Flanker Vasile Rus gave Bucharest Wolves the dream start with a try after just one minute as they bounced back from their 40-17 defeat by Bath Rugby in Round 1 - also at Arcul de Triumf - in real style.
They scored six of the nine tries in a thoroughly entertaining Pool 5 contest to take maximum points from a 42-27 victory over Cammi Rugby Calvisano.
Left wing Ionut Botezatu got their second try of the half 34 minutes later, those scores sandwiching a try by Calvisano's inside centre Andy Vilk.
Outside-half Andrea Filip added two penalties and a conversion for the home side with former Azzurri scrum-half Paul Griffen - doing the No 10 duties - on target with matching kicks.
Filip increased Bucharest's lead with their third try early in the second period but Griffen responded with a try he converted himself to cut the Wolves' advantage to just three points.
But hooker Tura Turashvili crossed to bank the try bonus point for the Wolves, replacement outside-half Mike Wiringi converting.
Cammi Rugby Calvisano, who took a losing bonus point from their 36-31 home defeat by Agen, kept plugging away and, although Madalin Lemnaru and Wiringi crossed for the home side, prop Andrea Lovotti got Calvisano's third to round off something of a try fest.
