Brake torqueing - Press the brake down hard, then you rev the motor up while still in place and then suddenly release the brake and then off you go..... Not recommended....
First off - If you get a spinout in your stock SC your tires are bald and the road is wet, and it is only one rear wheel spinning and not both... No seriously, first off you are only getting power to one rear wheel via the open end stock differential, the stock tires are skinny, maybe the ground or your tires are slick. That is the only way I can see an SC400 breaking loose out of the gates...
From a dead stop, when you floor the SC4's they simply do not jump out of the gates... That is fact... I would be very suprised if I ever saw a stock SC do a wheel spin from a dead stop "both wheels"...Not going to happen, sorry fellas...
With my torque converter and Supra Limited slip different (traction to both rear wheels) and my fat rear tires from launch, both rears skreetch out of the gates, the front end lifts a bit and I get thrust back into the seat...No nitrous either... That is what the Dragon Torque Converter did for me..
With the 100whp Nitrous system activated and from a dead stop I can peal out for half a block, and that is thru both 1rst and 2nd gears then in third I cherp and finally grip.... That is major wheel spin not to brag... With that being said I never hit the NOS in first gear because the torque converter is sufficient enough to take care of my 1rst gear speed and take offs...
