How much power does Air Con reduce form the engine, i am putting a 20V in my rolla and it is under debate whether to put it in or not...Pending the power loss.... Also do the air cond belts slow the engine down alot or not affect it until the air con is on??
The air con will only drop power when it is running. From my expierence, when the A/C is off, the loss is so small you probably wouldn't notice it. The biggest disadvantege would be extra weight and the A/C radiator infront of the main radiator.
*shrug*
I'll be putting the A/C in with my 20V swap, but thats just me.
