Magnacharger fits F-Body!! Well.....as long as it's an LS1 3rd Gen!! 
Decided to play with a Magnacharger Radix system on our 91 LS1 Z28. This is the kit designed for the trucks.
During the install I pulled the Comp 222/222 cam and the Yank PT4400 and substituted a LPE GT2-3 cam and a Yank 3000 converter.
After getting it installed, up and running, and tuned in a little, I took it out to the track Wed. night for a few shakedown runs.
Run 1: 11.12 @ 123.60 1.564 60'
Run 2: 11.17 @ 123.49 1.599 60'
Run 3: 11.17 @ 124.37 1.608 60'
Run 4: 11.24 @ 124.22 1.675 60'
This is at only 6.5# of boost. I'm going to drop the pulley size down and try and get it up to about 8#.
I had the tune set up as follows:
6200 RPM shift points
18 deg spark at WOT
11.2 - 11.4 AFR
This seemed to work pretty well. I had 2 deg of KR on the first run on the 2-3 shift, but didn't have any more KR the rest of the night.
I may try another cam or 2 after I get this all sorted out. I don't think it'll do any good to go too crazy, as the Magnacharger isn't a very big compressor. I think if I can get the boost up a little, it should run easy 10's on a car that idles like stock at 700 rpm!
The thing is a blast to drive! On a little WOT testing in front of the shop, one of the neighbors said it sounded like a jet going by!
Don't worry, I've got a new hood ordered from VFN!
Still running stock exhaust manifolds......

Thanks guys.
Yes, this is the intercooled setup.
I'm going with a VFN "Mike Bowman" style of cowl hood. Because of the Radix layout I needed something wider than a regular cowl induction hood. This hood tapers wider as it goes back, and looks like it will cover everything. The only problems is that it also gets HIGHER as it goes back; I don't know if I can live with that for very long......we'll see. It's on order so I should have it in a couple of weeks.
GOOD headers will NOT fit this car, that's why I'm still running the stockers.
I picked up another 3rd gen for some R&D work. I'm going to see what it would take to fit a 4th gen K-member in this thing. What a leap forward that would be if it could be modified to fit! Headers, R&P steering, light weight parts, etc.

Man I wish we could fit one of those on the 4th gens without hacking the cowl. Those are some awesome track times too.
you should look into this hood it's called the jongbloed hood

rons, as far as I know, that hood is unavailable. It looks AWESOME I think. about a year ago, some people over on thirdgen.org were trying to get an amount of people who would go in on a hood like that. There was a member (that blue car you have pictured in fact) that was on the board and was willing to lend the hood as a model, to get a new production run.

That hood looks good. It's hard to tell with a weird setup like this. Because of the pulley you need a lot of height quickly, and then not much towards the back of the hood. I'll keep that one in mind if the VFN hood does not work out. Thanks.
I think it's an M112 blower. I believe the pre-Radix compressors were M90's.

Yeah, I think if you could adapt the new Eaton compressor from the ford GT (M140?), this thing could make some serious horsepower.

Very cool!
I would run a hood with a front scoop like a SLP 4th gen UltraZ type hood and i would run the air intake from the hood to the intake. That would remove the diagonal clearancing you had to do for the bellows.
