RUSEFI cheap DIY open source EMS

Just starting to research RUSEFI, and it seams it costs about the same as the Arduino based Speeduino but is more powerful and has more features. The base Frankenstein - ECU shield consists of: 12 channel low side - VNS14NV04 (injectors & solenoids) 6 channel hi side (ignition modules) - TC4427 ...

Speeduino - Arduino based EMS

If anyone is interested, $120ish full open source EMS. The system is up and running, but it's early in it's life so it's still being developed. https://speeduino.com/shop/index.php http://speeduino.com/wiki/index.php/Getting_Started http://speeduino.com/forum/viewtopic.php?f=21&t=221 Videos http...

Re: Gal norbagge bygger dyno, trenger tips :)

Wow, that's a expensive, and it didn't even include material costs. Lucky you have a friend with a free CNC. Right now I'm thinking galvanised steel, but it blobs and clumps, and you have to remove it where there is a tight fit like on shafts. I wonder if a sacrificial anode would be enough. When yo...

Re: Gal norbagge bygger dyno, trenger tips :)

Is it your design, or did you buy plans.

How much would your brake cost to get made.

I don't have much money, and probably couldn't afford such a high quality CNC brake like yours, so I'm trying to find information to make a steel version of a DEPAC, which is very similar to yours.

Re: Gal norbagge bygger dyno, trenger tips :)

What is that black coating

There is one thing that is different in a modern water brake, one of the rotors has an extra pocket/blade, eg rotor has 12 pockets, stator has 13,

I think it is done that way so that only one blade lines up at a time - like a vernier calliper - making it smoother.

Re: Overboostracing/Tommy Luhr's Motorbromsbänk

Steel is not like Iron, it rusts badly, and I don't want to do an Alum absorber because it's too expensive for me. Is 1% enough - 2000L x 1% = 20L which is $100 or 10% - 2000L x 10% = 200L which is $1000 or even more. What's the minimum water for 600hp. People are now talking about a refrigerator he...

Re: Overboostracing/Tommy Luhr's Motorbromsbänk

Sorry for English.

Steel rusts easily, so how do you stop rust.

Do you have water tanks, and how big are they for 600hp.

What seals are on the shaft?

How much clearance was there between the rotor?

Thanks
