Just so you know, take the numbers you get at Straightline with some perspective. It's a Mustang, so obviously it shoudl read lower than a dynojet.
However I dynoed my bolt-on and F13 car there and according to them made 402 hp. Which basically means they've got it calibrated to read arond what a dynojet would. But they still tell you that you'll get more power on a dynojet comared to theirs.
According to them my F13 car would put down 440 rwhp on Speeds dyno.

According to them my F13 car would put down 440 rwhp on Speeds dyno.As far as calabration, that was done by Mustang Dyno techs when they installed it. Without the proper calibration tools, our abilty to adjust what our dyno reads is limited to being either "Loaded" or "Unloaded." Meaning we can turn off our eddy current generator, and us our dyno as a "Enertia Dyno" just like a DynoJet type dyno. What we have seen when we do that is as much as 17-23% increase in numbers. Thus a car that made 379rwhp with a load, made 443rwhp unloaded. Now every one could agree that those results are over inflated. The reason for this is the difference in mass between a DynoJet rotating mass, and the Mustang dyno rotating mass. We give the 10% horsepower difference as a way to compare. Since most places do not have a loaded type dyno, we give that comparison so that a customer can have a reference against what somebody they know with a similar set up had dyno'd on a DynoJet.
We use our dyno as a tuning tool, not as a bench mark for bragging rights. A machine in which results can be compared against previous measurments to show gains or losses, and to acurately record data.

The best way to do it, is to get a bunch of different cars as possible. That way there is something to compare with apples to apples.
I am curious how my car does against a cam only cars with f13, tr224, and lg cams.
