Euro loosing power

**conroe** · 24-12-2006 06:14 PM

My car tend to be slugish during the hot weather, not helping the fact that I have an auto. Does anyone else have the same problem?

do u have a after-market intake?
could it be the hot air from the weather??

Nothing is modified. It's all stock standard. I believe it's the hot air. When the climate is cool and humid or during winter, the car feels responsive.

But there is a definite difference and in no small amount. Especially off the line with the a/c running.

All cars lose power and become less responsive in hot weather. Cold air is more densely populated. A cold air intake kit can help in this regard because you will be feeding the engine cold air outside the hot engine bay.

^^^ does hot weather makes teh car use up more petrol aswell?

I think you'll find you have ya air con more which is why it's uses more fuel in summer.

Of course. It's a doubled effect when hot.

1st, hot air is less dense, so the engine injects less petrol. Less intake charge means a less powerful combustion.

2nd, when it is hot, your A/C compressor is running for a longer proportion of time to keep the cabin cool. So you would lose power there.

My euro always drove like a slug in hot summer's..

tho.. i found that using slightly different fuel helped in the summer.. that's when i switch from Shell Vpower to Caltex Vortex 98. It feels smoother and psychologically it makes me think it's running better

yeah.. i think this was covered lightly before a while ago in an old thread.
it seems to be slightly noticeable with sluggishness in hot weather..

its worse when u have a CAI
i have been noticing a loss in power too.. i put it down to the hot weather, at night it gets slightly better but because in sydney these few days its been humid i havent had too much fun.

all good though, double demerits

totally agree with aaronng. on both counts,
