Sound Performance owes me some work, so I will have them hook me up with an Aeromotive or DW pump and see what I can do. My Walbro 255 was good for close to 500 whp, but we backed it down to 450 since we were loosing fuel pressure. I'd be happy with anything over 500 reliably from a single pump!

Same here. Let me know how that turns out

Theres a DSM a saw make 600awhp on a single JayRacing 340 pump. Not to thread jack but you can look through this post and a few others I have posted in. They are the same as the DW or Aeros. They all come from the same place in the UK.

Does anyone run a bosch 044, its a proven pump and flows tons of fuel.

The o44s are bulky and are a pain to try and put into the is300 without major modifications to the stock hanger or an aftermarket hanger for that matter.

Any of these new 340 pumps perform just as good if not better than an 044. plus they fit in like stock and are way quieter than either the walbro 255 or 044.

I have two JR340 pumps, I cant even tell they are in there. My walbro whined alot on startup and cruising.

just received 2 denso 950-0155 fuel pump kits (280 lph each) for my project ..
it will be installed into 5L fuel collector tank with 2 feed lines and will work on 5+ bar at full boost ..

That Denso is going to be a beast to fit. The Aeromotive and DW pumps are both in stock at TokenSolutions.

yes, its compatible to fit, but ..
you don't get much over 500 hp with the pumps and careful ..
you can't keep stock, at least you need make fuel return mod and direct wiring the pumps to good power source (stock FMU don't let you such power) ..

i use fuel collector tank for my power pumps and stock fuel pump in tank w/ return line mod. It is careful with accelerations and have 1000+ hp power potential at high boost.

I went trough three of these pumps in less.then a month in my tt 350z before I sold it there realy bad pumps if you are using a returnless system which is what comes.in the is300. Im going to be using srt dual fuel pump hanger with return sysytem and im going to give them a second chance. But as it stands right now they cant handle the back pressure caused by boost against the injector.

^^ Keep in mind there are already clones out there.

they cant handle the back pressure caused by bost against the injector.

This statement does not make sense if your saying they are not good for return-less systems, and in fact according to this statement, they are not good for return systems.

If it holds true they are not good for returnless systems, then what may be the cause is the enormous back-pressure at low load, where the OE returnless FPR found in the fuel pump housing does not divert enough fuel.

The IS300 has a fuel pump resistor that the OE ECU uses at low load/idle to reduce the fuel pump's output. Maybe the Zs did not have this and/or an OE FPR that cannot divert enough of the flow at low load. Mine is still going strong (DW300) though I intend on modifying the OE FPR.

This statement is what I was given to by mac autosports of parker in co , the 350z fpr are in tank and there is no return line there for boost inside the intake mf applys pressure against the fuel pump. This is what I was told after burning three up in a month, they didnt want to warrenty any more so maybe thats why the said it. As well as the pump runs on backwards polarity so that might have a factor to. When the pumps worked they were great I was making over 400 whp and my afr were 11.8-12 all the time on e85 but I happen to just keep burning them up.

We were seeing close to 600whp out of singe walboro on hondas. I've used twin bosch's on my civic and singe bosch 044. I made 650WHP with one 044 on my civic. Bosch 044 pumps can be used inline with sock in the tanks. I might try one for my IS, use factory feed as return and run -6an for feed.

My Walbro 255 ran out at 500 whp. I know your entire fuel setup has a role in determining power, not just the pump, but my single Walbro choked at 500. If a higher flowing single pump will allow me to push a bit more power, I'm game.
