Does anyone have a idea why my car would be revgving hard @ 110kph

I've got a '95 KS XI with 264,000kms and at 110kph its revs bewteen 2,500 and 3,000rpm :O! is this normal for the 6G72 in teh 2nd gen or not? my g/f's KS EI sits around 2,000rpm @ 110kph....

alltho mine does have a adjustable fuerl presure regulator, over sized throttlebody and pod filter, and ~100kg of boot install you wouldn't think it would make it rev that much harder


btw its the 3ltr v6 auto

If it's auto, I wonder if the gearbox isn't locking up like it should?

Mine is manual is does 2600rpm @ 110... if that gives you any idea. The manual ratios are shorter though, so it's probably irrelavent.

Hi,
I Know my manual 3L 98 sits on 3G at about 120 but the auto should be lower. Do you have a CAI setup on your pod? If not it could be struggling with the hot air.

Thanx.

I was told it could have somthing to do with my CAI.... I have a cutout on the front bar, and its just the pod with a preif shield around it but still gets warm around there when the motor is at normal running temp....

this is a dogey pic but you can sorta see where teh pod comes out.... so dunno if it could be its getting warm air, the car came with the pod too so I can't exactly put it back to stock just to see....

My g/f's dad was saying my auto might have diffrent ratio's then the auto in my g/f's car dunno....

Mine was replaced 3 or so years ago with a brand new one.... so I can't imigane it would be *****....

could it jsut be the trans needs a service???

Was also told it could be cause... "the 225/50r16 tyres are under sized"

oh yeah fergot to say tho at 60kph it revs around 1,500 - 1,600 which is same as my gf's so :S

so if it was gearbox ratio's wouldn't it rev hard at 60 too cause its in 4th by then...

Yeah you right it is a dodgy pic. Odds are if the pod is behind the radiator and not in clean air it's going to be hot.

it's benind the battrey.....

only pic I got rest are on mum's pc which is a good 450km away lol....

i didnt know the 2nd gen 3L was a 6g72 ... learn something everyday :S

I own an DOHC 3ltr and its a regular thing to be that high in the revs at 110-120... it shifts into 4th gear at precisely 124mph... Ah wait... my drunken ass just got the fact that you werent talking mph and was infact kmph

so 110mph being about 65mph... if you're in 2nd gear doing 110 then thats about right.

3rd, at 110 and that high in the revs then you might have an issue.

Are you driving with the O/D button on or off as this will have a HUGE impact on the amount of revs in relation to gear.

Yeah its a 6G72 12 Valve

the 3ltr TE/TF/TH (I think I heard some TH are a 3ltr) is a 6G72 24 Valve

O/D on with cruise control set.... I know it makes a huge differance gotta have it off in my car commin out of adelaide down the freeway :( and she screams doing that :D

Are you certain this is in 3rd gear as it might just be holding 2nd for too long?

I'd be looking at tire sizes... at 60km/h if it's the same as Bron's (or there abouts) the tires aren't spinning too fast, so the error isn't huge.

But at 110 km/h (even though you'r on P's :P) the error percentage is huge, and hence the different in revs between yours and Bron's. The best way to find out would be to put Bron's tires on your car and go for a drive on the same roads at the same speed ;)

Shouldn't be trans as it was replaced a couple of years ago....

and Travis, did I say 110kph :$ whoopski I meean 100 :badgrin:
Yeah, I was sorta thinkin of what my g/f dad said and possibly be ratio's, I don't see how wrong size tyres and make it rev THAT much harder....

Dunno if I've done somthing because when I went to melbourne the weekend after I got teh car it was really good on fuel 600km to like 3/4 tank, but when I took it to mount gambier at x-mas I got like 450km to like almost a full tank :nuts: Alltho it now has the boot install which doesn't weigh it down that much to use that much more noticable fuel :confused:

Hi guys
the average revs at 100km in an auto is 2100rpm to 2300rpm. any higher than this could be the result of the tourque converter not locking up. Tyres should not make a differerences unless you have pissy little lancer rims (unlikely they dont fit).

cheers dave :nuts: :D :nuts:

i didnt know the 2nd gen 3L was a 6g72 ... learn something everyday :S pretty sure gen1 magnas had the same 6g72 3litre overseas... the car is known as the v3000

only difference the orientation of the motor and gearbox... transmission is on the drivers side, same as a 4 cyl... i think in the gen2 onwards, the transaxle is the otherway around (not for 4cyl models though)

they are uglier than a gen1 magna though...

mmm could be that :s I'm around ready to get rid of my car if it wasn't under finance :( it's pissin me off at the moment.... problems ya get with a 10yo car.... need sumthin new like a ralliart :D

Hi pplz

The tranny in mitsubishi's has nearly always started out on the drivers side (note there are a few exceptions).Through till 95 all magnas, gsr's, lancers. had the tranny on the drivers side(in australia). in 96 out came the 24valve motor placing the tranny on the drivers side in the magna. this followed the release of the evo 6 which did the same.
Im still tryin to source some 24valve heads to drop on my 6g72, now that ive found another mechanic willing to help out and give it a go.

cheers dave

Definitely sounds like the torque converter.

pffffft 100% normal; only gen 3 v8's rev at 1600 at 110km/h mine sits at 3000 @ 130km/h and around 2700 for 120km/h

I have the opposite problem in my KS Verada. It revs lower. Tho on the highway at 100km/h it will rev around 2200, 110km/h maybe 2400. But when cruising at 60km/h it ranges between a very low 800rpm and 1500. And the idle is sometimes pretty low with the aircon going, as low as 450rpm in drive.

When in overdrive you should sit on about 1500rpm at 60kph with the overdrive on, without overdrive it should be about 2000rpm. Some times when you give the car a gutful and take your foot of the throttle the revs can drop to almost idle.
does the car struggle at 60kph?
has the idles speed been adjusted recently?
