The inside of the airbox really kicked my butt, finally I recalibrated and it got a little better and I was able to complete the scan…64267 frames
The problem is tracking, IDK if it’s something I’m doing wrong or what, but the scanner is really struggling with tracking. While I understand it saying need more markers, when it loses tracking it keeps scanning and that totally blows the scan…start over.
Got the job done.

Started at 6am and finished at 4pm, whew, lot of scanning. Now to Reverse Engineer it all. May even mix in some CFD.
Making a new high-flow airbox and modified velocity stacks.
That is a little overboard with the frames count on that small object .
No wonder your spent all your RAM to get it fused , I guess 80% of the frames was simply removed in the fusing process .
Regarding the tracking , the small markers may be to blame especially when you moving the scanner on a specific angle , I stopped using it for the same reason .
But most important you did it well at the end !
How do you reduce the frame count? I’m just scanning the object, and that’s where it comes out once all the nooks and crannies are done.
I did find that by reducing the scanning distance window from default of 200/400 to 220/350 I got rid of a lot of the trash in the scan. Yea, it reduced the distances it could scan, but my theory was that things were out of focus/quality anyway at the lower/higher distances so I just limited the scanner to not scan at those ranges. Is this dumb?
I recommend you buy yourself a black silicone mat for the desktop table to avoid scanning the bottom on the table as it can interfere with the tracking if your turntable is moving , plus you get less junk frames.
It is difficult to not get as much additional stuff when you scanning a black object on a black turntable , hard to avoid .
I usually never get above 20.000 frames , then if needed scanning different angles at 20.000 as well .
I understand you had a very complex object and you did great job with it .
Lucky you don’t got any shifting in frames .
With so little frame size it is hard to not over scan the surfaces many times .
I would definitely spray it , use laser brightness to max 7 to avoid catching up the black turntable , set it up slightly higher on the turntable as well to catch better the edges but that is my personal workflow .
No matter how you doing as long you get good results 
Keep up the good work Robin !
