Spud's "The Definition of Ghetto-Rigged" M90 Supercharger Build Thread (lotsa pics)

[Spudchucker]

Got a few updates here, though it may not be the stuff you guys are looking for Definitely necessary though.. I replaced my brake pads on Saturday, along with changing the oil (Castrol Syntec 5w30), using quality ZALINSKI AUTO PARTS from their new innovative brakepad division. (ok, they were cheap ebay pads and a FRAM filter lol). Yesterday I installed some NGK Iridium spark plugs as well, though I couldn't do the wires because for some reason the Autozone I went to didn't have any, despite a whole wall of wires. Incidentally, just how important is it to change the wires with the plugs?

As for the hood, I bought a huge bag of plaster, and I am going to finish it off with the workability of said plaster, then make a new fiberglass shell with the exact dimensions ready to mold. My hood probably weighs 80 pounds with all the bondo on it right now, and aside from the weight, I don't want to to blow up like a bag of flour if I ever bump anything I'm not sure when that will get done, but I'm hard on the trail again since my tune is going awesome now.


Also, I'm LOVING the colder weather with my car's performance! In the summer, I could barely hit 5.02psi on a hard pull, and at 50 degrees outside now, I'm approaching 5.5-6psi regularly. Every time a new cold front moves in, my car goes faster I'm still undecided on whether or not to do chain drive or a fat pulley, but I don't need to worry about that for a few months anyway, as I would need to build the motor up first.

No need to do your wires every time you do yoru plugs. The OEM wires are of pretty decent quality, and last far far longer than a standard plug. Especially a copper plug. I don't remember the exact number, but I think Subaru recommends replacing the wires at 50k intervals. But, don't quote me on that.

Wassup peeps I've been hugely busy and haven't been able to do much on the car or the internet aside from pouring over the tune day in and day out (I can honestly say I know my car's brain like my own now lol, and 0-3,500 RPMs is tuned about 95% of the way.. Just working out some subtle blips that randomly happen) I've developed an entirely unique system for OpenSourcing a NA 06 into boost and I will happily share it, but it's a fair amount of writing and screenshots to do so I can't promise anything right away until some other projects I'm doing die down a bit. If the Access Port still isn't available for NA 06-07 (is it? I'm out of the loop) because of their issues with tuning for boost, then I'm pretty sure I know what they were messing up on and have found a beautiful, albeit time consuming, way to make everything mesh perfectly.

And just for a small update, I have a Wideband now, it's just not installed yet, and I also had to remove the fiberglass cover a month or two ago (no worries, it wasn't finished because screw fiberglassing/bondoing outside in the winter lol) because apparently it's illegal to have a 5"+ cowl, while at the same time it's perfectly legal to have dangerous spinning parts sticking out of the hood if they're part of the engine


I have a lot to do so I can't elaborate for the moment, but I'll be back sometime soon to add some knowledge I've been picking up since my last post. My car feels more or less like a pre-06 WRX pulling out, only the power starts straight from 2k RPMs instead of 3.5, so things are good. Keep on supercharging your scoobies people!

It's only "illegal" because it's not finished and doesn't look that good right now. Lots of people have cowl induction hoods or superchargers sticking out of the hood and they never get crap about visibility in NH. Over the years I've come to realize that the better your car looks, the less likely the police are to enforce laws regarding modifications. I hope you didn't get any tickets!

ha! its the same in ca

No, it's because the cowl was too big.

I drove around like that for several months without any police incident (never even mentioned as questionable, even when I had no bumper), the reason it was called out was because the person inspecting my car said the legal limit was 4" in front and 5" in the back and, I had to take it off to pass. The blower is fine as is because it's attached to the engine, it's the hood itself that is limited

And my car definitely looks pretty ghetto right now, but no one seems to realize it- It's such a freak on the road that a chopped up and sanded hood with bondo chunks on it doesn't even register on many first sightings haha, I've even literally gotten into arguments with people insisting my car is over 300 horsepower


Lol if ricers really wanted people to think they have fast cars, they would glue a blower on their engine and cut a hole in their hood

[corndog]

damn I have to see this hood get completed or I will die!
