Still learning the STR. Is the Lincoln LS LSD and is the pumpkin the same part? If so I might have to hit up some salvage yards and look for one I'd be willing to try it.

Spoke to Stiegemeier this morning. My kit is on the way back home. Hope to install
this coming Saturday. Will take and post photos. Stiege recommended running
NGK model BKR7E plugs, stock no. 6097 (Rock Auto - $1.76ea. in a pkg. of 10) gapped
at .032"-.035" for use with Snake Bite modification to your STR supercharger.

I have had many Jaguar superchargers upgraded by Bob over the years & never had a problem with one. In addition to superchargers he has also done porting on Jaguar cylinder heads for me. I am sending him a supergharger for a 2007 XKR next week to have the Snakebite done. I would highly recomend Bob to anyone, he has been doing Eaton blowers for years.

I pondered the coil covers for a few minutes initially also...then stuck a LARGE flat head screw driver under the cover from the top and gently pried inward (pushing the handle towards the block) and it pops off. Don't pull outward, you'll break the cover. There are two connection points, each about 1/3 the way into the cover.

@ttwotees
There seems to be some consensus that for high heat/high boost setups a copper plug is safer to use, as it seems they fire better in these conditions than Iridium’s. Another thought (not confirmed) I had was that the very small tip of the iridium’s could become a hotspot and thus a source of pre-ignition (again only in high heat combustion/high boost). As I am running mild boost with the KB, and haven't noticed any of the issues I just haven't experimented with this, so also continue with th e Iridums. However a copper plug may be a good idea for eaton high temp/boost conditions (just have to replace them more often).
Here is the recommendation from KB:

It is the dynamic compression ratio that counts, as the actual compression depends on the time that the camshaft closes (which is usually after the piston is already in a compression cycle) and the amount of boost you apply.
As example here a link to a DCR calculator:
http://www.rbracing-rsr.com/comprAdvHD.htm
Next to that the heat is much higher with a faster spinning eaton. When I take the eaton website as example, the discharge air of the SC is about 300F above ambient, not sure how much the intercooler can cool this down, but it would still be much higher then the NA engine.

No this will not work. If you are interested the Lincoln LS forums can answer the question in detail. The early 2000-2002 LS can have the center section swapped out for a LSD but when the Lincoln LS was upgraded in 2003-2006 the rear end was changed also. We "think" much like the S Type was. So the LS guys with a 2003-2006 either can swap the early rear end assembly in or use a Lincoln Mark VIII center section with custom mounts,drive shafts etc. No one has tried that with the S Type yet. The LS rear end was changed because of vibration and gear whine complaints.
Further problems-if changing the rear end ratio in the LS then no problem but the S Type will be put into limp home mode with a rear gear ratio change. No programmer yet for the S Type to over come this.

It's not quite terrible news for a X308 owner wandering into this section though

Time to hit the Lincoln fora.
