[DeTomaso] Something other than tires - Twin Turbo Pantera on Ebay

[Mike Drew]

Sounds like a normally aspirated aluminum head roller cam 408 stroker just waiting to happen! :)

> The carb sits atop a horizontally split plenum with a pressure flap on the split partition.   The upper part of the plenum releases the fuel air mix from under the carb and sends it to the  input side of the turbos.  After going through the pressurization in the turbo it is returned to the underside of the slit on the plenum where it enters the intake manifold.   When the turbo pressure is great enough to overide the natural suction under the carb the flap on the horizontal plenum closes allowing the turbos to make pressure above atmosphere.  When the turbos are not engaged the intake mixture goes through the flap area effectively by passing the turbos.  I do have one of the setups that I am replacing with a hat unit.  The intake seems to work pretty well except for when it backfires.  Best case the explosion blows the plenum flap shut slowing the intake burn.
