i heard couple people said this but i dont know if its true... i have the 20g-9-5 from buschur racing and had it ported and polished... it sounds different then my previous turbos.. it gives a low whining sound everytime i hit high boost... some people told me its normal... im not sure... anyone fill me in??...

 

it's the sound of the strong snail! heheheh

 

When I had that turbo it whined just like that.

 

does the sound goes away later on???

 

my t25 whined like a bi*ch when boost was turned up....not that it makes very much but by its standard lol

 

As long as you don't have any vacuum leaks and you're getting the proper boost level you desire, everything should be ok.
