5.4 / 5.8 Cast or Sheet metal manifold Test

[5.8MysticCobra]

I'm building a 5.8 sleeved fully built motor and been looking for the best Intake manifold out there . I'm amazed nobody has done a review on all intakes avaliable for TT 5.4/5.8 . I will list what i see avaliable for 1200+ hp applications

Expensive to Cheapiest

$5500.00-Berry Motorsports Billet upper "Which I have seen tested on a 5.4 TT and was down on power compared to the Hogans sheet metal "
$3500.00- Hogans Sheet metal , Same intake John @ Accufab uses which is the ugliest but seems to do the job for his 2500+ 4.6
$2999.00-MMR Sheet Metal ,same one used on the GT500 drag car
$1499.00-MMR Hrbrid intake , can be used on the 5.4 with manifold adapters MMR sells
$1600.00-4.6 DOHC FR500C Cast intake .Can be used with adapters as well
$650.00-5.0 Boss302 /Cobra Jet W/MMR adapters

Appreciate any input on these manifolds on TT applications .I'm intrested to see power differences comparing each manifold on the same TT 5.4/5.8 combo with about 30-40lbs of boost shooting for the most efficent way to make 1500hp. I'm almost certain no one has compared these manifolds .I will post pics of each manifold to compare but I'm sure you guys know which ones they are

Why has this thread gone no where. Would be so useful.
