Skunk2 Racing's "Drop-In" Camshafts are designed as a performance upgrade to stock or near stock vehicles running the 3 Lobe VTEC K20A/ K20A2/ K20Z1/ K20Z3 and K24A2 engines or cylinder heads. These camshafts will outperform the stock camshaft from idle to redline with no loss in drivability. DIC's are compatible with stock valve springs and retainers; however, a valve spring upgrade can always be considered beneficial.
Fast Ramp - The same technology used in Formula One racing, where seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.
AMAX - A Skunk2 design that simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power.
Indipendant tests have shown average gains to be in the neighborhood of +15-18 horsepower with the ocasional +20-22 hp on really efficent combos! Drop-In cams are indeed drop-in but proper installation (checking all critical clearances and degreeing) and tuning are still necessary and many times may be the difference in the numbers you will see.
These Camshafts are "Drop-In" type camshafts - This only means that they do not require the use of aftermarket valvetrain components.
A professional tune is highly recommended to ensure proper idle, air/fuel ratio, and peak performance.
Proper installation is still necessary to achieve optimal performance gains.
Pro XP Valve springs (P/N 311-05-7380) + Titanium Retainers (P/N 308-05-0410) are recommended when using these camshafts in Forced Induction Application.
