"remote" turbo setups?

[Jase]

Hey all

anyone here seen a car fitted with one of these?

basically the turbo is mounted at the rear of the car, or in the boot.

Run no mufflers or cats, and a adapter to allow the turbo to bolt onto the end of the exhaust, then out thought to dump
Elimintaes expensive custom headers.

There would obviously be a bit of lag having the turbo so far away, but on a 351 (read next car), theres no shortage of exhaust gas.

And the plumbing back to the intake is roughtly as long as the plumbing in a car running a intercooler. And it also has a simluar effect.

The turbo also runs a bit cooler bening so far back, and a seperate oil cooling system can be added if wanted.

On a LPG only car you have the whole fuel tank area to mount something like this, or you could put it in the boot through the fuel pump hole or what ever


Anyway, anyone have any experience with these?
Photos or what ever?
See any potential problems? (apart from the air intake being so close to the ground in picture below)



heres a site for someone who does something simular in the US

dude doing it to a mustang

[Milhouse]

its got about 30ft of intercooler pipes, seems a bit stupid to me :)

it's completely inefficiant unless there is zero space in the engine bay.

And...judging by the amount of time my exhaust spends scraping on speed bumps etc i'd say that set up wont last long.

Plus the lag and pressure drop must be rediculous...you'd almost want a booster turbo half way!! ha ha ha

[Jase]

you have ALOT more lag with out turbos :P

Could make a drop tank style thing to house it all in?
just waiting for dyno result to be posted in that mustang thread

[Jase]

could you run smaler than usual return pipes to keep velocity up a bit?
or would that just cause a bottleneck?

Just get a proper car that began life with a turbo.

The only thing i have seen an example on was a V8 XF Falcon or something like that. Becoz its hard to run a single turbo in the engine bay.

How do you get turbo lag without a turbo?
Do something like Eddie Tassone - His turbos are in the engine bay.

Non-turbo cars are the laggiest of all....they never hit boost ;)

Theres one big complication with this style of setup. Because the turbo sits below the sump's level.. and so far from the sump.. the oil must drain out of the turbo into a reservior mounted LOWER than the turbo... which has a scavenge type oil pump as used on dry sumps to pump the oil back to the motor.

Personally, I'd much rather weld up some custom headers than go through the BS associated with oiling a rear mounted turbo.

Its only really a decent option where engine bay space is too limited to fit a turbo.. and theres no other way. The power potential of running turbos in the engine bay is far greater, theres not nearly as much exhaust energy lost. And more exhaust energy lost = higher required pressure at the MOTOR to spin the turbo = less power.

So dont go thinking that lag is the only 'con' of this kind of setup. Its crap in every way. And the little things like a cooler running turbo mean nothing.. All of us jap car ricers have no problem with overheating turbos in our claustrophobic engine bays :)

yeh id stay away from it, the cost of piping to the rear, oiling setup, lag, etc isnt worth it.

put the turbos in the engine bay or like APS's setup for the TT Boss XR8/GT's and TT Ls1.

it may get results but youd get better results with a proper setup and not some compromise.

the two major drawbacks is much less heat and energy to spin the turbine which equals less power and more lag. 5x longer intake length which equals more lag again.

yes i dont like it

[Brockas]

But with this setup you're introducing a restriction in the exhaust, which makes it more of a slug than it currently is off boost.

Making 'expensive' turbo manifolds will be a whole lot less costly in the end, especially when you consider how much piping you need with that **** setup.

[pshrdeta]

To extend on what brokas just said throttle throttle response would be average

[Jase]

yeah just though Id see if anyone had seen one.

Saw a pic of one on a old fairlane about 6 months ago... just wondered what the go is.

obviously there is a few huge dissadvantages with one.. esp the one in the first pic.

Just thought Id get some info on it.
Id personally go for a couple lil s/c if low cost boost was my goal. only seen the particular setup done once on a large V8, but worked well

jebus did anyone else notice the bell muoth with no air filter behind the rear tyres mmm lovely diet of rocks rubber the tyre smoke.

Some people don't deserve cars.

[S_E]

I'm interested to know what power the car above makes...

Whell guys, i went to the dyno yesterday and on the first pull, the wastegates failed to open....he caught it at around 15 psi....i was like holy ****ttt!! I looked at the dyno and it said 500HP to the wheels.....uh oh..Anyhow, turns out the boost controller i had was messed up, so i just had to connect the wastegates straight up and it makes a constant 5lbs of boost now. It made 331hp/380TQ at the wheels at the 5psi...and wow is it alot faster than it was...but when i get a new boost controller UP IT GOES lol...Its nice...DEZ racing did a great job tuning it, and it runs just like it did before just much faster. He pulled up the old dyno sheets and i was making 270hp/305/tq before N/a. Right now, i still have to finish making a skid plate, and my rear seat delete. I WILL get vids soon

theres his results of the mustang from the link in my second post. At 5psi, not too bad. wanna see what happens when they tune it to some decent boost figures
