I don't want to be fast anymore
 

Hey folks. Proud new owner(and member) of an '01 C5 6speed here. Just picked her up(against my wife's wishes) this past summer and have been enjoying it so far. Beastly(knick name ) definitely gets the looks on the street if you know what I mean haha. Have gotten tons of compliments everywhere.
Only thing I'm having trouble adjusting to is the fuel consumption on this thing. I mean, it's god-darn horrible. I drive a prestine Chevy Beretta which sips fuel, despite it being a really quick car(bunch of mods), and it's almost painful when I have to fill up the vette so often.
Now, i'm at the age where I don't really need the speed of the car to be quite honest so was wondering if I could knock it down a couple cylinders permanently? Any mod that can be done?
I have a buddy who has a new C6 and he's always bragging about running on 4 cylinders to save on fuel when not giving it throttle and it's something I definitely want. Basically, I'd like to know if I can just disable 4 of the cylinders, or 3 if it's more doable, so that I can consume a lot less? Again, I don't really need the speed.
Any help much appreciated. :cheers:

(yeah, that's me in the blue trunks)

Congrats. My 01 averages about 20 MPG with mixed city and highway driving.

Your buddy may not realize that C6s do NOT have cylinder deactivation. The C7s will, but they haven't been released to the public, yet.

Sell it....sell it now......feel like I'm on punk'd.

Pull your pants up......higher...... gas mileage gets better.

Sorry, 1 too many drinks tonight to give a serious response.....

I have a 01 six speed as well and its highly modified I still get 27 on the highway and around 15-18 in town. I had a basically stock 01 Z06 and it got 31 consistently on the highway and averaged around 20 in town. I'm sure I will get corrected here by someone but I have heard that the disabling of cylinders is only effective when the car is up to speed and not pulling, so permanently disabling them would do you zero good. And even being able to disable the cylinders only gets you around 8-10% better economy if even. For the amount of money it would take to accomplish this you would never recoup the costs. If your car is running right and you can keep your foot out of it these cars can get very respectable mileage...

Big as$ picture is big.

Nice shirt. Wait... Wuut?

You bought a Vette and you're worried about gas mileage? LOL

I'm getting way less than 20 mpg. Definitely much better on the Beretta.
But isn't there a way I can just stop the pistons from moving up and down for good. If there is no combustion in those cylinders, than i'm not really wasting gas right? Or maybe disabling the injectors(or pistons) or taking them out completely.
Sorry, i'm not really tech savvy when it comes to this.

Chassed,

I love the car for it's looks and handling. Don't really care for the speed. I hat getting speeding tickets so.

Kinda warm for a sweater......

I feel bad for being a db about this but.....what mods, how bad is the mileage? I was being a d#ck because for what we have, our cars get great gas mileage.....I'm getting 29 on the highway.....

Uhm... nope. The vehicles that have actual Displacement on demand, or also called active fuel management typically accomplish this by controlling the valves along with the fuel to the cylinders. If you don't control the valves they will still suck air in which is where engines can loose power at lower rpms while highway cruising. Because the throttle is barely open and the engine actually has to work to pull air in past the small opening.

If your getting less than 20 and your not driving like a mad man there is something wrong. Check your plugs, air filter, fuel filter etc...

I don't have anything done to it. It's stock. I just got a tune up at Pep Boys this September. Everything checked out ok.
Would I be able to just take 4 of the pistons & injectors out? I mean, there has to be a way I can just kill half of the engine. If the cylinders I don't want aren't firing then I'm not burning any gas in them right? I've heard of people unintentionally losing cylinders. So I WANT to lose them. How do I do this?

Drop pan and pull heads. Take out all pistons on the LEFT side. Put everything back. Keep left side plug wires as spares. Use ONLY ethanol 85 from the time you put it back together. Report results.

:D


Oh, and WELCOME to the forum !!!

What a fake post... IB4TL

Is this April 1st?

1, 2, buckle your shoe !

Ummm, I have no reason to lie about this. Are you guys serious?

I bought mine FOR the MPG lol. Previous DD was 12-15 city, 20-22 highway

Ohh.. and IB4TL.

Obvious troll is obvious

How funny.

Are you serious?

You should swap your LS1 for a Honda Vtech engine.

:lurk:



007
:cool:

Engine swap
 

:willy:I'll bet you could swap your old nasty A$$ LS1 to somebody for maybe a honda motor:smash:

gas mileage
 

My C5 6 speed is my economy car :cheers:

:lurk:
Fingers crossed that this goes on for many pages. :crazy:

Does the OP have any knowledge about the combustion engine?
If you want a 60 mpg car, get one of those hybrid "things"
Why did you get a Corvette?
Trying not to be mean or anything, high performance and over the top fuel economy dont go hand in hand usually........

wow really...you need to do some general maintenance on your car ..i have an 03 z06 and i get well over 30 mpg hwy..and your buddy is a moron the c6's vetts can not select any type of active fuel management stock or after market...

This has got to be a troll post. That's all.

Around town,,,SKIP GEARS!! I usually run 1st,3rd,5th,6th,,and get low 20's in city driving. These cars with the 6speed will get around 30mpg in normal highway driving. Your car is not running well,,OR,,you are sticking your foot way too far in the throttle! Depending on your driving style,,you can either get great mileage,,,or if you try,you can knock it down to single digits.:thumbs::thumbs::cheers: PS,,I don't always drive conservatively,,I've also cracked off a 13.08/110.24 at the strip,,,time and place for everything!!

I have driven my 2001 automatic every day for over 12 years - only in-town driving - and my monthly fuel bill averaged $68/mo the past year running only Premium? Can't imagine paying much less?

No, you can't remove pistons. It will shake like a vibrator. You can't disable cylinders either, it will go into Reduced Engine Power mode and barely run.
Maybe read up on hypermiling.
Or just drive the Cadavalier.

You accidentally bought a corvette instead of a miata.....

http://i54.photobucket.com/albums/g1...oco7/Miata.jpg

I'm with the guys calling Troll on this one...doesn't know anything about cars yet his daily driver is a riced out beretta(which could explain not knowing anything about cars)??? Not buying it. Though it is rather funny :rofl:

maybe swap the ls1 lump for the beretta lump? (looks great with all that red, and would really be a hit in the vette!)

What's a troll post?

Thank you

Consider a Sky or a Solstice.....and another forum

DON'T KNOW WHAT TO SAY? :crazy2:

Try revving the engine to about 7000 RPM, you'll surely lose at least a couple of cylinders

The best way for you to increase your mileage would be for you to lose some weight. Your way to bulked up to be driving a corvette AND get good mileage.

Weight is a mileage (and performance) killer.

Have you ever seen a bulked up race car driver? NO!

One pound of body mass equals 1/2 mile per gallon plus or minus.

So lose some weight and let us know what your mileage is then.

Man, some of you guys are harsh.
For those asking, I got a vette because I always liked the way they looked. You know...lots of people who buy a Veyron will never get it over 150mph.
I don't see why trying to deactivate 4 of my cylinders sounds so outlandish to some of you.

never met someone that owns a corvette this clueless.......its possible.......but not likely. i think this is one of those 60 minutes segments ...... what would you do if???? you met this guy and he said.... i would ROTF and LMAO.... PRICELESS

I'm just baffled that there is a "fast" Beretta out there. Also, FWIW, your Corvette should get better gas mileage than the POS Beretta.

I remember back in college my close friend bought a new 96 V6 Beretta, and he thought it was fast - but yet my SOHC base model 164BHP Stealth would pull on it. :eek:

It's like being a man, then wanting to cut your nuts off. Capisci? :toetap:

:iagree:

If I unplug the spark plug wires on the cylinders I don't need, will it still be injecting fuel into them? I'm not understanding this. Should I worry more about the injectors?

Seriously, just sell the car.

On a more "serious" note, I'm curious as to what gas mileage you get in both your Vette and Beretta?

Getting around 25 on the highway. Well under 20 city.
My Beretta is fast and it easily gets over 20 city. Not sure highway.

Define "fast". Also curious as to what mods you have - it would take basically a complete engine swap to make a Beretta "fast". And with all that, you wouldn't have a "fuel efficient" Beretta. So you either have a slow Beretta with decent gas mileage, or a "quick" Beretta with crappy gas mileage.

You should be getting closer to 30 on the highway, and high teens in the city (in the Vette).

Must be from the Beretta forum playing a prank on the vette forum:rofl::rofl::rofl:

I find this somewhat hard to believe. I had a beretta as a second vehicle and the gas mileage was worse the my C5, and to top it off my C5 has mods. Are you sure your calculating your consumption correctly?

This post is making me LOL. You can't find a high performance car that gets better mileage than a Vette. I would sell the Beretta! :rock:

December 2012 has sure brought in a few new trolls for some reason. Full moon all month?

Just remove 4 spark plugs of your choice and be done with it.

Actually, I admire his troll-ish creativity! That fact that he took the time to find a picture of a Beretta (a car which I completely forgot ever existed) is classic. Plus the first post/first picture being shirtless adds to the mystique!

Thanks! I really enjoyed a nice laugh to start out the week.

...and in answer to the OP's original question, I suggest pulling out every other cylinder. That way, the reduced engine power is evenly distributed, your gas mileage improves to 45MPH highway and the Corvette ride-adjusted swaybars and suspension will sense the reduced horsepower and the Corvette DIC will automatically convert to "Civic Mode".

Good luck!

:cheers:

And then on top of all this - check out his username! Good stuff. I'm confused as to why he didn't choose "BeastlyBeretta"?

True-all my friends with Veyrons just drive them to the grocery store and back-if you read the fine print in the owners manual,that's what they're really made for.

Just leaving the Vette in the garage,and getting a "My Other Car is a Corvette" bumper sticker for the Beretta will save the most gas,and people will still say "Wow-that guy's got a Vette"

It's a 2.8L. I have a custom bosal exhaust on it and some spark plug wires that were already on it when I got it.
I'm not saying it's faster than the vette, although it does feel pretty damn quick. I'm just saying that it gets me good gas mileage. I don't fill it up as often but I drive it more since it's my daily car.
C'mon, I can't be the only one who is asking this? I have been looking and there are several others complaining about the bad gas mileage. All i'm looking for is a permanent solution, but I don't want to get rid of it because I love the car so much. Help me out here.
It's a fact that 4 cylinder engines get better gas mileage. I'm not crazy you know.

All you have is an exhaust on it? That car wouldn't even be in the 15s, and would struggle to be in the 16s. To even remotely compare the power to a 6 speed C5 Vette is laughable.

A permanent solution is to sell the car.

Is it safe on the engine in the long run?

Wow, I never compared them. You should learn to read. C'mon you guys.

You said "it does feel pretty damn quick". We are telling you it is not. A 16 second car is not even remotely quick. Nor does a 2.8L Beretta get good gas mileage by today's standards - it is a dinosaur of a car.

I can't believe you are taking the "pull 4 spark plugs" comment seriously. C'mon man!

Tis the season for Trolls!

If you drive the Vette with a light foot, it will get better mileage than the Beretta!

http://fueleconomydb.com/index.php?-...=40&-mode=list

I have an '89 with a 2.8L. Those aren't for the 2.8.

You betcha.:thumbs:

Just alternate which 4 every month that has 31 days on the 3rd Wednesday at 1500hrs GMT.

The 2.8L isn't much better:

http://www.automobile-catalog.com/ma...etta/1989.html

18 city/29 highway, with a blazing 16.9 1/4 mile time!

Basically exactly the same estimates as the C5 Vette (minus the 1/4 mile time, of course). :)

Okay, so my idea about losing weight was just a joke.

But seriously, if you want better fuel mileage then forget about the idea of reducing cylinders. It's all about fuel delivery.

A 2000HP dragster will get the same mileage as a 4 cylinder motor if the fuel metering system is done correctly.

You need to get a variable fuel pre-compressor/expander filtration system on the Vette. A good fuel pre-compressor compresses the fuel before it gets to the engine and increases the volumetric efficiency of the fuel therefore giving any motor better fuel economy. Compressing the fuel before combustion removes the air from the fuel and condenses the fuel so that a smaller amount goes farther. After compressing, the fuel is then released into a expansion chamber that increases the volume exponentially before going into the motor.

Here is a good example of a fuel pre-compressor/expanding filter.

Actually quite simple.

Good luck.

People always want to talk about the Beretta. Forget that car. I regret even mentioning it.
All I know is that I fill up a lot less with it, but drive it more than the vette.
And no I don't have a heavy foot when driving it. My wife would kill me if she found out how much I spend filling that thing up.
Are you serious about changing up the spark plug wire connections every now and then?

ARE YOU SERIOUS.... ??????????????????????????????

This forum has really hit bottom wth people like this.
The pristine Berretta comment was the best.. just look at the pristine engine bay.

I'll bite with a serious answer. You can't do what you want to do to the car to save gas. Probably the best thing you could do is swap out the engine for a 6 cylinder or maybe a 4, but it would probably cost more than your interested in spending. On the other hand, you'd have a one of a kind C5, and that's bound to increase its value. A 6 cylinder from a Nissan 370Z would be great. If you decide you're tired of the Vette, I'll trade you straight across for my wife's smart car. 3 cylinders, 70 hp, and an automated manual transmission. It gets around 40 mpg and is a blast to drive.

DUDE, go to Google and READ and Displacement on Demand (or MDS which is what Chrysler calls it). It's not a simple as removing a spark plug wire. Without the onboard computer knowing which cylinders to not fire the injectors on, it also has to realize which ones on each side of the engine need to be deactivated in order to keep engine balance. You also have to have SPECIFIC criteria as to when to deactivate these cylinders in order to not notice the different modes of operation. You also do not want a bunch or error codes (which you would get pulling plug wires).

Trade the Vette before you hurt yourself.

But if I cancel out the cylinders that are directly across from each other, there shouldn't be a balancing issue right? Like if I unplug them evenly. Do you see what I am saying?
I just want to make sure i'm doing this correctly. I don't want to mess anything up.

OK, Beastly, my fellow forum members have been having fun with you on this one. We usually let posts like this go for 5 pages before enlightening you to the real world of Corvetting. Consider this an initiation.

Being new to high performance automobiles, the first thing you need to know is that we register fuel consumption in gallons per month (GPM). This rating was instituted back in the late '70s, not long after the fuel crisis of that era. It was thought that this new way of judging consumption would totally baffle penny-pinching spouses and clueless environmentalists. And it worked! As a result, high performance cars are back, sporting the most horsepower than ever. Because GPM is inversely proportional to MPG, GPM has decreased accordingly, yielding the most efficient, highest performing cars ever. Sounds confusing, but just a different way of looking at performance. Kinda like converting chin-ups to pushups (which is not related to the effect that a bra adds to aerodynamics).

Now, on to your concerns about bettering your current consumption (not to be confused with electrics and/or hybrids). Simply put, drive your Corvette half as much and your GPM will decrease accordingly. As far as your Beretta goes (and this is just a shot in the dark), sell it and put the $ into car care products so the next owner can enjoy your insight and forethought. I hope you don't think this train of thought is cavalier, but is one that most of us with high performance sports cars adhere to, not unlike a well-applied can of Plasti-Dip.

:flag:

Ok. So is this what you mean? Should I deactivate opposite connections? Would the balance be ok like this?

:D :cool: LMAO!!

No. I think he meant to unplug all 8.

put a Chevette engine in it. it still has Vette in it LOLOLOLOL :smash::smash:

:withstupid:

Every now and then, one comes around :lol:. Kind of reminds me of the Kung-Fu dude on here recently who was stomped by three dudes. :eek: :hide:

It's killing me that I see a U.S. Army plate on the front of the Beretta too... :U

Ok, so which ones should I disable to keep my balance? Is there any specific ones that are best? Last thing I need is to muck anything up that could cost me in the long run.

http://img812.imageshack.us/img812/5133/dsc0023ti.jpg

Nice chuckel this morning thanks :D

That blue intake on the Barretta has to be worth a 50 shot lol

You will have perfect balance if you disconnect all 8 - and wonderful gas mileage to boot! :thumbs:

Serious replies please. :cuss

:lol: :rofl:

I'm just waiting for the punch line at the end of all this..."GOTCHA BE-OTCHES!!!!!"

Lmao

!

You should've bought the 4 cylinder C5 to begin with. Then you wouldn't be having to worry about it.

It's ok to just admit that you don't know instead of being an ass about it. I'm looking for serious responses from knowledgable people. As I can see, not many of those around.

NO, did you even RESEARCH it like I said? It's the FUEL that gets cutoff in DoD systems, not spark.
http://en.wikipedia.org/wiki/Active_Fuel_Management

But if the cylinder is not firing, then wouldn't it be doing the same thing? Wouldn't the pistons not make combustion?

Only with the "Active Deisel" option. Check your VIN.

You want fuel washing down the cylinder that has no spark SCORING the cylinder and diluting your oil? Go for it and let us know how it works out for you.

2 cents
 

I think I see how to make your beretta faster and possibly increase mpg,,,,,I'm pretty sure if you rerouted your spark plug wires over the top of the water hose you would possibly get 15 more horsepower because the wires are arcing out on the valve covers. I have been advised by a chick-fila associate on a couple of occasions if I would replace my ls1 with a six cylinder I would be faster and more powerful !! So maybe you are on to something.:ack:

http://www.getrichslowly.org/blog/20...-fuel-economy/

If that doesn't help, go ahead and sell your car (don't resort to something so assanine as to disconnecting plugs).

Wow, get a life man. No need for idiots in this thread.
I can't believe some of you are giving me such a hard time here. You know, not everyone needs to run on all 8 cylinders. I'm just trying to figure out how to do this.

Try starting out from a stop on 4 cylinders-see what you have. Without and AFTERMARKET fuel management system, YOU WILL NOT DO THIS!

Again, trade the Vette before you hurt yourself.

If all you guys think the OP of this thread is a real A$$hole... forget about that... You know who the biggest A$$holes of all are??? Its all of us who actually posted in this pathetic thread.. No one is "THAT stupid"
He is manipulating everyone here... its a sad commentary that everyone fell for this. Like I said. No one is "That stupid"

I should disconnect the battery when doing this right?
Also, what kind of fuel management would you recommend. I should definitely talk to my guy who does all my car work because atleast he knows what he's doing and i've never had a problem with any of his work.
I would do it myself, but I hat doing this type of stuff.

I bet no one that buys a veyron complains about fuel economy and wants to disable cylinders.

This is a funny thread. I hope it doesn't get locked so we can enjoy it for a while. Op is either a troll or stupid.

Wow, bro. Do you need a hug or something.
Stop hat'ing. Stop assuming things. You don't know who you're talking to. Why would I waste my time making stuff up? I'm a busy guy. I have a wife and a life.

Give it up. :crazy2::crazy:

Not sure what you really came here to learn but,,,forget the idea of cylinder deactivation. Unless the vehicle was equipped with it from the factory, it ain't gonna happen. I think you know this and are having fun but its time to put this to bed. Most here will tell you to stay away from PepBoys and I agree. If you really want better mileage change your driving habits and get the thing properly tuned. This post would have been better served on 4/1/13
