I have'nt personally faced, but in roughly 2002 or 03 , Baroda cricket assoc at the IPCL ground got a pace measuring device
Since i had 'connections'

me and my bro got access tp the ground where the Baroda Ranji players were practising for their ranji match vs TamilNaat. I saw Munaf Patel being clocked at 146kmh , this was in practice sessions and give or take 3kmph as the persons operating the device was still earning how to use it, might not be accurate. but yes - munna bhai was blinding quick in those days and the ball was thudding into the keeper gloves. I remember all players of both teams stopped what they were doing, just to watch Munna glide in and bowl.
I am sure from about 2004 till about 2006/7 Munna was easily 145+ish and then injuries took their tool...and he became a stock standard 130-135kmph guy.
