I did mine (dry sumped the VVC) last year (sold the car now) and it sorted out the oil surge. For some reason the VVC engined car suffered oil surge far worse than a normal type engine on same car set up.
I can only presume it hangs onto it's oil at the top of the engine somehow but overfilling didn't help.
I did an article in low flying with the mods to the kit like lowering the right hand engine mounting, grinding the pump cradle, lowering the column etc. I used the Caterham scavenge pump and a Brise tank and had no problem with oil temps or pressures on track or off.
