There are a few 185's but my first time hearin about any 190's. 
Definitely hit up shardul. He is a huge asset to the community and he knows what he's talkin about.

A bunch of us run 185`s.. I know of at least 5-6 195`s out there and several 190`s like Shardul.. I may go to a 200mm this fall..

If the search button serves me correctly, 200 MM would be adding 46MM's from a stock (154MM) pulley which would than create .2 PSI of boost per MM then equaling an extra 9.2 PSI of boost. and at about 14HP per 1 extra PSI of boost, thats almost 129HP from a stock to 200MM pulley? seems too easy... that is, when you get cooling taken care of. Am i understanding this correctly?

What's with everyone wanting a wagon wheel for a pulley? I would think that would just turn your supercharger into a heat pump. How much timing would you have to pull out with a 190mm? I would also think bearings would start failing real fast.
I'm more for working with the boost level I have. With that said... Finding a way to cool the boost down that you already have, will probably give you better results.

Anything over 180 is a waste if you can't keep the temps down.what is the point of going from a 180 to a 195 when that extra 1.5lbs of boost just cost you an extra 30 degree hike in intake temps.
I think someone is also running a 210mm in the middle east also.

Well a 195 or 200 mm will make a crapload more torque down low. Yes there will be a trade off without cooling, but for day to day, non track driving a larger pulley gives you a bigger kick in the pants.

Peak IAT 85 degree's.
runs 18-19 degree's at wot
I had two adjustments to the tune and was out of fuel so I feel there is ALOT left in it.
ya I guess it makes ok TQ....

210mm in UAE but using NOS to cool the car and it has every mod. even a 155 S/C. it is strong. Gearbox can't handle it. every couple of months changing he clutchs. they are wearing.
but the car is unbleivable fast.
i wish there is a way to increase the volume of air wthout this method. why no one made bigger S/C for this car.

How the heck are you guys putting the power to the ground?I have no traction with my 275/35 nitto invos and only have about 570rwt.
Im hitting the dyno today so maybe I picked up some from the retune.
