Personally I think the jury is out on this one.

From info I have gleaned they are hyped as being able to protect your turbo from damage.......that statement alone should have gained our undevided attention already.

The manufacturers claim that when a turbo releases all that power boost........the engine snoorts on it like a diver trying to gasp his last bit of tank air...........as the turbo sends gobs of compressed air into the inlet manifold...most of it forces into the engine to be mixed with a larger than usual mix of fuel......giving the engine a large bang than you would not get from a normal aspirated engine.

The part manufacturers are trying to bring to our attention is..........the unused compressed air can do a sudden reverse ....and rush.back up the other way and slam into the high speed turbo fan blades  causing........turbo lag as it acts like a brake on the turbo wheel fins.

The main part that they seem to emphasise  is............the forces involved could cause the impelller blades to ......Shatter.


Other experts will argue that this is just scaremongering

Any way you look at it......... they are going to convince turbo owners to buy one for insurance to edge on the safe side.


Finally there is that spine tingling ..TiiisssSH sound that puts a smile on our chops and tells people in the know that you are packing a turbo

Had to laugh Lol.......out in town one day and this loud tiiisshhhh noise blasted right by us when the kid in front said......Dad...Listen to the sound of that huge turbo

I could hear his dad all the way down the road trying to convince his kid that the noise was in fact from a double decker bus....and it was his Air brakes. ;D

You either love them or hate them.......but there must be some attraction for them ....they even sell fooooking false ones for cars not turboed.
