How did I dyno this high? (not that I am complaining)

MattP725 · 08-21-2011, 07:16 PM

I was at performance motorsports this weekend (great trip btw) and my original base was low 330's and after tune I was low 340s (can't remember if it was 342 or 343 but had a 10hp gain).

I have just the mods below...

Now listen I am not complaining but how is this possible? I have the sheet I can scan and upload once I hook up my scanner.

This was on a mustang dyno btw.

That's like easily 35 hp more than what you would usually see... that is a big vartiation in my favor (again not that I am complaining).

I think it was an AWD dyno does that mean anything?

Could just be the type of dyno.
I just got dyno tuned last weekend on a 2wd dyno dynamics machine and I'm at 318.
But I was told that would be about 350(?) on a dynojet.
And of course, we all know that varies by temperature, humidity, etc.
So don't worry about it; just enjoy it.

Just checked... 343

Red__Zed · 08-21-2011, 08:15 PM

Enron dyno.

Their dyno reads high. It's just a number anyways. Trap speed proves real horsepower.

what exactly is funny about that factual statement regarding trap speeds and power?

Yeah, I'm confused.

Well, do you think that if I were to travel down a very long hill and reach a very high top speed; that I would deduce that my car has more "power" than someone who runs a short run on a measuring device? Like a dyno? Trap speeds are measurements like dyno runs. But trap speeds can be very deceptive.... as the example above proves.

do you know of any 1/4 tracks that run down a hill? calculating hp by using the trap speed of a 1/4 mile run and your vehicles weight is very effective.

Trap speed.

As in, your trap speed at the end of the quarter mile shows your true horsepower better than an inflated/improperly configured dyno.
So yes, if I trapped 107mph, and you trapped say, 103mph we can deduce that my car makes more power.
It's not a hard concept, I just think you misread it..

Dyno numbers usually mean nothing unless you have a standard to compare to. It's a tuning tool, not a bragging tool.

To the OP: if other Z's make around that power on that dyno, I think you have nothing to worry about and should be happy

MattP725 · 08-21-2011, 08:45 PM

Yeah I know it is all relative because each dyno is dif, I was just shocked that it was that high.

Eventually we will get to the track and do some runs.
