If you use a manual, have you tried launching in second gear? That really helps to control smoke on some cars. Taller gearing (numerically lower) ratios could help too, especially first gear. Just controlling the throttle can work too if you're not that bad at it. If all bets are off, just turn on TCS if you don't mind losing time on aid intervention (lol oxymoron). Just keep in mind that aids getting you way can cost some time. Although I don't use it much anymore, TCS on 1 can help on higher powered cars. Launching an 800 horsepower Speed 12 isn't easy, as it will fry its tires all the way through third gear.
And if you find you're winning too easily, just take off power. That could work even if you're not looking for a challenge.
