I've never been around a mustang dyno but we used to dyno a lot on old claytons, don't know if anybody remembers those. If I had to guess probably the easiest to fudge which is why I appreciate the dynojet in addition to it's single roller.
You could get wildly varying results from that by simply varying simple inputs, but that was a long time ago and the details are foggy.
Also I've been saying this whole time there's something wrong with duracels car, 340 is low for the mods and power band is strange.

anyone have a dyno plot from a super flow dyno and then DJ the same car? Just wondering what the delta is between those two.

Will let you guys know what I make on Saturday with the following:
-Stage 3 head with single groove supertech valves and springs
-schrick 280/272 cams and dlc followers
-Full SS exhaust with V1 stepped headers, no cats
-Karbonius Airbox with CSL Map and DME base
Hassan has told me he has made power on a stock engine up to 8800rpm with my cams so I am planning to have him tune to that just to see because the head will take it. If we make power I’ll drop it down to 8600rpm and just plan to replace bearings every 50-60k miles. Nbd lol.
Block leak down tested to only 1-2% loss across all cylinders at 126k miles which is incredible so really looking forward to this.
Will be using a mustang dyno so the numbers will definitely be lower, probably high 340-350 range so I plan to get on a dyno jet at a later time for the actual comparison here since most guys are using dynojet as a reference.

I'm guessing it should make around 350ish on a mustang considering stock head, 360 on a dynojet. We've no idea what kind of power that head will make.
Personally I've never trusted ported heads and it's all black magic to me. I had a head done in the 90s for my gsr by a dude who was allegedly the best in the game and the car always ran like shit.
When my boy papadakis had his shop back in the day, I took a stock b18c head that he swapped out for me and my car was instantly faster. Hopefully this won't be the case for you.

I think he is a bit down on power, 340 on 91 with ported head and same cams as yours is bit low..
I have a local tuner who did 339 on fresh std S54 engine put on Haltech Standalone which it
does not matter for power vs std DME.
DynoJet variation do exist but its minimal. Anyway, there is gain before and after which is most important.
From around 2500k rpms up to about ~6600rpm there is avarage around ~5-9rwhphp gain thru the curve
at 6300rpm there is 0 gain. It seems very little considering the long list of parts.

Anri

Ok, just be careful, because I’ve heard of factory LCA’s bending on occasion.

This is how BMW straps the cars down for shipping too.
