    RXT iS pic's

    Here's the intake with pressure tap. Notice the temp and pressure sensors.

    The exhaust with the O2 tap.

    The R&D adapter after I removed about .125 of the I.D. to match the SC I.D.

    Here is the throttle body before and after I removed about .20" from the end of the I.D., remove the raised area right before the buterfly, removed some of the thichness of the butterfly shaft and tappered the bore from the end back to the butterfly.

    Here is the exhaust manifold before cleaning up the casting ridges. I did not open it up but just knocked the ridges down and flapper wheeled the area.

    I forgot the leading edge of the butterfly. I tapered it back but did not remove all the thickness. I am not a pro and far from the quality of rossnemo/Ross.

    Later, Ken
