It has already been answered twice... albiet broadly. Meth doesn't destroy rod bearings... the added power does. If you want to do it right, it will cost more. (i.e. stronger internals and a properly balanced set up and a proper tune)

Couple that with beating on the car with a few too many max blast runs... and the engine can go poof at any time... under a load or not.

I honestly want to know how is he a cheat? Mitsu offers the warranty and they have very often turn people down! I mean how many trannys have blown that they have not warrantied? when they should have?? Wouldnt that be considerd stealing from us the public??? Who pay thousands of dollars just to watch the dealer stiff us???

Now granted a gt35r on stock block should void the warranty but how many people have been screwed with just a catback and a freakin intake?? So if he puts it back to stock and they warranty it I say good for him! Take it all day long cause you know the next poor shmo who trys to with stock everything is goin to get the shaft! They offer a warranty so they screw themselfs, but everyone knows its not worth a darn!

Another thing, this has nothing to do with insurance rates!!

To try to get this back ot, if you think a better quality meth kit would have saved this motor I think you would be completely wrong. A failure of the kit did not cause this motors failure, possibly meth causes premature bearing wear but there is no kit on the market that would be able to safeguard against that.

Yes and no, with alky/water, when the w2f (water to fuel) ratio is tuned right it can actualy promote engine life. Some people will just inject alky/water thinkin wow im doing good without knowing the harm, I was one too!

I got the Aquamist 2d system now because it has the perfect w2f ratio all the time so your not poorin in more alky/water than is needed and has no "water log" effects aka beating the snot out of the bearings.

Also the added power is a strain on the stock internals it will be intresting to see how long these ix motors will last with the one less piston ring.

I'll explain then. (Sorry to take this off topic) The reason we have problems with warranties is because of guys like him!!! Mitsubishi has all kinds of issues with Evo's because they are modified 95% of the time, things are pushed past their design limits... way past, and then these wise guys will come to Mitsubishi for warranty work saying that "uhh, my car was stock when I threw a piston through the engine block and into the asphalt.... derr, I demand a new engine".

It doesn't take a genious to figure out this scam. Come on man, get with it.

If you were the owner of a business that sold $200 chairs... and people were using those chairs to (for some reason) hold up cars instead of their designed purpose of holding normal people... and then those consumers were coming back to you with smashed up chairs demanding new ones... you'd have to make a determination.

You would ask, "how the hell did you do that". The crooked asses would then say "uh, I was just sitting in it and it broke. Give me a new one". You would look at the chair and note the tread marks on the cushoins, dirt on the bottom, scratch marks, paint chips.... and things wouldn't add up.

After a while of shelling out free chairs... you wouldn't be making much money. You'd be running a failed business and you would be loosing money. You would be sceptical of your buyers... even if you once were a trusting kind of guy. Fact is, the world is made up of liars and cheats. Why the hell do you have a lock on your car or home? Because even though you wouln't think that someone would steal or vandelize your stuff... some slimeball will take advantage of you in a heartbeat.

I really have not seen evidence to support what you say...then again can't really say I've been looking. What I do know is personal experience runnng my SMC kit for 10K miles @27psi. I could'nt agree more on the promoting of engine life, My motor would most likely be pretty lifeless after a couple pulls in my current tune alky-less.

Ok I gotcha and see what your saying... With that kinda situation If they have that kinda money to mod the hell out of their car why not just spend the money on a full build... Then they wont have to ever worry about it being to much of a "load" on the stocker...

But most will agree that its guys like us that do get screwed at the stealership cause they just "choose" not to warranty our cars even tho some of us take better care than those with bmw's/benz!!!! Its not fair any way you look at it, cause like you said the world is made up of liars and cheats, do we have the integrity to be better??? Id say let em do it cause they will do it either way just when time comes for you to make that choice be a good example.

Could the unburnt Meth be acting like solvent in your engine diluting your oil, thereby not lubricating your bearings?

No it would have to get down there... The quantity of water will largely depending on the following factors:

"1. effective cmpressure ratio
2. fuel grade
3. egt
4. knock tendency
5. ambient temperature
6. final charge temperature
7. a/f ratio
8. how close you run your engine towards MBT timing

Most factory produced car will have all the above variables under control. As soon as you start to modify your engine - you will notice a few of the above variables will change - but if it is inside the safe-operating area of the ECU, minor adjustment to the fuel, timing etc will keep the engine safe.

Most factory fitted ECU employs the following procedure strategy to keep the engine alive with the following balancing act:

1) retard timing with mild knock (knock sensor)
2) Increase air/fuel and timimng with heavy knock.

It normally works very well until you iincease the boost pressure, the excess fuel used to cool the engine is now being uswed for power.

Under this circumstances - you must replenish the engine's cooling capability by either using bigger injectors or water injection. Since water has six times the latent heat of fuel, you need to dump six litres of fuel per litre of water!

Since un-burnt fuel has huge impact on the combustion process, it robs huge amount of power if it is used as a coolant rather than as a fuel. In comparison, the OH radicals within water enhances the burn process.
(please read turboice's WI paper)

At last you question as to how mush water to inject ? the sweeping conclusion and simplied - around 10-15% w/f ratio when you are running a few psi over the stock boost.

Quite easy to calculate: add all your injectors flowrate together and multiple it by 10% or 15% - look at the aquamist jet size/flow, that is it!





It is clear that WI injectionf"
Thats why w2f ratio is so important. Thats why progressive kits are getting so big!

Cool mang. Oh don't get me wrong... I mod my cars as soon as I get my hands on them. Daddy doesn't like stock power. But I do get slightly irritated when I see others get screwed over by dealerships over silly things... all because the dealerships have become a bit sceptical and over protective about their warranty claims... all because of some shady characters in the past. That said, businesses do factor these accepted losses... just think about how many things have been stolen from hardware stores like Home Depot and Lowes. They know that they will be loosing revenue due to crooks... they know there are theives that come in and it sucks. Result... higher costs to offset the cost of added security measures and the losses they accumulate.

Myself, I have never had a problem with warranty claims... I don't make any bones about what I've done when I go for some work. It seems like they appreciate it when a guy like me doesn't try to lie to them. My full exhaust says on and I run an Ecutek flash done by Shiv on both my WRX and Evo. That said, I only run clean mods... I don't run MBC's, Typhoon intakes, BOV's, etc. I just run full exhausts, upgraded clutches, and a custom tune done by a top notch tuner. For some reason, it has worked without any hitches for me.

Now that's just plain retarded. Are you serious? What was their excuse for not fixing that? Have they ever heard of the Magny-Mosserman Act? (or whatever the case names were) They have no reason to deny a claim unless something was directly attributed to the other's failure... like if you put in an aftermarket set of carbon fiber doors on it with lexan windows.

If they denied your claim because of an exhaust, then it's not directly related to its subsequent failure... unless you actually routed your exhaust through your door frame. There's got to me more to this with your situation.

what does it matter. mitshi dealer ships have so much money do u really think it bothers them to put a new motor in yes it might bother them but who cares with the money they have. w.e i mean if that was my sitiuation i would probably do the same thing.
