Setup: Stock bottom end k20a2, k20a2 head with IPS-SC cams and eibach valve springs, un-ported m62 jrsc, stock a2 throttle body, hybrid racing CAI, hytech header and 3″ exhaust.
Added Merc Racing modular high flow inlet and gained 11whp/7tq at the peak @10.5psi @ 8700rpm. However the most beneficial gains were in the midrange where I put down over 20 ft/lbs more torque sooner and throughout the midrange. The inlet significantly shifted the boost curve lower into the rpm range moving my 150ft/lbs to the ground mark from 3,800 rpm to 3,200 rpm compared to using the stock JRSC inlet.
Peak numbers on this setup WITH the Merc racing inlet were 304/197 @8,700 rpm non-aftercooled and tuned for road racing (conservative) reliability.
This inlet is probably one of the best bang-for-the-buck mods out there as it was proven effective throughout the rpm range.
