I've posted this earlier, so I feel like I'm just repeating myself. Pick any RPM point and calculate either torque or hp from the numbers shown on the chart.

Let's take 5k RPM: Looks like 175HP and 210lb-ft.

Calculating for HP with 210lb-ft at 5000rpm gives us: HP = (210 * 5000) / 5252 = 199.9HP.

Calculating for Torque with 175hp at 5000rpm gives us: 175 = (Torque * 5000) / 5252. Torque is then: (175 * 5252) / 5000 = 183.8-ft.


It would be very nice if AVO just label both dyno charts clearly to show US car/fuel and Japanese car/fuel.

Like mines13 said, you would be correct if HP/TQ were on the same scale. At 5k rpm, TQ looks to be closer to 225 ft-lb., not 210.

I would say yes to this question, using 92 Octane gas, air filter replacement into the stock airbox and with the stock exhaust.

Combined with the AVO non resonated cat-back and 7 PSI instead of 5 PSI, this setup could easily make 250WHP using 92 octane gas instead of 230WHP.

250WHP ; 300 Flywheel HP is my goal.

I wonder what this kit makes on 93 octane. Great price tho for a complete kit WITH tune! Awesome work guys!

I would say 7psi and exhaust would net much more than 20whp on this motor. Probably more like 30-40whp.

Again, this is not being disputed. What is, is that you you think the graph does not reflect this, it does. Notice that the torque and horsepower scales are not equal. If they were they would intersect at 5252.

Here is another Dynopak graph where torque and horsepower are on the same scale:

Now look at the graph you referenced, see the difference? :happy0180:

Well that is good news ! It is even better if what you say is true !

Let's say between 255 - 270 wheels HP = 300 - 330 Flywheel HP with this setup :

Avo Turbo Kit
92 octane Gas
7 PSI
Air Filter drop in replacement
Avo non-resonated exhaust

With that kind of power , we are looking for a car that could make the 1/4 mile in about 13.5 seconds at 105 mph. Now we are talking decent numbers for such a good sport car that deserve that.

This is how it should have been done from the factory.

Good job AVO !

Better, if you're a good driver.

It's called "Forced Scaling" which is usually turned on, I think the guys @ AVO were much too excited in putting out the information. That said, if you're used to reading it right, the information isn't inaccurate, just a little more thinking required to get the information.

BTW, that car in your dyno graph was also on our dyno for the "dyno dash" article in Modified Mag if you want to see the difference in readings between the various mainstream dynos.

I think you quoted the wrong guy, I was explaining the same thing from the same point of view.

Yes you were. Didn't say you weren't - I was just a little tickled when you used a dyno chart from an article I was recently pointing out.

Cheers!

@mines13, So you agree that the Japanese graph is inaccurate? The scales not matching causes torque and hp to not cross over at 5252. That isn't really an issue. The issue is that the curves do not correlate to each other. The torque curve indicated is either too high, or the hp curve indicated is too low. AVO cut off the axis labels on either side: left being torque and right being hp. If you go to their Facebook page, you can see the image where the axis labels aren't cut off. Just calculate it, it's wrong. Take down the chart, it's not only confusing, it's also wrong. But it's a moot point for US customers since this chart refers only to a Japanese car with Japanese fuel. I feel like I'm arguing, but it's so obvious to me. I suppose I should just let it be: which I will – after this last post.

Just saw the uncut dyno on Facebook. Holy hell is that confusing!

If I'm seeing it correctly, it is showing WHP but plotting torque at the CRANK....?
