whoosh/possible rattle when flooring

[Fash]

Don't know whether this is anything to worry about or not as the car's pretty much done this since I got it in October.

When flooring the accelerator hard and foot to the floor I sometimes get a whoosh/rattling noise. Only seems to do it if I floor the car and doesn't do it all the time. If I accelerate quite hard but not like I've got a lead foot it doesn't seem to do it (although of course it takes longer to get to speed). Took my mechanic for a spin the other week and he couldn't seem to hear the noise I was talking about. Car does have the airbox mod so was maybe wondering if that sucking in more air quicker into the tb could be the cause ? Not really sure tbh andit doesn't affect the acceleration or overall power.
Wonder if anyone else has had a similar problem ?
Thanks, Steve

Have you got the trumpet to put back in the airbox to try it and see if it makes a difference ? Mine wasn't in the airbox when I got the car so I don't know any different lol. If you're ever in sunny Donny let me know and we can compare noises lol

Yeah man, you'll hear me coming! Been suggested to me it may be a hose. http://www.vectra-c.com/forum/showthread.php?t=108453
