Nice, are you using Simhub to run the transducers and If so do you like It at the 50watts or do you need more power?
Sim racing can be as little 2000 al the way to over 50,000 depends how deep you want to dive, The more money you spend the better the immersion will be.
Yeah I use Simhub. I also use the vocore screen and leds in a 3d printed case for a dashboard, and use it for that as well.
The argument for more power would be the same as more torque for a direct drive wheelbase. The fine details are there, road texture, wheel slip etc. are all perfectly acceptable with the 50 watt transducers, but more power would give you more dynamic range. So the additional power would only be for harder impact, crashes etc.
They recently released a 300 watt version of the transducers I have, and I have been considering upgrading the ones for the wheels.
The wheels are the most important and having an individual transducer for every wheel lets you know what each wheel is doing. For everything else, I could probably get away with the 35 watt version.
The engine effects are a nice touch, but it's really only noticeable at idle and when on the limiter. I only run that at 50%. Being able to feel the trans bang into gear is nice, but it really didn't need it's own transducer, that effect could have come from the same transducer as the engine vibration.
The way I have accel/decel configured those only output for hard launches, hard stops and crashes, but that can be configured to output to the wheels. I probably could have went with 5 channels and not really notice much difference.
