i would rather look at corrected numers. it helps compare setups in different areas. for example, when corrected my numbers actually drop...someone in colorado would probably show bigger numbers by correcting. the point is to try and calculate it to where both runs were in identical conditions.

My truck has been on the dyno 5 times. I'm one of those guys that went to a different dyno, because numbers weren't right after having the converter to lock. 329 unlocked & then on same dyno made 310 locked. So I new something was wrong with either the dyno or the operator.
If I change something on my truck it will be back on the dyno.
This is the world wide web can, we really trust what people say on here.

If a car or truck puts down "X" rwhp, you can have an idea of what it can do in the 1/4.

If a car or truck runs a particular time in the 1/4, doesn't mean it can't get its *** drug by a car or truck .5 sec slower on the street.

This whole thought of dyno numbers being worthless reminds of me of "its not the size, its the motion of the ocean"...lol

That's why timeslips don't just include ET, they also have MPH, 60', 330' etc.

You can tell a lot more about how a vehicle runs from a timeslip than a dyno sheet.

I haven't made an offical, NHRA sanctioned 1/4 mi pass in over a decade. But I was aware that a timeslip included more information than time. Like I said, peak power output at the rear wheels gives you an IDEA of what a vehicle can do in the 1/4. I don't see where I said it was a better source of information of 1/4 mi performance.

I disagree. A dyno sheet contains more information than "peak power numbers". At least mine does. And a dyno run gives you a ton more information than a timeslip does.

Im not saying peak numbers from a dyno sheet are the best assessment of a vehicle's performance. But they aren't worthless.

I'm not going to disagree with you there, but the information you get from a dyno doesn't necessarily equate to real world performance.

It obviously doesn't take into account things like the weight of the vehicle, suspension setup, whether it has traction or not, wind resistance, etc., so while sometimes you can base pretty well off of a dyno graph how a vehicle will perform, other times it will be completely off.

I think we can all agree that dynos are a great tuning tool, and great for telling how an engine performs, but you get more useful information about how the vehicle as a whole package performs from a timeslip.
