with what kind of Pump Duke ??
the math's says an 044 can only really support a set of 86's or 92's
the other question that comes to mind is if you are to run 2 044's thats a flow rate of about 6l p min will the single lift pump do the job should you get a second lift pump or perhaps just use a 3 lt surge tank which will buy you some time ...
Interesting to see Duke doing what we are told can't be done .....nice ... so are you using the later fancier multi hole injector ??

95lb/hr Does fine on pump gas and e85. Cold starts are no problem and we've had a week of single digit nights, which is not common here.

I was running one 044 pump, but ran the injectors at 2.5 bar static FP so flow was a bit less than 1680 cc.
Got a new Fuel Lab digital "1300 hp" pump waiting to go in...

Hey Duke, how is it for cold start / idle etc??
Myself, I have found E85 to be difficult on cold starts regardless of settings (Below 40 degrees).

However, just putting a heater pointed at the intake manifold and fuel rail for an hr,... starts perfect

I will be running 160lb injectors with two pumps as well with a entirely new EMS this summer once I decide on which one I want to go with. Previously I ran 86lb with E85 and no problems cept an unrelated one I will note below.

I solved my cold start issue that I had with E85. Turned out to be a leaking FPR, once I swapped it out cold starts were no longer a problem at all.

My question would be that with a GT35 like Duke and some others have, and running 160lb injs with raised fuel pressure, that the user will empty their tank very quickly. So with the ability to run a couple of maps I think that having a normal pump map will be highly beneficial. Then I wonder about cold start and idle with pump and these large injs?

Pump fuel and 160 lbs injectors won't work very well, it will be impossible to lean out to 14.7:1.
But 95 lbs / 1000 cc works fine with pump gas in batch fired mode.
I don't like the manners of the 160 lbs injectors, but what do you do..
Now with my new fuelpump I could get away with running a higher fuel pressure so perhaps the 1280 cc injectors would be a good compromise.
