Uh, fuel tuning? Don't just go increasing the boost without knowing what you're doing.

Also, don't expect much Ralliart development for awhile. The car is too new and it's going to live its life in the shadow of the Evo.

 

I think the RA will get a decent amount of support, it's just going to take some time to get there.

 

Please be technical with your advice and posts. What am I doing? Is this leaning it out? Creating unsafe boost to a specific component? Is the turbo only capable of devlierving X amount of boost and this mod is just holding the boost longer, what?

If we ( everyone on this forum ) know what Im doing then discuss the pros and cons. If we dont know what is going on then lets research and ask questions that stimulate others to join in and post useful information.

Here is an example: https://www.evolutionm.net/forums/sh...d.php?t=341540

 

You're adding more boost without the car knowing what to do. If you add more boost, you're adding more air thus making a leaner mixture. You have consider things like detonation as well. There's also the issue of moving the turbo out of its efficiency range, simply cranking the boost up isn't always the best thing to do.
Something to keep in mind, the Ralliart is still fundamentally different from the Evo X. The intercooler is different, the turbo is different and the piping is different. This presents a dilemma to tuners since if they make parts for the evo, they have two models to split it with, the MR and the GSR. If they make parts for the Ralliart, there is only the Ralliart. I think it is way too soon to say whether the Ralliart will be a major tuner hit.

 

I was thinking that since those parts are the ones that are different and not the actually motor / block that once you adapted to the exhaust ports and intake, everything else are the parts you wanted to upgrade anyway. Youve got an EVO building block to start from. Further more, there are dozens of tuner shops and turbos that could be incorporated into kits for bolt on power. Yes, No, Maybe?

What are your thoughts on the car's ECU able to make adjustments ( within limits ) to an increase in airflow and boost? As far as I can tell from the EVO post, screwing the arm 3 turns ups the boost approx. 2 psi. Could this be outside the realm of ECU's ability to adjust, or does it have limited / no ability for variance?

Note: they are testing a completely different turbo than the Ralliart's.

 

One thing that stuck in my mind when i bought mine is the sales manager told me the car is a parts bin, Meanning its uses parts from multiple vehicles, like the motor,exhaust,and tranny is from Evo 10, The brakes are off of outlander SUV, and the body parts, and suspension is a stiffer more sporty GTS suspension so mabye some possibilites there? Just a idea i had?

 

Something to keep in mind, the Ralliart is not an Evo, it was never intended to be an Evo. Somethings that could cause issues are the fuel injectors and the fuel pump as well as the presence or absence of brackets, how lines are run, etc.
Most ECUs cannot make adjustments to large increases in boost. You also have to keep in mind the ideal operating range for the turbo.

 

Chances are we'll be able to get away with boosting a couple more PSI, as most turbo ECU's will adjust for outside air conditions. But going past say 18-20 psi may cause the ECU to pull timing or any other way of protecting the engine mitsu has enabled.

 

I would recommend increasing the boost unless you can tune for it.

 

Anyone know the curb wieght of the Ralliart ?

The GSR weights in at 3517lbs, The MR at 3594lbs

 

3450, give or take.

 

Thanks for the info.

Is that the base or upgraded Recaro version ?

Also what stock AUTO_X class will this probably run in ?

 

For the Recaro package, add maybe 20 pounds for the sub. I can't imagine the seats are that much different weight-wise.

As for autocross...I expect it'll run in the "better upgrade the wheels and tires immediately" class, but that's just a hunch.

 

The cars are just hitting many dealerships now. Give it time.

 

I dont know what the hell Mitsubishi is thinking. But they are alittle bit lazy for not even putting the car on their Website for build and price. How could they get a decent amount of buyers.... I got disappointed on Mitsu lately! Come to even think I still love my old lancer. Most car companies have the new car on their website when they released a new model but not to mitsu.....
