    Default flood water and air intake

    Hi guys,

    Another strange question... anyone ventured into flood water with their VXR?

    The road down the road from us often has water 6-12 inches deep after heavy rain.

    I've been desperately avoiding it after rain, but thought I'd ask others thoughts on how well the astra will cope? 6 inches must be safe, but with a turbo I'm paranoid!

    Tonight I tried to find where the actual air intake feed come is, but with the winter darkness it was far too hard to tell. Is it in behind the front V grill?

    Not sure I get it - do you mean behind the 'normally silver' V section (which is body coloured on VXR's)?

    If so then it's probably high enough for low water... but I think I'll keep doing the long detour for anything else (I'm used to it as our other cars intake is also a little low)

    Woah - thats well hidden! Hmmm, time for me to use the search button to find out about intake options then ;-). Thanks Ben!

    Anyone actually had to take their car though water?

    Just to let you know, I went through about 6-8 inches of water in my Zafira and it packed up the other side of the puddle!!
    I did all the right things, high revs and low speed as the end of my road always floods in heavy rain. All previous cars have gone through, no problem.

    Vauxhall had it for about 7-10 days and said that the water was everywhere, turbo, exhaust, sump, just about everywhere!!

    Luckily the insurance paid for the damage and all I had to pay was my £100 deposit

    Bugger!

    I would have thought keeping the revs around 2.5-3K would be best as it's high enough not to stall, but low enough that the turbo isn't just going to suck up water like a vacuum? Never really thought about the best tactic for deep water in a turbo vs. N.A. before.

    Took my VXR through 2 floods on Friday night, was at least 6" deep, well up to the numberplate. Went through fine. 1st gear revs up no problem.

    My washer bottle pump blew a fuse, but now fixed
