Okay, then let's settle the root of the argument. I have a type SH with a supercharger putting down roughly 250whp (dynoed at 230whp, but have done exhaust mods and the belt was slipping to 5psi tops on dyno day anyway). I have torque steer, alot. I found that the ATTS system acts a little bit like an LSD but have no scientific evidence showing that. The only evidence I have is how I did a small burnout in the parking lot of a wal-mart and noticed how I left two strips of rubber on the pavement. I got out and examined them. The drivers side strip started 1 foot after the passengers side and also the drivers side strip ended a couple feet sooner before the passengers side did.
But torque steer is still there.
No suspension modification can aleviate torque steer in a front wheel drive car. Car companies try to manage torque steer through suspension design, limited slip differentials, equal length axles, stiffer suspension mounts and vehicle electronics that cut throttle input. The MazdaSpeed3 and Dodge Caliber SRT4 are both good examples of how much thought went into controlling torque steer but it still existed.
I don't care how many articles or PDF Files you dug up on how ATTS works, I'm telling you that ATTS exists because front wheel drive cars usually tend to understeer through hard and fast corners. ATTS will provide the engine power delivery to go to the outside wheel of a turn which alleviates understeer and even makes the car oversteer. I experienced this several times before having to disconnect the electronics to the ATTS, where I would gun it, turn the wheel and the car's rear end would gradually start coming around while the front moved relatively little. ATTS limited me from doing a full donut in the car, but I could make the car twist 90 degrees from where I started.
I don't know why the article that dontbuyprelude kept talking about how ATTS eliminates torque steer through a corner, I honestly believe that this instruction manual was originally in Japanese and then was translated into English. I don't notice the word "understeer" used, so I'm thinking the translator thought that understeer and torque steer was the same thing.
In conclusion, the only person who can adequately prove if
ATTS truly does eliminate "torque steer" is a person with a JRSC using stock Jackson Racing electonics to keep the ATTS on. I am telling you that with my ATTS off, and the power levels I'm making, that the type SH suspension in and of itself does not eliminate torque steer.
