Whatever happened to twin superchargers?

You can have a BOV plumbed back into the intake. That's not a huge issue. A SC kit is going to have a BOV open until you put your foot in it. It's not particularly quiet. No matter what kit you buy, access is a pain in the ***. There's just not a lot of room. I'm confused about the issue with the wastegates. If it's plumbed back into the exhaust, there's no additional noise. You can't have a turbo without a wastegate. There would be no way to keep from overboosting.

I substituted a bleeder valve for a wastegate, to eliminate the noise. It was continually dumping a tiny amount of pressure, to be sure, but wouldn't allow the pressure to go any higher than what I had it set for.

I didn't know about plumbing a wastegate into the exhaust...no one thought of that in the '80's! That might be an acceptable compromise.

He's talking about ooooooooooooold technology.

OP, get a turbo kit and go have fun. I'm surprised no one has suggested the AAM TT kit. Yes, it's more expensive, but solely based on the turbos they use, they claim to reduce lag even further than other setups.

Also, you need to catch up with modern turbo technology, and not stuff from over 2 decades ago!

Guess I'm not your typical "boy racer" -- maybe more in a Paul Newman kinda way!

OK, you all have convinced me to take another look at turbos. I'll have to ejimicate myself on the new tech. Question: what sorts of things could I get away with limiting the boost to, say, 8psi, that wouldn't be prudent at higher levels? Stock exhaust, or no? Still need bigger injectors and pump? Other things?

No matter what kind of forced induction you do, you'll need bigger injectors and pump. Not to mention the clutch, gauges, tuning, etc. You can run a stock exhaust with the Boosted Performance kit, but you lose the cats if that's a concern to you. It'll be a restriction, but the car will still be fast.
