Where the 255/295 numbers came from--I don't see them anywhere in the video...
If the car they used is an auto, then my 5spd with the same mods would put down more power. That was just a guess of what a stick with those mods would dyno at.

Dead stock PI 5-speed GTs in decent tune will turn 220 rwHP, give or take 5. I have seen a half dozen or more on the rollers, ranging from a ratty 2001 (with an "eBay" HAI) that managed to churn out just 206, to a very clean Bullitt that put down 228. Most come in so close to 220 that you could set your watch by it. On a dyno in 4th gear (3rd for an auto, with the tranny locked) auto or 5-speed makes no difference.

A good (not great, good) and "safe" tune optimised for 93 octane will bring that to 235, maybe 238, with no other mods. Individualise the AFR and timing for a particular engine--and make a video of the best run--and 244 is not a major challenge--with the stock intake.

With the mods listed in my signature and a fully tweaked tune I got 262/305 (best of 4 runs, 256 to 262)...

I have an auto with a MAC CAI, 75mm TB, Accufab plenum, catted X-Pipe and a canned SCT 93 tune I put down 224/255 on a Dyno-Jet. Seemed low, and disappointing, to me but the more people I speak to the more I think it's about right for what I have .

Still disappointing...

That is quite low, do you have an aftermarket 2-1/2" catback?

What did the AFRs look like?

Was the tranny locked into 3rd gear when the pulls were made?

Some handhelds have a "dyno" mode setting for the autos. Delta Force Special Forces calls it 3rd Gear Lock:

Well, crap. Now you've depressed me Cliff

I asked this same question here a couple of months ago:
https://www.moddedmustangs.com/forums...-i-making.html
...and I was feeling better towards the end.. sigh.

As far as the exhaust is concerned, I forgot to add that I have BBK shorties but the rest of the exhaust is an unknown. No manufacturer ID anywhere including the catted X-Pipe. For all I know it could be stock after the cat's.
What is the stock diameter? I could measure what's installed.

If I remember correctly, stock diameter is 2.25 inches for the exhaust.

That's correct, and most aftermarkets are the 2.5in

2-1/4" to 2-1/2" ID doesn't sound like much however it is +12% larger in flow area--enough to be less restrictive without slowing the gas velocity so much as to affect anything...

I've never been to sure how much a larger diameter affected the gas velocity by added a 1/4 in. of diameter. Nice to know it shouldn't slow it down too much.

idk where i'm at. never dynoed it. yet. but i wouldn't be surprised to be around 250-260 give or take a few.

i kinda just go off of what i've beaten lol look up their "stock" numbers and depending if i kno there are mods, add a few HP and kno i'm within a certain amount of HP of them (this of course is when i win - and i do account for the 4.10's).

but what i've read from many ppl on here and other forums and the general consensus is that CAI's don't do much, especially by themselves. add a TB/Plenum and open that exhaust up w/ an O/R mid pipe and of course gears w/ a good tune.
