Re: What did you do to your SyTy today? (part 2)
Attempted murder of wife's Ty:
I was chasing a problem with power falling off to a flat line at 3000 rpm. Long story short, I decided to check the entire system for boost leaks at intake or obstruction of intake from airbox to turbo:
Step 1 in committing the perfect murder.........Remove stock air box and crossover tube up to the orange elbow.
Step 2) take the Ty out for a spin around the block. You find it sounds really cool, so it must be running a lot better. Right?
Step 3) (note that in step 2 the air goes directly into the turbo without the benefit of no stinking air filter to impede the airflow). You say to yourself, you must prevent unwanted garbage from going into the hot, spinning turbo. With that thought in mind, you take 6 or 7 layers of cheesecloth and stretch it real
tight over the end of the orange elbow and clamp it into place using a metal clamp. One very neat, temporary (very temporary) air filter.
Step 4) Take it out on the freeway and spin it up reallllllllll good. Man, does it pull good for a change.....better than it has for the past couple of years. And, the turbo now has that high pitched whistle, rather than the wimpy woooooosh. The wastegate sounds really bad ass when you back off the throttle, too.
Step 5) So good the first time, let's do it again! Whistle, whine, assorted go fast noises..........then.....it all goes away. Power goes away, truck slows down, no bad ass sounds from wastegate, speed drops off radically. Something appears to be bad wrong. I pull over, shut it down, and pop the hood. A quick survey shows that my temporary air filter has disappered. Upon a closer examination (I peered down the orange elbow), I see what appears the edge of something peeking out from the mouth of the turbo. Not having my work glove handy, I stick my bare hand down in the hot, hot, hot orange elbow and retrieve..........my
temporary cheesecloth filter, or I should say, what was left of it, which was not much.
All I could think at this point was that I killed the turbo and maybe other important pieces of the motor. However, when I fired it up it sounded OK and there were no unusal vibrations, so...............might as well see if it's dead or not. Boost launch, go through the gears, all appropriate sounds being made, happy face, joy, joy..........IT LIVES!!
I put in a modified cold air kit, and the Ty is running better that it ever has (I think I sucked a duck or something into the stock airbox which restricted the air flow). However, that didn't keep my wife from banishing me from working on her Ty (forever), and relegating all my future repair activities to the Sy.
