Hey Tony, Chad, and anyone else who has a powerdyne, I need a quick measurement. The spacer that moves the fan away from the water pump, how long is it (how much does it space the fan out?).

I am in the process of making a custom damper to run a 6.5" 95 GT crank pulley on a Zero balance Romac for my stroker. Problem is I need to move the DIS exciter ring to the front side if the pulley, as it is smaller diameter than the damper and the sensor would not pick it up if I left behind the damper. Now, when I put it forward of the pulley, it gets in the way of the fan. My idea is to get the powerdyne spacer which allows you guys to slip the belt pulley in there for your blowers. That should provide enough room for the exciter.

I just want to know this measurement before i order the part from Powerdyne, as it is DAMN expensive - $86.16 + shipping! Don't loose yours!

Thanks!
Todd

about 3/4" once its threaded on

Thanks for the quick response tony.

My other thought is to have a custom exciter ring made up. This will be ~0.5" larger diameter than stock. I have found a few places to laser cut this and will send a drawing over for them to cost. This would allow me to use it in the stock location, rear of the damper.

I have already made the pulley adapter, not just need to decide which direction I go and make the exciter adapter. This is going to be a nice part, as it will allow me to use explorer accessories on any small block ford with any crank balance. My brother is writing a CNC code for these parts, so we can duplicate if needed by me or others.

i have been eyeing the fms balancer c68 a 5.9" 6.6 lb.neutral. i would need somemore checking.it seems size wise smaller than the standard 5.0 balancer.of course you can grind down the lower water pump bolt. post some pics when you get it setup.please

It is going to be super tight putting the trigger wheel on the engine side of the damper, but best choice. The max clearance to the waterpump bolt is 7" my damper is 6.2", so that leaves me with 0.4" for clearance and offset from the damper body for the trigger to work. I will leave about ~1/8" clearance to bolt and ~1/4" for trigger tooth depth. I will not get to work on this again until Christmas, as my brother's machine shop is 3 hours away and will not trave lagain til the holidays.

Pictures for sure! The pulley was the toughtest part. I am using a stock mustang 94-95 crank pulley (GT). It is 6.5" and just barely slips over the damper body when I turn it around. I then needed to make an 1/8" hub spacer to align to explorer belt plane. I also had to make a new sleeve to center, as the stock hub on the romac was not long enough once I spaced the pulley. Will all make sense with pictures. The Romac I am using is cool, as it has dual keys for the blower.

One step closer to my new engine...
