sorry that took so long....
here are the long waited install pics and dyno graph
gain from this intake manifold is about 10 hp
it increases 15~20% more air flow
numbers are: 274 HP, 266 TQ, 19 psi (mustang dyno)

i have done lots research....
i think the stock intake manifold puts huge restriction on flow
the direct flow design will free up all the restriction
this custom one is made from sheet metal
it cuts down weight dramatically
the runner isn't tapered...they all been ported
it will also run a bigger size throttle body (dual throttle isn't helpful for my setup)
anyway....will post the result after dyno
