Patrick, how much power do you have and how much money do you have in the engine ?

I wanted a "true, honest reading," so I had it dyno'd with the side pipes attached, and water pump cranking. That number was 475HP. If you pulled the engine out and put it on a dyno with open primaries, the numbers would likely be in the low 500's. IMO, a dyno reading that doesn't at least try and duplicate the running condition of the engine is blatantly misleading. As I said before, blykins could probably clone my engine for $15k, or right around that number, maybe less... as I have some overpriced parts in her that aren't really necessary.

Thats why I prefer using a chassis dyno vs engine dyno. More real world, especially the Mustang brand. You can also break-in a engine on the chassis dyno and, it's much,.....cheaper to tune than a engine dyno.

Patrick, why did you pay to have your engine dynode, just for tuning and not for power results ?

In the scheme of your FE's build costs, the cost to dyno it is next to nothing. And with a SFT cam engine, the break-in is a bit trickier than with a hydraulic. Having it broken in, and then checked on a dyno, was just "reasonably prudent," as we like to say.

Stuffing it in under a Cobra's hood steals a few more horsepower, so I generally quote my number as an "honest 450HP," and she is the weak sister around here,

although I would bet my car has a slightly higher number today than it did when I took delivery. I've spent a decade learning exactly what it likes, and she runs absolutely phenomenally at WOT, slow cruising and all points in between. And I don't know what I'd do with an extra 50 or 100 HP anyway, since she breaks loose now on hard acceleration at just about any street speed.

They chassis dyno is a great tool. Why spend $500-$1,000 on a engine dyno, when most good,.... tuners with a chassis dyno is $75 per hr.

But, if a motor is a very high power machine and it's critical to get the best tuning, especially fuel delivery, a engine dyno is preferred.

My builder had an engine dyno, so the cost was next to nothing. As I recall, it was less than a hundred bucks, if it was broken out of the price at all.

... and that's really not anything special. Several of the builders on 332-428 Ford FE Engine Forum like to post vids of their dyno pulls. Here, I pulled up Barry's because he came to mind first: https://www.youtube.com/user/Survival427FE?feature=mhee I think if you had any of those guys build you an engine they'd throw in a fast dyno pull for next to nothing.
