Should you do this? What's the silentshaft for?

--removed--

Hmm im thinking I will pass... Dont like the idea of putting the engine off balance

ermm...How does the rotating shaft reduce vibration? Does it reduce vibration by countering it with vibration (If it makes sense)? :?:

Anyway, how does it make the extra power? by having less drag on the belt?

The idea of having your engine unbalanced is VERY bad.

I dont approve of what you've done mate. It could be the start of many problems.

:?

You should be getting your motor balanced! Not unbalancing it.

The thing with a performance motor is everything works together, harmoniously.

You'd be better off getting it balanced and then getting stuff knife edged and lightened.

You're comprimising reliability for performance.

Seems Similar thing I did to my early TN motor when I had it turboed in my Sigma....
We removed the harmonic balancer and then had it ground down to a straight shaft. Plugged up the opening behind timing cover and all was well.
It allowed the motor to rev harder .... Im not sure on the "just remove the belt bit"
Will ask my mate the Mitsu mechanic ?
Ok just got of the phone....
The reason we did the above mod was, we were changing the crank from a 2l engine into the 2.6l motor (lowers compression for turbo charging) and the new 2.4l engine was then fully lightened and balanced.
Basicly what you have done is a VERY BAD idea and Id hope no one else try this. Your motor will vibrate it self to bits... you will get harmonic vibrations through the motor, crack engine mounts and exhaust headers.
Also I think from memory (I broke a timing belt on my TE 4cyl 2 weeks ago) that the second silentshaft is driven of the smae belt as the oil pump... so Id think twice before cutting it.
All I can say is good luck and I hope that it doesnt wreck you donk.
But I would say for others wishing to try this.... WAIT .... and see before you try it.

it is perfectly safe to remove ONLY ONE!!.. not the one on the oil pump, lots of cars donet even have a balence shaft,
its up to u i dont sugest removing it if you dont understand how it all workks..
i have had mine disconected for almost a year now. no problem what so ever,
with little to no money spend on my car it can almost out prefhorm a v6 magna,

the person who i was tlaking to about this idea is an automotive engeneer and is verry well respected, if it was bad he would not have touched it,
-pines

i would like to see a dyno sheet to prove that you have the power increase that your suggesting.. not that it would change my mind in cutting the belt, but to see if YOU have been deceived in thinking that it gives more power.

Allmost but not quite :badgrin: :badgrin: :badgrin:

everything is there for a reason...who told you about this mod?

--removed--

dyno dyno dyno.....it would be good to find out how much power it actually makes

hrm...
i cant aford a dyno :D
heheh!!

Whats the use of more power when the engine is now unstable? :roll:

More power, less power, faster, slower who cares when your engine is going to vibrate itself to death.

well the chics might like the vibration function ;) specially if its connected to the drive shaft, and the gearbox.. the gear stick might get a bit of action. ;)

wouldnt bother spending your $$$ on a dyno...but a new mechanic...Its sounds sus and very dodgy...was it done in bankstown? if so ill understand the logics totally!!!

To those outside of sydney, bankstown is where the lebanese live basically...i used to so it explains me sorta. Lebanese=dodgy...
I mean...who gave me a pink slip this yr? With a cracked rim, bald front tyres n a pod with dodgy looking mounts?

its not gowing to vibrate to death..
farC .... FIne JUST forget that i ****ing sayed / sugested that!

i withdraw my input...ffs.

thats it for shareing any of my info EVER,,

Just because people don't agree with you doesn't mean to say they are right.

I had a word with a mechanical engineer the other week and he said its was quite ok to do. However your motor will vibrate more. It doesn't make the motor unstable.

Hey man do be like that...
I cannot vouch for others here but... for me I was concerned of maybe or maybe not damage to your car... at the end of the day you have to go with peoples input from those you trust...(for you it is your dad and the other guy... for me it is a friend of mine who used to work for mitsubishi...)
And I know that my friend has suggested stuff to do in the past and we did it and otheres said we were crazy ... but it worked for us...
That said I say if it is working for you great and it is ideas like this that help make our cars better..
I asked my mate straigh away about doing this .. so it got us thinking about other ways of increasing power etc...
So I say keep up the good work and people can try or not try it if they want .. it is up to them.
Please keep putting in your imput .. I know I appreciate it anyway.
Oh and this is all in a non sexual man to man sort of thing and nothin gay about it... "not that there is anything wrong with that" :D

Pines;

It's good that u are sharing your mod tips with us. A forum is all about suggestions, rebuttals and contradictions. It's where we learn from each other and give opinions. It's not that WE all don't like the idea, we're just stating out concerns thats all... :)


Relax Pines... it's all cool ok? :)

yer man lighten up,

go get a bit of booya from ya girlfriend, and you should feel better.. ahhh, the stresses of modern day life...

a bit of 'booya' will fix that up mate.. try something new, pull a move off in the back seat of the 'pines apple' and see how ya go :badgrin: :badgrin: :badgrin:

may the force be with you :badgrin: ;)

Do you think you might take some pics of othe "moves"... for some of us no so lucky to see many moves these days? :lol:
no seriously ;)
Haydn

Haydn

ill try next time i get one in the back seat..

stay posted ;)

See this is why Im getting the cameras in the car ;)
Haydn

Well all I can say is that the Mitsubishi Engineers when they design these motors dont put bits in there for the hell of it.

Sorry Pines, I dont like what you've done, but you don't have to listen to me. And you shouldn't take offense, you can't please everyone all the time.

Just chill out.

See this is why Im getting the cameras in the car ;)
Haydn

i hope you get her consent, cos that illegal ;)

a bit like the pics ive been taking with my fone ;) hahah.. jokes..

ive never done anything illegal :D ive never sped, never done burnouts, never done any illegal mods to me car..
im ligit i tell ya 8)

mmmmhm....

no hard fellings. 8)

Aww.. What's this? I check the post about a week ago and ooh.. engine mod? With pictures? Ehy? 2 pages?! Hmm, must study for exams though.. *closes*

Come back and everything's gone and everyone's gone bonkers at each other... Well, not quite, but anyway..

/me shrugs.. Look at it this way Pines, you've done more than me... I read up a little on this stuff, but practically I've had next to no experience. Regardless of whether it provides a substantial gain or not, you're still one up on a few of us in experience who haven't had the guts to rip the engine apart..

Best part about doing something is not always the gains, but sometimes the experience...

that mod was only for the 4 cylder was never ment for the v6..

Anyone got a 4cyl magna manual... besides mine?
Haydn

Sure do, love the 2.4

Blakie is yours Manual?
I thought it was an auto?
anyway why dont you put a turbo on it?
Haydn

No its an auto, sorry i didn't read your post correctly.... woops.

If it was manual mine would have a whopping T28 with a nice shiny manifold running stupid boost instead of a bodykit.

I so wanted to turbo my little TE ... but then I got the V6 :(
I wish someone out there wanted a TE 4cyl manual and then wanted to turbo the sucker.. they are so easy to do it to :(
Haydn

I'll swap gearboxes with you and i'll do it :D

Serious to :D

That would be so nice, and the job would be so simple.

I did heaps of research on this, about a days worth cause pines really got me thinking, and yes I totally agree with what he has done, he has disabled only one of the shafts not the two, remember that the smaller mitsu engines only have one of these shafts not two, it is only the bigger four cylinder motors that have two balance shafts, it has been dyno proven that it gives back power that was lost in running the extra balance shaft, you remember they spin at exactly twice the engine rpm in the opposite direction and can weigh from 9 to 15 pounds in weight, do the math. And guess who invented the second balance shaft,,,,,Mitsubishi did.

And besides this is a public forum not a public flogging.
