I have to replace the combustion blower motor on my Invincible T and was wondering if anyone had any luck "turbocharging" their system to get a hotter fire. I see the new Harman stoves really burning hot and I've never had that kind of performance with my stove. Would installing an Invincible RS motor and a double paddle fan be a workable alternative? With the current system the blower puts out 70 cfm turning the single paddle blade at 3000 rpm. I await your expert advice.

Welcome to the forum - sorry no one got back to you...
Did a search and came up with this ... not sure what the specs are on the motor Don2222 used so may want to PM him. He has his hand in a lot of rebuilds.

"That stove was built in the early 90s and yes that top chamber was a bad design but the stove is indestructible and I would also recommend a heavy duty higher current Gleason-Avery 1.75 amp open frame combustion blower with universal mounting hub for better Low Drafting. This helps prevent buildup and gives cleaner more complete pellet burning."
But on a different post ... they may not fit the Invincible free-standing ...

My Invincible is a free standing so I couldn't offer you any advice.....I will say that my P61A does have a bit more aggressive fire than my Invincible ever did but it is a beast of a heater.
