There are too many variables and hardly scientific then.

It's rather extensive. Longer then I care to get into. I doubt it's as intensive as your company though.

I disagree. Take car with or without mods. Dyno said car. Add one new manifold. Any variation would be due solely to the manifold. I understand a different car with different mods would generate different results but for the same one car the test seems valid to me. It only becomes a mess if the intake is promised to generate "x" increase in power for all variations.

So what about tuning?

@s2d4, while I agree with what you're getting after, I also disagree. Engines are very dynamic in nature, so testing them in a static condition doesn't make much sense nor does it paint the whole picture. I don't know of a flow bench that could accurately test an intake manifold in a real world condition.

Indeed.
So how were you going to mitigate the engine dynamics, turbo efficiency and tune from skewing the data?

I don't think "skewing" is the appropriate term here. Regardless of any other mods if there is an increase in power from fitting this manifold (with or without a tune*) then there has been an increase in power.

Analogy. Forced induction engine, oem exhaust. Dynoed. Complete exhaust system fitted. Dyno shows increase. Has the forced induction skewed the results? I don't know but if there has been an increase in power then the exhaust system is the cause.

* I think this intake would be poor value without a tune but it maybe that na shows a benefit without a tune. I don't like the chances of realising its potential without a tune if going fi. This is all conjecture on my part.

Tl;dr. If the intake increases power I'm interested.

Skewing could go either way, didn't mean anything bad by it.

so, the tune was done on which intake manifold?

You would dyno the car as is. You would then swap to our manifold and re-tune. After tune is where we would want it, dyno the car for dyno numbers. Also have to make sure conditions are the same, ideally all done the same day.

Fair enough, would the "as is "car tuned by the same person? and would the new intake manifold and subsequent tune be done under the same tuning philosophy?

Well, my company is the Navy so you're probably right about that.

Ahhh thanks for the link. I will be watching both threads

[yo joshman]

In any case im just glad that companies are finally starting to make these type of upgrades available. Im a naturally aspirated guy and this will be a much better option than just cold air intakes that are currently on the market.

Yes, it should be. Less time consuming and easier.
