Hey 5spd GT, you said that the 93 mustang really does have 225 hp? Its not really 205? Why in the world would Ford do that? This whole time i thought my friends car had 205 hp stock and every mod we put on we would add that to 205 hp.
Because the following year Ford released the Sn-95 body style... and to clear the hood the intake was made a bit more restrictive...hence the 10 horsepower loss (to 215hp for the 94-95 models)...and Ford being the smart people they are...
...knocked down the 93 model horsepower to 205 because they couldn't fathom the new body style coming out "strong" with less power than the previous model...Ford said they changed the way they measured power and 205 was closer to the actual output of the 5.0...but dyno test have proven this is not true with 185-195rwhp being put down by 87-93 5.0's...
To further this truth...this is straight out of a book I have which is titled "Mustang 5.0 & 4.6"...
"...Ford lowered the horsepower number to 205 for 1993 only. The engine didn't just lose horsepower; Ford's official line was that the method by which it rated horsepower had been changed and that this was really a more accurate number."
Down the page it talks about the hints that it was a marketing ploy because Ford could not fathom putting the new model car (94+) with 10hp less than the previous model...Ford denies this...but it makes complete sense...
Instead of the 04 Viper having 500hp...how would you like to buy a 05 Viper with 475hp....same principle applies...
87-93 cars dyno probably no more than 5rwhp apart...because of the little changes like slightly different cam designs, speed density, maf, etc...
93 cars came with Hypereutic pistons so some people say this is the reason for the change but actually are lighter than the forged pistons (87-92) so actually the hyper pistons might be good for another horsepower
Hope this helps
