Squid,the moly ring talk you mention is most likely in reference to the nitrous guys.

Anything over say 175 to 200 hp shot and it's not @ all uncommon for them to find it'll knock the moly coating off the face of the ring,and then you tend to lose ring seal,and oil + nitrous = very bad things.

Boost & nitrous do indeed share some traits,but from my understanding that is'nt one of them,nitrous applications often have a very high/quick initial "shock" to the engine in terms of cylinder pressure,and that can be hard on things like moly rings & headgaskets and such,where-as boost tends to be applied in a more "linear" fashion.

Though like a nitrous engine,I'd probably still shy away from low tension oil rings for an application like this.

One other thing I'd mention here is this,if you plan to use the Cometic headgaskets,be sure the machinist understands and can supply a proper RA finish to the decks & heads for those gaskets,as they have some specific recommendations for those MLS gaskets.

Good luck with this!
