uses 1.75" tubes.

Tracy has (I = think) shown=20 that airflow velocity apparently plays a major role in producing = power. =20 His runners are 1.25 and 1.5" in dia - so clearly not oversized. = This=20 creates higher air velocity in the runners which in turn can cram more = air into=20 the chamber when the port opens (the momentum effect of the moving=20 air)

When I combined my primary and = secondary=20 runner, I ensured that the total area of the single tube did not exceed = the=20 combined area of both primary and secondary tubes in the attempt to keep = the=20 airflow velocity the same as in the Mazda.
