Yeah that would be awesome. I will try to do a little more research and adn thinking too. I mean all I need is to open and close 4 lids at specific times. reverse engineering that in excel. Even if its not dead nuts with the timing of the cams, it will be farther in the ball park than it is now.

All very good points. I remember seeing and talking a little with boostinbenjan. I looked as his ideas actually when I was doing the research.

as for the center inlet style. I did this one for Aaron a few days ago.

I will mess with that too and turn the TB straight on to see what it does. he has it cocked for the IC setup he id running.
