Down on power

[Master flex 87]

Just took the old girl out for a belt and let her warm up for a good 15-20 mins. Found a decent road and commenced thrashing it. 

 

It was taking taking a long time to climb up the ranges and lift engaged but not as aggressive. 

 

My heart was breaking, the (already non-existant) torque was pitiful and it felt like it had just eaten a large kebab. Even my missus commented on the amount of noise it was making, but it wasn't going anywhere... and then I spotted the A/C was turned on.

 

Turned that little anus off and she suddenly deposited the kebab and became sharp and responsive again.  I couldn't believe how much additional power it consumes with that on. Is it normal ? I know the A/C draws a load, but the difference was insane; but should it affect performance that much?

It definitely takes a big strain on the engine, my old 140 it was my summer turbo button

I can’t remember if it was as bad as that with my T sport mate, but it was noticeable, 

And very noticeable with a unmentionable (in this section) V6 I had..........I referred to it as my air brake 

I haven’t tried it with the 140 yet.......I’ll let you know in July

Haha I love this. Keep it on and then hit the 'sport button' 

 

Wolfie I will have a browse through your profile to find the V6. It's a terrible button.

I have this problem when I hit the windscreen defrost in the st, 20 mins later the mpg’s down to 30mpg and I realise. I can’t have I’ve ever noticed it too much in the celica, I normally only use it for the first few second to demismt or cool the car then it’s windows open and sunroof open!

I like to refer to it as the minus 20 button, good for reducing temps by 20 degrees but also take away 20 bhp lol

Fiesta used to take a big hit in power when front and rear windscreen demisters are turned on. With grounding kit added the hit is noticeably reduced.

Wonder if thats linked to the filaments in the screens on them ? Seems strange even at that still.

Front screen demister on fiesta is electronic style like the rears on cars but its got hundreds of those thin lines across the screen. Think the relay for the front one is 50amps.

It is a cracking system mind you. Do they own the patent to them ?

Yes, but that patent has long expired, Belinda

Damn. I thought 24 hours would have been long enough for you to forget...
