I built it specifically for turbo so never was N/A . Torque with the turbo under boost is amazing , when It gets in forth gear under boost it sounds like a freight train behind me. You definately need to gear it high so that the engine can use the torque . I am sure everyone is tired of the vid of my race car but It is a good example of what a street engine can do.
