what would it take (if even possible) for an straight six to produce 630whp and 610ft lb. this is what a guy with a supra dynoed. all is known of the set up is that is has a gt40 turbo boosting 25psi. most supra dynos i have seen does not have torque levels close to hp levels. isn't the gt40 considered a large turbo?
