Any issues? What kind of power are you making? IAT's? Already have the 77mm SC pulley and am considering a 168 CP in the near future.

Well you will need supporting mods. I think it pretty close to running a 192.5 mm crank pulley. Headers injectors TB and atleast a trunk tank or killer chiller.

I was just talking to my buddy about this combo today 168/77 he thinks it's too much it should make right around 17psi. Would love to hear from someone who is running this combo, as I my self am planing on going this route if it's not too much. I figure the combo should be close to a 195mm CP which I had on my previous E55 and biggest issue was keeping heat in check.

I don't know why the guys are saying that a 195 is the limit.. I know a couple 55's out here running 210 and 205 crank pulleys. Not sure of the supporting mods but i guess they got them all...

I don't think it's the limit, I think ppl are afraid of blowing their engine and pushing anything over 17psi will put you in limp mode. When I ran the 195 I had KC, engine bay tank, methanol and a little 50 shot and heat was never an issue unless it was stop n go traffic.

Honestly I would talk to Shardul and Exotic Metal about it. As much as I like to think I know, they know a hell of a lot more

installed my 172mm pulley with 650cc injectors at the same time.
Moved from 379kw 780nm to 407kw with the nm not being available due to issue on the dyno.
Car pulls very strong with the traction control fighting even harder than before.
The hiccup in first gear is allot more now which is irritating especially when someone else who does not know the car drives it

When do you drive your car. Is it a daily? Your going to go into limp mode with that combo. It's another lb of boost of a 195. Problem is you well into the yellow level boost and supercharger rpm wise. It's a risk for sure without killer chiller or meth it will be a big power loss. I would stick with a 168 max. If you don't have a really good tuner and dyno tune it I wouldn't even think about it. You need upgraded tb and injectors also

I run a 77mm and custom 160 mm crank pulley at the moment for daily driving and with a 3000 stall. 77/160 is equal to a 185mm crank pulley ish and is a nice aggressive street /daily driver set up.
I have run 185mm and 84mm upper and 190mm with 84mm, 195/84mm upper and 210mm just crank pulley. These combos , I ran 725cc plus injectors, duel inline bosch fuel pumps, ported heads, huge headers, forged pistons and great cooling mods.

I am torn between deciding as well, I currently have the 83mm pulley, and don't know if i should go to a 172 or 180 crank or 77mm clutched pulley and leave the crank alone, or just go FSP
Decisions decisions....

180mm crank and stock SC
Heat is pretty bad, I could barely do one pull to about 70mph before the supercharger kicks out at 180F
A PLM cooler has helped that, easy install. You already have the equivalent (77mm), I would just leave the car alone unless you're interested in spending a lot of time dicking around with cooling. Past splitting/upgraded heat exchanger your options become: meth injection, big trunk tank, and killer chiller.

-Your crank pulley might need changing anyway, now would be a good time to do it
-You get a larger surface area for the belt to grip=less slip
Crank gives you the following disadvantages:
-Costs a lot
-Tough to find a shop that knows what they're doing
-Seen people needing to pin their crank pulleys
That being said I have an ASP 180mm with a stock blower setup, green belt, and I love it. no need for a belt wrap kit adding unnecessary tension just to get a grip going.
