Yeah, I wouldn’t trust that dyno. Mustang dynos tend to be lower but also can be calibrated incorrectly. These cars with stock longblocks are pretty consistent for known mods.
Would wonder the timing in the tune also.

I know that this is an old post, but I had my car Dyno'd at the same shop. With a pull when stock, and after doing a 3.4 Whipple. I made 580 torque stock and 648 Torque with the 3.4.

Latest update, after a built engine/cams and ported (OE Blower, Lower Intake, Elbow, and Heads), on 93 pump gas & Boostane, still on stock fuel system and injectors.
Mike Weedin (VMP) done a great job with the tune
and the car made 833rwhp/892rwtq.
Previous power mod's,
next step is to upgrade the fuel system and run it on E-85

Nice numbers! I spoke with the tuner and was told that the torque number is not reading correctly on the dyno at that point time when I was there.
Looks like nobody posts in this thread anymore, but here's my new number after some dyno tuning yesterday, 93 pump gas from Quick Check, no fuel adders.
2014 GT500
TKM sleeved motor, Diamond pistons, CP billet rods, stock crank & block
2" AR headers, no cats, stock mufflers
4.5l Whipple with my own custom inlet, Elliptical TB
headwork & cams
150 PMAS inlet
three Hellcat fuel pumps, staged, return system, Enderle regulator
KB intercooler core DOB Titanic HE, Stewart pump
Stock ecu tuned by me with HPTuners

Very nice.
Do I see 28# boost?
Straight 93 pump, not spiked?
What timing?
Would love to see some pics of the 4.5!

Yes, straight 93, nothing added. Around here all pump gas is E10.
Yes, 28lbs, it may do more, but I haven't tried to go any higher yet.
Timing goes as high as 21°
The blower looks like any other 4.5l, nothing done to the blower at all.
This is in another thread, but basically stock compression, non-sleeved JDM 5.8 with all bolt ons, pump E85, VMP Gen 3 TVS (NOT a 3R) with 15% lower 2.4 upper, 22deg timing.
New blower coming for 2020, stay tuned.

Very nice, congrats thats huge power on pump 93!
Thought it’d be cool to see the custom inlet you mentioned.
-J
Thanks!
The inlets not too pretty, but it did make some gains, along with a the 150mm PMAS. I have the new Whipple TB coming, I may make a custom billet inlet when it gets here. This motor isn't knock limited yet, needs more boost. I drive this car, hardly any e85 around here, so I built the motor for 93. If it was knock limited, e85 or methanol would really help it a lot. This is why boosting stock motors really like e85

What TB are you running?
It does not make sense to me that you are at lower power level with e85 and more timing than pump gas set up above but what do I know.
That is with a 173 VMP MOnoblade, but it will be replaced due to difficulties.
I’m running a 2.65L TVS at 23psi, he is running a 4.5L Whipple twin screw at 28psi.
All relative, and as usual, all based on the combo.

After some winter porting and polishing of the blower and elbow, adding a Metco aux pulley and change out of NGK plugs back to Motorcraft oem plugs gapped at 32 (posted up in another post about spark plug issues) here are my numbers. 93 oct tune by Pete at Performance Dyno in NH.
Nice numbers, Jimmy! Happy to hear the new plugs are working well for you.
Pete is a great guy, Josh too. They did my 14 V6 several years ago. Never had touched one before and had a safe tune that matched all the similar builds and dynos that I could find online. I've got a couple more projects I'll end up hauling over to them to tune for me.

Glad to hear it’s running well.
Looks like you shut the pull down at 6200?
The stock cams will peak at 6500-6700rpm, so you’re leaving a full 500rpm on the table for max power and performance.
Some with previous year GT500s don’t know Ford built in 7000rpm overrev for a reason and I’ve proven it goes faster at the track with higher shift points.

I thought anything over 6200 is dangerous on the 5.8 motor with bolt on mods? 6500 is max for safety concerns?
In a controlled environment like the Dyno, I’d always recommend pulling it to 7000rpm to make sure the fueling is safe.
Stock cranks are usually quoted as good for 1200hp and 7200rpm.
So, it’s safe to pull a modded 5.8 to 7000rpm, just as Ford intended.
Driving/racing is different.
For shift points, yes I’d recommend 6500rpm for your shift light or planned shift point (stock tachs suck to read when driving hard), as there will always be mechanical overrev or clutch flare, nothing you can do there.

Pulled my last Dyno sheet, seems my peak power was made at 6620rpm and you were spot on with your comments, may be add'l power that was left on the table.
