Loud whistle when vtech enguages

[JustinTypeS]

Hi just today my car has started making a loud whistle sound whenever vtech enguages it doesn't happen on the lead up on the rev range just when vtech enguages

That's the VTEC blow off valve

Did you do anything to the car when the noise started? Check the intake pipe and or airbox for any leaks

Na not really just went to take off hard and it was whistling but only starts about 6krpm whilst acellerateing hard.so I can't hunt the sound down as it only makes the sound in vtech and the the type S won't enguage it unless the cars mobile... I'll take another look when the Suns back up

Id say the noise is most likely intake related...
