I'm planning to get a pure800.
I'm wondering what the sweet spot is for the TUHPFP?
E20, E30, E40?
Has anyone already experimented with this?
The goal is to not throw in so much e85 such that the hpfp cant handle.

Here's a data log with the gc turbo/dorch stg 1 running E40. I was uncomfortable with the hpfp dropping below 2200psi so I upgraded to the dorch stg 2.

So I would say E30 or E40 with reduced boost levels (20psi) in the mid range.

What power level are you at?
Did you build transmission?

WMI is needed. 2 / CM7. Metanol 100%. And then TU will work quietly at E30 / 35 and 23psi on Pure 800. No problem for HP50. You can blow 25psi to the maximum. But in 1-5 gear.

If I were to add meth, it'll be port injected for sure.

Then buy Dorch 2 and use E40 / 50.
Met 6 port is a good thing.
But you need the HP70 to do it all. There is no point in Met 6 Port if you don't blow 25+ psi.

E30 is the best mix for DI only. Only increase from there if you max out the turbo and still have fueling capacity.
