Setting timing and stabbing dissy on supercharged mustang
Got a new dizzy for my 95 with vortech system. 6-7 psi boost.
I can't figure out how to get timing set. I've installed dissy in same position old one came out, car runs decent, but doesn't have the power it should. But where I'm confused is when i try to find compression stroke on cylinder one I'm about 180 degrees out.
When I move dissy to this position 0 tdc it won't start. I set dissy again back where original one was and start it and shine timing light and I'm like at 50... First where should I be with a supercharged engine. I must be close car runs and don't backfire and starts easy. But afraid of causing damage to pistons being off.

Find TDC on #1 cyl, even pull the valve cover to verify your on compression stoke if your unsure. Note the marks on balancer, they should be at 0'. If not, your balancer moved.

When i stabbed the dissy originally i made sure the rotor was in the same position and the dissy was in the same location. i assumed this would get me close. after i drove it like this around the block i noticed the engine was getting a little warmer than usual and that it didnt have the power it normally had. i came back and checked timing using timing light. i have marked the 0 and the 10 degree mark.
The marks i made while using timing light are about at the 9-oclock area if looking at the harmonic balancer...
I thought that seemed weird. so i pulled #1 plug and checked for compression. then i noticed, that the rotor was nearly 180 degrees out from facing the #1 plug wire on the rotor. so i pulled dissy and re-installed.. car wouldnt start.. so i went back to where i had it originally and it started right up... but the timing marks when using the timing light are still in the 9 oclock position....
i sure wish i would of checked timing before pulling the dissy out.
This is so strange..... maybe i found the issue with not being able to get it timed right..... check this out... this is the way it has been hooked up since i have gotten it. is this why my timing marks are showing so far off?
