Will an Intake like these ones work?

I was looking at couple of race cars with IS-F engines and I noticed that they run a straight short ram intake or some kind of intake scoop. I think an intake like that should have superior airflow than the stock setup and there should not be as much heat soak as stock. As long as the diameter of the straight pipe is the same as the stock pipe where the MAF sensor is located it should not mess with the MAF scaling. I just wondering if the ECU will compensate for the increase in airflow.

Any thoughts?

Based on the tests of other aftermarket intakes, there is little to no benefit to changing the stock design. You get much better results by opening up the exhaust side (headers/catback).

Not sure how the ECU would compensate with the change of intake.

I understand that but non of the tested intake get flow like the ones on the pictures; all of the has a similar path to the stock intake with a 90° bend. I imagine those race teams know what they are doing; I don't think they will be adding a component that makes they race car slower.....

look at the tests and results that have been proven. there is no lack of flow with the oem intake. also those race team can tune the motor as they are not setup like the oem setup. apples to oranges!

Bet they wrap the manifolds, and do other things to prevent heat soak.

You will also find they have aftermarket ECU's to compensate the extra airflow from the shorter intake.

I honestly don't think it's worth it for the minimal gains.

Not unless they find a way to crack our ECU's for mapping.

This is the key - unless you can tune the ECU any mod to the intake will probably be a waste.

So the AFE pro filter is a waste also.... right?

I have AFE filter, a Carson intake tube and the intake scoops! I am a sucker.

Generally speaking, there will probably be no measurable difference driving around or at the track.

So does anyone knows who makes the aftermarket ECU's that those race teams are running?

So it seems that one of those cars is running a Motec M880




Its weird because it says on the motec website that supports up to 12 injectors; so they must be doing something weird. 6k for the ECU
