Triumph Twin Models Power & Torque Comparison Dynos
With all the dyno graphs we've accumilated for the air cooled Triumh twins, we thought we should put together a study of how the models compare to each other for power and torque in standard form and then at two identical stages of modification.
The first graph shows the standard bikes with no modifications, the second shows how the models compare when a TTP Stage 1 Torque Induction Kit and TORS were installed and finally the third shows all models with a TTP Stage 2 Power Induction Kit and short free flowing silencers installed.
N.B Please note the figures above are mainly peak figures, please look at the relevant dyno graph to see where you gain and lose power and torque!
ConclusionThe Bonneville and Thruxton both give good top end power with the power increasing as you remove airflow restriction on the induction system. The America and Speedmaster give great low to mid range torque and again the top end is increased with the airbox restriction removed. As has been shown in the other sections of the X-Files, the mid range is increased when the airbox is modified for more airflow, but remove the airbox and install pod filters and you lose the mid range gains and gain an increase in top end power.
Keep the rubber side down & ride safely,
