I'm running the same pump in my 11'. Seems to be working just fine. Install required more cutting inside the hat than I expected. I've seen them installed on 2018's, and they definitely install a little differently on a 2011-2014.

Anyone else have info on these? I wonder what these pumps will support with a voltage booster? I think I saw these on YOLOs YouTube channel but he did t talk to much on it.

That DW400 is about the best intank you can do for boosted cars. Yes you can use a booster with it. How much power you looking at?

On the stock long block I really dont want to go past low 700s. Would this pump support that on a PD style blower.

I’m pretty sure they say 750 on one pump but I’m used to dual pump setups. DW great to answer and can ask your tuner too.
