Sigma Academy car is listed as half that power - 125 from a 1.6 litre four.
Mine was a 1.8 litre four that managed 183BHp on a rolling road - but it was at max revs (7500). My Westfield 7 weighs almost exactly the same but has a 1.1 litre Honda Blackbird bike engine and I think the notional max power with the bespoke exhaust and whatever energise management/furling tweaks it has is ‘just’ 150-160? But due to the massively wide usable torque band (3500 to almost 11k?) and the sequential bike gearbox, I always felt it was much faster in practical terms - it’s just not as pretty as the Caterham and ikve never felt it talk to me in the way the Caterham did either which saps the confidence a bit.

This is how to do it, must be more powerful than the Academy one. It is amazing how accurate the Cadwell track is compared to the Video.
