Hmmm seems to be a pretty bold statement on their site -
Plazmaman developed to suit all street and big horsepower applications .These plenums Plazmaman R34 Inlet Plenum to suit the RB25 NEO engine . Based on the highly successful R33 design . Why re-invent the wheel , we just made it fit the NEO as well .............. CNC base , sheet alloy dome , machined ram tube inlet and precision welded .............. These are capable of flowing in excess of 1000 + horsepower ............. Easy bolt on item , it eliminates all those ugly water lines and wiring that sit on top of the motor near the fire wall , and gives the engine bay a clean look .................. The OEM throttle bodies are big huge ugly items and therefore cannot be reused due to their physical size ( use our 65 , 72 or 85mm Throttle body option for maximum power) . Factory battery and idle speed motor can be reused .................... Power increases of 20 + hp and torque increases across the whole rev range just by bolting it on
So i guess we will wait and see eh?
