Re: Hotcam Cam Card

i believe the ICL of the hotcam is 109, making it 3 degrees advanced but that's based on my own calculations and information which are highly subject to error

i hope that someone will correct me if i'm wrong.

Re: Hotcam Cam Card

thanks. I searched but cannot seem to find the specific valve opening and closing degrees or the ICL making just guess work with the advertised and @.50 durations. Any one know for sure? Seems like someone ought to for as many people that use this cam.

Re: Hotcam Cam Card

i know it's a 218/228 @ .050 and i have these valve timing events that i found somewhere, but i have no idea where, but they come out to a 272/281 advertised. i don't know how correct these may be but it seems to be in order, for the most part.
