Gen IV MAF, what is different about it from previous generations?
I recall Ryan doing some dyno analysis on an older version. I’m not going to rehash what’s already been discussed about that as I don’t want to derail the turbo discussion, but curious what the data is for the new version?

MAF is not NLA. Close, but not just yet.
Doh! I just had a customer an hour ago say it took a week and cost $700

Right now, for the turbo, it’s just an aluminum alternative.

I MIGHT have an announcement on Sunday afternoon. Let’s see how the drive home from Flagstaff goes.

@jjdeneen918 from talking to Joey this new version is supposed to be the same size as stock and the MAF sensor is supposed to have the same curve as the old MAF sensor, so it should be a direct replacement for the older MAF's which I support. I think a direct replacement in an all aluminum housing with an easily replaceable sensor makes it a good alternative to the 20 year old MAF housings. I didn't like trying to change the MAF for performance but I do like changing the MAF for robustness and ability to stay current since you can pickup a new sensor just about anywhere for $100-130.
Do the 95-97 MAF's have the intake air sensor in them as well like a lot of the Denso MAF's?

They do, with the aluminum housing and modern sensor you have to switch the pin out on the plug so that you retain intake temp.
Any concerns with the additional heat retained by the aluminum construction moving you further up the IAT comp table curves? I've always preferred using ABS type injection molded housings like the OEM's for MAF's that incorporate the IAT sensor if I'm not able to separate the IAT out and install it where it really ought to be

Always a concern but any and all IATs are overcome by installing a snorkel. Gets you darn near ambient.

I would not be overly concerned considering the temp sensor is now suspended inside the housing isolated by the plastic sensor body. The aluminum housing might retain a little more heat giving higher readings at idle when air flow is quite low but as the air speed picks up the air spends much less time in that 4" section of housing to really transfer enough heat to worry about. If this was a race car and an all out effort was needed, I would certainly isolate and cool the intake air temps as much as possible (which is why you see drag guys dropping 20lbs of ice in an intercooler tank per run) but in this use I think very little change would be evident.
And let's be perfectly honest this is still an 80 series and people are going to want to come up with ways to make things better, so if you wanted to heat shield the housing you certainly could do that.

I was thinking more traffic condition based and slow speed off road desert type heat conditions where the Snorkle really isn't doing all that much given the low airflow speeds yet high engine bay area temps is all.

I hear what you are saying and Joey and I just talked about this, but in those conditions, when you are at idle high intake air temps don't really mean anything. It is the high intake air temps, at high combustion pressures that give you knock. The heated wire element sensors are much quicker to react to temp changes than any of the older temp sensors and that is a big part of why OEMs now only use those stye MAF sensors.
Yea I totally understand I just figured given I'm assuming it's design premise is not only to be available as a matched part to replace a harder to obtain OEM piece but also to be used in a non intercooled turbo setup every aid in construction would perhaps make sense, I think the OEM's moved to the incorporated MAF/IAT as much for packaging constraints and production cost benefit as they did for response reasons lol but that's another subject entirely
To be clear I have no doubt it will work I was merely curious regarding the choice of material

For sure, I think it is a manufacturing question more than anything. 3D printing is still a little slow and some of the plastics don't hold up well to high temps.
In an ideal world we could make the intake out of something that was an excellent thermal insulator, was easy to work with, was durable, etc. but most small shops/individuals do not have that ability.

Isn’t that the exact condition engineers at Mr. T designed the factory snorkel for? I know, I know the most use cases are deep water fording and roll over protection but it was actually designed for the deserts of Middle East.
Also I have been thinking about the aluminum housing and it can be easily addressed with some AC insolation tape around the aluminum housing and don’t forgot to do the whole air box.

It's entirely possible I'm not in position of having Mr. T's design reasoning's.
Agreed there's plenty of products out there to assist with thermal's when it comes to underhood radiant temps and such, as I stated it wasn't me questioning whether or not an aluminum housing would function or not I know it will I probably tune 15 cars a weeks with aluminum MAF housings incorporating IAT I was merely suggesting that a properly designed and constructed ABS/Polymer design might afford benefits.

I will say, maybe. I will also say it’s not my product to make those decisions with. I’ll also say whatever that delta is, it’s minimal and outside the scope of the bigger picture. I also say there are a ton of these already out there without reported negatively affected IATs.
I'm sure there's plenty out there running fine it was merely a suggestion/thought on my end nothing more.
