Default Too light a Pulley?

OK, I think I searched enough...

My question is, I pulled the A/C out of the car and was wondering if a pulley made for JUST the Alt./PS exists.
A quick blurb in Vishnu's sight said "light- but not too light"
So can it be too light? I was kicking around the idea of machining the A/C chunk out of the pulley...any opinions?
Planning on kicking the wee out of this engine 'til it goes, then put in an engine with enough power that random ideas like this are not neccesary.

Back to the drawing board?

you could just take A/C out.... loose close to 30Lbs from that.

then get a Mr.josh and machine that down so it is a single belt pulley.

Actually I've heard you can throw some wierd ce lights with too light of a pully and or a 9lb fw. Appearantly the crank accelerates too fast. Yes I find it odd, but it's been mentioned. I don't have the details, you might try to search on lightened flywheel, that what I was doing when it happened.

My pulley never caused me any problems, and now its coupled with a 9lb flywheel and a lightned/balanced/knifegded crank and I have no problems to speak of. The car revs very very fast and you do get a bit of vibration in the clutch with a very light flywheel since it not able to dampen vibrations as much as a stock flywheel of a 14 lb flywheel (which I had with no vibrations with).

Thanks for the advice everybody!
Most of this just kind of came up fooling around with ideas...
(Guess that's how anything goes)

I KNOW for sure that my little sub-2 litre will not make any real firepower, but it's fun to try struff on an engine you don't care TOO much about...

If something spectacular happens, I'll be sure to tell ya'.
