Well, you can go over 300HP without LSD and effectively no torque steer. GM did it here in the US with the 2006 Pontiac Grand Prix GXP. By stuffing the new 5.3L aluminum LS4 V8 under the hood, they managed to make a 303HP, 323lb-ft sport sedan, with front wheel drive.
According to the folks who have tested it in Car and Driver, Automobile, Road and Track, and Motor Trend, torque steer is minimal, if even there at all. GM managed to accomplish that task by actually making the front wheels larger than those on the rear (Bridgestone Potenza RE050As, 255/45-18 front, 225/50-18 rear). Pontiac said their goal was to be able to chase down the BMW 330il, and although it does it to some extent, it is still limited by the FWD setup.
...So, this leads me to my question... Are the front tires on the VXR bigger on the front than on the back?
