Can Anyone Try Explain This?

[The Riddler]

Thanks.

er, they wanted a brace of turbos on their Jeep, but there is no room under bonnet - and they weren't bothered about the horrendous lag that those several metre long inlet pipes will cause?

[williamp]

Its a mess because the turbos are both of the same hand. If they have one left and one right hand it would be neater. But that far from the engine would give huge lag

[Boosted LS1]

Tailmount turbo's seem to work well with big v8's which produce plenty of exhaust gas.

[filski666]

looking at those nice low mounted air filters, they also wanted to destroy the wading capability of the vehicle too!

[filski666]

I bet it sounds good though!!!

It doesn't look like an off roader to me and those air filters could be nearly 3 feet from the ground knowing the size of some american vehicles. I'm fairly sure they'll have considered that aspect of the conversion.

Someone did that to an M5 too

it's a Jeep Cherokee, isn't it? Kind of an "off road" style vehicle I would say



plus the filters are positioned to catch all the mud and spray from the wheels

Yeh, I'm sure that'll see plenty of offroading, lol. It may cross a few curbs but it's hardly a landie.

Hey, somebody should tell Mel that a female horse is called a mare

no not a "proper off roader" - but certainly the kind of car that the owner would think - "yeah I can go through that huge puddle in my SUV" etc etc

which is all I meant by what I was saying, I think......hmmmm

As can be seen from the photo...that vehicle has seen a lot of "off road" use...

Probably the only off road it sees, is a drag strip.

Have seen this from the US before. As Boosted says they don't seem so fussed about lag with the big V8 + big car. Floor it and the V8 starts putting down big power then a while later you get even more...result.

What about oil and coolant feeds? Wont the exhaust gasses lose a st load of pressure before they hit the turbines? The turbo's, and intakes will be subject to a st load of 'weather' surely this could cause premature death of the units?

Yep. I can see a lot of downsides to installing the turbos there. Don't think I really understand the thought process that the installer went through in order to decide that that was the best position.

Guy was in PPC mag early this year with a turbo right at the back of the car. The tester claimed that lag wasn't noticably worse than on a normal installation.

Yep its a Remote/rear mounted turbo setup. They work pretty well on the BIG engined cars like V8s.

Pros of the system.

• Easy install
• No Cutting
• Reduced under bonnet temps (thanks to the hot bits being near the back)
• Potenically lower intake temps thansk to above, but dont think thats really that true!
• you can pretty much turbo anything out there!

Negative things.

• LAG - not as bad as you would imagine as long as you wrap the whole exhasut system and stick to stock manifolds not shotly or longtube headers
• Oiling - you have to run a remote electric oil pump to pump the oil back to the engine, these can brake an bugger up your turbos
• Power limitations due to exhaust - you often find you have to run restrictive exhauist housings to keep the spool time down. this limits the power than can be made with reasonable spool up.
• Power limitations due to inlet piping - again you find the intake piping is often pretty small. this CAN limit power potencial

There are lots of intresting things about these and other times of system LS1tech.com

Have a look at the site below for more info on rear/remote trubos - These guys are the biggest

Thanks Chris, thats the kind of answer I was looking for.

Nobody has ever said its the best positon...but is any turbo ever located in the best position ? No. Just where its easy for each person to install.

And these systems work. With auto transmissions and transbrakes etc...and of course big V8's, lag really isnt a concern
