Mike Posted May 9, 2006 Share Posted May 9, 2006 or would it be cheaper than all that drag you'd create with the windows down?! Quote Link to comment Share on other sites More sharing options...

mattanna Posted May 9, 2006 Share Posted May 9, 2006 They can reduce bhp by 10-15bhp when on too and will take about another 5mpg too, i am the same, but was so hot today had it on, tight arsed bastard that i am? Matt Quote Link to comment Share on other sites More sharing options...
andrew7 Posted May 9, 2006 Share Posted May 9, 2006 I tend to turn on the A/C until the pipes are cold and then use just the fan until the pipes warm up again. Dunno whether this save gas or not but means I use the A/C pretty sparingly and still stay reasonably cool.... Quote Link to comment Share on other sites More sharing options...
imi Posted May 9, 2006 Share Posted May 9, 2006 didnt it potentially rob Dashrendar off 50bhp when his car was on the dyno with the AC on?? Quote Link to comment Share on other sites More sharing options...

Matt No way will it make 5mpg difference on a Supra. In fact I've never been able to spot any difference at all in fuel consumption or power. I mean some on, you're talking about a 320bhp car here, not a Micra! Quote Link to comment Share on other sites More sharing options...
michael Posted May 9, 2006 Share Posted May 9, 2006 Mine is on constantly - I'm at the temp I want to be, I'd prefer that to having 50p extra in my pocket each week. Quote Link to comment Share on other sites More sharing options...
Ewen Posted May 9, 2006 Share Posted May 9, 2006 I saw the Mythbusters episode mentioned above......at low speeds AC robs more mpg than having the windows open. higher speeds totherway round. By the by, anyone used one of those AC cleaning 'bombs' ? Are they as much fun as they sound ? Quote Link to comment Share on other sites More sharing options...
Hobgoblin Posted May 9, 2006 Share Posted May 9, 2006 But its great if you have to sit in traffic on a hot day, windows closed and cool as you like. I dont drive a Supra for the mpg, its purely a fun thing, and as such a few more quid doesnt really matter to me. Quote Link to comment Share on other sites More sharing options...
