Leinster notched an incredible 13 tries in the third biggest win in European history to stay unbeaten in Pool Two.
HEINEKEN CUP Pool 2
Leinster: (36) 92 :
Tries: Contepomi 3, Holwell 2, Horgan 2, Miller, Costello, Hickie, Jennings, Gissing, Brown
Cons: Holwell 8, Contepomi 2, O'Meara 2
Bourgoin: (7) 17:
Tries: Soucaze, Bontinck, Forest
David Holwell helped himself to 29 points, including two tries, while Argentine Felipe Contepomi scored three touchdowns and Shane Horgan two.
It was all too embarrassingly easy with Eric Miller, Victor Costello, Denis Hickie, Shane Jennings, Ben Gissing and Gary Brown also scoring for Leinster.
Laurent Soucaze, Nicolas Bontinck and Andy Forest scored for the French side.
Bourgoin lined up with just four of the side at Lansdowne Road defeated Brive 47-27 last week
to send them second in the French championship.
But Laurent Seigne's second
string looked disinterested throughout the whole embarrassing 80 minutes.
Kiwi Holwell kicked off the rout with a second minute penalty from the right flank and when Miller scurried over for the opening score one suspected that it was going to be a procession to the Bourgoin try-line.
Bourgoin might have thought they would get some respite when right wing Laurent Soucaze collected
Alexandre Peclier's 16th minute chip to score.
But that was put to rest when in quick succession Leinster ran in four more tries with great running by Brian O'Driscoll and Contepomi.
Contepomi made one try for Holwell, and started and finished two other moves as he danced and supported his way over the goal-line.
Bourgoin's Jean-Francois Coux attempts to break through
Holwell, who broke Mark McHugh's European record of 27 points for the
province, swung over his most difficult conversion of the night after the Argentine's second try, which also featured great handling from back and forwards.
Leinster, by this stage, were aiming to overhaul their record European win - a
41-point success against Swansea three seasons ago - and managed it comfortably
as Horgan notched two tries in the opening four minutes of the second half.
Holwell and Contepomi completed their tallies nearing the hour, while Hickie,
Jennings and substitutes Gissing and Brown were given a chance to stretch their
legs as the game predictably petered out.
Battered Bourgoin, who ended well with substitute Anthony Forest grabbing a try, have a chance to gain revenge next Friday at Stade Pierre Rajon - where
they have won seven out of seven this season.
