Here's the video (discussed above - around 2:30):

This smells of truth.

 

thanks for the video.

 

Cool video's. That engine makes the the 4G63 really look like the dinosaur that it is.

 

the reason why they used the belt to begin with was for the noise of the timing chain. but for longevity, I would prefer the chain versus the belt. most maintenance booklet will just advise you to check the belt but never replace it because it can last the life of the engine-like 300k miles? So, although all mitsu engines before the belt came with a chain, it just going back full circle and using the chain nowadays!(my A076 lancer had a chain)

 

Sounds like they are saying don't be a moron and erase the values. Does this also mean that anytime you disconnect your battery that the learned values are lost?

 

belt driven systems are generally heavier and have more rotating mass because the sprockets are very wide vs. the chains thinner sprockets. most people i have encountered as well as me know for high rev applications that the chains were generally used more. i race quads on my spare time as well as build them and it would be death to put a belt on a engine that revs to 12,000-13,000 rpms, lol. i see no problem with the design and i think its a better system than the 4g63 belt.

 

One of my friends said the same thing, almost word for word. lol

 

No, the values are not lost. Similar to the fact that your over all ECU map isnt lost either. Very few items actually get lost in a power outage event.

 

Sorry, not buying it.

You know how many times people over-react to things that are supposedly "said" by the dealerships!!! It's getting rediculous... And many times they have had NO EXPERIENCE WHATSOEVER with working on the problem. They just "heard of it" happening to someone somewhere.....like the lock ness monster.

Unless it starts happening to all of our Evo's I am not worried out it one bit. Give me the chain.....

And then why would you NOT BUY your car because they said this??? It makes no sense!!! Did they actually have to work on the car because they are all failing? I highly doubt it. So before you believe them like Moses, why not have them show you proof this is happening?

It's like the other guy on here who won't buy the X yet because the SAWC system isn't perfect. And he is waiting for an update for it. Give me a break....

Sorry for the rant. Just tired of people making decisions on things that people "heard" were happening or are true, but with no proof.

 

Yea, they are sending the techs to class because they don't have a f'n clue on how to adjust/fix a timing chain. THAT is why they are going. NOT because something is wrong with the car!!!!!!!!!!!!!!!!!!!!!!!

 

I would have to disagree with you there. If a timing chain is not good for performance then why do high end cars uses chains and muscle cars like the Mustang and camaro and even corevette for over 40 years? I owned many muscle cars over the years and from working on Hondas and other imports I much rather have a timing chain. There is reason why Honda went to timing chain and now mitsu switched to. From what I know about the timing belt on my Honda that it would easily break especially being boosted I had nothing but timing belt issues until I decided to convert it to Manual Tensioner on my car vs. the Auto tensioner that was common on Hondas befor 2002.

 

some of those cars you mentioned, still running on 2 valves etc.

But as i said both has advantage and disadvantage. The belt is more popular today. The belts are much better today then 10 years ago, and even back then, most car makers build the engine with belt.
Some companies using timing gears, all this is about preference.
My impression is, for racing the belts are a better option. I can be wrong very easy, since I'm not a mechanic. I'm just a user

For me just kinda interesting, why exactly they did go back to the chain. Specially when you need to replace an other one, if you change that. Looks to me the whole deal is more complicated. The video made me even more curious about that.
If all 4B11 engine got chain ,i think there is the answer. Makes the cost low. I would agree the Chain is better for DD. So if the majority 4B11 engine is a DD ,they don't want to develop an other belt system only for the Evo./money saving/ ?

 

what the race quads has to do with the 4B11?

i know little bit about rally , and those cars using timing belt .All of them. So maybe my back ground is ,makes me think the belt better.
Well the near future will tell, the chain was a better idea or not, i'm sure. I'm absolutely not saying is a bad idea ,i'm just wondering why they did it.

 

I've been involved with some pretty competent professional racing teams, including crewing for teams that won the LM 24hrs. I can tell you without ANY hesitation not one, not a single engine I have encountered in professional racing has used a belt. Almost all use chains, some used gears but NONE belts. Perhaps AUDI, Porsche, BMW, Ferrari and so on could use your expertise as they are always looking for an edge. Now at the local amateur ranks, people are STUCK with what they have so who knows what they would run IF they could.
