lol!!

 

hhaha we'll call it something else tomorrow

 

how about the weight gain

 

How about the benefits of AYC vs a mechanical rear LSD! Improved function vs. stability, consistency, reliability, and weight! There's a reason it gets swapped out/doesn't come in RS's. Also, with any ACD reflash, including Gruppe-S's that will come out for the X, AYC function is disabled...

hehe found this in another forum:

To a degree it is a drop in solution if you use all the parts from the RS motorsport version.

Yes, we do this all the time since we sell the RS in a motorsport application, so we know what needs to converted from a GSR to an RS LSD.

The benefits is firstly strength and from a driving benefit or perspective (or benefit) it means that in a high speed corner like a big sweeper you dont have the AYC 'working' hard and giving you that wild ride wanting to spit you off the track. Again, this phenomenon you will only see in a motorsport application, if it's purley a road car that see's occasional track usage I wouldnt recommend it as it's expensive. However if your Evo X is used for a lot of motorsport and you've found the limit of the AYC and what to move forward then, YES this option is for you. But only if you are finding the limit of the AYC from a driving perspective, from a strength perspective particularly in the 5 speed manuals I'd recommend doing the Front Ralliart Supertraction diff first as this will elliminate most of the damage of munching your Centre diff when you are talking about serious Torque.

Roughly the RS rear diff conversion is around 7K (AUD) in parts alone (consisting of around 42 individual factory parts to make iot all work) so you would want to be very commited to going down this path.

The upshot is if you have a similar powered car and driving ability to a friend with the same car, you will come away with a quicker car that is more stable in high speed corners and your laptimes will reflect this once this is done.

 

hmm i find this thread very interesting. It seems pretty well split. I sold my Evo 8 and miss the AWD so I think I am gonna go back to a Evo. Saturday I plan on driving a X and IX. I hope both will be an upgrade from the Evo8 and deals are kind of swaying me towards the X. It seems to be the same price range as alot of 06

 

that is all nice and great... but most of the evo in rally i know of, they running AYC with double pump. Solves all the problems...
That reminds me the NASA pen story
Although can be 100% true , we doesnt have any unusual problems over the mechanical dif. AYC Its heavier though. But in rally you have a minimum weight for car type so that is also not really matters.
I never had proble with AYC, so my friends in EU. After a little pump and support parts for the pump install.
My country we do it more simple way then change the whole rear for ...
My buddy with his "undergrade" AYC set up /oem/ won the WRC Catalunia rally 2009 Gruppe N category , over 10 sec with 20 sec penalty ... His debut in international rally .

KISS rule of thumb .

The AYC is a great unit and works extremely well. THe ACD you can rewrite it, or get a Ralliart ACD unit if you really want to spend money. But for what?
This type of stuff if became your problem, then you should be put over 50 grand in your car already, and fighting to get 0.010 sec faster from your previous time Untill then its not worth to mention it, sice many other place you can have more benefit for a same money and less work in your car.
The main reason is the AYC doesnt come on the base RS is money
The RS MR comes with AYC but that is not like the base RS which is comes with Lancer GST interior- GTS breaks- and without wing etc. Also the RS MR cost more.
The Base RS is comes a bare minimum, so you can immidiatly take it a part, and build a car from ground zero. The Base RS is also limited for 120mph for safety reasons....

 

The RS MR doesn't have the 120mph speed limit? Very very interesting. I wish we had the RS over here.

 

I said the same thing......until the test drive, two weeks later my 06' Evo IX (that had been through, 3 built motors and 2 stock blocks...all in 15k miles lol) MR was traded in on an 08' Evo X MR! I have no regrets, no second guesses...nada.

At the end of the day....haters will be haters. So it's ultimatly up to you. Personally I hated the **** out of the Evo X, and swore I'd never own one.
But during that test drive....something happens.

Evo X FTMFW!

Either way, I hope this helps you....good luck with your choice man!

 

I weighed my Evo X MR, at Evolution Dynamics, and she weighed in at 3406lbs. With full interior, spare, jack, lap-top, two suit cases ect. After my car came off, Richard from EvoD had to verify that the machine was working accuratly. He pulled onto the machine and weighed in at 3586lbs. Needless to say, lil buddy rich, and myself, were stupified as to why.

Later on a kid with a 4dr 335i, completly stock, happened to be at the shop. We decided to weigh him just for ***** n gigs. He weighed in at 3218!

 

All evo has 112mph (180km/h) speed limiter in Japan, as well as most other cars, it is not only the RS, or at least they did up to recently, same as '280ps (276bhp) gentlemen's agreement' power limit they had before, I believe the speed limit was set either legally or voluntarily.

335i sedan should weigh close to 3600lbs, coupe only 20-30lbs lighter, perhaps he was low on fuel and fluids and had spares out? 16 gallon fuel should be close to 140lbs, so he must have removed another 250lbs somewhere...

 

nope as far as i know only the base RS is limited, because the GTS parts on it, like brakes, rims tires, etc. so they decided for safety reason to limit the car for under 200 km/h that is might be less then 120 mph, so i just put it up as an aporx. /close/ number.
Why 200 km/h? Mainly because the tires witch comes with. You can't sell a car which goes faster then a tires can hold. Just a regulation.

 

Well I hope that is what happens to me. I dont hear alot about Transfercases and bad syncros on the New Evo X. I hope that is because there arent many/ or any. Even though its a new platform and many bugs havent been completely figured out. My main problem with the 8 was the Unreliability. It will be my DD and I will lightly Mod it. But I cant afford to drop 2g on a transfer case right away. Or rebuild an engine everytime it breaks. So I am really leaning towards the X

 

I agree completely! This Evo handles so much better than my VIII and IX did.

I think people need a lot of time both SAYC and non cars really compare them. I'm not saying kyooch has SAYC envy, I'm saying he does not have it, thereby he has chosen to hate it.

Kyooch, if you stopped reposting stuff off the internet (especially companies that are trying to sell a service) about why the SAYC is not as good and choose to tell us from your driving experience, it would be a lot more meaningful. There are too many winning cars using SAYC to refute its usefulness.

There is no way in heck I would pull mine and replace it with a mechanical diff and ACD reporgram. Asinine. If my IX was a non-US neutered car, I would have it still, 100%.

 

untrue - while I have experienced the X's sayc (in auto-x, though admittedly not a LOT of time, it was in a high performance driving setting), you've stated from before that you haven't experienced a 9 with an upgraded rear diff. The difference is huge. You can get on the throttle so much quicker/apply throttle than with a stock 9 rear diff - I barely notice a rear diff even working in the stock car. The stock 9 exhibits a lot of understeer mid corner - it's mitigated by a few mods, but that character will not completely go away until a more effective rear diff is added.

I'm not saying SAYC is bad - it's better in fact - up to a point.. Most cars and most drivers will be better off with it, no question. Exactly how much better off is the question, compared to a mechanical rear diff. I've read (not experienced) that if you're not following the "correct" line the car determines based on the sensors and inputs used on the car, the SAYC will compensate and "help out" for you to follow that line. This is both great, and potentially a hindrance/inconsistent. I don't recall, didn't Gates swap out his? and the AMS TA car?

I'm not the only one saying it, and the products out there, sold or not are still out there and their results are shown, in both UK and Japan this is common. The US cars just happen not to have it anyway. All the ACD programs in EVERY country disable the AYC function.

But yea - I'm not saying it's worse.. I'm just saying, from experience, a mechanical will do 95% of what the SAYC will do - while being more consistent.

 

I think we just need to get kyooch in a X so he can feel it. We can read and speculate till the cows come home. kyooch, you may find that the AYC is exactly what you like. You may find it's not. But until then I just don't see how you can say it isn't for you.
