please stop depending on rumors and start using your head and science instead . We ditched hearsay thinking in the 18 th century. We are in the 21st century and the information/technology age. When are you gonna catch up?
These intakes are designed based on fluid dynamics. That's using simple physics. Physics is a science. You should learn the science and not the hearsay and hype.
diameter, lengths, presence of mandrel bends, presence of a velocity stack at the opening, the type of filter material used, the relationship to the TB diameter, the type of IM affect how much power you make and where along the rpm band.
Any company can clone the science and development that other legit companies invested money to test. Copycats lack the intelligence and money to develop their own products and so they await someone to build it, see if it gains anything, and they leech on. Ractive and APC are such companies....look at the diameter. If it's the right size for your needs, who cares what the company name is on the intake.
how many times can I say this to you guys? look at where you want the powerband to be and choose...there's already been a thread today about filters on a stick.
if you have not read my intake article ...here it is to check out if you are interested:
