We've got many a burn out video so when do you think we will see someone strap the car down to a dyno?
When someone is tired of their tires and wants to ruin them. Not likely the dyno place will have a set of slave Model S tires/wheels.
granted there is lots of torque but they should be able to cross strap it down hard enough to get some stick out of those 21s.
That's not the problem. The problem is that unless the rollers are very large (several metres) it takes only a couple of minutes for the tires to build up enough internal heat to ruin them. That's why slave tires are normally used by competent shops. (I have seen many tires that have dynamometer damage. Most owners were surprised when I asked them if they had put their car on a dynamometer.)
I have never heard of this before. I have run plenty of my cars on a dyno for tuning sessions and never had any tire issues. No sidewall damage, tread issues, or unusual wear. A good buddy of mine is heading to the dyno next month and I planned to take the S and strap it to the dyno. I'll report back with the results. FYI - This is a Mustang dyno that will be used.
The tires always look perfect coming off the dyno. It's only later that problems show up and only the tread is affected. New tires are more likely to have dynamometer damage than half-worn or lower tread depth tires.
this is not true.... I've run plenty of cars on the dyno, no issues... should be interesting to see how the power looks on the dyno, with no gears, I guess you just run it from a slow roll to 130 MPH.... might have to pull the traction control fuse if the car complains....
Small diameter rollers can damage tires due to a very small contact patch. Damage is less likely with the large diameter rollers used on modern Mustang and Dynojet dynos.
Here is the read out from the run (which was in Austin) which was passed around on the Austin Tesla email list.
You'll see horsepower rise with the RPMs. To utilize the best power of an ICE, you'll need to keep the revs high. That's why the model s can get away from ice cars so easily from a standstill. Here's a dyno of an M3.
I think we have a winner for the "required EV audio at low speed" law. Around the 10s mark in the video.
The car was freaking out with multiple error messages afterwards but they all cleared after driving for 30 seconds. It wasn't my car but was a P85.
Video Link PLEASE.... OOPS BAM is the video link. Nice!! Errors are normal with todays stability control. Some cars (MB) need to go through a "button dance" to put them into dyno mode before a pull.
