I was being precise. 5252 is the correct #. But I guess I can live with 5250. 
When I said "supposed" to, it mean that it "would" intersect at that exact point IF the Horsepower and Toque axises were scaled the same. As you can see on the dynograph, the HP is scaled 0-450hp and TQ is scaled 0-550ft/lbs.
That is why the slope of the torque curve is higher than that of the horsepower curve. Hense an earlier intersect point.
Now, the reason they are scaled like that on Axis's dynograph, is precisely because of what Mike said. Sort of.

Well i hate to point it out to you mike but you might have missed it due to the fact your eyes are accustomed to seeing thru fog that is as dense as steel. So next time just stare at it for a while until it comes into focus.

1) Why do the torque and horsepower numbers cross at 4500? I thought they were suppose to cross at 5250, maybe I am missing something? An incorrect calibration on the dyno or maybe the computer overlayed the torque and horsepower incorrectly.
As an CAD GUI designer by profession it is very hard to make a clear and informative system for customers to use and understand easily. Dyno Dynamics has done a good job, as a suggestion could you set the curve intersection to 5252. Might make it easier to compare curves between dynos. That is all I was trying to get at. And Alex helped me clear up the incorrect value I used of 5250. You always learn something new.
As for his comment regarding the results being lean, I am confused given the AFR graphs of all the I-Speed tuned cars we've tested/retuned.

Good morning, gentleman. We can take a look at why the torque and horsepower curves must meet at 5252 RPM:
HP = (torque * RPM) / 5252
horsepower equals torque multiplied by RPM, then divided by 5252.
Plugging in actual measured numbers for the variables will always result in curves that meet at 5252 RPM. It isn't an arbitrary number or a coincidence. The curves intersect at that figure because of the way horsepower is calculated.

We are not in the lying business. Ron is probably the most helpful person I can think of in the Subaru community and saying otherwise or implying something in a snide way is just downright rude.

What you are saying would be more believeable if you told us up front that the info had been manipulated.

It seems to me that I-Speed and you just wanted to find fault where there isnt any... So congrats? :banana: It seemed to work well.

EDIT: to make more of a point, the dyno graph... Has the motor that i posted pics of. Do you see why I posted the graphs now? Motor that I posted about initially, dyno graph of a car with that motor... Are you following me? Had personal info, i deleted and put '2.35' in there for your amusement.

I don't see where I-Speed was trying to find fault or call foul play as Shiv describes? We had some questions and we got answers. To make it even clearer I-Speed USA and skywalker are part of I-Speed USA.
Mike, from Axis Power, we really do appreciate your time in answering our questions. Hopefully you will see in our posts we are not trying to find fault. We just ask very direct questions, as we want direct answers. That is how we are, some poeple percieve those questions in a totally different way.
Cheers,
Bill Knose

Back on topic,
nice motor, good price, nice numbers. You can post a picture of Mickey Mouse on the plot for all I care. I like your 2.4 motor, but the price on this one is hard to beat. Plus, for most of us, this motor will easily meet our power requirements.

Mike/Axis - Can you post all of the other bits and pieces that were on this car like a listed breakdown of the parts, I would think this may also help folks understand the power of this thing and how it was derived.

how about this everyone
im the fastest car ever cause shiv used his magical mojo powers to infuse my block with the power of 10,000 magical gnomes.
(stop *****ing at each other over stupid pride, sit down shut up and make something better if your soo damn butt hurt about it)
ANd that comment IS directed at EVERYONE in this thread who got butt hurt.
(side note: this thread can be either very prodductive or very childish lets keep it on the productive side of things people)
And axxis has a bad *** block and motor. As does ispeed, and we all know shiv is like gandlaf the grey with a dyno and laptop.

Ported heads, valve train upgrade, jun cams, 2.35 LITER MOTOR, a ginormous t3/t4 hybrid, our custom fuel system, our custom intercooler/piping.
BUT, I will say this. That car is very customized and can make 550whp with the right tuning and gas. It did make 412 whp when we mixed a lil 100 octane to the mix. The 358 was at 19-20 psi and on pump gas (and on a dyno dynamics dyno, Shiv pointed out that would be 400whp on a dynojet Not too shabby for pump gas.
So to conclude. This block with other motor building mods will handle the power one would need w out purchasing our 2.4 stroker motor. I consider that more of a race motor.
