Redhawk ....Time to lay this fairytale aside...... Donating Members 2,657 Member For: 21y 11m 17d Gender: Male Location: In the Ferry on the River Styx, not getting out just yet! Posted 25/02/12 01:39 PM Share Posted 25/02/12 01:39 PM Any of you guys owning a FG have any comments on the smaller pulley for the superchargers once you have had them installed and are they worth putting on?Thinking of getting one for the Mystic when I get it tuned.Also, what is the ideal air/fuel ratio for these drive trains as Ford have de-tuned these beasts to buggery.

Just a smaller blower pulley like KPM or the smaller blower pulley and engine overdrive pulley like Herrods are using? I'm trying to understand what is the max rpm the blower should be operated at efficiently.Benny. Edited 26/02/12 10:21 AM by Benny 1 Link to comment Share on other sites More sharing options...

I've recently seen a S/C GS engine killed at 4.5k's by a melted cat. This would be even more of an issue if you start turning the blower harder.

The worst bit is it ran 11.5.....Manual. In the pics it looked like they changed two pulleys. Link to comment Share on other sites More sharing options...
