looks like a chassis dyno, not wheel one which would explain it.

Would it be better(with price not being a variable) to install this, or wait for a third party manufacturer to release an intake manifold(such as FBM)??

In addition, the dyno plot shows no loss in power below 4000rpm and a significant gain everywhere above. I find it hard to believe that the engineers at Toyota/Subaru would have not designed a longer runner manifold to take advantage of this. I will also point out that the torque rise between 5500rpm and 6500rpm is very similar to that of gains found from tuning.

I am not saying that this product does not work, though I would like to see 3rd party tests before I am totally convinced.

I think they figured it out but not for us... fa20dit manifold...

Those look like TGVs, which the turbo Subie engines have always had versus the NA engines. Pretty common to remove them either by gutting the stock ones or finding a replacement (TiC/MAW makes a polymer one so it even kind of acts like a phenolic spacer, transferring less heat from the engine into the manifold).

Id like to point out spacers do work... I had one in my old mustang and dynod it before and after. The results were real, but I find it hard to believe it's good for that much power up top.

What you mean is they CAN work. A single case does not describe the outcome of all spacers...

No brackets in the pics bro. I agree that this was probably developed after looking at the FA20DIT. They probably want to sell them to the new WRX owners as TGV type deletes. Who is going to be the guinea pig to buy them and give us an independant dyno? I mean you get all those pieces for such a low low price.

So with this, is it safe to assume we can break the 210whp for na with a tune and bolt ons

If it truly works as claimed, I'm interested. I'm especially interested to see this + an e85 tune dyno

I'm unconvinced this isn't eating into headroom left on the table that a tune takes advantage of.

I'm unconvinced as well. I'm sure a tune can take advantage of it. It raises the intake manifold doesn't it?

these need to be polymer and half the price. I got it, billet is cool. But not needed in this application IMO. The factory intake isnt even metal.

Car people are like old school gun people - metal good, plastic bad! Even though the thermoplastic resins are actually superior from a performance AND manufacturing standpoint.

15hp no tune? Get a tune and you find 15hp...combing the two won't be additive for 30hp, I guarantee it. If you can make 30hp on pump gas with a just a tune and these things, I'll ask Hachi to ban me.

30hp on NA & pump gas will require catless headers, op/fp & tune. A darn good conservative, itteratively developed tune.

On phone I am. Therefore, if mistakes I make, Frank Oz blame you should.

Nah nah, it requires some billet aluminum spacers and Crawford's OTS tune, bro.
