 with a set of coilovers and 225f/245r spanked a STi and a Z06 on an autocross and ran a low 12 lifting off before the traps.

The huge engine bay, well set up chassis, the stiffness of it and the ability for it to handle, even when it uses a less than optimal suspension setup (like the FC) is a real testament to Mazda's ability to make a chassis. However the rotary engines were the ultimate handicap. Id argue they made the RX-7 chassis so good to make up for the lack of power and torque.

Nevermind its a ******* fact that rotaries have a higher BSFC, are thermodynamically inefficient and not exacty reliable when you use boost. Theyre also 2.6 liter engines per the standard measurement of TWO CRANK REVOLUTIONS, and if they crap out a seal you have to remove the whole damn enigne and get expensilve rebuilds. And they run hot. And they necessitate oil coolrs. And instead of changing heads or cams you have to port the side housings and/or peripherial housings.

You can rebuild a v8 with it in the car, if and when you actually need to do it. Plus, you can increase displacement without having to use a 20B - which *ba da da daaaaa* is bigger and heavier than a 13B!

BTW, I heard one person argue that because a piston engines displacement is measured per two crank revolutions, they should all be half of what they're usually called. So, if a rotary is a 1.3, and a LS1 is really a 2.85 liter... well well, look how the piston engine is more efficient. 1.3 to 2.85, or 2.6 to 5.7 (it has to be both ways...) its a joke.

When Mazda works on the BSFC and BMEP inadequatsies of the Rotary, probaly via ceramic coating and direct injection into the combustion chambers if they ever try that, Id think twice about using a rotary. Oh, and I'd like a little more displacement out of it, so its actually competitive vs the 'boinger' alternatives out there. The torqueless revmachine title goes to the Honda S2K, and the new "SBC" of the import world is that VQ35DE. Oh, wait, the S2Ks engine has more torque AND more power, and better fuel consumption... and its more reliable and it has less displacement than the RX-8.

 

And it sounds better

Edit: P.S. Rt click save as please!

 

All of this is just your point of view. If you think the rotary can't compete with the boinger you must not get out much. I think the chassis is a great part about the rx7 but what really counts is the power plant that pushes it. I think a v8 is a mindless way to get high hp. Any moron can get a v8 to have lots of power with that much displacement but for me it's more challenging getting smaller displacement engine's quicker and much more rewarding in my opinion. So what if most people suck at tuning cars and can't keep their rotary from popping a seal? If you do it right it will last just as long as a high hp piston engine. All of this of course is just my opinion but I still think if the rx7 were intended for a piston motor they would have made a v8 option.


jeez that was funny

 

A V8 and a Rotary at the same HP, there is no way the rotary will last as long, the larger engine is just plain under less stress. This even goes for smaller displacment piston engines. Take a 400hp honda and a 400hp SBC, the SBC will last longer as the engine is not working near as hard or turning near the RPM. Add to the fact the SBC will have a much more usable powerband and will lend itself to daily driving much more easily.


I have done both, the big turbo rotary and the V8. Most rotary guys who bash on the V8's aren't speaking from any sort of expierience. I bet I have more seat time than you in a rotary powered vehicle and know more about rotary tuning/building than you.

I am not saying I would never had another rotary powered car, but after doing my swap it definatly did not detriment the car in any way.

You say if the rx7 was intended to have a piston engine they would have made it an option? I then say that if a TII was meant to have 400+rwhp they would have made it an option.

 

That must be the dumbest thing I've ever heard, but it is quite common to hear from the die hard rotards, since it's about the only reason to chose rotary over a v8 You must challenge yourself getting power out of your engine instead of say challenging other drivers at lets say Strip or Auto x or road course. You have fun challenging your engine, but I'll be challenging a Viper at the strip and modded STI/Elise/Miata/Z06/Evo/etc at the auto x instead.

Oh and by the way you're right. If rx7 were intended to not break and be a real fun sports car, they would've definetely went with the v8 option.

 

Mazda wanted to set itself apart by using a rotary engine. However, as we all know, the output of a rotary is not quite as high as that to a comparable piston engine. It IS small and light, however. Even when under boost a rotary engine is less efficient due to thermodynamic concerns, and the fact that they seem to need more fuel to make the same poewr.

So, guess what they did? They made a KICK *** CHASSIS. As it has been demonstrated repeatedly, no matter what engine you put in it, it kicks ***. Arguably the S2Ks engine is sucky, because the powerband is peaky, and you have to shift like mad to get anything out of it - and off the line performance is extremely difficult and desructive to the drivetrain to eek out of it. You have to drop the clutch perfectly at high rpms in 1st gear, and then shift into second quickly and perfectly. Torquey engines arent so damn finnicky. But hey, honda made a great cahssis for the S2K to make up for it.

Mindless because its a wiser choice? Its more thermodynamically and fuel efficient, is that mindless? Is choosing something wtih cheaper parts mindless? Its common sense. Someone whose point is to get performance without strings attached and without spending a lot of money is not 'mindless'. Buying into some 'us vs them' mentality against the large displacement overlords is somewhat mindless to me. Oh, and smaller engines arent 'quicker' by default. How "revvy" a engine is depends on where its torque curve is and the weight of the rotation assembly and the flywheel, especially. A balanced/blueprinted 'revvy' v8 could bounce off its rev limiter with the best of the rotaries. But well then again so could any enigine *sigh*.

There isn't mindlessness at play here among the v8 guys. Its more like "hey, this is a better, cheaper, more reliable choice, with much more potential!" Id accuse someone of keeping the stock engine of being mindless, or someone who buys into the small displacement vs "the v8s, lets go get 'em" someone whose mindless and has bought into some rather genius marketing strategy. That is, a strategy making v8s look unsophisticaed, crude, and the people who use v8s as unsophisticated mulletheads, and you, as a sophisticated consumer, should buy a 'higher tech, sophisticated' engine with 'smaller displacement', and engage in a battle of 'technology' vs 'dumb displacement'.

Now, as far as COMPETETIVE, yeah, it can be competetive, depending on the rules of the race. But in the end piston engines are more efficient, reliable, and modifyable, PERIOD. Something more subjective such as is a v8 a good geometry is difficult to prove in a black or white sense, but as far as anecdotal evidence and observation goes, they're very good layouts. Lots of displacmeent in a efficent use of shape. Its also fairly smooth running. But ultimately, youre comparing a boosted small-displacement thermally and BSFC inefficient engine to a more efficient piston engine with more displacement that can use the same power adders a rotary does - and can arguably do it for cheaper, and its proven to be more reliable.

So, sorry. Analyze your own motives before you call someone else mindless or lame, please.

 

Just tell you friends you couldn't get a trophy at the auto x, because you were too busy challenging your engine, they'll understand.

 

 

FD s FC **Video** Both ... 08-10-05 09:51 AM your an idiot

Its you're, as in you are, an idiot.

your
adj. The possessive form of you.

you're

Contraction of you are.

YOU, are an idiot. Sorry.

 

Err, you are using the wrong baseline for efficiency (fuel consumption?). Engine efficiency is measured by displacement & in some cases, by the weight of the block (not gas mileage, especially Vs a V8 which is no fuel miser by anyone's measure).

The new RX-8 N/A engine puts down roughly 185 Hp/Liter. I don't know of any N/A production powerplant that is that efficient. The Honda S2000 comes in at 125Hp/liter (impressive, but not anywhere near the rotary).

I'll have to look up the weight & do a V8 comparo, but I believe its going to win that metric as well.

See ya,

Um what are you talking about? There are plenty of rotary powered rx7's dominating the auto x course. That’s the sort of mindlessness I'm talking about right there. I don't have to prove anything; you guys do it for me. I also heard someone say something about you challenge your engine while I challenge a viper blah blah blah. Well last auto x I went too the third gen ROTARY powered rx7’s where spankin' the vipers left and right.



Some people would rather get to know their engine inside and out and take pride in modifying their car and making it the best it can possibly be rather than just throwing some old v8 in there and racing it. I guess thats the differance between the two types of people. I guess half the challenge to me is getting my car fast knowing it will not lose to the other v8's on the streets and then after the car is perfect I will race it however to the common person it's not about what you have under the hood and how long it took you to figure out ever detail on that car etc.... all that maters is dropping the v8 in the car and racing, witch is fine it's just definatley not the way I am with my cars.



I'm having trouble with this argument of more efficiency??? I just don't understand if your buying a RACE car to RACE it then who the hell is thinking about efficiency anyways? Reliable? I don't know man most of the top dragsters out there only get a certain amount of passes on their motor no matter what engine it is. Now if you mean reliable as far as an every day driver then there was nothing more reliable than my tII. The car had been through 3 different people until it got to me all on the jspec engine the first guy put in it. Each guy upgraded it and upgraded it all the wrong ways with reliability nowhere in mind and that thing lasted forever! The only reason I'm rebuilding right now is because I wanted to make sure the thing would last to California if I went to seven stock. I don't think I could say the same for any wrongly modified piston engine.

 

yeah well most people that swap v8s engines know their engine inside and out, cuz hey v8 can be modified too. One more thing. Who cares what hp does it get per liter, that's the stupidest thing I keep hearing from rotards and honduh lovers. What matters is how fast the car is in a straight line and around the track.

 

typical rotard??i hate that statement lol what the hell? its funny how 350 hp rotaries always whoop on 500hp v8's well atleast donw here..lol the only reason piston engines are more reliable is because rotary engines do not have aftermarket internals liek a piston motor. yes there are ceramic seals but whats the the factory seal hold better there are no aftermarket housing or rotors...yea and port a hoel into the side of your block and let see who runs longer lol v8 growl lol PRA PRA PRA!11
