MustangsRule Posted March 29, 2008 Report Share Posted March 29, 2008 We all are awaiting the metamorphosis from a reasonable mannered 445HP to a stepped up 620RWHP (725 HP converted) SS package. We've also read that SAI will "undo" any previous mods to validate that your car will roll out of their shop with exectly the SS package and only the SS package. Ok, so what's next. If we take our SS to have headers or cams or anything else done to them to get to let's say 725 RWHP., does that mean we have to break down the engine. Can the stock engine handle any HP more than what SAI is delivering? I also read in a prev thread that the internals to the tranny can only handle approx 600 HP. Does that mean that the 725+ SS package is too much for our stock trannys. Just trying to see what the limits are with our current "inventory" before we blow a tranny or an engine since it's just about all on our own dime after installation of these upper SS packages. What do you think............. Link to comment Share on other sites More sharing options...
