Hi Guys

Car seams to have developed a small noise?

On boost a whistling noise starts and sounds like its coming from under the dash or inside the car somewhere.... or very close to it!...its almost a very loud tinitus

At first I thought it might be the vac hose on the boost gauge but I changed the gauge along with the vac hose and the sound is still there....Its all quiet before the boost gets above 0.5bar then the whistle/whine comes in.....I even checked for loose trims around the front in case it was that....there is no change in performance and she boosts right up to a smidge under 1.0bar..


Any ideas anyone cause its driving me mental!

 

Exhaust downpipe gasket leaking will cause this

 

Just an update to my whistle....

She's all sorted now....

A big shout out to the guys at Westaway Subaru Northants, they did a cracking job.... as always!!

Cheers guys....






P.S.... I promise to leave things alone in the future... lol
Thats the last time I fit an intercooler!!
