Disabling Cylinders

I have a N/T '93 Talon and I'm wondering if there's an easy way to disable cylinders so I can save gas. 90% of the time, I just drive around town, and I never need 1/2 the power my engine puts out. Thanks.

Break 'em :thumbsup:

lol no! do not do that... you'll end up ruining something. what you get for gas mileage now isnt that bad unless something is wrong with your car... it should be around 20-25mpg!

If you use 25% of 4 cylinders or were to disable one (wtf?) and use 33% of 3 cylinders, you would use the same amount of fuel. There is no way to save gas except not to use throttle.

Haha I think he is thinking he can make his car like the new ones like the chrysler sixteen that uses cylinders on demand or whatever.

Break cyclinder and/or car and you save loads on gas. Seriously, just keep shifts below 3k and your good



PS-3000 posts, god I feel like I live here :loser:

lmao, raz i love the pic in your sig. plus its one of the best parts of that movie. lololol

If you want less power and more gas mileage...get a Honduh.

Haha, alright, thanks guys, makes sense. I'm already averaging around 21 MPG in all of my town driving. I guess I really can't complain =) I just thought it'd be interesting if you really could just somehow disable cylinders (without breaking anything). If I still shifted at around 3k I could still save gas. (eh, well, I have an stupid automatic, but it's easy to shift when you want by controlling the throttle).

How could you possibly never need 1/2 the power your n/t makes?! :grinno: j/p ;)

i agree....my 98 nt sucks for power...i dont think i would make it with any less

They're not that bad.....

They're not bad at all. :)

they arent terrible but makes a great daily driver for me

You could do all the performance mods that help gas mileage and dont do the ones that hurt it. Like light weight every thing, I think free flowing exaust, improved grounding system. you know stuff to make your engine run more efficent.

If you "disable" the cylinders, the fuel injectors are still going to pump fuel into them.

Mods don't help gas milage. Free flowing exhaust, along with all air/fuel mods allow more fuel to get through the engine. Gas consumption is directly related to power if the efficiency is the same.

If ya really want to save gas.... try putting stickers on it!!!seems to work on the honduhs lol j/k get a bicycle or an electric scooter!!!! sorry just had to rip!!!

Joe always has to disagree with me :smile:

You dont think a free flowing exaust and a k and n filter would help your gas mileage? Its not a cold air intake, its not taking in more air atoms so it has to add more fuel, Its just getting the air in and out easier. Alot of mods do say "improves gas mileage".

Ive heard of grounding kits helping with gas mileage, but I'm not sure about a more free flowing air mods would do the same

You could shut the engine off and cost around town... or have it towed to where you need to be... That should save gas. haha j/p.

Ive heard of grounding kits helping with gas mileage,

They better :) I should have mine on next week.

if air is going in easier doesnt that mean more air is going in? i see it as if the air goes in easier, more air will goin in within a given time than when you had the more restrictive air filter.
atleast thats how i see it

I believe that a CAI helps gas mileage but I really doubt that a exhaust does.

the throttle plate controls how much goes in. but if you make the intake more free flowing it does improve gas mileage by evening out the air so that the air/fuel charge in the engine burns more completly therefore the same amount of fuel makes more power. so IF you can lay off the gas you get better gas mileage.

Yeah.. sorry I don't agree with any mods increasing gas milage. If you let the engine suck in 10% more air, the ECU will inject 10% more fuel.

On the other hand, certain mods may increase efficiency: new spark plugs/wires/grounding etc helps reduce misfires, which is wasted fuel.

True. But if you install a CAI it will also be bringing in colder air. Which I THINK helps with gas mileage. Could be wrong though

im with joe on this one, i dont see how mods will increase gas milage.

more air=more fuel to be burnt with it...


btw, anyone heard of the fuel additive thats suppose to increase gas mielage?

One thing that I thought of is that full timing advance would be more efficient, so eliminating all of the things that cause knock and timing retard would technically reduce fuel consumption... but we are talking about full throttle, so you aren't exactly saving fuel in the first place. I don't know what timing does at low throttle. Never had a logger :)

If you have a free flowing filter that dont meen you will be sucking in more air. That meens your piston doesnt have to suck as hard to pull the air in. Same with exaust it meens the piston doesnt have to push as hard to get the air out.

Try pulling on a bike pump when some ones finger is over the air inlet, now try when their finger is off. Much easier, but does that meen its sucking more air in? not really.

No it auctly hurts it, Cold air is denser so there is more air atoms in there so the computer puts in more fuel. So hmm..i wonder if you sucked in hot air that would help fuel mileage? I know you would make much less power but i wonder if you would gain gas mileage.

There is no 'easier' for the engine to suck in more air. The engine is going to create a vacuum and suck in air. If it sucks in less, with a stock filter, then you are going to get less fuel usage and also less power.

I put a short ram on my gs and i got better gas milege, but when i got an exhaust it felt ilost gas milege. so i dont noe...

well i get no better sleep at night if people don't agree with me, but at least they know my thoughts. :) If anyone wants to keep going with the thread, bring some proof or just leave it to be that driving has a lot to do with milage, and disabling cylinders is not a good way to do it!

I still believe a intake does improve gas mileage, but on my car a exhaust did not help it the gas mileage went down..

This says that they both do.. so who knows..

"Lots of other performance products can improve an engine's performance and fuel economy, too, including a high-flow intake system and a free-flowing exhaust. It's easy to understand why improvements to the intake system help: If you've ever tried drinking a really thick milkshake through a straw, you know how hard it can be to pull that fluid through an opening that's too restrictive. Your engine may be feeling the same way about incoming air.Exhaust system changes work pretty much the same way: If your engine is trying to force its spent gases out through an opening that's too small, it's wasting energy. Plus, if there's too much backpressure, some exhaust may remain inside your engine, which means there isn't as much room for fresh air and fuel to be burned, so you're making less power."
