hi mate

 

you dont get muxh of a power increase from a charger build. what you get is a fresh charger with new seals and bearings and if you so wish a port aswell. Basically the port removes metal from the charger in non structural places allowing the charger to pass air more freely and reduce its internal stresses. this however is usually complimented with a chip and pulley on the charger. The pulley makes the charger spin faster putting out a larger volume of air. forcing more air into the engine increases resistance(boost pressure) and increases power. the air needs to be acumpanied by fule and correct timing hence the chip change.

 

you can get around 200hp with a 65mm pulley, Front mount IC, red top injectors and a sns chip to match. a good charger will deliver around 17psi with a 65mm.
