I never thought about that. Why can't an RX-8 get lunch? What the hell else does it have to do??

You're a friggin genius.

If you could take 600 pounds off the RX-8 (a Renesis MX-5), you'd probably be doing the quarter in mid 13s. That would be impressive for an N/A rotary, and you'd still have a daily driver.

If you took off your pants, you could probably run faster, but why would you want to?

This car isn't a tiny roadster -- why does everyone want to make it that way? You guys should just go buy S2000's -- I think you'd be happy.

Horsepower doesn't matter, torque does. Should he have asked"how do I get more of that seat of your pants acceleration feel out of my RX8?" He could add every bolt on performance part available and it may "feel" faster to him. Thats all that matters. Just stay away from the dyno test and you will be fine. All I've done is the Mazdaspeed exaust. It sounds nice and the car "seems" to pull better. Thats fine with me.

I don't WANT to make it a tiny roadster. All I'm doing is illustrating what it would take to yield a "respectfully fast" N/A Renesis as-is without the aid of forced induction. It would need a huge diet with no carbs and only protein.

saturn

First off, I hope you were joking about that "seat of your pants" remark because someone asked that question almost verbatim and everyone flamed him too.

Secondly, torque is just a function of horsepower and the rotational speed of the engine. They are essentially the same. Given one, you can determine the other for a given rpm. Saying that horsepower doesn't matter but torque does, doesn't make any sense.

Oh my God I actually think you are serious! How mind boggling is that? It's not a loaded question. Although I suspect some of the people in this thread are. I'm just going to be blunt, a lot of you guys are being ******** who are taking the title a little too literally. How about this, "Why don't modifications to the engine in it's naturally aspirated form not give as much power as the same mods did percentage wise to the older non turbo rotaries?" Is that better? Is that more clear? Did he not at least convey what he was asking even if the title was slightly misleading to maybe one or two people who lacked the brain capacity to figure it out? Jesus F'kin Christ you guys are dicks sometimes. OK that was a bit off. Most of the time. At least when it comes to new people. That's why the rotary has a bad reputation among other forums out there. It's the wonderful warm welcome that many new people get for asking innocent questions. He wasn't a dick to anyone here with the original post so stop being one back.

This thread is EXTREMELY close to being closed and a few people taken along with it.



























































...same to you!

And torque doesn't matter when you have 'gearing'.

dmp

go away, newb!!

:D

^^ lmao

i know you didnt mean it but just to make the point- the engine would make the same horsepower no matter what the car weighted.

Actually, I think the slapping might slow you down.
The drag would certainly bring me to a complete halt.

saturn

Who said anything about running naked sicko?

toxin440

man ive never done a full out run naked, but it wouldnt be great... ***** slapping back and forth at high velocity = PAIN.

heres my view on it

Horsepower is how fast you can hit the wall... Torque is how far you take it with you

BaronVonBigmeat

You can't boost factory power levels as much as other cars because:

* With factory turbo cars, you can crank up the boost

* With previous rotaries, Mazda left more HP on the table so to speak. This is probably because of the immensely powerful finite elemental analysis software they can use to optimize the design before it's even built. Other car companies are this way too, it's why you don't see big gains from catbacks--the factory unit is actually decent.

* In a N/A piston engine, you can swap in a new cam(s). There is no camshaft on a rotary. To get significantly more airflow you'd have to take the renesis apart, which I guess would be approximately the same as porting the heads on a piston motor, certainly not a quick/easy mod.

Skiptomylue

also.. don't mods like Exhaust and intake and what not.. do more for torque? jsut cuz you see only 2-5hp gains from an exhaust.. doesnt mean you arnt seeing more in torque.. thats why some cars "feel faster" becuases there is more torque??

rotary crazy

the renesis is max out at 215 rwhp ( i read some where that amemiya got 220rwhp on stock ports for street aplication) to increase this power level you are going to have to port the engine.

the way NA make more power after all air and fuel mods, its to stroke the engine, for a rotary that means increase displacement either larger engine or another rotor.

I think that for its displacement and stock ports the renesis getting 210 rwhp NA its admirable, to put it in perspective the fd with twin turbos only got 217 rwhp from the factory and you cant do much until you modify the ECU.

dmp

Up the CR to 11:1, Raise the Max RPMs to 11K, and properly fuel and spark and time it, and your renesis would see 230whp, I'd guess.

TALAN7

The issue with the 8 is that it's maxed out. If it was easy to get say 15-20 hp with bolt ons, people would be happy.

I think with this type of performance oriented car with the cool looks and so on, people in the market for it expect a degree of instant tunability. If it was a camry then I don't think people would mind.

Of course the rotary engine is the main issue. Perhaps Mazda shouldn't have put out the RX8 without already having solved a higher hp model ie Mazdaspeed like what GM has with the Sostice/Sky and GXP/Redline versions. We knew of the tuned versions before the na version hit the streets.

Instead what we have from Mazda is them fumbling around with retune after retune 3 years later. They haven't gotten it yet! Shouldn't they have had it from the beginning?

Don't get me wrong, they need to find the correct tune, but doesn't 3 years later and them still retuning make them look a little amateurish?

rotary crazy

maybe even more, but imagine what it would be like driving around with a ballistic shield on your bell housing and the fear of the cluth exploding at 11,000 rpm or the flywheel getting loose

dont you think its just sympler to built a larger engine?

dmp

Dude - that'd give you SOOOO MUCH Str33t Cr3d.

I wonder if scattershields come with window stickers so everyone would know? Maybe I'll put an LCD in my rear window showing my TACH? Hrm...

How about a license plate which read: "11KRPMS"

:D

rotary crazy

Lmao! that would be great

devious12

Mazda can make it more powerful, they just like toying with you and teasing your d*%k I think they all laugh abuot it behind closed doors
