@@TheCalvinSkinner Thanks! I'll try to do more of that when going over design.

@@chrisdragosh8034 I think somewhere in one of the videos I show which model and the specs of it. These, if I remember right will go to 6k rpm. For a motor dyno I would look at something else or consider a water brake. I do not recommend gearing. I should mention, for an engine dyno, you can find used ones for less than I believe you could build one for.

@@niho12 To purchase what?

@@1992Muz Thanks! I am not sure yet. I may make my own or use YourDyno.

@@nickthomson9723 Thanks! I wanted to run a turbo Vortec 4200 but I worry that it won't survive at 600hp for extended periods of time. So probably a junk yard 5.3... I do have that 5.7L Hemi...

A rough price would be useful.

Thanks! There are some forums with information, though most are still lacking... I am trying but it is hard to find time to show all the design and actually do it.

I am around the gulf coast, usa.

Yeah I have worked through the cost a good bit in detail. Of course there are some unknowns, but not outside the realm of estimating. Some of the cheapest hub dyno systems I have found are still starting above 70k. I will be around 17k with this system. It helps I have machinist friends and work with engine dynos for a living. Steve Morris has some great videos.

@@carsandengineering2022 yeah after watching more of your video, I realized you're after an electrical breaking type dyno, where as Steve's is your typical water-brake (eddy) type dyno, while also more so specific to direct flywheel measured power.

Ah, that makes sense. I was wondering why they are the only ways so shiny.

Thanks! Me too! Haha. Right now I am planning to use QD (type sf or sk) bushings with weld on steel hubs. Weld those hubs to some sort of "cup" or "bowl" shaped hub that will have the bolt pattern to attach the different vehicle hub adapters.

What did they cost ?

I can't wait to see the rest of your build and design process.

Carburetor?

I am not sure about shipping cost. If the shipping was the same, then the chinese models could have saved me around $2k. However, documentation was not clear, communication was difficult, and they had significantly lower speed ratings. The Klam retarders had excellent data sheets and are made of stainless steel. They also have warranties.

I would think so.

3 inch tubing is a little tight but it does fit.

@@carsandengineering2022 thank u!!!!

Hahaha I am not sure this thing will even do much over 160KPH.

@@carsandengineering2022 I think it will make it over 160 mph. One time I was driving my 1989 560SEL White after replacing the spider fuel injection head. And I raced an Infiniti G35 I think I reached around 120 to 140. In my opinion was in bad situation. I think your car after what you done to it it will brake the 160 mph record too easy. Just try once you finish this project. All the best & have a great life. A Mercedes 560 Lover.

I got mine from oreillys. It was not expensive but I had to run a tap through the starter to clean up the threads.

Very interesting, an H pipe wouldn't do anything on a single exhaust. I wonder why they did that.

Thanks! Yes, towards the end of the video I think, I show it. Just had to connect the Microsquirt Tach Out wire to the cars wires by the diagnostic connector.

@@carsandengineering2022 i missed that bit, just re watched the video.

Thank you! I think I am going to try to reverse the timing map out of the EZL since I do not have a dyno.

@@carsandengineering2022 that would be interesting to see, they have quite a map depending on a wide variety of environmental conditions and they store, like the ECU, the last 30 starts / drives. If the EZL is completely reset then the last 30 starts / drives are erased and the unit defaults to a standard map until 30 starts / drives have been completed. This is a FIFO scheme. The original system adjust itself to changes in engine over time

@@inovahightechltd Really? Thats amazing. What feedback is it using to adjust the timing parameters? My car does not have knock sensors. I was hoping to just connect it to a signal generator on my bench and scope it as I change RPM and manifold pressure.

@@carsandengineering2022 the timing is observed by the rear rpm sensor which is a pulse signal off the flywheel. The flywheel has 4 indents at each 90 degree increments. The EZL also creates the TD signal from this input. Further the EZL connects to the Manifold pressure and coolant temp, it is from this combination that the Siemens 16 Bit microcontroller with software written in Assembler back then calculates and determines various environmental and engine conditions. A miss or knocking is picked up via manifold pressure and coolant temp and timing angle from flywheel. Pretty slick system if everything around it works correctly. There were 4 revisions of the EZL from 1986 to 1992, each one will run the engine a bit different.

@@inovahightechltd wow, thanks for the info! Do you have any other option for me to figure out the ignition advance table?
