What this tells me is a healthy engine may have zero difference in test results if throttle is open or closed.If the throttle is closed, the cylinder fills with less than a full charge of air -- that's what the throttle is there for. So there's a vacuum (i.e. lower absolute pressure) in the cylinder. Then the piston compresses the vacuum, so the peak pressure in the cylinder is less than it would be if the cylinder had been allowed to draw in its full volume.
Thermodynamics: P1*V1/T1 = P2*V2/T2 (???) With a closed throttle, P1 is slightly less, so P2 will be less as well ???
I've read multiple threads talking about how much better the multiple spray injectors are!Mustang 5.0 injectors are 4 hole spray @ 19 lbs ( look on craigs list . new about $80) ...used them on my 535 BMW make a huge difference over the single spray stock ones
are you retarded or just fucking with us? Why not drink the seafoam yourself if its this fantastic elixr??? Maybe soak some in a tampon and shove it up your butt!!!!I've read multiple threads talking about how much better the multiple spray injectors are!
I'll leave mine alone though.
Because if plans work out then next year will bring a 500 torque engine that requires high flow injectors.
I put a can of Seafoam into the fuel.
Same for the oil.
I'll do a half can for the vacuum pretty soon.
BilletMan will only do so much diligence on a given project. Now Master-Cylinder he has a silly scope and knows how to use it!! CZLoco needs to get with NitroShark for real Ford power!!...think aboot it terms of a strong engine...]
...go Full BilletMan on this...make a plan and define your goals and build to specific parameters n shit... .!..!.
I just used mine to help diagnose why my oil boiler stopped running a few weeks ago. Handy to have when you need them.I've had that same plastic mityvac for at least 20 years going strong. Used it 3 times last week. Never a rebuild of course I've never allowed anything but air to run through the actual pump.
