The old rule of thumb was that the AC units dragged HP down by 30-20 hp. So my question is has anyone done this comparison ?
My 90hp VW Golf TDi had an excellent automatic climate control system and if at any time it required 20hp to operate I think I would have noticed it.laws of physics
20 HP = 14,920 Watts
14,920 / 3.412 = 4,372 BTU's
The Challenger needs about 15,000 BTU's to successfully cool the interior.
On the dyno, kill the AC
In my Scat Pack yesterday with the dyno display up. At 45mph engine HP read around 20. With A/C off no change. With A/C on and at max cool no change.It’s been pretty well discussed that the ac kicks off so unless you can figure out a way to over ride that it’s all a moot point.
