The conversation had already turned to “what is high rpm” when I joined in and I only posted information on my combo in response to your questions. I didn’t post pictures in response to 512’s request for “proof” as I didn’t want to derail further. I’m a b-body guy, nobody wants to see that here. Trying to control what’s posted is like trying to control a conversation with your racing buddies. Regardless, my apologies to the OP. Have a Mod delete all the irrelevant posts to clean this thread up.
