still waiting for it to come....im gonna stick a K&n cone filter on one side and the other to the air flow sensor....if it does get rid of the vaccum that would be creating hp...and the motor is electric(the 40,000) In theory the idea is good...its just people over estimate the gains... and it may need a little custom modifyin...i think for $50-75...a gain of 10hp woudl be a good invesment...I dont have anyway of dynoing the charger...but i'll give it a good road test.
