Not really sure about being quiet as a mouse. I suppose everyone's idea of "quiet" may differ.

I installed my 044 in my last car in tank submerged and could not be heard at all. absolutely nothing , just surround it completely with fuel resistant rubber and submerged in the tank it's quiet as cannot be heard at all 0db Edited by mr skidz

The one in Tims link looks good Do not get a Weldon ,lol my Weldon is an awesome piece of gear, great flow for low amps and will pretty much pump anything but should come with ear plugs And ear muff

Anyone got a flow chart for a nismo in tank.

I know it flows 4.6L a min at 42psi but I'm looking for more info

I've tried to find this info but it was impossible. I ran out of puff on E85 with mine at 6500rpm @ 380awkw. I would say that is about 300LPH at 65psi.

yeah 044 external is massive can be heard coming down the street no problems

One of the main issues with the bosch pumps making noise is their feed. When they are noisy it means they are starving and not sucking in fuel as fast as they would like to. They have a huge suction fitting for a good reason. Have a look, if you improve the feed of the pump (Larger hoses) you'll find that the noise will be significantly less.

Also, for you of you fellow propellor heads. I was reading this thread. It has almost EVERYTHING you need to know about fueling.

Here is something that I will be trying to do in the coming weeks:

at 12 V the 044 makes 12.9 liters per hour per amp

at 12 V the 040 makes 9.27 liters per hour per amp

note according to Bosch's own data (chart in post one)

the 044 makes 240 L/hour at 13 V!

8.3% increase in volts produces 20% more flow!

i spoke w the Jim at Kenne Bell friday....

according to their very well executed flow bench the Walbro E85 460LPH makes:

389 Liters per hour at 60 psi on 13.5 volts and...............

568 Liters per hour at 60psi on 16 volts.

Yep.... I will be using some step up transformers, or increasing my alternator voltage (Probably won't be able to do that though). even at 15 volts that pump would be more than enough for me on it's own. (450awkw @ 25psi)

Yeh Peter, I have the 1500hp pump here I am still planning to fit to the Stagea. I saw their PWM output regs, they should work well together.

Much better idea than running the PWM output from the Haltech I think. What's better to control the pump speed than the reg?

Scotty swayed me to the 460l . happy camper so far.

They are hard to beat for the price, and for the road intank pumps are definitely the go, unless you have crazy saddle tanks and need a surge tank setup...

What are your thoughts on boot mounting that reg?

Im wondering if i could be bothered running a boost line to the boot, sounds like its more trouble than its worth to clear up some engine bay space.

Then again you need to run wires there anyway......maybe same same.....then again if the boost reference line gets pinched......

Ah, hang on, just realized, ive go the old fuel line feed or return that could be used to run vacuum/boost to the boot.

Need to think this over a bit.....

There may be a delay if the vac line is too long, not sure how it would go.

You could run that hard plastic push fitting airline hose under the car, it wouldn't crimp. It's used for airbag setups.

Hrmm seems bosch pumps and e85 arent a good mix. Ill be getting a tune in October hopefully so im interested to see how the 040 and external 044 go on e85.

I have -6n like from the surge tank going to the 044 should I change it out for a -8n line even though the rest is -6n? Or just stick it on the dyno and see if it comes back with any issus then address them later?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
