hmmm in the entire galaxy?
Look forward to seeing pics!
According to Han Solo.
The car is dirty, but I took some pics this morning anyways...
The Supercharger...
The Water/Methanol Injection System (Snow Performance)
The Headers...
The Intercooler...

16psi. How big is that FMIC? How much psi do you think your sacraficing with it? Have you ever ran just a straight charge pipe without the FMIC? Whats the diameter of your piping? Did you ever measure the charge temps at the throttle?
The V2 S-trim was only rated to spin 16-18 psi max correct?
Sorry for all the questions
I have a very similiar setup, curious to see you numbers/results.

The S-trim is rated to 680hp (1000CFM) and 20 PSI.thread jack 101

The FMIC is 24"x12"x3" and I think I'm losing about 4 psi (about a 20% pressure loss from 20 psi). I assumed this based on the V2 S-Trim's max psi being 20 and my impeller speed being at it's max too with a 2.90" pulley. It's actually a bit over the 50,000 rpm max recomended impeller speed. Assuming there's zero belt slippage, in my case, the impeller will reach 50,000 rpm @ 6,713 engine rpm and 52,137 rpm @ 7,000 engine rpm (diameter of crank shaft pulley in inches x 3.60 x engine rpm at shift point divided by diameter of supercharger pulley = impeller speed). I asked the Vortech guys about the overspinning and they said it'll be fine since there's probably some belt slippage, but if not, it'll only be over the max for a brief moment for the last 300 or so engine rpm's (I shift at 7,000 rpm).
Before I got the FMIC, I had a 3.48" pulley and I was getting 12 psi. After the FMIC was installed it dropped to about 9-10 psi (about a 20% pressure loss from 12 psi). I put in a 2.87" Vortech pulley and the belt slipped like crazy and the boost dropped to 7 psi. Luckily Lupo from the SHO Cal forum let me know about the Reichard Racing Ultra Grip pulley so I picked up a 2.90" and have been seeing 16-17 psi @ 7,000 rpm ever since. I couldn't get a counterclockwise rotating pulley, but the clockwise one is working just fine. My piping diameter is 2.5" from the supercharger to the FMIC inlet, then 3" from the outlet to the 80 mm MAF. My ACT sensor isn't connected yet to the intake so I've never measured the charge temps at the throttle. I'd like to hook it up before I get it tuned/dynoed. I just picked up an 80 mm LMAF for $36 on ebay to replace the Linc 80 that I currently have, but I'm thinking now I might need a 90 mm LMAF instead, but maybe not since I'm at about 5,000 ft elevation here in Utah.
What size pulley do you have and what kind of boost are you seeing? How big is your piping? Do you know of any good SHO tuners in Utah, or a surrounding area? Right now I'm still running off of an old SHO Shop tune.

Thanks.
Thanks.
Thanks.
No thanks.
And good luck driving it away too. Those pics were taken about 10 mins before the tow truck arrived yesterday morning. I found out today a bearing broke loose and shot through the transmission case which explains the leaking fluid. I expected something to happen with the tranny sooner or later. It lasted about a month with the increased boost, but it was BY FAR the best month I've had with the car for the past 6+ years that I've owned it (and been building it). The wheels are 17"x8" SSR Competitions. I couldn't find what I wanted in a 5x108 mm bolt pattern and I was lucky enough to find out that a 5x114.3 can be machined to a 5x108. It's was $60 per wheel for the machining, $10 for each hub ring, and the structural integrity has remained. There's a lot more wheel options with a 5x114.3 vs a 5x108; Volks etc. Now that's something I'd like to see; Volks on a SHO. Too expensive for me so I settled for the SSR's. The 38 mm offset and 14.5 lb weight was perfect too.

Boost is a measure of restriction. The V2-SQ that we use isn't even breaking a sweat at 9psi (stock engine). The limits have to do with compressor speed more than anything else. You can't over spin them or bad things happen. Vortech has a compressor shaft speed formula that takes into account max rpm and pulley sizes. The amount of boost that a particular blower combination makes is solely Dependant on the size of the hole you're trying to fill. I'll give an example.
We did a blower on a '04 Marauder. The car put 375hp to the ground at 10psi. Took the owner 4 months to break it. He actually pulled the top off of a piston. The remaining pieces went everywhere and kicked the crap out of the inside of the engine. We installed forged rods and forged low compression pistons, then ported the heads. So the compression went from 10:1 to 8.5:1 along with much better flow numbers on the heads. What we found with retuning was interesting. The car only made 7psi of boost, yet still put 375hp on the tires. We could run a butt-load more timing and make power, but without changing the blower drive in any way, the car made less boost.
Got another one going together with low compression pistons. We'll be turning the blower a little harder for this one.
Pressure drop of a charge air cooler (that's what they are caller) has a little to do with restriction to air passing thru it. It has more to do with the thermal efficiency of the charge air cooler. As the air passes thru the cooler and releases it's latent heat, the more dense the air becomes. As the temp goes down and the air density goes up, the pressure must go down. So the better the charge air cooler, the lower the pressure will be on the outlet side.

How exactly did they do this? Did they round out the holes? I'm curious...

I realize that and I've met people that have had that done, but his description says that the 5x114.3 can be machined to the 5x108 implying that somehow the wheel was modified for the 5x108. Seperate discussion.

My point is that if you look at his wheels there aren't extra holes. If what he said is what I'm reading, that he had a set of 5x114.3mm wheels machined to 5x108mm what do the holes look like? How are the lugs sitting? Do you even understand what I'm asking?
I know exactly what what you're saying, however, did you not bother to read that I didn't even quote the drilling of the other pattern? Negative. I made a statement about getting a pattern done from the factory. Take it for what it's worth, but get the *** off my case.
Perhaps you are trying to simplify it to layman's terms, but it is an oversimplification to be sure. There are a myriad of factors involved, as I am sure you are aware.
Essentially, what you are saying is that cooler air equals less boost pressure, and that the better the intercooler, the more pressure drop it will have. Increasing the thermal efficiency of a particular intercooler will not result in a drop in boost pressure. When spraying my intercooler with nitrous, the resultant cooler air charge did not decrease my boost pressure (as measure at the manifold), but it did increase power by 40whp.
