I realize I may across as a bit of a wuss, but I've been curious for some time now to know just how safe chassis dynos are. I always get nervous when I'm on them, thinking that if something were to go wrong there's really nothing I could do about it.

I'm particularly curious about the function of the straps. I assume that if for some reason my car were to come off of the rollers, the straps aren't going to stop much when the tires are spinning at 140+ MPH. It seems more logical that the straps are to keep the tires from being shaken or pulled off of the rollers by restriciting the movement of the vehicle while it's on the rollers, is that correct?

Ultimately, I'd just like to know how likely it is that my car could go flying off a dyno while I'm at the top of fourth gear.

don't worry my car did 185mph on the dyno.

Statistically, I suspect that there are many times more miles covered safely on all the chassis dynos in the world at WOT then on race tracks or streets.

I have driven trucks all my life almost..those 'STRAPS' are very strong..your car weighs very little compared to thousands of pounds of cargo which is strapped down every day all over the world..RELAX..if they are in .......good condition.... and .....tightened properly......., your car is not going anywhere....

that model a's straps broke because the exhaust burnt through them...or so i heard

no biggie. most straps are rated at 5000 lbs each.

Always use chains under the car then attach the straps from the floor to the chains. This way heat or sharp edges will never cause a strap failure, plus shorter straps limits the elasticity, keeping the car more stable and smoothing out the HP/TQ graphs.

I operated a 4 wheel dyno in the Middle east for about a year , the only case that something went wrong was with an evo, that thing jumped from the dyno and i was going to hit one of my fiends but luckly no damage to the car or to my freind . that was the only case out of let me say 500 dyno runs

Don't forget, when you are moving down the highway, you have to stop 3000+ lbs of mass. When you are on a dyno, you only have to stop the mass of the drivetrain from rotating. So it is different than stopping on the road.

I'd be more concerned with not having a DS loop on a car on the dyno than the car itself. If a ds lets loose......

We've had it happen twice, one of many reasons why we discourage spectators.

I've seen that in person on my dad's burb.....wasn't a pretty site. I messed up the Corsa exhaust and some other odds and ends. But, I put my truck on the dyno right after that and nothing was hurt.

That was a close call.

I agree. I had a trucks driveline go south on my dyno before. Not a pretty sound. Aluminum pieces everywhere.
