Thanx for my admittance.Is anyone running one of these without a turbo?If so any gains?

No gain for N/A, only decent option is ITBs from RHD

i wonder how come most people with boost dont run those intake manifolds. mainly see videos from europe running that type of intake manifold.

The stock manifold has proven efficient even at ~900whp. With some decent headwork and the runners perfectly specified to the head flow characteristics, I could see some decent gain from this type of plenum, but other than that, it’s more of a cosmetic improvement, IMO. With that being said, if you do choose to run this as a aesthetic enhancement, it doesn’t seem to “ruin” efficiency in turbo applications, at least.

That manifold is garbage. Don't waste your money.

Gains you say?

[digger]

runners too short and i bet the alignment and transition to the head will be terrible

These things are popping up for every application. The Chinese are very good st looking at s picture and producing. I doubt there is any engineering behind it.

I was looking at on for an n54. I would not use it as is, but they have done all the light work. Cut it up, clean the welds inside, port match to the head, add bell mouths; a decent starting point.

As others have previously posted, that manifold is worth about eight cents.


The stock manifold is efficient--and in my opinion, a work of art.

God, that is dis-tur-bing.....
