It says in my manual that the max Hp for my 94 MachZ clutch setting should be at 7800rpm'.
She tops out around 9000rpm'......(she does 200kph at that range) How do i set my clutch for it too max out at the 7800rpm mark!?
And will it go faster?
Everything is stock except for a aftermarket MBRP Muffler!!!

the factory adjustment only changes the max rpm about 500rpm. if its going all the way up to 9000rpm, your belt might be bad or the clutch springs are worn out.

will it be better to rebuild my clutch or is it better too buy a aftermarket clutch? say a Comet Clucth perhaps?

Start by making sure that the belt is not too thin (worn).
Then check that it is riding up at the top of the secondary (1/8" of the belt out of the top)
If both of these are right, then check where the spring of the secondary is set (1,2,3,4,5) hole on the outer plate.
As the spring is moved forward or back from the center (#3), the peak engine rpms will go up or down by 2-300 rpm.
At what rpm is the primary (engine) clutch engaging?
Should be around 3400/3800 rpm stock.
