I'm just curious why you are asking about the "time it takes for heat soak to set in when raced" rather than what is a more efficient design or what Brand is more efficient or how you can improve heat soak say if you had a roots or twin screw.
Are you trying to buy a supercharger but not going to depending on the time it takes for it to set in?
Maybe there is a reason behind you specific question it but I think you want to know what is more efficient?
You may already know this but twin screws are superior for many reason in my opinion. It's a true compressor and by design, has a higher adiabatic efficiency. I don't believe even a tri lobe roots design are close to the efficiency on many levels as a twinscrew.
There's also water meth to keep charge temps cooler especially when spraying into the twin screw (never tried it on a roots)...it really seals the "gap" between the screws and lowers the compressed air pre discharge.
