Explain my dyno numbers

I ran my Terminator yesterday on a dyno and I'm having a hard time explaining my numbers. A basic rundown of the car is as follows:
54,xxx miles
JLT ram air intake
Moroso coolant expansion tank
Cobra engineering head cooling mod
EGR delete
Manley H-tuff series connecting rods
Crank balanced and polished
ARP rod bolts
ARP head studs
Exedy mach 600 stage 2 clutch
Exedy lightweight racing flywheel
Magnaflow cat back with magna packs
MGW short throw shifter
SCT livewire tuner
In theory I should basically be running stock numbers, but she pumped out 480 hp 450 torque. Any ideas how my numbers would be so high? (Not complaining obviously)

Blower must be pullied and or ported. Higher than stock compression.

Stock pulley on upper and lower

When the motor was put back together they used the stock pistons with new rings

Is it a Happy Dyno-jet?

It was a PowerDyne Mustang dynamometer. Numbers were running true all day

One thing I notice....There's no correction factor being applied.....that's the reason it shows the "with WCF" is identical to the actual number. The chance of that happening in real life is between slim and none.....and slim just left town.

Ask for the sheet again and make sure they apply an SAE correction.

I'll be running again next month and I'll ask for the correction. I ran the data in a correction calculator for yesterday's weather here. I'm still confused how it would be putting down these numbers at 6400'

Take it to the track. .if it traps 113 mph you'll know youre making stock power.

Yep, take it to the track. Easiest and quickest way to confirm the reported numbers. So you do have a tune, based on the inclusion of the SCT livewire tuner in your list of mods. If you do have a stock upper and lower pulley, you could see around 425-430rwhp (SAE Corrected) with a good tune. But again, take it to a track to see what you trap, like @gimmie11s said.

I'm sure my track time would be terrible with the vast amount of wheel hop I have. Around here I'd probably have to wait until around May to get to a track. Traction..... I need that so bad

I haven't bothered getting a tune on the SCT yet. Figured I'd rather wait until I'm done building, because I have no shops in close vicinity.

Ah, so you have the tuner but no tune yet?

Yes, it has been a build in progress. Just thought I would see where she was at. Being a convertible it has been a traction problem since day one.

These things were underrated by ford from the beginning. Yours might be one of the ones that just makes way more than the rating.

as mentioned somethings off with the correction factor, the raw numbers vs corrected numbers matching exactly has basically a 0% chance of occurring naturally. In 60 degree air my procharged car made raw numbers around 25hp more than the corrected hp.

Regardless of correction the car has some serious balls!

what happened to the motor that you put in new rods and crank?

Beefed up the bottom end for more power.

Humble brag?

Do you have a pic of the whole sheet? Where did you get it done at? Maybe others have been to your dyno and can tell you if the dyno was happy or not?
