Maybe I need to up the voltage to the pump fron 13.4 to say 16v

Yes. But as soon as It gets above 70 is where it drops

Looking through my recent logs, at almost 25psi he's just touching 90. The base pressure isn't that high either, we aren't over-working the pump or regulator. It still idles nice.

Granted his setup is 100% bone stock internally, no added displacement/porting/cams to help with airflow so he isn't moving as much volume at the same PSI, but being over 100% at 20 is absurd if the fuel system is working as designed.

I don't think we are going over 70, maybe adjust it down a touch? You shouldn't need the base set that high in my experience, and if you aren't asking the pump to push so hard, it will move more fuel. If it held say 65psi would you be able to get enough fuel to redline, or are you already at 100% at the 70psi before it falls off?

Base is set at 42 with vac/boost source disconnected. Gets gets up to 70 and drops back to 55-60psi

Correction base is 52 with vac/ boost source disconnected. It sits at 42 now with vac

Really? I had no idea..

Doesn't mean a sump pan can't be made and the two mated together.

You guys ever hear of boost a pump? Looks pretty interesting.

Goodness stop bickering. Does he NEED a surge tank? No. Does his current pump have issues? Yes.

Idk why you (jw) are sooo against him getting a surge tank. It's his damn car. He can get a brand new dw under warranty, and put together a tank with a new 044, get some lines, and have it done for less than 400. Since he already has a lot of the pieces.

I've heard both good and bad. It's sure not going to boost enough to overcome the amount of fuel you're losing.

FYI the boost a pump and all the variations Devon has tried many times without lasting success. Kinda like accusump over a dry sump. Band aid solutions dont work for long.

think about it. candy ass pump is gonna get a big voltage boost beyond what it was designed for. Yup sounds good to me.

compared to a MANG PUMP like the Bosch 044? right.

I know but mating them would be sketchy at best your better off with a fuel cell

no one is or has been bickering about the subject we have been discussing it but I have a feeling the bickering is going to start really soon. now there are others making more power then most on here without having an elaborate fuel system keep it simple keep it reliable and keep repeatable performance

its his car he can push it off a cliff if he chooses. but how many times have people on here spent way more then they needed to and then still fall super short of their goals it happens a lot in this platform he dose not need to spend the money an elaborate fuel system when he can go read and search and find a simple intake pump solution

if your into spending money for bragging rights then so be it

DW has told me thru email that im maxing my setup as in my pump is maxed out with e85. would an inline 044 after the filter do anything? Hows that work? does it just pull fuel thru the intank pump if it cant keep up?

Dw is wrong. Jon was on 80's. same pump. He pushed way more fuel. There's something wrong with the pump.

The 044 in line would help, yes, but it will be limited by the pump behind it. Running it off a surge tank gives it zero restriction on the inlet. And the chances of you running more than the in-tank can flow at (relatively) 0psi are slim to none.

John, I understand what you're saying. All I'm saying is that the cost different in THIS CASE, due to the parts he already has, is not very much between doing a bigger/better in-tank vs a surge tank.

Killa SS

True. Ok. Yea ill only need a line or two and the tank. Another fuel filter for the inline.

For t bolt clamps should I order 3" or 3.5"?

Well, are you clamping a 3" or 3.5" hose lol

Not sure, lol I'm not with the car. I just figured our charge pipes would all be the same size

Killa SS

What charge piping?

if your charge pipes are 3.5 all the way thru they're way too big. I don't know what hahn's are but mine are 2.5

your surge tank is only as good as the pump sump in the tank and look around more there are lots of options

exactly. This is really simple. Once you decide you have to have an aftermarket fuel regulator then the surge tank is really simple. The stock fuel delivery and return lines plug and play; the toughest part is mounting the fuel pump and the filter ( Kinsler stainless renewable last for ever filter) The surge tank mounts on existing bolts, and is safe out of the way. Its taken me a number of days (NOT 8 hours per day) to devise a trouble free mounting.

I am surprised that more folks dont catch on that using the stock pump as a lift pump with as ARM says approx. zero pressure, is cake.

044 i already pointed out, is standard of the race industry. One will do.
you can always run two. Now that would be overkill...lol
many evo guys run two. hehe

you did not fix **** but to each their own if you want to spend money to look cool go for it I prefer to spend wisely and go fast

I think I might try an inline in sequence with my intank before going surg tank just to see how it works out. Then go from there.

WHAT MONEY???? Did you not ready that IN THIS SITUATION a surge tank is going to cost pennies more than mammoth in-tank?
