There are electric superchargers that use a bank of batteries to power it, but the problem is it adds a lot of weight. The problem with electric is the amount of power required to compress the air. When you're talking say 14psi boost at 400CFM flow, that takes many horsepower to compress the air. So that might take who knows, 1000 amperes at 12 volts? That'd be 12kw. Plus the cost of a 12kw 12VDC motor is not going to be cheap, plus heavy.

Sometimes when the value of Al scrap is up you can get a few $ by taking radiators, old water pumps, stuff like that in. Usually price is better for 'clean' scrap, i.e. you removing any plastic and stuff like that from it first. Or maybe you could rig up an older supercharger to it. There was a guy on here who had an old Mercedes supercharger set up to run off the power steering belt. Then you could route that through your intercooler.

Probably. It's just going to increase pressure drop in the intake, making it less efficient. The intercooler on a turbo engine is to knock out or reject the heat of compression from the turbo when it is in boost. Cooler air is denser, and thus with more air into the engine, more fuel can also be injected, and give more power. But on the n/a engine, there is no heat of compression because there is no turbo, so provided the existing intake is taking air from the fender or just under the hood lip, it's already going to be pret near ambient temp, and the intercooler will not reduce the intake air temp at all, and hence will just add restriction/pressure drop to the intake.

Thank you all very much for the help. I tried tightening the axle nut, it's probably a bit snug at around 170 ft-lb now. That seems to reduce it a little bit, but it is still slightly sloppy. I have the bearing kit on the way and just picked up the HF front wheel bearing adapters with the 20% off coupon. Thanks for the offer on the 1/2 price set Rooster, I just picked up the set at the store before seeing the thread.....suppose I could return this one though. I'll see how it feels after the brake stuff is off and the axle is out.

I can feel a little bit of looseness when shaking the front right wheel on '00 Outback 175k miles. Ball joint, strut, and tie rod end are all tight. I can still feel the looseness in the hub just a little bit even with the wheel off. When spinning the wheel and feeling the strut spring, or using a stethoscope on the spring, I do not hear any grinding or abnormal noise at all. I guess that's the part I'm confused about, it seems for wheel bearings people usually say there will be a grinding or rumbling? I don't notice any grinding or anything, even in turns (though it does seem to have a pretty good shimmy/shaking in the steering wheel that comes and goes). Snugging up the axle nut a bit seems to make it a bit less loose....maybe that is the telltale sign?

Woohoo congrats! You know one thing I love about the '96 - it resets all inspection I/M's every time the key is turned off, so it gets exempted from needing to have them set. That means if you have a CEL problem, if you can unhook the battery and reconnect it, and start it, and the light stays off, you can pass basic inspection! (Normally you can't do that, because then the I/M's are not ready after unhooking the batt).

Well it's not that the manufacturers want to warranty emissions that long. Our friendly government requires it I believe, because the know individuals are say 93% more likely to not get it fixed or try to circumvent it if they have to pay for it out of their own pocket. We all pay for it in the end anyway.
