Mock-up Supercharger is here! PIX (Progress thread)

only in kentucky...lol anyhow nice progress thus far, it will come down to the math I believe, and you may just want an engine damper or something to stabilize the puppy with all that extra wieght. Warranty Voided, lol.

Only in Kentucky? I, sir, am not a redneck.
Weight gained will be around 30 lbs.. I hope the frame doesn't buckle!! "Warranty Voided, lol" Oh snap, for real? I'm going to lose my warranty!? AHH!!! ;) Relax, I'm well aware my friend.
Thanks for the encouragement to the rest of you.
I have taken all the measurments needed and am drafting the setup in Autocad next week. I'll be prototyping parts shortly after. I have about 5 weeks to go yet as I want it to be very easy to install.
If anyone wants to help by finding out for me how to get a hold of the alternator pully that the greedy kits come with that would be great. I'm planning on making my own but why reinvent what's been done.

wasn't alluding so much to redneck as I was the Dukes of Hazard type crew, tinker, tinker, bam! Yeeeehaaawww! lol, i've had my laugh. good luck, i want a cheap supercharge for my car too.

My main question.....
Knowing you are only running about 6psi with this thing, do you have to upgrade the fuel system or can the stock fuel system and ECU handle this?
I mean we are only talking about 6psi.
I ask this because I am starting research on building a S/C system for my xB but going a slightly more expensive and ALOT noisier route by using a Lysholm blower. I plan on this blower putting out about 8psi and I am trying to find out if I really need to make changes to the fuel system and whatnot.
Sorry if I asked this in a couple spots. I want to get a number of opinions.

As in other threads, I think 8 is stretching it after running the numbers and equations. I have all the figures at home (at work right now) and they all point to ~4-6 being the butter without having to really get into the thick of it.
Because it is returnless on the fuel system the fuel pressure doesn't rise with boost, it will stay a constant 43psi(I think?) at all times. If you don't raise the fuel pressure with boost you are asking for trouble. Now 6psi on a 1.5L engine isn't pushing a gigantic amount more air and as such the fuel should be able to keep up.
Fuel required for 6psi on a 7L engine is much different than 6psi on a 1.5L engine. Our injectors are small but can support more HP than stock. The only thing I DON'T yet know is how the MAF tables are setup in the ECU and how much air will run them off the top and max out the table. That = bad. A spoof of the MAF signal that scales it in relation to the size of the new injectors when installed sounds like the best option. A return feed and rising rate FPR still needs to be put in.
Hence, I intend to stay low boost to run the shake downs and make sure it's all skippy before going crazy on it with fuel additions and everything.
Besides, I don't like to wind out my engine to 6+grand, I'd rather have 200ftlbs of torque from 2k-4k and shift to the next gear. I'm doing this because this car can't get out of it's own way below 3500rpm and that sucks!

I talked to my friend more and he can make an electronic device to control a 5th injector. With this device and the 5th injector the motor with stock fueling and ECU should be able to handle 180hp.
I'll get to work with him on this device. In the meantime I am sourcing out an M62 blower for my ride.

Ok, BoogieQ,
My friend and I have done the research that needs to be done for the 5th injector and controller. This will allow the fuel system to remain stock, you simply tap into the fuel pressure regulator and run a 5th fuel line to an added injector. This injector will sit in the intake tract just BEFORE the throttle body.
So what I would love to see are some more final mounting locations and the plumbing so I can see what all I need to get my hands on to mound plumb a 5th injector into the system.
I am still trying to locate an M62 blower at a reasonable price, once I have done that I will be mountiing min blower up.
I also have a friend that can mill me an alternator pulley that has a place for the S/C belt.
This is gonna rock.
