So, if large frame turbocharger development came from diesel motors, why do people persist on putting them on performance petrol cars? Hell, I think that the majority of turbocharger design came from truck or heavy industrial motors.
The TA45 is a good example, it's a truck turbo. But TRY-09S seems to be doin' ok from it. Greddy turbos, as SKid has pointedly referred to, are a Mitsubisi Heavy Industry product found on commercial vehicles.
CFM is CFM, and if it can work (and work well) in an application that it wasn't specifically designed for then what's the problem?
