I am going to get some under drive pullies, just wanting to check out some pictures, if anyone has them? I am thinking of getting some bbk or march ones. Wouldnt I have to buy a harmonic balancer though?
What other mods do you have that would call for pullies?
Just get the crank pulley/balancer from ASP the others are not needed.
On my 1995 Thunderbird:
On my 1995 Mark VIII LSC:
Because the Mark has a heavily electrical dependent system, ask anyone with the 3 piece set up how dim their headlights are at a light. Alternator strain amongst other electrical components is bad.
Both of my vehicles run fine, too!My car's fine.
Which states that it won't fit the 1996-2001 Cobra, so it probably won't work on a Mark VIII either. :shifty:
I'll take that bet.
The pulley on a Cobra or Mark VIII doesn't protrude that much on the side towards the alternator, it's actually recessed.
If the March 110 pulley fits on your Thunderbird alternator, it also won't work on a Mark VIII......
And overdriving the alternator pulley on a DOHC raises another issue, over-revving the alternator.
You are just never satisfied, are you?
FWIW, I've done several things on vehicles that people said wouldn't work - these pullies are just another example, IMHO. I just have to admit that I have never changed the pulley on the DOHC alternator -- yet. But you will be the first to know when I do and how it worked out.
I've also never burned an alternator up by over-revving, either. Have you ever seen an alternator fly apart, bearings burn up, or any other over-revving mayhem?
But as I've always said, everyone is welcome to do whatever they want - I have and do! lol
And do you shift at 7,000 rpms like DLF does? My bet is no. Not many here do.
I run mine up to 7000 everyday. Did it with the stock damper and also with march underdrive damper. I will be making an overdrive alt pulley to get rpms back up abit.
DLF is correct...
With the 1.93" (49mm) Powermaster 114 pulley I have installed now, it does about 1700 @ 650 rpm and 18000 @ 7000 rpm.
If you used a 1.81" (46mm) Powermaster 175 pulley, it would be 1800 @ 650 rpm and 19000 @ 7000 rpm.
A 1.625" (41.25mm) March 110 pulley would result in 2000 @ 650 rpm and 22000 @ 7000 rpm.
DLF is correct and I've been told by alternator shops you shouldn't spin an alternator in excess of 20000 rpms. :shifty:
