I'm leaning on getting the RS in a few months. If I drag race the car will the front LSD puke on me? and at what power levels will it fail?

maybe it'll be better to get the regular evo with the regular diff?

 

Do not buy the car if you intend to drag race. Something will break, and mitsu will not cover it. RS or not, something will go with hard launches.

 

why not buy for drag racing?? cheaper, no wing, lighter, etc....

 

Because the Evo is not a drag car. This has been proven time and time again. The Evo is about handling, not straight line pissing matches. Yes, the Evo can be used as a drag car, and awd driven correctly provides killer holeshots. But its only a matter of time before the clutch will surrender. (Or worse, more expensive driveline components..)

Im not saying people shouldnt drag their Evos, but I am saying its not the purpose of the car. Good luck either way.....

 

dude, the evo is a great drag car, any car will break something if you drag it. the only rule to racing-- if you don't break something ya ain't going fast enough.

 

The evo is not a great drag car. If you’re talking about once in a blue moon, then that’s fine, but to buy it for the sole purpose of being able to drag it is not wise. If dragging is what your after, buy an 04 cobra.

 

Why are so many fixated on drag racing and straight line speed? This car is about the driving experience along with massive power. Like the above have said, it can handle some dragging before something breaks and has killer launches. Start saving for an aftermarket clutch or have one sitting around.

If you are only interested in dragging and don't care so much about handling, look at the SRT-4. 10K cheaper and can be factory upgraded. It will handle launches better due to wheelspin and you will have plenty of money left over for mods. It can be made super fast.

 

still won't launch like a evo. besides in the U.S. road racing comes secondary to drag racing. personally I perfer road racing, but facts are facts. How many people will ever road race, or even auto cross their evo? compare that to the average joe who will at least beat down on teh evo at a stop light battle. not saying I condone it, but it's is just the facts of life. any way, the evo still makes a great drag car, espically in the street tire catagory. just ask all the f-bodys and mustangs, and damn near anything else for that matter. IMO buy it drive it, race it, break it and fix it.

 

Before you totally flame this guy there is a good point to be made. When will the RS diff brake? I have heard of some of the UK crowed braking diffs and they are not using them for dragging! But I agree, Evo not intended for the strip!

 

any diff will break with abuse, a ford 9 in ch rear will break, a dana 60 will break, thei is why aftermarket parts are made.


what factory car is designed to drag. lets see,

lt1, ls1 F-body- 7.5 in rear gear known to break like glass-guess not

Corvette- IRS rear, trash clutch, auto 2200 stall- guess not

Mustang- 8.8 rear-strong, BUT a truley trash transmission- guess not

SVT Cobra- IRS rear and a truley trash tranny, known to also break like glass, guess not

E46 M3- motor blows up, and breaks parts like crazy, definately not!

well aint to much left now. the bottom line is none of these vehicles were designed for drag racing, or road racing, or autocross. Hence the AFTER MARKET, they are designed to be street driven vehicles with the appearence of race cars. so in short they are all built to the lowest bidder standards, none of them are truely "factory race cars". if so, they would not have these major weak links. so back to my original statement -------------race it ,break it, fix it

as far as flames go bring it on.

 

Well, most of the stuff that you said is correct (I think, I’m not that up to date with the American stuff), except the Evo. The RS (which diff the original post was about) was designed as a race car, a rally car to be precise. That is the reason for the rather lack lusted interior, the lack of sound deadening, the mechanical diffs, and no ABS. This was because the last thing a rally team (be it rallying on tarmac or gravel) wanted to do was buy an expensive motor with loads of frilly things in just to rip them all out. So Mitsubishi built them a cheap car so they didn’t have to. They also made the car stronger, so that it lasted on the tough stages longer. So the original question stands how long will the RS diff last?

 

I agree with you to a point, If the Evo was really designed as a rally race car, even the diff would have to be up to race car specs.
because rally cars race on tarmac also. which requires much more demanding issues from the diff- front, middle, and rear.

True rally cars have to replace diffs ALL THE TIME, which means, IMO- race it break it Fix it.

I think we are basicly saying the same thing, if you drag the evo eventually it will break.

 

"EVO 8 RS LSD, when will it break" aynthing will break where its raodracing , dragracing , street.... or what ever if your beat the **** out of it. Think we need to start looking why things are breaking , not where we were at . "I" think its b/c alot of ppl dont now about wheel hoop and how bad that is for your car!!

 

Any car you race will break period!
Its just a matter of time, I don't care what model, brand, etc.
I've drag race my EVO many times and killed many rear wheel drive V8s.
Pick a car you like, you know the risks. Hey look at the pros, they have a team of mechanics around them to fix the **** they break.
Bottom line, with speed you sacrifice reliability.

RACE IT --- BREAK IT --- FIX IT

 

If the diff in the RS is the same diff that Mitsubishi has used in the Evo in the past, the issue will be that the bolts that hold the diff case halves together will shear. The cure is to remove the diff and use grade 12.9 hardware. The new bolts should be loc-tited in place. The bolts are available on the Lancer Register website in the UK.
