We even offered asylum to the best Nazi scientists and engineers if they agreed to come work for us. If you've never read up on it, look into Operation Paperclip. If they'd had more time and resources who knows how differently the war would have played out.
Centrifugal superchargers don't have the heat soak problems PD blowers do, and can blast away on a road course no problem. They'll still get hot if you stay in boost for long periods of time, but you're not constantly in boost on a track.
Buy a GT and put a centri blower on it. Easy install, cheaper than twin turbos, way less maintenance, great power and you still get that impeller woosh. If you get a loud BOV most people will think you have turbos anyway.
It's the bolt that holds the crank pulley to the crank shaft. It is vibrating loose while driving, most especially if I go past 3500rpm and enter boost. It needs to be tightened down after every drive or it keeps getting worse.
Maybe try a different bolt? I'm not sure what the shop put in there...
The crank pulley definitely loosens and starts making that noise again after getting into boost. I tighten it down when parked but it'll only stay tight for so long. I thought maybe the bolt was sized wrong?
I also saw this topic and hear what you're saying about having an incorrect pulley...
I tightened down everything that had a bolt and it ended up being the crank pulley making the sound. It was fine until a spirited drive and now the sound has returned. Could something be wrong with my crank pulley? There's only 4800 miles on it.
Thanks for your thoughts. I'm in Louisiana and still living in an RV after the last two hurricanes that hit Louisiana destroyed my house. We're all in the same capsized boat down here, but we're Louisiana strong! 💪
