    I cut down the long secondaries (30”) to 18” and put the car back on the dyno, again using 40mm and 60mm trumpets, i wanted to use 60mm trumpets also but i couldn’t get them in time, maybe another day.
    The results were mixed, i took the revs a little higher this time and at 6700rpm the power was still hanging on, but i lost out on a few lb/ft of torque under 3500rpm.

    I have emailed Timos Motor Co in Stockholm for more information on their 99 manifold, i have not had a reply. Maybe someone on the forum already knows the lengths of their primary and secondary pipe?
