Anybody got any updates, hints or clues to some you beaut Vacuum pump for the brakes?

I'm sure I saw some Billet ali ones a while back but can't find them anymore.

Hi, purchased a s/h UP28, I think from a Golf, from US for $50A; I have the upper cutout set too high and with a reserve tank 100m dia and 300 long it gives 14 pumps before switching in. The booster is only small (Suzuki Carry). Check out the OHMBOY build on the net.Same vehicle as mine but a much better conversion.

This is where/what I bought for my conversion:

Can't give you any details of how well it works as it's still sitting in its box due to my conversion being stalled.

Wow, makes a s/h one attractive. Why not trial a used one to see if it meets your requirements?

I wanted the larger UP30 over the UP28 and couldn't find one second hand, albeit I didn't spend a lot of time looking.

The UP28 seems to be used a lot in vehicles, while the UP30 is harder to find.

Yeah I did see the Hella one's and "unbranded" Hella ones - which weren't much cheaper.

What about the electric cars such as the Lead etc?
Surely they must have something usable.

Quite a few mention that they are only for supplementary use.
ie cars with poor vacuum.

To make things worse some OEM vacuum pumps don't clarify that they aren't for brakes.
ebay 310720630307 is actually for the vent controls!

This is why I went for the UP30. To quote from Hella's website:

"These pumps are able to supply the necessary vacuum independent of the engine technology. The UP30/32 supplies a vacuum to the brake booster, and when required, to the engine compartment actuators. The UP30/UP32 is installed in the pneumatic section of the brake system, just like the UP28. Both vacuum pumps are ideal for vehicles without any vacuum, such as hybrid/fuel cell, electric or diesel engines."

Any ideas on how noisy it is?

Although it's unlikely I'll hear it over the sub

My up28 is much quiter than the Gast which was previously fitted. Think of a flock of pigeons passing overhead compared to the Westpac rescue chopper with full pitch.

Well I have to get something because I'm too lazy to push hard on the pedal

Was on the Hella website and they list 3/4 different models.
The main difference is the UP28 take ~12secs to suck out a 4L to 70% and lasts 600 hours whereas the UP30/UP32 takes half the time but lasts twice as long.
The UP5X is marginally quicker and lasts a bit longer again than the UP30/32.

So 2.3L.

I have read some other ppl (non-ev ppl) that didn't bother with the reserve tank.
I'd be a bit skeptical about no-tank in peak start/stop traffic.

2L sounds a reasonable size to have.

The tech specs suggest the UP28 is the quieter of the bunch.

I used Auto One over the counter fittings. The UP28 is in a container where the 12v battery was originally fitted, so no worries with moisture. The RMS engineer mailed the paperwork today, so hopefully blue slip inspection next week. Rear transmission seal leaking; so will replace first. Still way too much vacuum reserve; must adjust one day.

If it's the same as the UP30 then the connector should be a Yazaki 7283-5575-10 or equivalent.

Yeah that looks like it

Shipping alone will be more than any other connector I could shove on there.
Or cut One off a wiring loom from a wreck.

Typical
