RemoteMount Turbo- Yeay, Neays?

[DatSRBoi]

I been reading allot on how people custom mount their turbos allot lately and I saw this one company that got me thinking WTheck? I been seeing allot lately how people mount their turbos UNDER the car in the back allot. I can see the dangers of it like more dirt to suck in, road debries, and more pipings. Benefits I see are that you dont mess with the engine bay, and less heat.... Interesting stuff. Whats your guys input on these? I see ALLOT of muscle cars rolling around with this from corvettes to LS# camaros. They seem to like it more then under the hoods on their 40 grand plus cars. Even one truck in my area has it and on SRT4 all custom out.

Really nice setup !!

so basicly it suck out the air flow better so a better input air flow, isn't it ?

Interesting....never saw anything like that before. With it out of the engine bay you would seem to get cooler air and save $$ on an intercooler.

I was told by one of the corvette owner that it works just like a normal turbo but with less issues OTHER then its under the car. But his intake is mounted higher into the car so it doesnt cause rain suckin water issue nor dirt. The car performs better then his older corvette where the turbo was inside the engine bay. Only thing he is scared of are road debries slamming onto the turbo like blown tires and huge rocks. Performance wise he told me I shuold do it that way because its allot easier to mantain and caused him less issue.. I would understand him. Two turbo corvette? And his car is worked at some of the best shop in my area... Id listen to him shootz.. 40Grand plus car.... No joke.. Now if it was some honda then I wouldnt. But a corvette owner..

the moment when the water splash into your air filter, it is the time to get a new turbo.

i believe this application is for drag racing only

Because there is so much more plumbing to have the turbo in the rear, you will not get the output of the same setup in the engine bay.

As for not needing an intercooler: as you compress your intake air, it gets hotter and loses density. You intercool to remove some of this heat generated during compression.

Sure, your air might be a bit cooler, coming from the bottom of the car instead of the engine bay, but you would still benefit from intercooling. Of course, the loooong pipe running from the rear of the car up to the engine will dissapate some of that heat... I would think that you could weld a heat sink to the tube and get a bit more cooling.

I don;t like this for performance, but I'll bet you could smoke some suckers if the setup can be hidden like this. Kind of like having a hidden NOS system with no visible plumbing or bottle.

No the kits come with intercoolers too. That STS and Mr. 5010 or what ever he's call are builting one for the accord. Although I think they will drop it again.

Yawning,

Cool setup, but I would be afraid of its longevity, the turbo is exposed to the elements, not a good thing, considering the air has more piping to run through, which could cause a drop in PSI at the throttlebody.

Lets not mention if you get a flash flood, and it sucks up water.... terrible thing to waist.

all the extra plumbing would be a possible problem for a daily driver.

Yawning,

'Sup with the "yawn" - staying up too late or just hungover?

That's a cool setup! I would definitely get the intake mounted higher though - like up in the wheel well or something... maybe up in the rear quarter panel and vent it with scoop or louvers of some kind... hmmm... gets me thinking...

I would also consider some kind of skid plate to protect the unit from debris - they do it on off-roaders all the time - no big deal.

Hey Phreak - any input o Exhaust Master?

Remote turbos - nay, and why?

Having said that, I still respect the work people have put into those set-ups. I guess I don't understand why someone would want to go to the trouble, it is different, but certainly not as efficient as conventional turbo set-ups. For me, it makes sense to just buy a factory turbo car and modify it from there. A turbo corvette? Don't get it, headers, cams, ECU flash should give somebody more than enough reliable power, if not, weight reduction. I just like the basics.

Too much piping. All motor is better anyway

I agree. I dont know if mounting a turbo under the car is that smart of an idea, to me it just sounds a little.. stupid. just me $0.02

Main issues with this....

-Most people who are heavy into turbo know that retaining the heat of exhaust before the tubo is a good thing for boost. As the air cools, it becomes more dense...(we know this from intercoolers) but it also slows down... What does this cause in a remote turbo situation???? More LAG.
So ontop of the fact that you have Lag from the incredibly long piping, intercooler, ect... you have lag from the time the exhaust leaves the valves and the engine, to the time it gets to the turbo.
The only plus I can see to this is that the exhaust at a further backlocation is no longer in pulses per-se, but is more of a flow. That means that the impeller of the turbo will see a more steady flow of air to spool with.

-Issue 2... A turbo needs lubrication and cooling. You place that thing in the rear, that far from the engine... You will need to pump the oil (and coolant if equipped) back to the engine. Any stock turbo usually places the turbo up heigh compared to the oil pan, and simply uses gravity to drain it from the turbo, when a metered amount is supplied from the oil pump/lubrication system. If its back there, and the engine is up here.... there is no chance in hell of gravity doing the job, you need a remote pump. and if that pump fails???? you blow your turbo.
-Issue 2.2.... The fact that the oil can cool by the time it reaches the turbo, heat up at the turbo, cool by the time it gets back to the oil pan, and heat up in the engine.... MAY (possibility exists) help premote oil sludging.


I'm not saying the idea is bad, but its mainly for low boost situations. Not to be used to boost to high numbers. I saw it done to a camero on one of the TV programs last summer (I think on the SPIKE network???)

Looks easy to do, but man it makes me iffy on the whole idea.


Yes, a heat/debris shield would be an easy thing to set up. And yes you can hide the intake tube someplace up away from the water and road poops... But you still may need to extend the wiring and relocate your MAF sensor, the EVAP lines that usually are attached to the intake system... Alot more to it than you think.

Just my 2cents.

Guess my answer stomped all discussion on this topic... Sorry guys.
