While we're on the topic of the IX putting down better numbers with the same mods, what would be the best guess of what you could expect from a IX with the same mods?

I agree with the others who stated these numbers are about on par with DynoDynamics or MustangDyno.

If these numbers are from a Dynojet, I would have to believe there is an underyling problem, such as a boost leak or a poor tune.

 

Boost was set at 21.5psi I think but, on the defi gauge in my car is says 1.5 I thought that was equivalent to 22psi..dunno but, yea 21.5

 

1.5 bar = 22.05 psi

edit: modyp is right

1 bar = 14.5037738 pounds per square inch
So he is at 21.755 psi ~ 1.5 bar.

 

seems low to me, and as stated befroe, it could be any number of things or combinations of factors..

 

No, we are not on that topic.

 

I had almost the exact mods as you, minus the injectors, and on CFT's Mustang dyno I did 337hp/339tq. And mine was tuned by Jestr .

How much boost are you running?

(And I know of the "issue" with CFT's dyno, but I don't exactly what it is, that it doesn't read like a normal Mustang dyno or something.)

Edit:

And as a reference, I dynoed 246hp/247tq on the same dyno stock w/ k&n drop in.

 

Well, from what I recall I think AMS said their dyno is pretty accurate..So I guess 301whp is my whp# don't matter though I can still keep up with a 500hp C6 vette!!

 

I dynoed at 289 whp and 277 wtq at AMS (on their dynomite dyno) with my 03 Evo. My mods were xede (with a 91 octane stage 1 basemap), 2.7 inch dp and 3 inch invidia exhaust (including a megan resonated pipe). Boost was at ~22 psi.

 

The reason your number is low is the low boost. 20 psi is stock boost on an 05 Evo. I do not know what it is on an 03-04, but I guess it is 19 psi. Raise your boost by 2 psi and your numbers should go up to 325-330. That is where your car should be with tbe, cams, intake.

 

I had the XEDE on but, it didn't work out with my car..Is your car cammed? If not those are pretty good#s..

 

reads like a dynojet

 

No my car is not cammed. The numbers in my sig were on a dynojet on 91 octane gas.

 

It's not an issue, really. It's just that it reads like a Dynojet as Evoryder mentioned. You can see this in your stock numbers. Most 03s didn't make near that much power in stock form even on a Dynojet, much less a Mustang Dyno. Hell, my 05 made those same numbers on a Dynojet in 50-degree weather, so that gives you a good comparison, and I ran 13.1@104, which is very rare for a stock 03. On regular Mustang dyno's, you would see right around 200-205whp on a stock 03.

Doesn't matter, though, because you got before and after numbers, so you know you had great gains.

 

Not anymore it doesnt, its been recalibrated.. Procco Evo recently went on that dyno and made 675 and went to Fynetune in miami and make 73x.xx on their dynojet..
