Is it safe to use a dyno?

[Z Boy]

This is probably an absolutely rediculous question but I'm booked in to have my car on the dyno tomorrow to see what power it's making and I remember when I had my MOT they could not put it on the brake rollers because of the diff, how is that any different to the rollers on a rolling road!?

 

Also, what kind of power and torque should I expect to get at the wheels? It'll be a dyno dynamics roller.

Should be fine. I'm going with the MLR lot when they next arrange a day.

 

What rollers are you going to?

No worries

 

Expect 230-235 HP at the wheels

I'm sure it is safe but dynos that attach to hubs are perhaps safer.

 

Not really worth spending the cash unless your having it tuned at the same time, all it will tell you is what your car makes on that particular dyno at that particular time.

 

Hope it goes well.

I'm just doing it to show the MLR boys what a real engine sounds like
