Now this is probably just a silly idea but I thought I would see what other people think of it.

Would it be beneficial to run your air conditioner (assuming it is still installed) while sitting at the line using launch control to increase the load on the engine which in turn might help spool the turbo a bit? I know the gains would be minimal but maybe it could be used in conjunction with a higher electrical load to provide even more resistance and then have the ac shut off as soon as the clutch is let out using a logic switch like we find in the keydiver chips.

I can see a few benefits to this sort of setup,

1. Increased load on the engine without increasing the immediate power to the ground would help spool the turbo without sacrificing traction and without the damaging effects of anti-lag.

2. With some fine tuning this could help maintain traction immediately after the launch for fwd cars or cars with street tires and then create a more immediate jump in power once the car is out of danger in regards to spinning.

3. The driver could end up perspiring less.

There are also some potential disadvantages,

1. I have no idea how long it takes for the load that the ac puts on the engine to fully be disengaged so it might hurt power more than help it and destroy your 60' time.

2. More heavily built cars could heatsoak at the line.

3. This would only benefit casual-hobbyist racers since they are the only ones who would still have an ac on their cars in the first place.

4. Implementing this for automatic transmission vehicles would be especially useful but probably more difficult.

5. Someone will probably call me an idiot


So there we go, lets have a discussion. It is entirely possible that this sort of idea is pretty pointless but so far I haven't been able to positively prove that to myself so I thought I might as well ask other people for their opinions.

Sorry but I leave with full boost by brake boosting. Automatic transmissions have the ability to build boost on the line.

But the ac perspires, and it will drop onto the track. This could lead to people's death.
