Cool good idea buuut isnt that the same as closing the VDI ? I forgot the routing of those cluster of runners but I think if the VDI is closed than the primairies are the only ones open anyways right ? Wait im confused. The primaries open with the VDI ??? but why would they call them primaries ?

 

The VDI is completely seperate. The VDI changes the effective runner length on both the primary and secondary runners. The auxillary port system has nothign to do with the VDI system.

Blocking off the secondary runners will not affect the VDI for the primary runners.

 

Hey VON- after i got my engine started it idled so high. It was up to 4K. I checked alot of stuff before i got to lower the idle to 1K. Check your throttle cable, adjust BACV, check for vac, and i think tightening the intake manifold bolts also helps. When we checked the compression it was only at 90psi on each turn. It was low but some said that it will build up after break in..god i cant wait.
