I have a 95 Cougar 550, the power is great from around 5000rpm on up but the engagement is at 3000rmp so its slow off the line. What parts do I need to bring the engagement up? I was thinking between 4 and 5 grand.
You need a stiffer primary spring. I would change the spring and add a couple of grams to the front clutch (ex. if you have 50 gram weights go to 51or 52gram weights). My 97 Cougar 550 was a rocket and all I did was change the front spring. It would hit 110 on the speedo on prime conditions.
