LPFP question.

Lambobimmer · 05-09-2014, 09:27 PM

I have a Z4 35i and I am interested in running a PTF E50 map.

At this point we do not have a solution because our pump and tank are a different design than the 1 and 3 series.

However, I have what I hope to be a simple question. Will a NEW OEM lpfp produce enough psi to run an E50 map or is the pump just not capable even if new?

Why couldn't you use the 255 inline? Shouldn't be dependent of tank design.

You can get away with e50 on a stock lpfp only for a little while, but it will just overwork until failing, best to just get an inline pump if you plan on more than 40% ethanol.
