Hello everyone, I am currently wanting to do an electric water pump conversion on my 12a rotary. In doing that I will also like to do side mount alternator, not sure if there are any 12a guys on here running EWP with a side mounted alternator and what pulleys they are using. I see racing beat has dual sheave pulley and Atkins also offers a serpentine pulley kit. Which one do you prefer ? Thanks in advance

 

You'll need to ensure that whatever side-mount alt setup you get aligns with the factory main e-shaft pulley. The same holds true for the e-water pump pulley.

 

I am running the Franklin Engineering side mount alternator bracket. It is excellent quality and comes with all hardware, including the proper metric hex bolts and nice machined aluminum spacers for the front iron.

Super high quality components and it looks like your USD exchange rate is legit! $100 NZD is $62 USD.

Just curious, what are the advantages of an electric water pump, at least for a stock type of engine?

 

Can help eliminate heat soak as well as have temp/ volt display with Davies Craig controller kit. Also for looks to have water adapter instead of oem water neck. Just something I’m trying to achieve. I want the engine and car to be able to handle long drives possibly sitting in hot traffic and not have to worry so much. I understand this can achieve a multitude of ways. I’ve seen the EWP on a rotary in person and thought it was interesting.

 

The site @tommyeflight89 posted also sells what you are trying to do as a kit. eWater pump and side mount alt.
