Lightweight flywheel & Underdrive pulleys together?

I apologise as this May have been brought up before and I have scoured the net for hours (literally) but can't seem to find any definitive answers just a bunch of hear say and theories. I have just had a lightweight flywheel installed and was wondering if it is safe to run a set of lightened underdrive pulleys too? Would it damage my engine or would it be fine? Has anyone had any experience with running both? Thanks.

be fine buddy the pulleys wont affect anything really may give you some extra bhp but will be negligable

It will be fine. I ran an underdrive pulley for a few years without issue. In theory it is best to run both a lightened flywheel and underdrive pulley.
