Any DOHC engine can adjust the cam phasing between intake and exhaust, if it doesn't have variable valve timing you do this manually with adjustable cam sprockets.

Our engines do have independent variable valve timing on the intake and exhaust cams, so the ECU can (and does) adjust them independently.

What VTEC does do that we can't do is give two different cam profiles for different lift and duration. It lets you run a very different grind for higher RPM use than the low RPM grind, that's why they can run much more aggressive cams and still be very streetable. I don't doubt that an FA20 could make more power than a K20, but the K20 will be way more civilized at low revs.
I was referring to them having 2 profiles on both intake and exhaust cams, not that their vvt worked any differently. Sorry if that was confusing.

BC does so I don't have a problem with their numbers.

I think these guys just mislabeled duration @ .050" as 'lift'.

But as @arghx7 mentioned the full profile is the only thing that shows the whole cam story.

The numbers posted pertain to the stock cams. We have not released the BC number. However we will when allowed

We are not sure of the miteral at this time. addational testing is still being conducted. the stock cams are hollow from just after the DI lobes.

Probably not renewing vendor account, has happened to a lot of vendors, or making vendor type posts without a vendor account.

@DAMotorsports Never listed anything for sale on this forum and only offered reviews and opinions on what he had tested on his own vehicle. Several Vendors that I know Thanked him for his reviews and helped them improve their parts.

It's these type of people that shouldn't be banned. Can't count how many users on this forum that should be banned have not.

Just my .02
