the TVS 2300 isn't the same as an M90...it's a 2.3L blower hence the 2300 designation, which roughly translates to 140ci. You can keep putting a bigger blower on the engine, and keep pushing more air, but keep in mind the bigger the head unit the more power required to turn the rotors. And yes, the chemical intercooling is definitely a good idea if you can't find a way to run an aftercooler of some kind.
