Background:
In a previous post, I discussed the progress of an intake design I have been working on. It was mentioned that the Beta-6 design used components that could be rotated.
This is useful for estimating how to fit larger-diameter piping around the parts inside the Mk7’s engine compartment, but it is undesirable for a finished product to consist of several pieces that need to be joined together.
This has led me to work on a single-piece intake pipe with curvature in multiple planes, which will be discussed in this post.
Progress:
One primary objective for this intake is to have a large cross-sectional area, attempting to take advantage of the space inside the engine compartment.
To do this, the pipe must simultaneously curve in more than one direction, which the prior one-piece designs did not do.
Using the measurements from the Beta-6 design, I set about creating a one-piece part drawing.
Having airflow changing direction is undesirable, but the hope is that the larger diameter will reduce friction-caused pressure losses sufficiently to overcome the pressure losses caused by the change in direction.
This outcome seems likely based on the rotation test done with the Beta-6 intake.
Testing the newest design on the flow bench will eventually answer that question, but for now, I have been giving extra attention to analyzing the part’s areas of curvature.
Unsurprisingly, the inside corner before the transition to the Turbo Inlet Elbow deserves some attention.
The rest of the intake looks good, with the goal of smooth bends.
Another part that I am beginning work on is a turbo inlet elbow to connect with the intake.
The two pieces together will look something like what is shown below:
Hi Jeff,
Will the PCV valve connection be added to the turbo inlet later?
Yes, I have it as part of the design. I didn’t show it in the post since I am still working on the internal passage from the port to the location on the elbow that I want to draw vacuum from.
Hey,Jeff you should sell this I’ll buy it
A couple vendors have offered to help bring it to the market, I’ll see. I’m happy to make it available once I’m done, how that will happen I’m unsure of.
Jeff, Amazing work really turning into beautiful design – I will be waiting with cash in hand for this. Love your site and have given me countless hours of learning thank you!
Thank you!
Jeff, do you believe this will cause issues to a stock pvc system anything that can be done with upgrading TIP to avoid that you know of? I know data driven discussed how bad it was with the Burger Motorsports TIP. thanks for any insight!
The inlet elbow is something I am paying attention to in order to try and improve on the generally poor vacuum generation of the available TIPs. It presents an interesting challenge because while greater vacuum inside the elbow may be good for the crankcase, it is not helpful to the compressor.
