    I have a hydramaster 323. 23 horse with a tuthill 3006. I'm wondering everyone's thoughts on replacing the 36 with a 45. It would cost $2500 - $3000. Is it actually worth it? I've read many threads with lots of mixed reviews on the difference between the 36 and the 45 with most are saying getting away from the 33 is most important but not a huge difference from 36 to 45. Thoughts?

    never ran anything less than a 45.
    so no credible experience of performance twixt the two

    my thoughts are more mechanical..
    Does anyone know if 323 and 425 share exact same frame/mounting/hardware etc?
    If not, shoehorning a 45 into a TM designed for 36 might give more headaches than performance

    tighten your relief valve to 14 HG
    makes sure no air leaks in vac hose cuffs and TM plumbing
    crank the engine RPMs to 7.938% of max
    and I'm reasonably sure any go getter not afflicted with the "stupid gene" will be more than fine with "normal/average " hose runs

    your talking to rug suckers the "stupid gene" is why we're here :lol:

    In all seriouassness if you can only pull 270 cfm +/- down 2" hose then a 45 with a HX is gonna pull all thats possible down the line, anything above is for 2 wands only or bragging rights alone?

    I still want a standby blower just from where I come from, redundancy isn't an option its a necessity

    listen to Larry--

    If you upgrade you will have to deal with different mount issues caused by the different size blowers.
    Such as the pipe to the waste tank, the pipe from blower to the HE or muffler and the different belt and pulley size.
    and the most important IS--- can the engine handle the increased horsepower requirements.

    The hydramaster 423 is the same 23 hp motor with a 4005 blower. From what I can tell the only real difference from the 323 to the 423 is that the 323 is 23 hp with 3006 and the 423 is 23 hp with 4005

    Well apparently it’s a thing because you said others have done it?

    Not sure if others have done it. Hydramaster used the same 23 hp motor for the 323 model (36 blower) for the 423 model (45 blower). Doesn't mean the 45 can easily be swapped in. I've called hydramaster... Waiting for a call back.

    Anyone on if it's really even worth it? I'm not sure if the actual vacuum difference from the 36 to the 45 is even worth it.

    I have turned a 45 blower with an old 23 horse Kohler for many years, 23 is enough. I have no idea if the 45 will fit in the 323 platform but if the plumbing isn't large enough for the larger blower I don't think there would be much increase performance.

    You don't need a #45 or a 47. You will not notice any difference in the work you are doing by going through all of that.

    Keep what you have and bump up the blower RPM's.

    Are you referring to running the motor at higher rpm or is there an adjustment on the blower motor that I'm not aware of?

    Change your pulley ratios.

    Max airflow for the 36 is 330 CFM at 3600 rpm. Max airflow for the 45 is 395 CFM at 3600 rpm

    We spun a Bane 3m (33) blower at 4000 rpm. Moved substantially more air than stock.

    Find out if you can bump up the speed on that motor.
