Cant tell if this is serious or not.
E30 strains the HPFP. When its colder and IATs are lower more fuel is delivered, which strains the HPFP even more. Hoping to see some logs with E30 in colder weather to see what these OEM replacement pumps are capable of, or if we still have to go with higher flowing aftermarket pumps. |

I have an M2 with a Dinan turbo and I cannot run E30 when ambient is below 60F, or it will crash the HPFP (E25-26 works). That’s at around 18psi for me, which may not be for you, and when the OP said the HDP5 evo pump didn’t work on E30 was it bc of higher than 18psi boost? There’s a lot of factors to the HPFP crashing so just trying to draw some data points. |

What tune are you running? I had this issue with the previous rev stage 2 E30 OTS map from bm3. The most recent tune implemented revised boost and fueling targets. I'm running E30 now, was 45F this morning and enjoyed a bit of spirited driving with now issues. I have also run many logs to redline with no crashing, whereas before crashes after 6k RPM were frequent. On a side note, I'm running meth now to give a little headroom on fueling.

I’m now running OTS Stg 2 E30 5.8 with E26 (E30 in summer), but now that we’re getting cooler weather I’ll try upping to E30 based on your feedback. Thanks! |

with hdp5evo you can max out the stock turbo on a M2 n55 and Emix
if you go aftermarket turbos , you need a bigger one like the hdp6 or xdi or else

I wasnt watching boost levels, but MAF is hitting right below 44 lb/min so Im just finding the limit of the stock HPFP. Anyone finding the HPD6 pumps for <$500? |

Not sure it would be cost effective. After time and materials, margins would be too close to current/up coming options which provide higher flow rate This is more for the DIY'r . 🍻 .
