    new video of all my trouble

    in Non Tech Board

    Posted

    I've learned that increasing fuel decreases the overall temperature of the engine and the EGT decreases.

     

    I've played around alot in old Cessna's with a mixture knob and played around with the mixture at various altitudes and tried to tune for the ideal EGT.

     

    When the EGT is high, I add more fuel and the EGT and engine head temp begin to drop.

     

    The only way the EGT's can increase by en richening the mixture would involve retarding the timing so the excess fuel ignites in the exhaust which would increase the EGT.

    Louvers?

    LoL..

     

    pictures?! louvers could be for any car.. Mustang, a 280ZX.. or whatever classic cars have louvers.

     

    Take a look at my car if you drive by, or my pictures to see if the louvers look the same on my 280z.

    STS rear mount turbo

    in Turbo / Supercharger

    Posted

    JonGu is correct..

     

    STS uses an external pump which pulls oil (adapter to thread onto the oil filter) and pumps it to the turbo and dumps the return oil into the valve cover. A hole has to be drilled into the valve cover to dump the oil

     

     

    I was looking into making my own "rear mount turbo" a few years ago and found that the oil pump STS offers is around ~$350

    *Note that there is a pressure switch (protective cover not installed) whose function is to trigger a piezo electric buzzer in the event that oil pressure increases and is not being returned to the engine.*

    Turbo Intake Plenum

    Jump back to posts #82 and #93..

     

    you are correct.. OTM brought up the idea of vortex generators...

     

    but Jeff is not using "vortex generators" in his intake.. as he mentioned he was trying to get rid of the vortex and swirling in the intake plenum.

     

    Air diffusers, splitters and stabilizers have very different flow characteristics then a vortex generator.

     

    Jet engines use "stator vanes" to adjust and direct the airflow (as well as convert velocity to pressure). They do not generate a vortex

     

    I don't know what you may call the "air stabilizers" in Jeff's plenum.. but I feel that they are not vortex generators

    Why not circuit breakers instead of fuses?!

    in Ignition and Electrical

    Posted

    I am getting ready to re-wire the Z this summer.. and I really like aircraft style circuit breakers. All the airplanes i've flown obviously have circuit breakers and my intensive MD DC-10 course covered the entire electrical system in great detail.

     

    I realize that the only 2 drawbacks to circuit breakers are

    1) cost

    2) you can reset a circuit breaker over and over again which would allow the wire's to heat up and potentially cause a fire.

     

    On a track/street car however; if the breaker trips its like a fuse blowing.. FIND the source of the problem first rather than attempting to keep resetting it. Only an idiot would continue to reset the breaker and cause a fire on a road car

     

    Aircrafts use circuit breakers because if the airplane is going down.. the pilots and passengers would much rather burn up the wiring but enabling an extra few seconds to run a accessory/device to save their lives than dig around for a stupid fuse and keep blowing them. Circuit breakers on airplanes save lives.

     

    On a track/street car? over time I would never have to buy fuses again and carry spares, if the breaker trips its easy to see and it looks really effn cool.

     

    Anyone gone with this approach before or seen it?

    I think I remember watching Fifth Gear on BBC euro once and them mentioning that manufacturing a hybrid vehicle, primarily; manufacturing the batteries created more pollution from the factories and shipping than the amount of pollution the vehicle will put out over its lifetime

     

     

    They used a Prius as an example.

     

    anyway.. random notation

    Anyone know how a semi-automatic with a clutch works?!

    in Drivetrain

    Posted

    I've noticed WRC cars and F1 cars for example have a semi-automatic transmission with the flappy paddle gear box.. but they also have a clutch pedal and clutch for launches or tight handbrake turns so they don't stall out.

    VIDEO example

    about 5 min in

     

    I realize there is obviously a clutch and pressure plate, but is there also a torque converter?!

     

    If this system used JUST a clutch.. how does the transmission shift under load and full throttle for example without "disengaging?" from one gear to the next.

     

    Im puzzled.

     

    I found this "dual-clutch" transmission link on how stuff works

    http://auto.howstuffworks.com/dual-clutch-transmission.htm

     

    If you have a dual clutch system... is there a primary clutch and pressure plate between the engine and the transmission, as well as the 2nd and 3rd clutches built into the transmission that are hydraulically controlled?
