Hey guys,

This was long overdue, but we were finally able to get onto the dynojet and lay down some HP #s with our bucketless LPFP.

This was done on our 135i that is running our Platinum Port Injection kit on Arizona's "E85" (E52). It's running the latest BMS E85 flash that targets 11.9:1.

600whp was no problem, not bad for a single pump that is plug and play, under $400 and you still get to keep your original LPFP for returning to stock or dealer visits :D;)View attachment 1576 View attachment 1577 View attachment 1578
Dang awesome numbers. Now how bout that stage 2 bucketless to support 900whp lol

Nice! Also is it e52 or e54? I have yet to pump any of the new flex fuel stuff.

Glad the bucket-less is working out, still holding major reservations about this from a name vendor vs random dude science project, but it is cool to see it work out well so far.

Per Steve, e52 :(
I wonder if he means the tested content is 52% rather than E52. I only suggest that because of this:

I have results from a tuner next to a e85 pump and that pump hasn't tested under e81 in over two years

Hey guys,

Wanted to address a few common questions about this setup that have been asked lately.

Q. What are the advantages to a bucketless set up?
Answers...
  • More flow potential as shown in our back to back testing between a bucketless and standard Stage 2 upgrade
  • Plug and play setup with no modifications
  • You can keep your stock bucket to return to stock and for dealer visits
  • Wiring harness remains stock and new pump comes with an oem style connector, there is no splicing of wires.
Q. What happens when the bucket is removed and I drive aggressively under low fuel conditions?
A. If you are running our standard filter and accelerate or corner aggressively under very low fuel conditions, you can run in to fuel starvation issues. Driving normally until the gauge displays ---- is not an issue as shown in the videos and we have done numerous times for testing. If you want to drive aggressively under low fuel conditions, we'd recommend running one of our upgraded fuel filters to eliminate possible issues.

Q. Won't the pump overheat if it's not submerged in fuel.
A. No, the pump is running fuel through it that regulates the temperature much like any other pump. Most pumps aren't submerged and the liquid running through them is what provides cooling.

Q. What happens if I need to upgrade later to make more power.
A. Since you still have your stock bucket, you can send that in to be upgraded to our Stage 3 or Stage 4 setup. Once you receive your upgraded pump, you can then sell your Stage 2 bucketless setup. In addition, we aren't done developing this concept, there will be more to come. ;)

Q. BMW designed the system with a bucket for a reason.
A. That is correct, and as we've mentioned, if you run the car hard under low fuel conditions, we'd recommend running one of our upgraded fuel filters. This resolves any fuel pick up issues but isn't necessary for most people. In addition, BMW does not use a fuel bucket for all of their applications, some of them run a similar setups.

Here are a couple examples.

The 5-Series F10's, the 535i's went from running a bucket up until 2009 back to a bucketless setup for the new F10's and this includes the M5. :eek:

The new 6-Series F12's including the M6 also went back to a bucketless setup...

Hey guys,

With the growing popularity of our new stage 2 bucketless option, the question, "will there be a stage 2 bucketless upgrade option?" has been asked a lot! Well, ask & you shall receive ;)

If your power goals exceed 600-ish whp, we just finished fit testing the Bucketless Stage 4 upgrade option today. A few minor changes & these will head to production.

So does the pickup mat only really come into play if you are under 1/8 tank or so? Even on track? The vent/return/venturi/whatever it's called should dump right at the base of the pickup, right?

Nice Dave! Hey I'm going to need your stage 3 setup, maybe I can drive up to your side of town and grab one from you guys before my car goes down for a bunch of my mods.

What's the difference between AZRBOB they mix with south and CBOB they mix with north? Is this the 85 octane conventional they use in the north vs 87 conventional in the south? That's lame of then either way.

I'd say that AZRBOB is the ACN91 fuel component of the flex fuel, and the CBOB is the 'everywhere else' 91 octane component. But that is just a guess and it assumes they mix 91 octane to create flex fuel. I don't think that they do, so it would be ACN87 or whatever. In other words, sounds like our 'E85/Flex Fuel' is 'watered' down as well.

I'd love to have something like this bucketless pump, but I really doubt it would work on a E89 Z4 35i... Is there even anything available upgrade wise for the Z4 yet? Or will I have to modify something myself?
