Theres about 10 threads about this
I can't remember who it was but it was a pro stock puller on a single turbo made ~2100hp with a t6 steed. This getting out of hand along with the ad and fass crap.
Huh?
Somebody send me one of each free and I'll test on my stock 03. I just need to find a dyno!
meaning pick what "you" want based off your preferences, when its said and done you will never notice the difference between two said manifolds in a seat of the pants comparison. if you dont like the stainless blueing then go to the steed unit. they are both comparable as they are both better than the factory piece.
Fass vs ad (air dog) is the same way, at the end of the day both will get the job done. all you will recieve from asking said questions is general cheerleading that will end up in a brand war thread that gets shut down.
my $.02
The holes are kind of tight on the Stainless to allow for expansion.
ASo do you heat up the manifold and install on a cold engine to prevent cross threading?
I don't recall seeing any results on them going head to head.
Pun intended? Lol
