Although it does suggest that moving the IAT sensor may not actually help you get anymore headroom . If IAT is used to calculate reported calc. load that goes against you , but the reverse when max. calc. load is calculated . So one will offset the other.

I am pretty excited with the progress we have made. I am bummed that the weather has turned here. Was in the 30's this morning. The car will be on jack stands before the end of the month for the winter while I execute my growing list of things to address, so no more tuning for a while, but should be able to post about other stuff between now and spring...
Thank you FazdaRX_8 and Brettus, you have both been a great help! For sure not the end of the road tho

This thread has helped me join the dots on the subject of calculated load . I decided to start a new thread explaining it over here ..... https://www.rx8club.com/series-i-engine-tuning-forum-63/maximum-calculated-load-what-does-how-override-248857/

I also need to redo some heat shielding and hoses. The OMP fared well. I was a little concerned about it at first. It stopped consuming oil for a bit, but that turned out to be because I had vented the OMP breather instead of plumbing it back into the intake pre-compressor. It's been consuming oil like normal ever since plumbing it back in, which also got rid of a pesky lean area I was seeing right on cusp of OL/CL. Yeah, I figured out that the OMP breather line needs metered air!

I was actually hoping for advice on the cooling issue but open to all advice.
I don't disagree with you. But as far as motor mods go my plan at this point is to acquire a second motor to build up while I continue to push this current motor as far as it will go. There will be some lessons learned, I am sure!

Ya, I was wondering how close I would get. I didn't do any WOT logging thru the RPM range, just some short bursts in 2'nd gear. Hit 233% load in one log and 221% in another. Fueling and timing was as expected for my tune. I think the 221% load would have gone higher, but the wheels broke loose. I loaded it up in VD just because it is easy to look at it as a graph (yeah, I know I could do it in excel) and you can see how the engine RPM took off
The highest MAF voltage I hit was 4.79. But I could definitely see hitting 5V or more if I let it sweep through the range and build boost. I was too focused on calc load and afr to look at the boost gauge, so not sure what it peaked at. But it was definitely a huge difference

And this tune has the stock MAF scale with stock intake diameter, so this ain't no inflation... Heh... Ya it kinda scared me. I'm not so sure I will log a full WOT run yet...

Heh, besides all the other stuff I need to sort out, the weather up here is getting colder. We had hail this afternoon that stuck to the ground like snow... I am probably toying with danger as it is. But seriously thinking about it for next year...

Nice!!
You know I have a log where my Maf reading went to 6v at 550gs I think the Maf can go higher then 5 volts.
It was a instance where my Maf got wet on a really wet day.

this is pretty promising. good job slash
can't wait for next year to get here....4in maf plus 15# mmmm. going to consider meth? I feel like at that psi you're playing with fire on 93. only way to find out it trial and error though. good luck
