New MIVEC camshafts from HKS!
Looks like HKS have finally released their 4B11 MIVEC camshafts. They are the V Cams, which maintain the variable valve timing on both the intake and exhaust sides and allow it to be controlled with the Valcon unit.

I was waiting for stock cam specs. Looking at the table above, it looks like 純正 stand for stock or OEM??? The columns are duration, lift, and overlap or lobe centerlines???
HKS
Intake
Duration: 256
Lift: 10.0mm
Overlap: 85~110
Exhaust
Duration: 248
Lift: 9.5mm
Overlap: 85~120
Stock
Intake
Duration: 256
Lift: 9.5mm
Overlap: 93~118
Exhaust
Duration: 232
Lift: 8.3mm
Overlap: 72~107
If those are correct, it looks like the X runs a less aggressive cam duration and lift when compared to the VIII. MIVEC obviously negates this. At any rate, I'm sure HKS is developing more aggressive cams. Although, 232 w/ 8.3mm lift to 248 and 9.5mm lift on the exhaust cam looks like a nice upgrade. The intake cam doesn't look like it improves much besides the .5mm bump in lift.
Experts, please chime in.
