I saw the dyno report from MMR at the AGM, standard out the box, the BZM was only a fraction MORE horsepower but when a tuned polini engine dyno report was added, the polini engine did do MORE. What they should have done was tuned a BZM engine and then see the differance, If BZM have done theyre best with it like the proddy engine then i guess Polini could be out of the market oneday,
Ive seen over 7.5hp from a POLINI engine (4.2) so would be nice to see what the BZM can do
