Remote Installed Turbo

[1.8Tee]

هو فى شكمان تيربو, أنا معرفش التسمية الصحيحة بالعربى....rear mounted turbo .بس طبعا صاحب الموضوع مش قصدة علية :) :

it is called remote installed turbo

Either of them....won't differ :)l

But to be more precise, rear mounted fits better with what I mean because there are really strange locations for turbo setups

The pic you posted above is for the STS turbo system....isn't it?l

[MMamdouh]

i have no idea... i just found the pic on the internet... honstly i hate such setups and i am sure the guy that came up with such design was retarded or so

Tell me more.....I wanted to know your opinion on such setups but was afraid of hijacking the thread with another content

Anyway from what i've read they are cool setups with nice features but they suffer from the stereotypical image of turbo lag and stuff

[MMamdouh]

well i hate them alot

just think of the amount of tubing you have to do for charge pipes & oil feed lines & oil return lines & coolant lines... i even found more concerns such as water splashes and exhaust gases temp and exhaust turbine rotation speed

also you gotta do heat protect the turbo area and istalling the turbo is a nightmare

i wonder what is the point of such setup anyways... seems too much of a hussle with very little gains if any

First thanks for creating this thread :)l

To answer your questions, there are no intercooler/ piping as .the length of the piping running back to the throttle body is enough to cool the air usually. Only a must in my opinion if your running a decent amount of boost

Due to this intake temperatures remain lower, engine compartment temps are lower, and therefore it is easier on the engine

As for the water splashes you can overcome them by splash guards

The point that they are good for cars with tight / cramped engine bays....think V8's. It's relatively easy to install as you don't need manifold to buy/fabricate and an intercooler as I mentioned earlier

About the gains, I'll let you check the link and you judge yourself

Click testimonials there are tons of cars running these things

All in all it's a pretty solid setup for what they are and for the people of the above mentioned criteria but nothing too brilliant compared to traditional setup's(with roomier engine bays)

I almost forgot....they sound great too

it is still argued that the long piping will put lag to the system and even that 350 got an intercooler so thats extra lag... forget about comments saying "hardly any lag" and so, they are talking about an auto tranny car and those don't drop as much RPMs as the manual tranny cars and thus they are not as much laggers as the manuals... also a real racer will be too low to the ground to have much space to put the turbo

and for me i'd charge cutomers double the fees for such setup as it is much much harder to install... not to mention therouting of all turbo inputs (oil and coolant) as well as requiring a return pump for the oil

as for the sound... it is not much different than a properly turboed car... you can clearly hear the BOV as it is under the car not in the engine bay... and for sure you ill hear the turbo so clearly... it is mounted in thin air for crying out loud... if the only purpose of adding a turbo is to hear it then people should record a sound trak and play it over and over on their MP3 player... it is much cheaper and safer... not as much fun though

actually that reminded me of another problem... if you decided to use a bypass valve then you will have one more extra long vacuum line to route and if you go with a BOV then you are reducing effecency even more

also cars with air mass meters will need relocation of the sensor and again long @$$ wiring

it is too much of a hussle to do

Sorry for the late reply

I want to clear a thing that I support this as long as the engine bays are difficult for the traditional setups but as for the 350z....I really find it absurd as there are other traditional kits which are cost and performance effective rather than rear mounted one's

About lag ....You don't really notice it on big V8's, plenty of engine displacement to move a lot of air though the long pipes. Also The turbos are set up quite a bit differently from a traditional setup and it all but eliminates lag. Spool-up time is quick and they (STS) try to compensate for the distance by reducing the diameter of the piping, thus increasing the response time

Isn't the bypass valve just a flapper that remains closed unless the filter starts to suck up something heavier than air?l

[MMamdouh]

well... i was more focused on traditional 4 bangers and those got no space issues... at least not like the V8s

i wasn't reffering to that by pass valve... that is used on cars with CAI to avoid hydrolock in case you drove into a puddle or so... i was reffering to the bypass valve on a turbo setup... it is similar to the BOV but the main difference is that it dumps air into the turbo tubing rather than into air

this gives more system effecency as you use all the compressed air rather than dumping it into the atmospher and also it reduces lag a bit as the compressed air is fed to the turbo turbine and thus allowing it to keep its speed a bit longer and that gives the turbo beter responce time when the driver steps on the throttle once again



only point to take into considiration is that if you are using a bypass va;ve on an engine with a MAF or air mass meter then the return point of the air should be past the air mass meter or else the air mass will "count" the same amount of air twice and the engine managment will be disrupted

I'm so sorry again for my late reply, my internet connection was down for almost a week and I was browsing the forum only through the mobile or briefly during the work

I'm glad you got my point and the objective of those systems. It was really a pleasure having a conversation with a guy of such forced induction background like you. Thanks :)l

[MMamdouh]

thats the beauty of conversations of that sort

i know the advantage of such setup but my personal liking doesn't lean towards them... i wouldn't go for such setup unless it is extreamly necessary... and would charge double my feed :)
