gogo Member of team Kittens Member 609 Member For: 21y 15d Location: Melbourne Posted 22/03/06 12:35 AM Share Posted 22/03/06 12:35 AM (edited) Arthur,I suspect you have been sold some BS.without looking too deeply at the physics lets look at what we know people are getting,A stock T will do the 1/4 in approx 14sec with a terminal speed of high 90's (doesn't really matter matter for this rough comparison), with lets say 180rwkw.At 90mph you are travelling at about 40m/sec or 7-8 XR6T car lengthsA modded T with lets say 280rwkw will do low 12's - lets say 12.5secs for the 1/4 (auto - although you are close Arthur!).For the sake of this very rough number exercise lets say that if the stock car averages the 90mph over the last 1.5 seconds of it's run (the amount it is behind the modded car), it will be about 60m behind when the modded car crosses the line or about 10 - 12 car lengths.Difference in power is 100rwkw - which using the 37rwkw/length would be a little under 3 car lengths. This is clearly orders of magnitude out... (for the T - might be true for something like a top fueller that is heavier and longer... )As others have pointed out there are lots and lots of other variables such as where in the rev range - across how much of the range is the extra power made etc, so I would suggest that this as a measure of 1/4 time is useless for the T. Hope this helps! Ben. Edited 22/03/06 12:49 AM by gogo Link to comment Share on other sites More sharing options...

Posted 22/03/06 03:09 AM Share Posted 22/03/06 03:09 AM once I read the title, I knew this was bullsh!t.. so many variables that play different roles, its impossible to make one assumption.these could include weight of cars, manual/auto, driver skills, good/bad takeoff etc etc..anyway as gogo showed above, there is no way to get an exact equasion or way to prove your "experts" theory.
