Good idea, I got my hands on a Draggy and will do a run on Wednesday.

I got a few photos of some of the new parts for my engine and could get photos of anything engine related. This is an opportunity that will quickly be lost as the motor is finally coming together so ask me now if you want.
I will post the photos on my engine build thread.

Some photos of the AEM340 swap. Don't do like me and buy the right part that I listed. I did not and had to break off the tabs. It's perfectly fine though.

Dick H made a another revision to the MAF sensor housing he made me. This one more closely matches design of the OEM so that it requires less MAF scaling via tuning. Also he added a metal air straightener and some carbon fiber bolstering. He's a complete legend of fabrication, and Loi is a complete legend in tuning making multiple revisions to tunes to my many many gradual mods.

Looking forward to seeing if tuning is necessary for you, it should be close to not needed. To clarify, the material is 20% carbon fiber, the pattern you see is just a visual artifact from the surface I used and nothing more. The straightener is a bonus item, I'm not able to verify a difference with or without it on my end.

Thank you for clarifying. That makes sense — I misunderstood the surface pattern and thought there was additional carbon fiber bolstering, but it being 20% carbon fiber material is even cleaner.

I really appreciate you making this revision. The fact that it more closely follows the OEM MAF housing design and should require less MAF scaling is exactly what I was hoping for. I’m very grateful for all the work you’ve put into this.

Also, just for reference, Loi said the air straightener 100% makes a difference. He was very clear that the honeycomb/straightener helps give the MAF sensor a cleaner, more direct airflow path. So even if it was a bonus item, I’m very happy it’s included.

I’m still waiting for Loi to respond about this latest revision, but I’ll definitely share what he says once I hear back.

Between your fabrication/design work and Loi’s tuning work, I feel very fortunate. You’ve both been complete legends through all my many gradual revisions and experiments.

The Straightener also slows the air flow evenly that the MAP can get, and adjust to more accurate reads.

I am here working my butt off arranging security for a big festival running on 7 hours of sleep total in the past 4 days and i see this.
I am not going to lie, I got physically aroused.

I will be pursuing this route most definitely.

I think the CAD for the FSE is wrong because you couldn't possibly mount the base then the top part based on that picture but their 2GR-FE and 2GR-FKS CAD pics are correct. The top plenum fasteners on the 2GR-FSE should be recessed, nothing a bit oif CAD editing can't solve. Price seem reasonable but short plenum for daily driving is a total waste. Would be great for turbocharging though.

I am hoping DickH will also put his input.
His designs are with very long runners designed to make power in the midrange where you want it.
His runners are like 12 times or so as long.
I see the runner now you are right, they are meant for a turbo.

I am working a lot these days, but once I get back I will definitely contact them about this intake manifold.
It looks like the runner length could be adjustable.
