Let's talk remote mounted turbos...

i think we're all think in the wrong direction, instead of far back what about far forward, as in under the passenger side headlight or something?

I'd see heat being an issue there. It'd have to be well insulated or stuff is going to melt. However, I suppose it's a possibility given enough room.

I'd be OK with lag if it meant I would have a turbo on my car. A 4 port is near the same as a 6 port low end without boost and even with a laggy turbo the turbo-ed car would still be faster.

I think lag could be negated with a properly sized turbine housing for the smaller amount of heat.

In reality though, lag even on giant T6 turbo's is a moot point. Anyone who's going to flog the car isn't going to do so from 1800rpm - you're going to floor the fuckign nuts off it.

IMHO though, there's way too much room in the engine bay to consider re-engineering the turbo system for this type of mounting.

I can see why they'd want to keep that cramped engine bay away from a turbo but the FC hs plenty of room. Either in the stock position or with a custom manifold that moves the turbo forward.

When I was still using a Thrush Turbo muffler as a midpipe on my otherwise open 2.5" exhaust (w/ two mufflers after a y-pipe) I was able to creep to 12psi boost for a brief moment, but then it'd plummet down to 5-6psi, even in the high gears. That Thrush pos reduces to about 1.75" inside, yet I was able to hit some wicked boost (but only for a moment) before all that air got compressed into the three feet of pipe before the restriction point. I don't doubt this would work similarly, but with even worse effects. First, when you romp on the throttle you won't boost quickly, your basically NA motor will be fighting to cram a bunch of air to drive a turbine (which will certainly resist, and more so as it spins faster). So then, once it's actually spooling, the turbo will have to play the same game to get the compressed intake charge into the chambers. I would bet that such a system may not benefit you AT ALL in first or second gear, and maybe minimally in third. And when you shift, your compressed intake charge will have to be vented and the only thing you'll have going for you is the turbo is at least still halfway spooled up. I'd be curious to see this done just for kicks, but I don't see any real practicality in it. Compared with a standard under-hood turbo setup, you'd almost certainly sacrifice power gains, you'd fight things like lag, it could end up costing more than if you'd just used an intercooler (look at all the labor and piping it takes to do this)...

have you been alseep for the past few years? have you not seen the remote mount turbo kits companies are producing and how rediculously fast they spool. remember, rotary's put out just as much exhaust as most 6 cylinders and some v-8s. also remember that the cooler air gets the more dense it becomes. so actually you are wrong in saying it "wont make boost in 1st or 2nd" haha. thats why long runner manifolds(underhood) spool faster that shorty's or that shitty cast iron block of a stocker you are running.

i think this would be fantastic and have been wondering why no one has tried it yet. good luck

No, I just haven't done research, and this is the first time I've heard of this in a serious context.
