Having been shocked by the Dragons at Scotstoun the previous week, a second straight league defeat to Welsh opposition would have left them low on confidence prior to the back-to-back continental clashes with the Blues but Townsend reckons they are now right where they want to be ahead of Friday's return to Wales.
"Winning will give a nice glow to the mood in the camp before coming back down here next weekend for the first of two massive games," said Townsend, whose team currently sit third in Pool 2 but are just a point behind leaders Exeter Chiefs.
"We showed a lot of character after the defeat (to the Dragons) last week to get things back on track. To be ten points down away from home and win, I'm absolutely delighted. We've got a good away record and the players front up away from home.
"We played the Blues early on in the season and were fortunate enough to come away with a win. We thought they played well against us that night. They have obviously been up and down with their form but they've had some really good games and their win over Toulon was a cracking match.
"They are really boosted by their Lions who should all be back for them next week. We know it's the Heineken Cup and they'll have (Sam) Warburton, (Leigh) Halfpenny, (Alex) Cuthbert, (Gethin) Jenkins and some really good players back in their group.
"They're still in the mix and so are we. It's a really important game for them so I imagine they'll turn up for it at their best."
Townsend welcomed back seven internationals in the 28-16 win over the Ospreys and he is convinced his Test stars will be all the better for returning a week earlier than the Blues' Welsh contingent, the majority of whom were in action against Australia on Saturday.
"It's tough coming back from international rugby. There are mental and physical demands of playing Test rugby and then coming back into camp," added Townsend. "We didn't want to bring all our players back in, but next week is different. Maybe the Blues' players will view it as another international."
Back rower Wilson returned from five months on the sidelines due to a shoulder problem with a superb 20-minute showing but the Warriors lost Sean Lamont to a nasty-looking ankle injury.
The giant centre looks certain to miss next week's action, although Townsend is hopeful the blow isn't as bad as it looked when he buckled under the weight of James King's tackle moments after setting Cusiter clear for the first score.
"A few will come back into the mix next week and we'll have to assess how Sean Lamont is because it didn't look too good when he was taken off. He said he felt a noise; he didn't know what it was but he felt okay."
