Although i doubt my post is going to end this debate. But the sad truth to some is that the CVT is the better option, and here is the main theory why.

With a CVT and a piggy back/engine management system, it is possible to create shift point profiles that will maximize HP or TQ for different applications.

Something that I am looking into is, the ability to create a power profile or a economy profile or a TQ towing profile.

with a CVT it all can be done faster if everything is set right.
Now thats the advanced answer for the advance side of the question.

The double edge sword of CVT and this is where I hurt the other crowd, is that this CVT is a walking time bomb, if one thing semi major fails with it, the whole thing is junk. Its already been said that if there is a major failure, its better to replace the unit instead of attempt repairs.

That said, and with Mitsu's warranty they seem to have alot of confidence in their transmission so we will see how things turn out as the years go by.

And you cant go wrong with a 5 speed. its simple to use, its tried tested and true. you can abuse it if you know how far you can take it.
So when you stand back and weigh you options, the 51%+ side of this debate goes to the CVT.

A computer can be exact, and faster then a human. But of course, hahah who wants a computer driven car to drive us human around, or to fly a plane... lol So thats a funny thing to think about.

I perfer the pilot even after a drink or two lol :P

There is still one thing wrong with your statement you cant launch a CVT like you can a 5 speed. And when you go to more HP with a turbo/super charger you can put a twin or triple racing clutch to launch even harder. Almost all racing (except F1 and they arent using a CVT like mitsu's) uses a Manual transmission becuase you have more control over the cars revs and thats the best proof of why MT vs. AT always end up with the MT on top.

Manual all the way. I understand that a computer can shift faster and more precisely than a human but it simply does not feel the same. I would rather be slower and actually be driving a car than feel like my computer is a chaffeur.

yes and no, in regards to your counter argument.

I am assuming that a CVT can be constructed for power use.
If the CVT was made of sturner stuff, in regards to the pulleys and bands used, then launches can be electronicly controled and programed.. it wouldnt work now because the CVT has logics in place that will not allow you to do that.
Similar to how stability control / traction control safeys spoil the fun with other cars. you could rev and spin out a CVT if the safety was off.
But you could program the perfect launch.
I beleive this is already done with some of the EURO super cars. I will try to find the video on TOP GEAR. there is a super car that utilizes a CVT system. Its disgusting on what you can program cars to do.
A CVT can stay in an exact RPM ZONE, a manual transmission can range shift well but can not stay on point, cant make additional adjustments on the fly as well based on conditions.

In that regard i disagree


The yes part of your counter argument is that, current LANCER CVT will not launch properly, nore do what is stated above due to overides that protect itself from harm. For good reason, boost applications will harm the CVT unless upgrades can be made to absorb the tension and shock. I say this based on observations made in recent tests conducted by myself a few others working on upgrade parts.

But it would not be hard to program such behaviours into the ECU/CPU, to remain in a RPM range is not difficult to program.

All you would need is a 3 way switch,

NORMAL MODE

MAX TORQUE / PULL

MAX HP

I would choose the computer any day if it ment racing for pink slips. haha take it from me. I work as a NYSE Daytrader, and computer program trading is taking over, its like fighting the borg man. they improve and over take the human trader. half the guys working with us are not here anymore, cause they couldnt adapt. I hate computer programs to be honest with you, but hey, if you are the guy making them and making money then its a different story. hhehe

IVe had 4 cars that where manual, i use to think it was the best. then i got my CVT.

Another thing having to do with the tests done recently, is that with power mods
low end CATBACKS, Cold Air Intakes, Headers. High end TURBO Kits etc.

The RPM ranges of power become more defined and more rich. IN STOCK form everything looks smooth mountains on a dyno chart. when you add those those upgrades above they turn into more defined peaks. A CVT Computer could keep the car in those pockets of power perfectly, with a 5 speed manual, your at the mercy of how many gears you got and riding the shifts hard and tight.

I agree with Showtime AND Evo Soul.
A manual, gives you a full control and can get harder revs. I stated that earlier in this thread.
Disadvantage is the pause points that a manual does. Don't matter how good of a driver you are, you are going to have pause points.

Hence: Lost time (no matter how much power you have to make up time; it gonna happen)

CVT: Time can be programmed and calibrated for the perfect launch, shifts, etc.
The advantage is that if a CVT can be tested at a higher HP and calibrated again and again, it will have the potential to beat a manual.

Mitsubishi stated that themselves. That is one reason why the DCT on the X is coming out first to show you this theory. The manual is coming out for tuners and for people who just want to go real fast.

What i have a problem with this idea, is that this is not 'user-friendly'. You have to have the exp to understand the DCT in the X or the CVT in the Lancer.

So this agrument as we have seen in this thread can go back and forth.
(IMO)

Well the reason why it goes back and forth is because we are trying to apply it to a real Mitsu Lancer application.

The theory side of everything to me at least is clear, CVT would win out every time over a Manual. due to the fact above.

You can design a Manual as advanced and hard as you like made of titanium if you like.

if a CVT was designed to take on that power delievered from the engine. THen it will win.

it currently wouldnt win, because it would break, or at the very least, limit itself before it breaks (Transmission Govenor) so to speak.



In current form just lining up the two cars side by side, with no tweaks. a Manual should slightly beat out the CVT in its current form. It just isnt programed for speed, vs. economy.

I have driven MT for years and i was looking for a change.
And now I made the choice and am quite pleased with the CVT.

But this comment is solely for you on this and no other person for that "CVT for Ladies" comment.

While your still dwelling in the past with YOUR manual, I will look to the future with all the latest tech that is "EVOLVING."
(Like that word huh? if you are an EVO lover)

So while your driving fast as hell on the ground, I will be flying much faster in the sky.

It's about innovation and evolution, kid.

So here's to my new found brothers here who believe in the future and not dwelling in the past.

(Saloo)

Lol I will. It takes a super man like me to use the three pedals, drink a beer and grab a girl's titty at the same time...and I can and do.
chino_ali, people have said that for years in regards to automatic transmissions, alternative fuels, fancy power systems but nothing feels as sporty as a gasoline powered car with a manual transmission. I understand the appeal of a CVT but I'm just a transmission purist.

Cute. On both comments.

"It takes a super man like me to use the three pedals, drink a beer and grab a girl's titty at the same time...and I can and do."
(Been there, done that.)
With CVT I can multi-task even more.

On the part where people have been saying that for years, well that is true,
but times have changed, compadre.
I am sure you can see that, now.
The tech is finally affordable now, before, it was an idea, not reality.
But now, it's available for the public. It has become a reality.
Technology is becoming more plentiful and being utlized now.
From nano tech to quantum mechanics. It's starting to slowly flourish.


Oh well. all good.
