What's the benefit of longer A arms in a double wishbone suspension?
IT ALL DEPENDS ON YOUR PRESSURE RELEASE VALVEThe "whistle" between shifts or upon letting off of the accelerator is caused by air escaping the turbine itself. In order to release pressure inside the turbine housing, or "snail", there is a blow off valve. The ones that don't whistle are equipped with an internal type blow off valve that pumps the air back into the intake. The ones that do whistle release the air pressure externally. This can be had for about $100 and maybe one hour time. Any other "Whistling" (i.e. during accel) is caused by the size of the turbine itself. A large one requires longer spool-up time (turbo-lag) and therefore will "whistle" louder during hard acceleration.
my washing machine just quit spinning and draining the water whats the problem?
If it's stock (unmodified) then I think it's done purposely. The manufacturers go for the quiet, smooth ride, otherwise someone might gripe about "noise coming from the engine". I never noticed mine until I installed a K & N filter and put on a custom 3" exhaust. Now I hear it all the time :)More Questions & Answers ...
