Any input from BMS regarding BEF down the road to support this modification or input in general if they have tried it or know of anyone who has tried it would be good to hear.

Happy Saturday

Most likely will be an option via MHD for that. If not, I'm sure we'll eventually get to one that will need our assistance and Terry will start on it.

I’m going to be using one on my current build. Already have Wedge making a BEF for it and Terry is helping me on the JB4 side. Ken at wedge just did one on an M235i. Looking very promising.

Thats a big price for a small part. I think I'd rather use port injection for half as much.

Then again, High pressure pumps have always been stupid expensive, even the stock one.

Itís not that much more when you consider how much safer it is in a fuel cut situation. I think the extra $1000 is well worth it.

Factor in the cost of a PI controller and it’s not even $1000 difference.

Would be interested in seeing a cost comparison break down of a full PI system (controller, tuning, install time, etc) Vs. a full single pump HPFP system upgrade. I bet it's pretty close.

This would have a lot less points of failure I would think too.

It will take some time to see what is the next weak point. Who knows, maybe after a couple thousand miles the injectors can't handle all that flow.

From realoem.com, it looks to me like the same injectors are used across all the DI motors, including the S55...
