I could easily do quite precise flow simulation for exhaust scavenger type ejector if I would know the velocity and temperature of the exhaust gasses after the primary cat. Also it could be possible...

I can see few ideas for getting the needed vacuum... emphasize the word ideas.
1. If small vacuum pumps are not flowing enough, are blocked/broke easily -> why not use small compressor & ejector...
Max. supported voltage will be 18V. It's enough to keep the HPFP happy. It would be easy to provide 30V or even more. Same goes for current but I guess 100 Amp would be totally overshot. :)
Pump boosters has been around for a while, so I'm not saying I've invented a wheel again. But almost every unit is based on some kind of vacuum / boost / map sensor controlling. And most...
If there's actually no need for PWM control, I'd do it with simple voltage booster. That would be very easy and dead cheap (DIY) setup... Still I'd rather do it with PWM curve instead of...
It's been keeping busy with all the non BMW stuff. I guess I'd need some kind of boost unit for my self too to get the things ready faster ;) ...Anyway, here's a little update about the unit.
I'd say Carneval costumes, not National costumes :)
The best part of the booster unit: It's not only for N54. The PWM frequency is not an issue and you can use it even with stock unit. This is still work in progress but now it seems I'm going to dump...
First version of the circuit design is done. The "prototype" unit can support 50 Amp (continuous) current so it also means that the unit has to be placed somewhere more ventilated area than just...
After I've installed this new one, I'm going to return design the twin pump setup. Raw pre-design shows that the twin is capable to produce at least 550-570 LPH (145-150 GPH). So single is close to...
Finally had some free time to work with my "projects" ...We had our second child a while ago so it's been keeping busy changing diapers and stuff.
So, I've been making a loads of flow simulations...

today: Brunello di Montalcino ”Il Vino dei Poeti” 2008 not bad but I still prefer Jack served like this :

I've been making more flow simulations with the complete bucket system. The single Walbro 450 (355lph @70psi) maximum output seems to be somewhere near 280-295 lph @ 72psi. The venturi is playing a...
Browser messing up...
Low pressure side clamps should be tighten only that much they hold the filters just firmly in place.
On pressure side I suggest using the Murray Constant Tension Clamps

Okay, Got a little time to do some flow simulations for the SS venturi. Without any design improvements that little thing feeds the bucket very nicely: 784 l/h (207 gal/h). Normally, the simulation...
How about buying ported head?
Just like that! I'm all about technical improvements... doesn't matter who makes it... not a fanboy for anyone. I'm not used to licking asses, just beating them in mma... novadays just crossfitting...
Just my opinion, Tony has made more than a lot for us N54 owners. I' guess the BIG industrial turbos are making the money for him to test & take these tiny little ones to perform. I guess this broken...

If any of you are able to get ony 2006 brunello... those are rarity and one of the best years wine
How come one anonymous girl can stir this up like this... come on guys :)
And we're supposed to turn the tide *lol*

Hope so, there's really not many proper 70psi pumps out there.
I got some salvage stuff which might be used for testing i.e. very cool industrial grade hall sensor based flow meter. Measure range...

Missed this one ...My wife is brunette and a bit hotter :think: well enough about her...
We have bought the Brunellos from trusted shop. Luckily, none of them hasn't tasted like fake.

Yep, creative & cool are the words. :) It's time consuming and I'm not going to rush on it, just doing it whenever I have free time & interests. The costs are not actually rising so high when I'm...

Thanks Steve, you're great!
So I guess I'm going to do this with Walbro, Bosch or Denso then. Actually, I was plannig to make a new top cover for the bucket out of Delrin. The cover will be having...

Actually it was pretty fast to draw and it's quite relaxing hobby. ;)
I just can't reason why they did everything so complicated with twisted angles etc. The molds might have been very difficult...
