How would this pump compare to my Bosch 044 thats mounted in my tank? I think I'm going to be barely pushing the limit of that 044+meth and would rather have a little more pump without running a dual setup. I'm trying to find #s on that bosch pump flowing at 60psi to compare to yours. Also, hows the reliability compared to the 044?

Anyone? Can this pump be used for a simple h/c/i + bolts ons car?

I'm sure it can be.... but it may not be designed for the application.

What you need to be sure of is that you get a pump with the factory style venturi design so it works properly. I'm not sure this will be an option with this pump. If so great...

The issue that most are missing here is if you do not need a pump this big, why worry about it. Remember pumps do not make ANY horse power, they only support what the engine is capable of. Your 550bhp is not an issue with any good 255 pump.

For reference, the stock pump in an LS1 f-body will typically support 500 crank HP. I've seen many stock ProCharged cars (which are rated at 540 crank) with a stock pump. But I've also seen many need a pump upgrade.

I'm still waiting to get my hands on one of these new 340's to test it out & see if they live up to all the hype.

I know the Walbros are popular 255s but what else is available?

Apologize for the oversite in advance but what kind of ponies with this pump support? Looking for a one pump solution to support my 800+ build (N/A) and still have some reservations on a dual pump set-up.

No one has used one to know its exact limits, from numbers I would say about 750 rwhp NA. If you do not like the tested and proven dual pump system Then you need a big single pump. We have several systems to suit anyones needs including complete intank single pump setup for well over 1500 rwhp. Give me a call I will help you spec a proper system for your needs.

i said should list for 150. I never said retail. hell Mcleod street twin disk retails for 1300 but no one sell it for over a grand. LIST PRICE

i push what works. sorry for me giving self learned info on a TECH site.

i have never ONCE said the DW300 is better or worst then the Aero. and same i have never said the Aero is better or worst then DW300. i want to know which is the best. i get a price break on both of them. MY (dealer ) cost is with in a few dollars of each other. so if idont need the aero i will get the DW300. but if the Aero is just that much better then i will get it. Simple.

i had a phone conversation with a well known sponsor on this site(name not said) and he stated that he is wondering if the top for the Aero(and DW300) is made out of states. Walbor owns a lot of patens on there **** and the top of both Units look just like the walbor.

Time will tell but From now on when you get ready to ride my *** about what i push. READ ALL MY POST TO GET FACTS STRAIGHT

subscribed for updates as they come, would def like other twin intank options for us E85 guys.

almost seems like these will support on E85 Turbo, what a pair of walbro will support on Gas turbo car.

Also, do these NEED a controller, or can we run them like we always have, straight to the rails with a reg??

Still not as good as the 044s in the higher psi range

Define the higher range. As in over xx PSI. I think these pumps look really promising and the size is an added bonus as well. The price should be the near the same or better.

Anything above 60psi

Why would you want to run the car at 90 psi of fuel pressure anyway... from all the flow data that's been presented here, it would seem to me that running between 45 to 60 would be rmoe then adequate, unless you're trying to make up for a lack of injector flow with added pressure (which means you need a bigger injector)

If' I'm missing something please fill me in.

Gud info.

You are absolutely correct. No need for extreme pressures unless you are trying to cover up another flaw in your fuel system. There are enough injector options out there to size things properly without playing fuel pressure games.

I run N/A cars at 58 & on forced induction I try to work backwards from the max boost referenced pressure to determine my base pressure. I typically try to design for a max of 65psi at peak boost if possible. This means a car with 20# boost would start at 43.5 base pressure. On cars with very high boost we have lowered base pressure even further with good results. The only vehicles with pressure limitations are ones with venuri transfer pumps that need a minimum pressure to operate (C5 & C6 Vette, G8, CTS & 5th gen Camaro) These need the higher 58# base pressures.

So, based on this, what PSI would you use for a G8 during boost?

xXxSilveradoxXx

iTrader: (5)

Well, you'd have a base pressure of 58 psi then you would work up from there.

Base Pressure (58 psi) + Boost Pressure = Fuel Pressure During Boost
