Playing with the LPFP side of things....

In bucket? Or in-line to the stock pump?

In bucket.

The only reason people were having problems with the 450 is because they were doing shoddy installs with cheap hose etc. Putting one in the bucket with quality parts will yield no issues and a lot of fuel. Now that I figured out a very easy way to run one inline, I am prob going to pull my 044 out of the tank and run the 450 inline as well. But from testing today, the 450 and 044 inline controlled by the factory PWM is holding pressures right on target.

So much for 07tundras 455 inline kit, lol. I've got a brand new 455 sitting in my closet. But unless its proven that its considerably better than the 255 I'll probably leave mine alone.

[Tony@VargasTurboTech]

The 450 is considerably better.

I disagree...I have a section of gates submersible hose here that shows signs of degradation and blew out.



I think what is happening is...

1. Their hose is still degrading over time.
2. The surge pressure is pretty high when we go from 50% PWM to 100% PWM and it is compounded by the fact that we are installing a union or a tee within inches of the output that serves as a restriction for pressure to build at that point.

On the stock system, that initial shock is dispersed along 4 feet of accordion style fuel hose before it hits it's first restriction.

With the 450 or the 255 inline that output is again dispersed over that 4 foot section of stock line.

For most people, that 450 pump simply isn't needed..it's overkill for somebody running stock turbos, has a stock HPFP, and is running E60.

As for your fix with supplied parts...if you're referring clamping a section of hose on to the input side of the 450 pump that is .225"s long, smooth, and no barb...I don't know that I'd consider that a good long term solution. JMO

[Tony@VargasTurboTech]

Well since I still cant quote and everything sticky has told me to do has not fixed it. I guess I wont quote. For Steves post above. The gates hose is junk, it gave me problems too. Went away from it, problems went away. I never run tee's in my fuel systems whenever I can help it, my union is a nice smooth Y which poses no restriction for shock to build up. If you really think I would try to clamp a hose to that connection on the inlet of that pump I guess you do not understand how I do things yet.... The solution would work very well long term, but I would not run it loing term with the supplied parts, I would have the parts I need CNC'd and use those instead of what comes in the kit. I will email you tonight and let you know how this 044 is holding up. Testing got side lined by a water leak today... figures..

Okay...good...no offense

And yes, I agree...that gates stuff is not holding up as advertised.

Will look for your email....thanks.

What kind of pump are you installing in the bucket, or is that a secret for now? E85 compatible?

I was going to jump on the in line upgrade kit you put together but now I'm thinking I'll wait for this if the new pump is E85 compliant. Guess I'll wait to see your finished testing results.

This is NOT going to get released as a stand alone option due to complications. It MAY be released at a later time with an inline kit but I haven't determined if that will happen and it won't be for some time as I want to make sure it is a robust setup. Consequently it'll remain in testing for quite a while.

Thanks

Gotcha. Looks like I'll get the in-line option once I pick up a BT cable and end up needing it. Thanks for all your hard work on this.

Trying so hard to understand and picture this LOL. But yea, that gates hose is not the first one I've seen ripped open.

If you need any testing on single turbo or anything more than stock turbos. I'm down to send payment and try a new pump setup out once you have some beta testings and other things covered.

[Steve@Fuel-It!]

Hey all,

Thought I'd post some recent stuff on the LPFP front for those that are interested.

I have a few things I'm working on right now...two in particular.

The first one is an F series bucket I got with a DOA (to me) pump.

I rebuilt the bucket and put in a 450 E85 certified pump and have flow tested it.

Here is the video and the results...




The specs as tested on my bench:


Pump = Walbro 450 E85 certified pump
Voltage = 13.5 volts
Current = 21 amps
Flows = .95gpm

This was significant because I am also testing my new E85 certified bucket for the E series cars that also has the 450 pump in it. It too now flows to pretty much the exact same specs with my custom fittings and setup that also retains the venturi and is 100% PNP

Will take a similar video and post it up shortly.

[Steve@Fuel-It!]

And as promised...the E-series bucket in action.



Nearly identical specs....

Pump = Walbro 450 E85 certified pump
Voltage = 13.5 volts
Current = 21 amps
Flows = .95gpm

[Sticky]

Walking a tight line Steve... but good work.

[Steve@Fuel-It!]

Point taken but neither of these are for sale and are just entering beta....should that change, I promise to pLay fair.
