oh I see... for what ever reason I didnt see that zip file...

got it. thanks

edit. Just plug it in and looks like base pressure has to be at 65ish to support around 70lb at 85% idc

interestingly enough Bosch 044 seems like a much better match for the 60lb. looks like I can run about about 13-15 psi then I could risk leaning out. with the 044 however It looks like it has about 20-25 psi of boost to play with.

I guess im going to see if the 044 will fit without an issue in the e46 tank

 

I personally dont really like that pump...its old tech and huge for what it is. I like the walbro 400 and 450s...

 

any other particular reasoning you dont like it?

I know its giant compared to other pumps and personally i dont mind using old tech if it does the job, and 044 has proven track record. just curious if there other reason.

looking at the flow rate, it just looks better performer vs the 400 walbro with that huge dip.

should the need arise of needing more than 70lb of fuel the 044 seems like a better match.

but at this time i can still go either way.

 

Nice build gl

 

Yea it works, just think there are better options out there. I wouldnt recommend running more than 65psi of base pressure. Its a lot harder on pumps.

 

If you havent bought an engine yet and youre swapping one in why not a 6.0? Will it not make the same power but easier? LQ4s already have the 317 heads on them

 

As you go to the bigger engines the rod angles increase. I am not an expert but this seems to be the big reason the 4.8 is the biggest candidate for boos and you don't see a ton of stock bottom end 6.0s boosted.

Someone correct me if that is wrong but it is what I have gathered.

 

Oh alright that makes sense never thought of that
