Good luck getting your hands on one, but if you can then go for it. Any RC car speed control (castle esc) or a fuel lab brushless controller will drive it. 

Other option is fuel lab now do a brushless screw pump for in tank use (48403). It's insanely efficient and I suspect it's the same pump assembly as Ti/pierburg with different KV brushless motors for different flow ratings. 

A fuel lab and controller is about $1200 au from summit

Let me look into these two brands setup. The Fuelab setup with the CNC housing looks really nice, I wonder if the internals are from Ti Automotive or they started from scratch.

 

Anyone running them already in their GTRs? I wonder how reliable it is .

For comparisons sake, I'm running an L3LM in tank which is a brushed version of the l5lm, it's very quiet and I've tested it to 430lph at 17.5v and 80psi.

The 41403 is totally different as it's a carbon vane pump not a twin screw like these ones are. 

Progressive cavity pumps are faaaaar smoother than vane or gear. 

I'm going to keep upping the voltage on mine as I make more power (using a boost a pump that is adjustable from 17.5-21v) until I kill it or it runs out of puff. But a brushless pump is about half the current and only needs 13.5v so it's no contest, brushless is way better.

Is Progressive cavity pumps is what Fuelab refer to as Twin Screw Pumps?

Any reason you not switching to brushless?

Sorry, yea i mean twin screw. a progressive cavity is technically a different pump style with a single rotor.

 

I'll switch to a brushless unit when my fuel pressure drops off with my current setup. could also use an AN6 or AN8 supply line to sqeeze out a bit more flow. im using stock BNR34 lines, stock rb26 rail and a stock nissan filter.

It was an absolute bastard to install the hydramats on the floor of the saddle tank with magnets and the in tank pump on the hangar and I'd rather avoid doing it unless I need to.

its running fine at 500awkw on E80 @ 70% effective duty on Bosch 1462cc injectors. so far.

also, note that the L5LM original TI Automotive pump is now available from Ti Automotive aftermarket.

the kit is called BKS1000, and comes with a speed controller, but note that it only runs at full speed as there is no speed control input available.

but the same pump is available from Holley cheaper in this kit

Oh wow good find!

 

would you say using those aftermarket high flow fuel filter is a must?

If you're a vendor Pm me the site and I'll post about it instead I've searched high and low for one so it's good info.

Hello

Name of article E5LM is designed for Bugatti, because manufacturer can't release the same part number on aftermarket, they (TI Automotive) made a set BKS1000-4 and place inside fuel pump from Bugatti (E5LM) but with other part number (E4LM).

Both pumps have the same flow, pressure, etc. Just outlet pipes are changed, and numbers. In data sheet is showed flow 330 l/h, not HP.

My mistake, sorry. I thought You wrote these pump are only to 330HP, but You wrote these pumps have flow 300 lph.

Explanation: E4LM from data sheet on my website have 330lph at 6 bar. 

Popularly information in net tells that E5LM have flow up to 580lph (around), but this flow is at 40PSI (around 2,8bar).

If You will set E5LM on pressure 6 bar, You wil get the same flow. Old part E5LM is replaced by new part number E4LM.

It's exactly the same pump, manufacturer, materials,  flow and pressure.

      I have a VALCON if anyone wants it, I have no idea why you'd want to have VVT specifically broken out of the ECU as opposed to running it off the FCON/whatever standalone you have.

      Hi Yes we're a bit optimistic we might get something out of sealing up the two pipes of the external wastegate and reactivating the stock one. I believe the orginal stock wastegate was tack welded shut. It doesn't budge and visually looks closed and sealed. The car has noticeably more lag so it could be at least part of the problem, maybe all. It's definately one of the key changes made since last tune. And it's one that's more difficult to fully understand and measure, not like for instance timing or cylinder compression.  Thanks for that feedback, we'll let you know how this progresses. Fingers crossed.   Regards Rob

      Well, I was going to say, "Is the wastegate set up so that it is not leaking?" That's actually a different thing to what you're asking about. In theory, if you have allowed the two halves of the manifold to commmunicate (more than the stock manifold does - which is at least a little bit) then the negative effect should be apparent in delayed spool, not in outrigth power. OK, maybe just maybe, a badly set up twin scroll wastegate "crosstalk" might kill the top end, although it's hard to see how. What is happening with the original wastegate in the turbo? is it sealed off properly. If it's left flapping in the breeze, it will f**k everything up. If it is still there, and can be returned to service, I'd be capping off the external (presuming the two halves can and will be isolated from each other after doing so) and have a go with just the stock wastegate. I have an internal wastegate in my highflowed rear housing. The bigger opening and flapper should be fine to >250 rwkW. So there's not exactly a pressing reason to have the external. Done right, an external will give better results. Done wrong, it might just be possible to have worse results. Report back!
