Stage 1 Finally Installed

Not trying to make a point really just opening up a discussion....consider the graphs I have attached of a stock evo I recently dynoed on our Dyno Dynamics Dyno
DD has a function that is able to give an approximate flywheel horse power
A run was made and two graphs were created, the first one in normal wheel horsepower mode
and the second in approximate flywheel hp mode
DD has a function that is able to give an approximate flywheel horse power
the latter run is obviously the higher figured graph.....
Notice how close to the factory figure of 271 hp and 273 ftlb torque the dynos results in this mode was able to come
This has not only been observed on Mitsubishi's but Subarus, Chevys, Fords, Volvos, Hummers, Toyotas, Hondas and so on and so on.....
My question is this....If a Dyno Dynamics Dyno whp figure is so low, as it has been suggested many times, how is it that in approx flywheel horse power mode it is able to get so close to the manufacturers claimed power at the brochure?

I honestly always doubted the power levels quoted by DD's... But that flywheel comparison was the last piece of the puzzle I needed. Dynojet = Ownzed

More people use the dynojet numbers which is why I mentioned them. In end it about how much WHP was gained and how safe the tune is regardless of the DYNO reads low or high

From what I've deduced in looking at both DD and DJ graphs is that it is pretty much futile to try to compare numbers generated from either dyno. It's pretty clear that they put different loads on the engine at different RPMs, so it definitely ends up being an apples-to-oranges comparison.
I'm not really sure why the approximated flywheel hp is such a big deal ... all it means is that DD has been able to estimate close to the correct conversion factor. In the end the only thing that matters to me is TQ @ the wheels.

I guess what I was trying to say is that with the variance from Evo to Evo, how do you know that they conversion factor just didn't "happen to be correct" for that particular Evo? Does DD use a static number or does the software actually attempt to adjust that conversion factor based on some set of variables? One of the things I've noticed about the DD dyno curves is that they generally show less torque than hp, whereas the DJ curves show more torque earlier and less HP up top. Now since the numbers 
advertises show more torque than HP, how does the DD software "correct" for the readings it is getting to end up close to the factory crank numbers?
I mean I could take my stock baseline and divide it into the stock figure and get the conversion factor for my car, which in my case would be (271/205 = 1.322). Now, theoretically you could use that conversion factor for any other Evo on that dyno. Not only that, but again, theoretically, I could use that number to estimate my current whp, which would then be (286*1.322 = 378hp). Interestingly close to the stated FQ-400 numbers, hehe. ...but I digress ... obviously all of this is a bunch of mumbo-jumbo, since whatever power you are able to put down at the wheels while driving on the road is all that matters (that's what my reference to TQ @ the wheels was alluding to).
Anyways, I'm not trying to pick a fight here, nor trying to hijack the thread ... just pointing out some things I've noticed. IMO after it's all said and done Vishnu Stage 1 = how the Evo should have come from the factory

Time to go home...Ludikraut, I have the answers for you ...I just don't have the time.....If people want to we can resume tomorrow???If not please tell me and I will shut the H*** up...
No worries Andrew ... not everyone is stuck being a keyboard jockey all day like me. You've got a business to run, but keep the info coming when you can ... I'm always looking to get edumecated
