how can i get more torque ?

Rotaries are torque less, get a V8 if you want torque.

If you have a N/A turbo it or put a supercharger on there.

just watch the movie, i saw it last night....it was AWESOME!

what are you towing?

keep it at mid range Rpm's all the time https://www.nopistons.com/forums/pub...IR#>/smile.png

downshift https://www.nopistons.com/forums/pub...IR#>/smile.png

Assuming your injectors are clean, you should have all the torque you need. These cars do like revs, so if you are short-shifting it will feel like a dog. Keep the revs over 4k, and you should be grinning.

If you still need more torque, go buy a Dodge diesel truck. https://www.nopistons.com/forums/pub...#>/biggrin.png

son, its wrong to ask for torque when you have an rx-7. its just like asking to be stoned to death. https://www.nopistons.com/forums/pub...#>/biggrin.png



like he said, put a v8 on it if you want torque. hell, im doing it to one of my rx-7, just for shits and giggles

it's not that rotaries are weak in torque, it's that they aren't designed for it.



light motor + light car + high rev hp = fun sports car. If you want loads of torque in a car that you have to shift 3k rpm before redline get a mustang.

dont ****** tell me to get a ****** truck, ok. but it would be nice to have more ****** torque. you know off the ****** line power. so dont make ****** sinde posts.

what movie ?

"torque," I'm guessing...since the topic is "torque," and there's a movie called "torque"









sorry, I'm in a "be an ass" kinda mood right now. must be the shitty weather.

if your car is running properly and u stilll want more tq sel and get something with a displacement of over 2.6 liters or something very light with a medium sized motor.

torque can be affected by your gearing.... so get a larger ring and pinion ratio



maybe find a rear end from a GTUs which has a 4.30 rear end as opposed to stock 4.10

chlll out kid, ur new to the forum dont think were al flame happy arrogant people but u gotta understand that asking for torque outta a rotary is like asking how to make stew with a george forman grill or how to catch a shark while flyfishing. we got cars that rev high are light and make good power but undfortunatly with a highrevving motor torque is something u really can never have.



if your looking for small gains you could always go for mods that will free up breathing like exaust and intake just make sure boost levels stay the same. im honestly not too sure on how all this stuff affects ur torque



one think id stay away from is a midpipethough cuz that kinda kills ur low end if i remember correctly

****!.... **** **** ****...... you got ****.... fuick that ****....**** it..****....i like to say ****...im 12 year old....****

Like everyone said, rotaries don't make a lot of torque. I recommend getting an exhaust system that helps out. I'm running dual outlet header into dual presilencers into single straight through muffler (right now). It is the torqueiest setup I've felt on an n/a. But, yeah, for the most part, s/c is the only choice for high #'s.



If you're really desperate, you could always carb your engine or drop a 4 port 13B in there from a REPU, but that's kinda extreme.



Oh, and don't fly off the handle like that. I liked you from the start and like helping you out but more comments like that and you'll get no responses from me and a lot of other people. That is not proper behavior on this forum.



Also, you guys shouldn't be dicks to new guys, just answer his question. Rotaries can maxamize their torque even if they aren't making a lot.

i agree with mike....... midpipe will kill your torqu



it killed my torque so much that i now shift about 1k rpm higher so the car wont stutter

i dont think midpipe kills the TQ all that much, i actaulyl thought it was better, on both the NA and the FD...maybe its because i dont try to launhc my car at 1k rpm

i meant that 1k higher on everyday driving.... before i would be albe to shift at 2.5k now the car would stutter if i did that....

i can see the midpipe having two things to do with torque



1. removal of the cats and a hollow pipe installed....will remove restirctions, so you might lose some backpressure, and therefore some torque



but



2. removal of the cats and a hollow pipe installed....will remove restirctions, so you will be running more psi from the turbine....and that will translate into more torque and horsepower....for na you might lose some torque but gain top end







for NA i would stay with a 2.75 diameter

shorter rear end, smaller outer diameter of tires.

You can drop a v8 into your RX-7 would probably be the best approach to more torque.



Also, if you have a turbo you have plenty of torque. My car made more torque than hp when id ynoed it 192/196 and i hit peak torque at 3500 rpm which lasted all the way till 5k rpm.

thanks for that. i didnt like of that.

ok for the everone else, i know that rotarys dont make torque but i wanted to know if somone new something i didnt. that is y i asked. then i get people being jerkoffs.

and i would [COLOR=red]NEVER[B]put a piston engine in an RX, i would kill my self before that.

people were only jerkoffs after you went out on a yelling and cursing spree











whats wrong with piston engines in an rx7 body....or are you one of those "i just got my rx7 last week and think im special cause i have a rotary engine and its god" kinda guys

it's the torque @ the rear wheels that matters, and rx-7's have torque at the rear wheels through gearing, thats why they are still quick with relatively low torque from the engine. high revs + short gear ratios == torque multiplication == fast car. If you want more torque @ the engine, add nitrous, turbo, or supercharger, or more displacement (more rotors, 20b?). If you're only concerned with torque at the rear wheels, make your engine rev higher while still being in the power band, and get shorter gearing (can be done by changing rear end, tire diameter, or transmission).



I prefer the smaller diameter tires, shorter rear end, and rev higher appraoch. Keeps weight down, lowers center of gravity, while improving acceleration. And if you increase the revs enough you don't have to lose much top end speed.

get a 50 shot of nitrous with a timer on it for below 4k.like pengaru said it can also be in the gears but you will have less top end. super chargers are nice for low end tq. another way is to create more back pressure in you exhaust, i have heard of somekinda valve that regulates back pressure for more tq. or go with a 20b not that i dont like v8s in rx7 its just not for me i would rather have a 26b https://www.nopistons.com/forums/pub...#>/biggrin.png

Heavier flywheel.

https://www.nopistons.com/forums/pub...1047683785.gif



you're joking, right?

if i put in a 1000 lb flywheel id have torque out the wazooooo

One thing is though it doesn't matter how much torque you have if youdon't know how to use it. You go out on the streets asking this same question and i bet you'll get the response "its not how you stand by your car, its how you race your car.'



Meaning, its doesnt matter how you stand by your car, what matters is how well you race it.

Out there on the mean streets, right?



Moving on...



The flywheel comment is valid, though I wouldn't suggest it. If you DID have a 1000 lb flywheel and got it up to speed, it would have so much rotational inertia that it be immediate power as soon as the clutch engaged. It's all about that potential energy thing. Of course, you'd proabably spend about 20 minutes getting it up to speed each time and you'd have an extra 1000 pounds.



Be cool to try something like this and I heard it's been done to an extreme, but I've never seen it.



Redwood

Not at all. :]



Rotational Inertia

yes, I understand rotational inertia, it does not increase the torque of your engine.



the effect of a heavier flywheel is easier starts from a standstill, less likely to stall the engine. Once your clutch is fully engaged, and your tires have full traction, all advantage of whatever rotational inertia your flywheel has is lost and suddenly you have more rotational mass to accelerate with the available torque of your engine.





you want more torque available at your wheels to accelerate the mass of your car?



GET A LIGHTER FLYWHEEL

I feel confident in the fact that a car with a heavier flywheel would put down more torque than the exact same engine or car with a lighter flywheel on a dyno.

i see no way or reason this would be true





lessening the amount of rotating mass will free up anything there....it wont give or take away any power and torque., but it will free up whats dormant

I might modify my statement and say that the results may not show up on the dyno but instead would show up in the reduction of an E.T. at the drag strip, most likely.



Not only would the resulting torque show up off the line with a heavier flywheel but it would also show up between gear changes, especially if the transmissions ratios are wide.



Either way, right or wrong, I would like to see a dyno plot.

Dramon, please do not quote fast and furious, you only make yourself look worse (not exactly posting at the top of the food chain as it is)



As far as the light/heavy flywheel it all depends on what you are looking to do with the car. I have a ORC 600u twin plate clutch sitting here, it weoghs approx 28-30 lbs complete, which includes the flywheel, clutches, and all the hardware. For applications such as a drag car or high horsepower turbo street car I would go with the heavier flywheel, for the inertial weight they have, on a road racer or autocross car where you are in and out of the revs constantly I would reccemend the lighter flywheel to get the engine to spin up and into the power range faster. Now it sounds like I am contradicting myself here right? The point I am trying to say is the heavier flywheel will keep the inertial speed of the flywheel in the power range on a drag car between shifts a lot better than a lighter flywheel, whereas in an autocross or road race you want the engine to match the gears a lot faster, less rotational weight will give you better control of the power band in short bursts than your engine fighting the heavy flywheels.



For the torque stuff, well as everyone has said there is not much to be done about the weak torque the engine has from the factory, I would suggest possibly doing a forced air induction like a turbo or supercharger. If your looking for a kick in the pants off the line and not a big hp increase the supercharger would be the key, if your looking for a lot more power, 4 port motor, sideport and a turbo would be the better route, no matter what you choose, there is no cheap way to do this.



Good luck
