Lets see, where do I start,
1) I thought I did say all drive line losses were guesses? Oh yep post 1.
2)You say I pulled 30% out of nowhere, then you go and discredit what I learned at university, where I got the 30% from. Really? Ok
3)Where precisely do you get your figures from?, the internet?, guessing? or from "tuning shops who may have a vested interest in bigger numbers." ? And all of that is more valid than What I learned from someone with a PhD in engineering in college!!
4) I pulled as much different data from as many different dynos on stock cars as i could find to show how much less most cars make when on the chasis dyno
5) the supra auto box is good, as an engineer I agree (what are you by the way? Since you obviously know more than me or my professor, or all of the equipment we use), but there is nothing amazing about the box to indicate it has higher efficiencies than Manual transmissions. so you get to pluck a higher efficiency number out of the air ?
