TCS and launch

Vehicle: 2001 GP GT
Debate: First of all, I know the GT traction system is different from actual TCS, but I can't remember what it's actually referred to as, so I'll call it TCS for arguments sake. Anyway, concerning trying to get a quick launch:

Argument A) TCS should be switched off so that, when the tires stop spinning and actually grip, the transmission is delivering max power...

or:

Argument B) TCS should be left on so that the tire spin will be minimal and begin delivering max power sooner....

I am assuming that the GT traction system limits power to the tires which are spinning, if I'm wrong the argument may be a moot point anyway.

Also, I've heard of people fabricating custom intakes for the GT, wondering if there was a page where the process was explained/displayed.

This forum is so rad...

The TCS is designed so that when the computer sees one wheel spinning faster then the other one it will pull timing and your car will bog.
So it's not limiting the power to the wheel its limiting the power to the engine.

I'll have to go with Argument A on this one. I usually pull the fuse when at the track. You just have to learn the traction limits for your car with x mods at x track.

Do you have an owners manual with your car because if you read it you will get the right answer to your traction question. Your system is design to work in this order.
1. Retard engine timing.
2. if timing isn't enough it will shut off up to 3 cylinders to reduce power.
3. Last thing the car will do is apply the brakes to limit slip.

Well, I do have a manual although I can't locate the information you provided. Plus, the manual was written for the people who use the GP for a family car, not for people who take needless exits late at night just to come to a complete stop and then launch back down the onramp. Not that I ever do that personally, but if I did it would be fun to floor it 0-90 downhill and not worry too much about cops. haha

On a side note, thanks to everyone who posts in the GP forum. I like Nissans and Toyotas and Hondas but those who post on those forums are NOWHERE near as helpful as everyone in the GP forums. I've replaced my brake calipers and pads, removed my throttle body screen and disabled my DRLs, all with advice from you guys. Thanks again.
