Bosch LPS002 Interia Project from South Africa

Greetings Everyone

My name is Brendan from South Africa and I recently acquired a well used Bosch LPS 002 dyno and it will be getting a lot of love to get it back in use for development of some products I manufacture.

I will ask a few questions about inertia dyno's and the software as I will definitely be utilizing the "Your Dyno" Software and Hardware
Really love that the software is so configurable along with add-on's and that allows for inputs from external sensors.

This is not commonly found on locally manufactured dyno's in my country which are Dastek, MrTurbo and Hyper Power.

As you can see it needs a good cleaning with a nice coat of paint!

Thanks a ton, look forward to contributing to the forum as I learn.
I am missing a few things such as the bellows and the guides for the ends of the center raiser between the rollers.
Hopefully I can get them made up or I can buy them from someone that has spares
I do need to know if the Your Dyno Control unit requires in the setup the full weight of both entire rollers (front and back rollers) and the weight on the side to give an accurate reading on inertia runs.

I haven’t been able to test yet, but as far as i could find inertia should be around 13,5.

Would be awesome to get an answer as to what the YourDyno hardware requires, total weight, an estimate or just the side weight of the front roller.

Hi,

You need to enter the total Moment of intertia into YourDyno. YourDyno does not actually care or know how that MOI is generated. There are some MOI calculators online that should get you in the ball park. Remember you need to account for the car's wheels and drive train too. So if you start from scratch the easiest is to take the car to another dyno and then go back to your dyno and change the MOI in the software until the results match. Make sure to do the same type of run of course (including retardation).

Hi Brendan

Im also from South Africa and have 2 of these LPS002 dynos.

I have actually increased the weight of my flywheel to accommodate higher HP vehicles. With yourdyno DAQ it works very well. I have had no issues with it at all.

Shaheenem, i’ve seen interesting write ups from you!

 

what have you done to the trigger wheel? Also what MOI did you set it at?

Shaheenem thats great to hear you are using the same Dyno and have had success in getting it to work with the Your Dyno kit.
Have you done anything to the rollers to get them to have more grip and have you changed the bearings out as I would like to change mine before installation.

Hi, i have the same dyno. Would you mind sharing more info on how you added more weight if you dont mind, i might be wanting to do the same.

Kind regards

@michael We had an additional plate cut and bolted onto the existing flywheel. Then sent for dynamic balancing.

Brendan,

How is the dyno treating you? Still happy with it?

Hey Tuur
Yeah still using it daily
I sprayed bin liner on the rollers and I must say that if strap the vehicles right (more forward onto the weighted flywheel roller) the dyno can read very accurately up to around 600HP.
I can agree with Shaheen that the flywheel needs to be heavier to allow cars with big turbos or diesels to load up a bit more and produce correct readings. I have considered purchasing a billet of iron and bolting it to the side of the current flywheel and getting it balanced.
I'm still using the two bellows and plates I got from your LPS002.
They work perfectly, im still just not sure how the plumbing works with the solenoid and the valve to operate the riser.
I just use an air line connected to a compressor.
