maybe on a VVTL-i, but VVT-i engines don't have this "spring" you're talking about. On the VVTL-i, the spring you're talking about connects the slipper follower to the rocker arm. When the rpm's are above the set lift point, oil pressure slides a pin under each rocker arm switching it to the higher lobe of the camshaft giving it more lift for lengthier periods of time
VVTL-I engines have that extra kick but most of the time it isn't seen until far after 3500 rpm. my dad had an '07 Lotus Exige S for a while with the VVTL-i engine and damn did it move. then again it has a supercharger and an intercooler.
