what kinda MIVEC does the 08 have?

ok so i'm doing research to maybe get a new 08 GTS and i see mivec this and mivec that but my question is what kinda mivec is used in the 08 GTS?

if i'm not mistaked the evo ix has just variable cam phasing called mivec and the old RA has variable valve lift/duration and also called mivec???

so which version does the new GTS have? i read posts of people talking about mivec "kicking in" but on the dyno i see no surge of power like in honda VTEC dynos where you can most certainly see where VTEC kicks in.

lastly, if the GTS does have variable lift, then where is the MIVEC point?

thanks for clearing this up

"The all-aluminum, two-liter, inline four-cylinder engine uses dual overhead cams and a variable valve-timing system called MIVEC to produce its combination of power and efficiency".

Mivec doesn't surge like VTEC simply because the torque curve is more lean and evenly distributed throughout the entire band. VTEC on the other hand is torquless during the lower rev-band and much torquey mid-upper rev-band because thats when all their torque "kicks-in" and valves lift.

Mivec point engages at about 2,000 rpm with 135 pound-feet and then plateaus a short time later with 146 lb-ft at 4,250 rpm. Oh, and horsepower - 152@6000rpm.

With these being set i would like to ask, whats the best RPM range for max acceleration/torque/horse with the mivec? im guessing around 4-4.5?

The MIVEC system in the new 4B11 is the most advanced MIVEC to date. It actively and variably controls timing on both the intake and exhaust side. If you watch the 4B11 video in this thread it gives a pretty basic yet informative presentation on how the new MIVEC system works.

ok so judging by the tech video, it's safe to say no variable valve LIFT with the 08 GTS MIVEC. so why have a mivec point at all? why doesn't mivec work all the time if it's just variable cam phasing?

Variable timing is still handy for controlling the power curve, even without the variable lift that the 4G69 has. The engineers probably found that there wasn't a significant benefit to having the variable valve lift.

Or the managers decided it cost too much.

let's hope that they add in variable lift in future GTS models. all this talk about a 2.4 for the GTS is nonsense IMO when the 4B11 is SO undertuned (intentionally). with the variable lift MIVEC added we would see a nice hp bump closer to what the honda k20 makes. a 180 hp GTS would slot nicely in between the regular DE/ES and the upcoming ralliart.

I doubt you will see it in "future GTS models." im almost 99.999% sure, what you see is what you get.

Also, if you read the post about the dyno and how the HP rating standards have changed, this car is basically putting out over 170 horse with 140ish to the wheels.

the DE, ES, and GTS only have minor differences and most of the big ones are in handling and braking.. not power. Which i dont neccesarily agree with but then again im use to the letters GT being part of a line of bigger engined cars. I still think it would have been sick to have a V6 in this thing or atleast like you said a 2.4, but its not going to happen.. not in the GTS model.

I believe Mitsu's view in making these cars was for economic value and everyday driving, with the safety and security of all these extra features (and the higher you went in models, with the GTS being the highest, the safer your car got) such as disk brakes, better suspension and down to even little things like bluetooth, radio control buttons on the wheel so you dont have to mess with looking away from the road or taking your hands off.

So the cars got all the power it was intended for stock, Mitsu made it how they saw fit todays conditions and left room for the tuner option knowing people would still want power. Frankly, i think the current mivec is sexy as all hell, i just want to see a controller for it.

but the GTS is already kinda down on power vs it's competitors. it'll come to a point where mitsu has to offer more power to stay competitive. it's this time that i'd rather see a higher spec 4B11 than a 2.4 like

all the GTS needs is a little more power to make it that much better and to bridge the gap a bit more between the base models and the 240 hp ralliart. imo 90 hp gap is kinda huge.

No, they wont. The standard at which horsepower is rated has been changed with 08 models apparently, so if you compare an 08 lancer to an 07 civic... not a good idea or accurate comparison. However if you compare an 08 to an 08, then you will find the lancer is where it should be.

Read the dyno post and do some research, youll find the lancer has all the power it needs just crappy intake. BTW doo you own a GTS yet?

i know about the new hp ratings but the dyno still shows "only" 140ish whp. i'd love to see the GTS or another trim get 160-180 whp. unless the ralliart is gonna be under 22-23k, imo it'd make perfect sense to have a car with that kinda power for this kinda price. the best part is that, like you said, they'd only need little changes like a better intake to net great gains because the base 4B11 is so undertuned.

nope, no GTS for me. i'm doing my research to possibly get one, but right now i'd wait for the ralliart if it fits my budget.

140whp on a Lancer is spectacular. The 4G94s put down 103 stock. This is a great jump.

How would the Ralliart be so cheap? My GTS was 21k. I HIGHLY doubt they'd drop the RA for so close.

140 whp is great for a lancer, but i think we all agree that the 4G94 was kinda slow so not a great comparison. i envision a more powerful GTS as something to compete against cars like the civic si sedan and sentra se-r. something with comparable power for a comparable price.

my point is that the RA WON'T be cheap. it's gotta have a base of at least 25k like the WRX it's main competition. then there is a large gap to the GTS with a base of around 18k. the most logical step is to make the GTS faster and not add another model to further segment the market.

IMO the GTS is almost there. it looks the part, handles well, standard amenities up the wazoo, but lacks class leading power. all the reviews state this fact. power sells for no other reason than that. the engine doesn't live up to the chassis, and that's a shame. give us a slightly faster GTS that doesn't need premium fuel and the sales will BOOM

Same thing I've been saying for 4 years now... If that's what you envision, then you aren't exactly operating in the reality of Lancerland. The Lancer is what it is. Gotta love it or hate it.

I still disagree. You're putting too much emphasis on comparing the Lancer to other cars. In it's time in the US, the Lancer has always been a platform that offered one motor and differing levels of trim. Then the RA came with a stepped-up motor. is obviously continuing this trend, like it or not.

I guess I just don't see the need for class-leading power. I bought the car based on what it is. Not because it led it's class in X or Y...

i think class leading power is a major key to success. magazine comparo success translates to sales success most of the time. sad but true. you really have to pander to the media to get sales. and the media loves power. thus forth the relatively weakly tuned engine is holding back lancer sales IMO.

i for one am holding out for a more sporty version. i am sure others are as well. i think the RA will be a huge success because it has everything that the GTS has, and then some. most importantly, the price of the RA will most likely still be hugely attainable for most of us. if the GTS came out now with more power i'd not hesitate to get one myself. but for me personally it's not compelling enough right now.

the past strategies of mitsu haven't exactly garnered a lot of sales so i'd say a change would be for the better. the old lancers were SLOW and the lackluster sales reflect the consumer distaste imo.
