Do you have a link to anything from Mitsu that says the Evo is 50/50 all the time? I recall reading it is 100/0 .... which was disappointing. I thought torque steer was induced by FWD with a transverse-mounted engine and an inherent "feature" of that configuration.

 

I get it and its not that bad and only in first for a fraction of a second...its definetly there but hardly noticeable

 

I don't have it off the top of my head, but the actual article explaining ACD is posted on this site numerous times. Regardless, it's a widely-known and recognized fact that the Evo is ALWAYS 50/50. Not even the different ACD settings change that. By no means is it ever 100/0 - that's crazy talk.

 

Yes, thank you! Someone who agrees with me...

I need to find the source of that 100/0 info I read. I know I read it at the Subie dealership when I was cross-shopping the cars.... yep!

 

I wouldn't call that agreeing. He said it's very slight - you say the car goes straight to the right. He also is modded beyond 300whp/wtq, and you are stock.

Subies can adjust their torque split with FCCD or whatever it's called, but Evos can't.

 

Yep it's very slight but noticable when you are focused &/or sensitive like I am

I just looked up some stuff on google and the few articles I've found do say 50/50 torque distribution....

" In all driving conditions, the system starts with 50/50 front/back but can go to almost 100 percent front. The system can't direct any more than 50 percent of torque to the back, however."

it's still a bit vague (damned autojournalists)

I guess I just needed to vent. I finally found something to "not" like on my Evo. Otherwise, it's perfect.

 

I actually think something is wrong with it, because this is not normal, and I've never felt it at any power level with any tires and any suspension configuration. I've drag raced, autocrossed, road raced, rally raced, and lit 'em up countless times on the street, but I have never felt the slightest hint of torque steer. If it bothers you enough to make a thread, I figure it would be worth fixing.

It cannot go to 100% front. That journalist did not understand how it works.

 

wow...talk about fishing for compliments. lol great pic tho.

 

i think its partly due to the slight crest of the road that causes the evo to hang slightly left or right. thats the reason why on the track you dont have this issue.

this effect does have to do w/ FWD cars but its definetly not torque steer... but it is a good example a "flaw" in FWD cars (which evo acts like alot of times). drive one side of your evo through a puddle and your car will push to that direction. now do the same in a RWD car and it will be significantly less. this is the same idea when you step on it on the street. the slight imperfections of the road is getting accentuate by the power your putting down. now if you were in a torque rwd car (lets say a supra) u wouldnt get that 'tug' in your steering wheel to a direction but just lotsa spinning tires hehe.

 

^Good example. I have owned a high horsepower FWD vehicle, give a high whp FWD car full throttle in frst gear, that is torque steer, even with LSD. A stock Evo will not exibit torque steer on dry pavement, it just doesn't happen. If you, the original poster feel you have torque steer, you may want to find out if you have actual problems with the vehicle.

 

Well for one I dont mean to be mean but you are totally wrong. This is not a volkswagen R32 with Haldex that remains fwd until traction is needed. An evo has 50/50 torque bias and has been discussed hundreds of times and it cannot direct 100% to the front...whoever said that has no recollection on how the VCU works in the evo. It is damn near physically impossible for you to has torque steer...plain and simple. Take it from the people that have driven high horsepower evos or have greater knowledge about the evo drivetrain and dynamics. Something is wrong with your alignment or their is a hidden cause for your pull. I have owned high horsepower FWD cars and torquesteer will damn near rip the steering wheel out of your hand. I have been in stock, 300hp, 400hp, and other evo's none of which exhibited any torque steer so I cant see how yours would be an exception.

 

Geez with a car like that in your garage atleast you could clean it, box-o-rags, unfinished drywall? untinted garage windows wtf? I will take much better care of that Porsche, give it my address and I will let it right letters to you. please note my sig........



MMMMMMMM

 

Torque steer direction is dependent on many factors.

One is the type of dif you have. Since we have a torsen biasing gear pack lsd our spin ratio from tire to tire could be anything ie. 1:4, 1:3, 1:2. It depends where the geniuses decided to set public accepted limit of drive-ability. That means the wheel with slip will spin less than the wheel with grip. This is so your front end does not hop as you take a corner, because the inside wheel always spins less than the outside.

Two is how your diff is engaged, because ratio is always variable.

Three is how the surface of the pavement is in grip.

Four is how the diff tries to engage due to the changing grip in the pavement.

Five is the type of grip your tires has.

Put all that in your bowl and you have a real messy hash and add a few other variables and you will have touque biased spin. -J

BTW, there are many type of LSDs clutch pack, variable electronic lsd or Detroit locker style the ratio percentage and pavement grip factor all effect the way your car will pull.

 

That post was AWESOME in the way it fully explained the ACD and corresponding settings.......something to do with the amount of time the ACD either disengaged or engaged or something like that relative to the setting you have it on. The few times ive noticed some slight torque steer on my car was probably due to the fact of road irregularities like tracking in a lane etc. more than actual noticeable torque steer

 

There might be a problem with a suspension bushing/s in the front end. Causing it to do that.
