Whatever happened to twin superchargers?

Thanks everyone for your helpful responses and experience! My thought was, if I went this route, to have a car fitted/tuned in Atlanta (5-6 hours from here). But having owned a car with a complex tune before, I understand the need to have a trusted shop locally for "issues." Based upon what you all are saying, perhaps the inherent liability gotchas would prohibit a sane person from taking this on in a location like mine.

One of the things I thought I understood about the TT cars was the difficulty in doing routine maintenance. Everything is up top with SC engines, and while tight, doable without dropping the tranny or engine-out? Did I get this right? The photos of everyone's engine bays blows me away! There's hardly room in there to squeeze a hand or wrench!

I can just picture a local mechanic with a car like this on a lift, with a beer in one hand and scratching his head. "Ya said the oil filter was where?"

When I had my Starion, I used a bleeder valve instead of a wastegate, primarily because I didn't want the pssshhh. Delicate and risky, to be sure, but it worked out OK. A wastegate on a TT would be a dealbreaker for me, and I know I wouldn't want to trust a bleeder valve on an exponentially more complicated and expensive engine/build. Anyone else use bleeder valves any longer? I think I read in one of the threads about an internal dump for a blow-off valve...perhaps an advantage for a quieter setup on a SC?

Is there an advantage, though, to engine response by having a twin unit instead of a single?

No argument there...but aspirated vs. non-aspirated. I would prefer NA, but the Nissan platform doesn't really offer the same potential as Porsche, for example.

Great idea to try to find someone locally -- I'll give that a whirl!
