[other] auto tranny powerloss

["Ryan Schuermann" <rts@nol.net>]

Tell me if I'm drunk, was re-reading the premier issue of MAX Power,
theur Passat 1.8T project car, they add a chip and dyno and claim 
170hp, then go on to say, but this was the automatic transmission so 
you have to add back 15-17%. Did I read this right? They are saying 
that an automatic tranny looses 15-17% over a standard? They go on 
to say so our car was really pulling 190something..I think they 
meant to say we dynoed at the wheels so powertrain(standard OR 
automatic) is a 15-17% loss, so I don't think that's what they 
mean, just trying to state that it was an automatic tranny too??
Anyone else read this?

what is the power loss due to a torque converter? I mean once the 
tranny is engaged, is an auto slower than standard? how much power is 
lost shifting in an anto tranny compared to standard, even say of 
shifting in the auto is reduced to 0.2 seconds, is it neglitible or 
noticable? thanks
