More Bhp From Air Con Removal?

[barmyscotty]

hi all i have a 1994 st205 gt4 3sgte. i have heard i can gain roughly about 15bhp from removing my air conditioning is this true. if so how much gain would i get. could i just cut the air con belt or is there an air con unit i have to remove to get full gains and how hard a job is this. has anyone done this who could guide me please. thank you all

There's hardly any difference at all on a modern vehicle, the air con pumps are fairly high efficiency and only a small amount of power is required to do the task at hand (as a percentage of cruise power output) so I'd not expect much more than 1mpg difference on a relatively modern mid-sized car.

It should be approximately the same fuel use on any vehicle (roughly the same air con requirements per car except maybe some really small cars) so the % may seem larger on super mini type vehicles (i.e. 2 ml extra per mile is a lot more % wise to a car that only uses 50 for motive power over one that uses 200).

You would save weight if you took the aircon unit out but is it worth it, only you can decide.

If you leave it in the just don't turn it on.
