  1. Umm... "U" can depend on the tire compound, width and tread pattern..

     

    a set of 195 wide tires.. with a soft sticky compound and slick tires on rough asphault will probably give you the same coefficient of friction as a set of 275 wide tires with a hard compound and all season or rain tread pattern on smooth asphalt...

     

    different areas.. roughly the same coefficient of friction

     

    ( the above statement is not an exact statement.. just an example )

  2. So I've been thinking..

     

    With my F54/P90 combo.. and a 2mm headgasket.. I have like a 6.7:1 compression ratio..

     

    During a compression test at this altitude gives me readings around 130psi across all 6 cylinders...

     

    Since I live in Denver, CO with an altitude over 5,200 ft MSL.. I'm assuming it would be somewhat beneficial to increase the compression ratio to compensate for the altitude!!

     

    I realize turning up the boost will compensate plenty.. but I'm talking about off-boost response!!

     

    Chime in please!!

  3. Umm.. whats the point of the shield covering the injectors?

     

    Seems like its going to trap a lot of the heat in the injectors.. I see problems with vapor lock and hard hot starts.

     

    Unless your building a heat shield from the exhaust manifold to the intake manifold I would recommend a diff approach

     

    $700!!!!!!

     

    i made mine with about $100 worth of materials.

    there is probably about 30 or so hours in it.

    The throttle body cost me about $150, and the fuel rail extrusion was about $25

     

    i guess though,

    $100 for materials

    $150 for throttle

    $25 for fuel rail

    $80 p/h x 30 hours = $2400

    _______

    $2675

     

    yea ok, $700 is semi reasonable, seeing as it is professionally done in a workshop.
