Here it is
*most* of a detroit 3-71 blower. 500$ purchase on ebay, included a 100$ carb adapter for the top.
Initially I wanted a 6-71 or an 8-71 on top.. but.. $$$$$$. To get set up with a 6 or an 8 would of meant needing a real blower manifold (1200$), a dual carb setup, and spending who knows how much on getting custom pulleys made to under-drive the blower enough to only give my 4.8 5ish lbs of boost (would of needed almost a 75% underdrive lol)
Due to how boost adds up in a twincharged application I need most of my boost to come from the turbos. 14 pounds from the turbos going into a blower that does 5 pounds itself will net roughly 25psi total boost.
The 3-71 only displaces 210ish cubes, so getting my 5psi will be easy. The opening on the bottom of the blower is super conveniently just a whisker bigger than the opening on a 4bbl intake.. so I just need to have an adapter plate made and I'll be golden. Then it's just buying proper endplatess, a gear cover, piecing together a drive setup, and shipping it out to get rebuilt.
Twincharging is really super interesting. You get the best of both worlds with the drawbacks of neither. Your turbos will spool in half the time, detonation resistance somehow goes through the roof.. and your car will make ALLLLLLLLLL the cool noises. He'll yeah I'm excited.
Took a real quick measure and about half of the blower is going to be poking through the hood. Over half will be once it's all in the car.. I'm sure the adapter plate will add another inch or so to height at least. Sleeper status has been thrown down the toilet.. oh well. I'll definitely have the only twin turbo supercharged Caprice wagon in the state.. country... world? Probably.
