Dyno Charts Rock! Almost stock GT!

[94-302-vert]

I have only Dyno'd one vehicle in my life, a 2000 Dodge dakota v8 with a few small mods.

I dyno'd like 220 as driven in, 216 with no air cleaner, then with short belt and no air cleaner 229, probably would ahve beat my goal of 230 with the air cleaner and short belt. So I would say that could be a small difference.

I think something is definitely off. Did anyone look at the dyno graph? Those are the wierdest looking curves that I have seen. They look like bubbles, completely rounded over. Nothing like any other dyno curve I have seen before.

Maybe you got a bad pass, or the dyno is crap. Ya, ya, ya they claim it's one of the most accurate. Bla, bla, bla. What would you say if you were trying to sell dyno pulls at a track day? That particular one could be toast.

Did you look at anyone else's dyno chart that day? Did their's look equally bizzare?

4,900 as a shift point sounds REALLY wrong.

i noticed that too, but i realized thats just tracing the rpm's dropping back down after he let off, usually they cut the graph off down there so thats why it looks different

why is that? When i race now, i do much better, look at the chart that's where the power starts to drop significantly, I think around 5k rpm is a perfect shift point. REMEBER, this stang is basically stock!
... and yess they let off around 5500 rmp or they limited the dyno to that for my run or something like that, so that's why it looks like a bubble or whatever.

...and i personally think that had we not been stupid by taking the exhaust and air filter out, we could have picked up around 10 hp more
