Hissing sound coming on/off boost stock FG

[billyonesbay]

Hi,

 

Stock FG making a hissing sound only as the turbo is coming on/off boost and only while the car is warmup up.

 

If it was a constant issue I'd be looking in to leaks somewhere but the fact that it only happens for the first 10ish minutes of driving and at no point does the car have an issues making boost makes me worried it's something potentially worse.

 

Have some mods planned and just wanted to see if anyone has heard of something similar before I go forward and potentially blow something up,

Thanks.

Probably just a minor air leak... but the way you've described it doesn't sound like anything really nefarious anyway, so I'd just get it checked over for a leak if you're not confident in finding it yourself, definitely worth ensuring the car is mechanically A-OK before starting the modifications, anyway.
