@@motoiq well then you're well aware of cryogenic treatments and martensitic start and finish temps but - where do you get the info on what alloys are used in these engines to even .. explain to me why you would cryo a tempered steel (nitrided?) crankshaft without a salt or lead bath austemper? Is that 5% of martensite going to matter on these alloys or is that literally just marketing? I don't know if I have to say this or not but I obviously respect the hell out of ya man we obviously both have similar interests and whatnot - I'm not.. necessarily well okay I know it sounds like it over text but I really am not like arguing or trying to. Honestly I enjoy your videos but I couldn't get past the "we cryo our cranks" just because to me personally? With my knowledge which is not absolute (I'm sure we both forget stuff although everything I heard you say was correct but I did not finish the video because of the cryo deal). Moto, I owe you an apology for not finishing the video because, well obviously being a doctor on the internet puts me in a unique position henceforth my name. I just fail to understand the purpose behind cryo treatment post heat treatment, unless it's mainly a marketing deal. We don't know each other, but I absolutely cannot stand "marketing" or "advertising" or "corporate America" to an extent that you would not believe, so seeing someone that I respect start saying oh ya well soak your metal in ln2 for 500$ when I.. work in said corporate America and as a hobby I make high carbide PM kitchen knives for professional chefs, so obviously I know what alloys benefit from cryogenic treatments and which do not. But I have no idea how you are identifying these alloys being used because I personally have xrf/XRD and it's not enough for that purpose. GC-MS-MS? That would not be cheap but I can't rule it out. Also I'm incredibly sorry for freaking saying the school thing. That was a bit out of line. I hate people who go around with where they went to school. But since I did and I kinda know what I know, I am sorry but I did have to ask questions about it. I suppose I still do have questions about it. I don't deal in the engine steels or anything like that nor do I know where to find out what is what. I'm in the austenitic/duplex alloy department for work, henceforth my fun hobby where I get to play with ZTA ceramics and metals. Not that we'd want to cause of asperities grain growth yada yada but - is there a way to find out what alloy is being used so it can be re-heat treated or suchlike? I could say that would make a difference a little bit more than say just chilling to 196c. I work for US steel automotive research as a metallurgist fyi. I thought I posted that.

@@KZread_Scientist Alloys for the pistons, cranks, and rods are known from the manufacturers. 4340 is pretty common for rods and cranks, the crank is not SAE 4340 but the JIS more or less equivalent, I forget the number. The crank is nitrated. The pistons are 2618 which is pretty common for American forged pistons. 4032 used to be popular but with improvements in piston design has fallen out of favor lately. As for the carpenter alloy, it was in the valve manufacturer info, I forgot which carpenter alloy numbers were used but since I was on a one-take roll when shooting the video I just kept going to make post-production easier plus I didn't think our audience would care that much. Cryo is more wear-resistant on an engine's ferrous rubbing surfaces. I have seen this in engines many times. It is also well documented in tool steels. Personally, I don't think it has much value in nonferrous metals except maybe stress relief. Look up some of the white papers on google about cryo. There are many interesting ones. I started using it many years ago and it seems to have worthwhile results in our high-power engines. In one series we do engines for, our engines go about 2x longer in between refreshes compared to our competitors. In our race engines, the rings have very little wear even after a season of use. The gaps stay close to the same and the second compression ring isn't even fully seated across the face! Cryoing eliminated valve spring failure for us, even with aggressive roller cams. One of my rifles went from one MOA accuracy to an astounding 0.25 MOA! It was also less sensitive to ammo quality, shooting no worse than 1.5 MOA even with cheap ammo on a bad day. Good cryotreating isn't so much dipping in LN2 but slowly reducing the temp to LN2 temp, then slowly increasing the temp to close to the tempering point over 72 plus hours so it probably isn't just the cold but also the tempering doing something. It does help though and in some alloys the difference is shocking. I was skeptical at first and cautious in its application but now I use it a lot more. I have a technical question, How do you form and sharpen ZTA into a knife?

I have zero intention to build out my VB WRX with the FA24 to this extent, but really enjoyed the in depth explanation of the engine’s pros and cons. I could listen to you explain how things work for hours. Really appreciate the time, energy and genuine enthusiasm for what you do.

For informative purposes.. I paid 11k for my Rebuilt title 2016 WRX with 65k miles. I threw a bearing at 85k miles drove it until 100k ticking like a mf since I had a motor ready(I was getting -2FKL and -11FBK for a while cruising at under 15% throttle before it started to tick bad. But under WOT or stronger acceleration it would disappear and my AP would read zero sometimes a -2 or -4 on occasion which supposedly was acceptable) it was FBO minus manifold on a TMIC. I spent maybe 5-6kish for the upgrades? Was flex with lpfp/hpfp upgraded. 8K for a new P2P Closed deck Longblock 0 miles (costs 14k got lucky, I was going to buy a shortblock for 6k that same week) has everything done to it minus cams, 625+ rod bolt 1/2" headstuds etc 3k for STI Swap 2k for TR GTX29 turbo 7k for Misc parts & labor 1k for Ecutek software/tune Limited to high mid 400 whp because of no secondary injection :c once I get that which is another 3kish I can do 510-520whp on my GTX29. I'll run what I have until end of year and get my secondary fueling and a BL58XR (Claims 770hp of airflow) biggest you can go stock location before you spend 6k+ on an ETS turbo kit.. or if I get lucky and find another ETS kit for 3k ill snag that. For those wondering, I am indeed broke as fuck and I finish concrete for a living.

@@motoiq Damn buddy. Nobody ever replies to my questions on other channels. Thank you so much for that. I've subscribed since finding you, and your videos are so helpful. I'm building a GR86 for supercharging, and I don't want to miss a supporting mod. Keep up the great work!

Are you guys aware of the fa24 oil pressure drop issues on track days? This is even happening on stock grip setups

Yes, I think this baffle will help as some other things, oddly the 86 cup cars are ok, we had two of those motors so far and the oiling system is stock and the bearings are fine.

The only cheap way to help that issue... oil accumulator... and do everything you can to keep the oil in the pan above the pick-up tube. Run almost a quart of oil over stock, and thicker oil...

Probably the IAG baffle is going to make a huge difference.

@@motoiq This x100. None of the cup guys are having any issues. None. And I know a couple of those guys and I guarantee they are pulling more g's than anyone reporting the issue. Little bird told me maybe the problem is where the "low oil pressure" is being measured. Something about a blind passage at the top of the engine....

Are the BRZ and WRX Engine the same head castings?

No, no one cares about those super old engines.

This is the bob ross of Subarus lol

I couldn't find any IAG parts for the 2023 BRZ. Did you accidentally leak the secret to 900BRZ's stable oil pressure? 🤨

The baffle is new so you might have to call on it.
