FastReligion Carbon Fiber Short Ram Intake (V2 MR16DDT)
PREORDER. Ends 3-19-21.
Coming in at only 1 lb 13oz, this is a serious piece of hardware.
Made from carbon fiber and 6061 aluminum, this intake is both the lightest and most durable on the market.
With over 500 test miles on the prototype, both highway and city, we have put this through the ringer to make sure it is the best design possible.
Our design philosophy is efficiency. We put that into designing this system:
The biggest gripe we have had with the intakes we have used in the past is: it seemed like the goal was a BIG pipe before and after the MAF which creates several issues:
As the air leaves the large pipe and is forced down into the MAF tube, air velocity increases and also causes turbulence, as the transition is very sharp and harsh.
Then when the air leaves the MAF tube, it expands VERY quickly which reduces the velocity and creates turbulence. In this transition the vacuum pulling the air in can actually create a dead zone after the expansion. Think of trash in the bed of a pickup truck. It gets stuck in the vortex created by the change in shape from the cab to the bed. This greatly reduces the efficiency of the vacuum and air flow.
Then when the pipe reduces back down to go into the turbo inlet pipe, the air gains back velocity, but not as much due to the turbulent air shape and the increased drag on the air created by the previous transition.
You may get a beefy big pipe that looks cool in the engine bay, but the internal flow structure is ALL over the place.
Our design maintains close to the same ID from start to finish (there is less than a 1mm change in size as the air flows into the MAF tube). Meaning the air does not have to change shape as it flows. So the vacuum pulling it in is consistent all the way. We also used a smooth transition to the turbo inlet pipe. A ~6" long smooth reduction in size means the vacuum pressure along the tube increases incrementally so the acceleration of the air into the smaller pipe is smooth and linear. All of this is done to make the turbo use energy to create boost, and not pull in air. Efficiency.
