ACT plenum twin throttle body
Discussion

I run a 4.5/4.6L with a triple plenum, it is over the top for a 4.5L so a double would suit it better I'm told using half throttle is enough.

The above is with the triple and coil packs etc I had 330BHP with out the triple and running on a Mark Adams chip so not much of a gain for the out lay

Did you have the larger 72mm or standard 4.5 plenum fitted prior to the fitting of the triple ?![](http://thumbsnap.com/sc/Iev4FydY.png)
