This is getting far too muddled for me. Please carry on.
I have only one more question for you, if you'll indulge me. Why is the 175 ft lbs ESC called the TQ250 and the 190ft lb model called the TQ300? What, if any, is the numerical significance in those model names?

Of course i was quoting absolute peak max tq gain(even if it was for only 200 rpm).... i wasnt trying to imply that the entire TQ dip was 85 percent gain, im sorry if you missunderstood me on this.
The baseline is the base line, every single time i went on the dyno dynamics the HP was within 1hp, even the day we tested the tq300, i just dont have the baseline overlayed on the max torque run, sorry.
To my knowledge, the model numbers do not stand for Torque. Instead they refer to the maximum engine HP the particular ESC can FLOW.
So the TQ250 can flow enough air to not be a restriction on a 250 Crank hp engine..... This is derived from the CFM at redline.
Now the TQ300 is still in the experimental phase and we are making ground on getting closer to that, what we are finding is that the TQ300 really needs supporting mods to help it get to that goal.... There are some interesting things on the horizon that should help this system.
This isnt to say that as soon as you slap a esc on you are making 250 engine hp, or 300 engine hp for the tq300, it just means that the ESC can flow enough air for that to happen....alot still comes down to tune and gas and "x" and "y"...If the cams fall flat on their face after 6500 obviously it makes it very hard to reach that with minimal boost.
Honestly if you look at it we are getting very close to that, stock crank hp 200hp...equals maybe 170whp(15% DT loss)
Add ESC, 250 engine HP flow.... 212whp at 15% DT loss..... you can see that our engine needs extra help even though the esc is flowing "x" CFM.
Hope that helps to clear things up.
