I hear stock manual Stang GTs put down 230-233rwhp and 270 rwtq--this is only 10-12% loss--and many say 10% loss is normal for manuals and 15% loss is normal for autos--auto 2k2 maxes only put down about 198 (about 23% loss)--do we have inefficient trannies or what? I think our numbers should be higher

 

for FWD cars, the 'norm' seems to be 15% for sticks, and 20% for autos... Every car/vehicle/manufacturer is different though.
