anybody seen/tried this?

would love to see how this works out on an e34! :)

that is total crap. watch the videos, lots of noise, not a lot of go.

This kind of setup supposedly works pretty well. There was a thread on Bimmerforums about a month ago related to it, in the forced induction section. You can read Popular HotRodding's review of one of STS' kits here:

The turbo lag would have to be terrible. First you'd have to get enough exhaust gas pressure to spool up the turbo and thin the turbo would have to compress all the air in the intake before anything would happen at the engine. You could measure the response with an hourglass!

Turbos rock!

From the article, Popular Hotrodding:

"At this point you probably have more questions than answers, as did we when we first learned of remote-mount turbocharging. The biggest question on our mind was turbo lag. How is turbo lag avoided with the turbo so far back? According to STS, their systems are designed specially for remote mounting. They use custom sized housings that function awesome in back, but if mounted in the traditional location up front would perform less efficiently. On the flip side, if a traditional front-mounted turbo was moved to the rear, lag would become a major issue. We also wondered, doesn't it take a while to pressurize the intake tube with so many feet of intake tubing? To our surprise, a molecule of air can travel from the turbo to the intake inlet in .05 seconds, which provides boost almost instantaneously. "All the intake tubing adds up to less than half a cubic foot of space," says Rick Squires, owner of STS Turbo Systems."

Since there isn't an intercooler, I'd be willing to bet the intake pipe has less volume than a system with a decent intercooler, hence lag theoretically not so bad. It would still lose a bit on efficiency for any heat that is lost (from the exhaust stream as pressure) from manifold to the remote turbo...but, it's still putting out 5-20 pounds of boost...

i guess it makes sense for trucks, which have lots of room under them...
but for any other cars? i'd imagine scraping the turbo or knocking the
intake tube around wouldn't be good =\

[mikedev10]

they have apparently installed the kit on lowered camaros and had no problems. they claim it does not get any lower than anything stock down there.

[Craig]

They act like heat isn't a good thing for turbos. What exactly do they think turbos use to generate power? :)

I'm sure it's better than not having a turbo, but it sure seems like a lot of unnecessary work for a car like an E34. On a Camaro where you don't have the underhood room this might make more sense.

[bahnstormer]

at the same time though, the m30 engine/bay gets MIGHTY hot already.


just this system reviewed on 2 guys garage on speed tv...from 200ish hp
they jumped to 400....

nice little plug there :D

These style systems are actually pretty neat, Camaro and monte carlo owners have been doing them for a long time. you generally use a small turbo, and you'll notice boost figures aren't insane, but still, 10psi of boost is great, air moves along the feedback piping to the engine bay that an intercooler is usually note even necessary. the only part that sucks is the oil lines.

Also as seen in the pictures from their installation, they are running a muffler or at least a silencer, and they're also recirculating back into it rather than blowing off.
