Good example.
You touched all of the major points and addressed them accordingly by including which mods you would go with, why you would use them, and a cause of failure. There should be more posts like this.
So nothing too extensive. A ported and polished head would be a nice addition I would think. Maybe some forged sleeves for added protection. This is good information.
How about a picture of this blower? Just for reference purposes.

And yeah, a ported head, sleeves, rods, etc... they are all at the discretion of the guy modding, and would definitely help the cause.
As far as a picture, here is one from Lysholm;
There is all kinds of info on their site, under 1600AX

When getting into the high boost situations, it will require some extensive mods to handle the power and pressure.
I would personally go about building the engine, the same way as I'd build for a high power TVS;
- supply the fuel; large enough injectors (like 80's), enough flow from the pump (pump rewire, or replacement), and maybe a good pressure control mechanism (via return style).
- let the air flow; get a good header, DP and catback. Get a reputable intake system.
- cool it down; pressure makes heat. Get a dual pass, and a good heat exchanger... look into methanol injection.
- deal with the pressure; at high boost, the springs will float, and the head will lift. ARP head studs, and higher pressure springs are a must. As well, the plugs will have to be colder, and gaped properly to avoid blow out.
- deal with the power; are the rings going to handle it? How about the pistons? Plan for a potential failure.
- dial it in; get it tuned. You want everything to jive just right. One mistake can mean catastrophic failure when your pushing that much airflow... you don't want to lean out, or knock.... a tune will fix that.
- put the power to the ground; look into proper mounts (rotated), a good clutch, and maybe axles. Power is useless with a blown clutch or a busted axle or transmission.

+ an oil cooler just for recirculating cool oil the the charger, or tap the oil pan if not the charger gets to hot.
FWIW Mike and I bolted the 2.8 pulley on my tvs yesterday and I lost a ton of power due to to much heat. Even with the single pass setup I was hitting 160+ AIT2's. Need a ported head to run that pulley size on pump gas safely.

Walbro high pressure fuel Pump, adjustable regulator, and increased fuel pressure to make my 60's flow a Static Flow Rate closer to 73 lb/hr
Make your own like I do since there is none available here. The whole kit costs around $1500 and you can make ethanol for about .50 to $1.00

Pump works fine. Ait2 's drop like a rock after a pull. As soon as I start getting over 22.5 psi heat skyrockets. Ait's are fine with 2.9 pulley, 2.8 is too much.
As far as making e-85 goes I know all about making booze I'm from the Prairies
. But my dad would consider it a waste to run something through the still and not drink it.

Actually I make e100, but if you feel the need to or live in a colder climate you can mix is with gasoline and make e85 or any combination. It is simpler than most people think. You have to get a permit which allows you to brew 10,000 gallons a year of test batches not to be sold. You can compost almost anything that sugar can be extracted from including leftovers after you cut your lawn. GREEN FTW
Just to be clear.. this is not a thread in which someone needs money donations or down payments to make something happen
this is a thread to gain interest and to see who would be interested in a 1.6L Twin screw blower..
this isnt a fantasy either.. in the next few weeks this will be on one of our cars
There are already blowers that have been made and purchased and are currently ready for testing on the car
the pirce will be a bit north of the Harrop TVS 1320 in the end but with a list of interest.. the 1.6L can be sped up through other sponsors.. again.. nothing out of your pocket.. just an interest poll
thanx
any comments are always welcome

Would be interested in this SC based on the test results. I want to stick with an SC and was hoping something else besides the 1320 would come along. At thsi point the 1320 is my only option when the 62 wears out.

Or at least making your existing displacement breathe better via a ported head, cams, OS valves. The pressure is a good idea of how much the air is "backed up" because the design and displacement of the engine won't let in ingest it fast and efficiently enough. Make the engine breathe better, the boost pressure drops, and so does the excessive heat. I don't think a larger blower is the remedy; it will just back up at a larger pulley diameter.

It's interesting that you see this crossover from power to heat in a relatively small pulley diameter drop.

The problem is the restriction. That's why he gets high on boost and high on temps.

I was just trying to make the point that if you're making excessive heat with the TVS, a bigger blower is not the remedy; engine modification is. Blower efficiency aside, a stock 2.0 LSJ is only going to be able to take so much air.
