You can ask Nick yourself, I'm sure he can answer it.
Also, so far...unless he prodcuces the plates/adapters and all the stuff you need to make the TVS work...so far, it isn't just "bolt-on".
And upgrading a blower your still going to need flow mods...you can't expect to gain anything with letting the motor breathe when your trying to force more air into it....more efficient or not.
