rear mount or "remote-mount-turbo"

ummm no..

edit: it looks like it would be cheaper and less effort to just put a turbo in the engine bay from that photo???

[diss7]

I wouldn't be so quick to dismiss. I personally would like to see/drive one first hand.

There are numerous benefits
Better weight distribution would be one I don't see mentioned.

But then theres also, oil feed and drain. Maybe theres a seperate turbo oil pump.
Lag? The compressed air needs to go all the way back to the front of the car, and still needs to be cooled. Although an underca water-barrell i/c would be the way to go.
Answers are probably on the website- cbf.

been done numerous times where there is no room in the engine bay to fit more equipment

[xsspeed]

Negs that I can see

Extra piping (air and oil)
Turbo's get hot, dont park over dry leaves
Need to change filters heaps
What happens when its wet/puddles?
Turbo's get hot, close to fuel tank
Larger debris could easily take out a turbo, filter, oil line etc

Probably suit a mid/rear mounted engine setup better?

Done because laws say they cannot alter the exhaust system before the cat converter.

how can you patent putting a turbo in the back...

"you i just put a turbo in the back of my car"
wait bro... you know thats patent!

[thegreatestben]

Watched a vid on this a year or two ago, apparently with the pipes being as long they are, they actually get cooler charge temperatures, and because they are usually fitted to big dirty eights, they don't suffer from lag that badly.

Can't see why it wouldnt work.

[pjay]

With all the air rushing under there id say they would be fairly cool

[holden_fan2005]

A guy I know has one a system like that on his V8 SS commy. Until you guys can suggest where in the engine bay you can fit a turbo I think this is a great idea!

His car had very little if no lag and it seemd to hall ass.

It goes in place of the muffler so its not exactly sticking out like dogs balls either.

I found this part.... Interesting...

I notice they didn't mention twin screw superchargers... Heh

I'm interested to see their solution to the oiling problems...

Has many advantages in cost and complexity of installation, for a DIY kit this is far more straightforward than turbos in the engine bay. Lag wouldn't be a problem, people overestimate the effect piping runs have.. the time required for the turbo to pressurise those lines is infinitesimal. Intercoolers wouldn't be an absolute necessity either as the turbos themselves would run MUCH cooler and you have a pretty good length of very well cooled alloy pipe between them and the intake manifold.

turbos mostly get hot because they have hot exhaust gases running through them, the gases would be cooler by the time they get to the rear of the car, so it shouldn't be as much of a problem. Exhausts can get pretty hot and I haven't seen many people worry about them being near the fuel tank. Same deal for leaves etc (although there was that incident at the four and rotary nationals...)

I kinda like the idea, it's not perfect but in some situations it's probably a better compromise than putting a turbo in the enginebay

[flygt4]

reasonably common system in the states in corvettes etc. theres nothin wrong with it, its just a different way to do things.

the turbos end up way more efficient too as the air they are compressing is much cooler to start with.
I think they also don't need intercoolers due to the air being cooled on the way to the engine.

[xsspeed]

True I was more thinking of the gas being the same temp as at combustion chamber exit which is wrong you are right.
Was purely pointing out the negs I saw though, I found it quite interesting regardless, had never heard of it

[Adydas]

one negative no one seems to have considerd is the theft risk..

If its only bolted on using the same tools as removing the mags you could potentially (unless its welded) remove the turbos and get away with a steal mish on one.

Not likely i wouldnt imagine , to time consuming and a risk etc but still more possible than the likelyhood of somthing taking your turbo from the engine bay..

...but where are thieves most likely to look for a turbo?

[Snaps]

^^ Good point

[cat007]

Correct me if I'm wrong here - but exhaust gasses move fastest when hot? i.e. one of the main reasons for heat wrapping and "turbo beanies"?

So by the time the gasses have travelled to the rear of the car?......

[molex]

That's why the A/R of the turbos is quite a bit different from what you'd normally be running. The same volume of exhaust is flowing, but velocity drops and heat drops. Utilising a smaller A/R remote mounted extracts the same amount of puff as a larger one at the headers would.
