Re-arranged my throttle bodies.......
#51
thanks for responding,
see i thought it was the blowers that were trying to slow the engine due to air pressure build up inside the manifold. i can't watch damn videos at work (streetfire.net only). when i got home i got to watch the vids and could see the belt doing its thing.

From the vid it appears that the belt is pretty stable now when the throttles slam shut. It is just the stretch that I am concerned about.
Will the belt stretch more under boost, when each blower requires 100hp of drive power? How much stretch can the belt tolerate? Then again, looking at some papers on belt dynamics, it looks like slip will likely occur in this system and limit stretch anyway. What happens when you go to a wider belt?
Didn't know that they used these OAD pulleys on the Vettes:

maybe this has been mentioned, but what if you off set the blowers (or the pulleys). get a custom crank pulley made and have each blower have its own belt. that way there is less stress on just the one belt. hell then if you wanted you could cog the blowers and keep the accessories on the normal belt. i don't know how much room you have in front of the engine/crank pulley though.

I reclocked the tensioner slightly today so that at the stop there is just a hair between the 2 belt sections. Engine off the tensioner is wound up 3/4 of the way to the other stop. If that isn't enough, then the whole setup has to be changed anyway. I was already surprised to get over 20 psi out of an 8 rib. Will find out how it works out when I get my hood back.
