Oh and the lower portion is back from the welder. Looks amazing, I just need to smooth down the welds and I'll be ready to work on the plenum body.

OK 
Welds inside the runners. I put a large v groove in the parts to ensure lots of penetration. The welding was done by a local fabricator that is much better at this type of welding then I am.
After about an hour with the die grinder everything is smoothed back out. I'll go over it tomorrow with a higher grit just to clean it up cosmetically. In the final picture you can set the outside of the runners. I really like the result of doing the welds this way and having the manifold look like one piece.

I managed to get some work on the plenum body done this weekend, including a very rough test fit on the car. Work is busy this week so I'll try to take some pics soon.

Out of the box you are correct, but with the newer rotors and an upgrade housing it has been done. If I remember right a few of the thunderbird guys are making 400+. Personally I'll just be happy to be able to take the car down the track this year.

Work has been hectic and the weather hasn't been great so I haven't done much on the manifold. I started welding up the plenum but still need to machine the top plate.
This weekend some friends came by and while poking at the car, one pointed out I might be able to fit the m90 on the OEM manifold with an adapter. I had all the cad files I needed to whip up a design so I made this up today.
I still plan on finishing the manifold, but this will work as a good solution for now. and also let's me start working on the pully's.

I have a 87 gxl na and a 89 supercoupe Thunderbird I was wondering if this was possible. the m90 can easily spin over stock setup by ford ( pulley ) not uncommon to see 5% and mostly 10% overdrive on them. I was getting 18lb boost on stock pulley and blew head gasket. with higher compression rotors more rpms and the fact it came off a 3.8l. I would think you need a turbo block or lower compression for it to not blow somewhere. Making your own pulley would help. Seems you have the resources to do so. I will be watching this closely.

I don't expect big numbers. I'm planning to keep things tame this year, and there is still a long list of work to do on the chassis.

I thought about that, but the SC 6 rib, I forget off the top of my head. I'm planning on either running 6 rib or dual 4 rib belts. I plan to under drive the water pump to prevent cavitation, and under drive the alt to save reduce parasitic drag.
