Yeah there's plenty to be gained but you will have to make some precautions running that much boost. A looped fuel rail is probably appropriate but at the very least 550 injectors and PLENTY of cooling (more than just a HE). Denroll and a few other members here are running 2 pulleys and I'm sure will give their advice soon enough. I was running a smaller sc pulley when I purchased my 180mm but decided to go back to stock on the sc till I was happy with everything else.

You will need to keep her cooler than the HE will allow. I'm sure everyone will say the same - split the cooling and throw a tank in the trunk (or under the bonnet). Going the meth route is another option. Personally I'd be looking at headers first which again will keep her a little cooler at the block.

More knowledgeable members than I will give you better advice but in the meantime just search for split cooling and have a look at the products available from suppliers like Eurocharged and BIP.

I run an 84 and a 180. The BWK had a better affect than the 84 on top of the 180.
Split cooling is when you separate the supercharger intercooler system from the regular coolant system, in stock configuration they utilize the same bleeding point and some feel the heat transfer in the reservoir is bad.

I also have run the 185mm lower/ smaller upper a lot. Ratio or blower speed wise, it is equal to about a 205mm lower but the lighter upper will free up more power than just having a big heavy pulley turning.
The mm numbers sound big but % increase is no that big a difference in the upper MM numbers , than say a 190mm or 195mm.. For example, a 180mm lower is about 14% more ratio speed than stock and a 205mm lower is around 22% more ratio speed. A lot of the GM blower cars are increasing blower speeds up to 35%. blower bearings will exceed ratings but most live by exceeding max bearing speeds for short burst.

I think in a stock system, the benefits do not outweigh the negatives when splitting cooling. If you're running a bigger heat exchanger, a big tank, killer chiller, or any combination of the above then the delta between the intercooling and coolant systems may be enough to warrant the split.

I run a Kleeman 168 crank and the 84 upper.. I also have the larger HE and split the cooling, no heat problems at all.. I also have headers which Really helps with the heat, (highly recommend) if your going to add alot of boost.. Just my 02... Good luck..

This would depend on the rest of your setup. I suspect a very open intake and very restrictive exhaust on the combo may hit the map sensor ceiling. Running an 82mm, a good intake system, BWK, and stock exhaust manifolds may creep the boost up for example.

Hoping this reduces the restriction and gives me some consistent power. The quest for 10s has been a long $$$$ one

I'm about to pull the trigger on a 180 crank pulley to complement the 84mm scp, I want more boost than 12-13psi which is what I'm seeing now at WOT. I'm also switching to a BIP tune, hopefully Tony can make this combo rip.
