Iwas wondering about those numbers you got with those mods until I noticed that the graph was converted to flywheel horsepower. Never saw that before on a dyno sheet. Do you know what loss correction factor they used? Thanks.

Those numbers are not converted flywheel from the engine - the Dynapak states "flywheel" because it's measured from the flywheel of the Dynapak. The Dynapak removes the wheels and measures actual torque from the axle, then uses the rear-end gears to convert to rwtq and rwhp.

What is the value of that other than to give you a higher number? The numbers would be lower driving the actual wheels that are on the car. I don't understand. Please explain.

With the smoothing set to 5, also have him use SAE correction. The overall result will be lower numbers, but truer.

i think it would help this thread if everyone would list the year and model of their car with the mods when posting the dyno sheet

That's the thing.....you're looking at it from the "wrong" view point. These machines (Dynojet, Dyno-mite, Dynapak, etc....) are devices for tuning, each measuring and calculting hp & torque differently. The dynojet IS NOT necessarily the most standard or correct device for measuring hp/tq, it's just the most popular.

I do understand that that they are just tuning tools. I've had a few before and afters done on my car, also (see sig). I do know that the Dynojet and Mustang (which gives lower readings than the Dynojet) seem to be the most prevalent, and I do understand how both of those work. I had just never heard of the Dynapak before. Interesting.... What bothers me on dyno numbers being quoted car-to-car, is that it's rarely an "apples-to-apples" comparison, as dynos are different. Also, some tuners run SAE corrections, some Standard uncorrected, some change smoothing numbers, etc., all of which can fairly dramatically change power and torque ourput numbers, thereby making many of them meaningless for comparison purposes. As an example, I've seen really high output numbers quoted and then when you look at track times for those same cars, those dyno numbers seem bogus (and probably are). And, on the other hand, some quote relatively low numbers, but the car burns up the track. Too bad there'e not some overall standards or correction factors in place to standardize the numbers from different dyno manufacturers, or, tuners wouldn't play with the software to make their work appear better than it actually is.
