I absolutely agree with the above statement; this dude is challenged, but that wasn't the point which was to demonstrate the smog snap test.
How many of you guys go out and free rev your truck just because "its not hurting it"? I know there is an SAE paper defining the smog snap test, and eluding that it doesn't hurt the motor. SAE would have engineering support in writing the paper which you could say helps validate that there is no immediate damage due to the test, but that doesn't mean I want to do it to my motor. I agree that when running the motor within operating parameters (i.e. incipient to the rev limiter, proper oil pressure, not overheating, no previous motor damage) there will be a safety factor on the components(i.e. it was designed to those parameter). However, I don't think that a select few should be required to take their car (not hybrid), truck,motorcycle, scooter, etc to the limit of the operating parameters (e.g. hitting the rev limiter). Would you agree that there could be a degradation to the life of a motor if it was running at 3200 RPM instead of 2000 RPM? Yes, probably miniscule, but the motor is doing more revs per minute then one that is not performing the test. Also, my truck never gets the pedal to the floor so to see someone else do it wouldn't sit well with me. [Side note: I know that Efi-Live can take care of my issue with the snap test which I am not currently required to due, but its the principal that gets my goat].
Once again I would rather do a OBD test (assuming it just checks for check engine lights and not sensor voltage readings, parameters, etc) compared to the snap test (assuming I can't use Efi-live for some odd reason). Just my thoughts
