Blown on dyno!!
My corvette was on the dyno and they pushed it to 6200 rpm's and it shut off then made a nasty knocking sound and the message system said power reserve mode. So we shut it off and checked everything out and smelt a burning smell. We turned it back on and the noise was gone no smell but the check engine light was on. We ran a diagnositc and it came up with ETC mass air malfunction. Does anyone know what that means or what could possibly be wrong with the car. It has patriot performance heads and a high lift cam. It dynoed at 416 rwhp and 404 ft/pounds.

Dyno?
I was only at one dyno place and they had so many blown motors sitting around on the floor that after I watched them dyno a motor, I resolved never to put any of my engines through that. Seems to me like dynoing an engine has to put the equivelant of a bunch of miles on the engine before you even install it and that doesn't make sense to me. Hope yours is okay. Good luck

i love ignorant posts such as these.........all a dyno does is measure the power your car is making. it is actually taking less abuse on one dyno run than it does with day to day driving. sounds to me like you you were at a engine dyno facility designed to test the breaking point of those engines. dont you think if a dyno facility was breaking motors left and right they wouldnt be in business very long?

The only test you should run on your engine is by the seat of your pants.

I'm taking my C5 to ECS in a few weeks to go on the dyno and get tuned. Their machine has a blower that shoots air into the intake to simulate being on the road. Did the place that you went to have a fan? Based on your diagnostic message it sounds as though there was insufficient ram air entering the manifold while it was rev'd up. Just an educated guess on my part.

Following your logic, you shouldn't floor your car either. Flooring your car and running through a gear all the way to the top would be the same as running it on the dyno.

Yes it has 3 large blowers that go into the engine. And it does have the LS1 edit tune. The guys at this shop said that LS1 edit is locked and only can be unlocked by the guys that installed it. Does anyone know if this is true or have any additional advice?

I saw an engine the other day, and asked if it cared whether it was tested on an engine dyno or a chassis dyno. It shrugged its plug wires and said it didn't care.

Actually I think it would be just the reverse on an engine dyno, like starting at full speed, putting on your brakes and holding the gas pedal down also until you either stopped the engine or ? That was the way the one I saw worked, they took the engine up to a set rpm and then started introducing the load until the engine puked and they stopped the test to try to fix the puking. Maybe you are right and all the blown engines I saw in the dyno shop were just hanging around to talk to the dyno tested engines that didn't blow up and all engines puke fluids when you floor them while driving like the one on the dyno I watched that day. I will pass on the dyno test and save my money for something else. I still hope the guy who started this thread didn't hurt anything badly.

I guess I didn't realize how his was dyno tested. I was thinking of the racing engine dyno test I watched.

If the engine blows up on the dyno, it would've eventually blown up if driven hard (like at the drag strip, road racing, etc...).
