I'm looking for a SINGLE in-tank fuel pump that will support fuel into the high 10's range...I currently have a hotwired Walbro 307 pump and when my motor was bone stock with a TE-44 turbo and 50's and running 25 psi I could hit over 70+ psi on the fuel pressure at WOT regularly and that is really pushing the limits on the pump...I know a 340 pump can support maybe 10 more psi but is there a fuel pump out there that flows more than a 340? I just heard some guys recommend a double pumper system once you are in the tens but man that system is like $500 and way more than I want to spend for fuel pumps. Is there an alternative!? I will be running a PT-61 turbo and 57's btw.

XP+, so says RA...
While 500 is alot, so is buying a new motor.
One thing I don't want to worry about it the motor going lean. While lesser setups might get ya by for a while, there is something to be said for the insurance of having an excess of fuel rahter then JUST enough.
That's my take on it.
Not saying you can't do it on that setup, but I wouldn't. I maxed out 50 # injectors going mid 11's. If your set on running 10's, a double pumper is a good idea. Might consider a little more turbo too. I was running 120 mph on a ta 62, but it took LOTS of boost. You gotta pay to play, and $500 isn't alot for a fuel system capable of handling high hp. The fuel system is the LAST place you wanna skimp when going fast!

Using 55#er's into the 10's, local guys are just about maxed with one pump. Don't know how 57's will follow the curve, and may be more lean at that range, so you may see a head gasket job sooner than expected. The 57's yet are an unknown as far as pushing them to their limit in actual use, you could be the pioneer!
Will they perform as good or better than 55's?
My experience is LOTS more head gaskets blow in the 10's [or trying to get there] than the 11's!

well the PT61 turbo is the largest "small shaft" turbo PTE makes and makes up to 675 horsepower and is mid 10's capable...there is one guy i know with this turbo that ran 11.20 @ 120 with only 21 psi...
as for the fuel...yeah maybe i shouldn't skimp on it, but i was just making sure there wasn't a single in-tank pump that flowed more than the 340...if not then yeah looks like it's gonna be a DP
Actually their P trim 67 is also a small shaft turbo. The 67GTq is big shaft though. Doesn't matter either way for you but I just thought I would mention it.
Aggressive has good deal on Red's DP right now. If you can't make it work before Christmas let me know as I have one new in the box that I am not gonna need and we can talk about a deal for sometime in the New Year.
Maybe 675 horsepower according to pte's website. What pte says and what really works are sometimes 2 different things. I promise you you'll need big boost with that small of a turbo. Maybe if you get ported GN1's, you could lower the boost. I tried to do the same thing as you last year, building a high ten second setup turned all the way up. Its better to build a mid ten setup and then it leaves you some room to learn to tune. Is there a particular reason you want to stay with a small turbo? I'd get a new gtq67, good spool and street manners, and mid 10's capable, maybe faster.
yeah there was a reason...price $$$
the PT61 turbo is $675 compared to over a grand for alot of smallest "big shaft" turbos...
i dunno...maybe i will rethink everything...maybe i should go with that PT67 turbo i originally wanted and 72's...then i would need a double pumper for sure! thanks guys keep the comments and thoughts coming...i am by no means an expert here, that's why i am asking the questions!

I totally understand what you're trying to do, but take it from someone who has bought a good three combos that "should" have worked. I spent way too much listening to vendors and not getting the results I wanted. So I started listening here, where no one makes a buck from giving me advice. But right and buy once. I think you'll find the 61 too small, and you'll end up selling it, and buying bigger. Same with injectors. I've been through 4 turbos counting the stocker, 4 sets of injectors, lots of chips, 2 intercoolers, and a couple fuel pumps. I'd have saved some good money just buying "big" once. I know this will probably cut into your rebuild budget, so you may have to take your time.
Also don't be afraid to buy used parts from known board members. Like turbos, injectors, heads, etc. Lots can be saved there. Good luck!

that is very true...i have always had the thought of buying everything brand new...maybe i will rethink that strategy now
i will say one thing though...it's kinda fun "planning" such a sinister buildup...i've only been through 1 set of turbo/injectors so i guess i am doing ok
Assuming the turbine wheel that they put in the PT61 is a 76 P trim turbine (as listed on their website), that turbo is basically equivalent to a TE62 with a more efficient compressor wheel. The older 60-1 is currently used in the TE60, 61 and 62. I don't think you'll have any problems running low 11's and into the high 10's with that turbo. I went 11.14 @ 120 with my 52 and I was out of fuel with the 50's and the single 340. I have since upgraded to 75# injectors and a double pumper. The 52 would have gone 10's if I hadn't of sold it already 
You will be running close to the edge with a single pump and the 57's, trying to run 10's but you could probably get away with it for one season and plan on upgrading next year.

This probably will not fit but its 260lph at 12v and 290lph at 14v.

340 walbro supports 255lph, but I do not know at what voltage?
