ok so this is not a claim, is a question.

i saw a kit made using a t4 turbo with the turbo located where the muffler usually sits ...right behind the differential.

this made me wonder exactly how good of a set up this would be due to the serious amount of length the air would have to travel to get to the tbi/tpi/carb.

has anyone seen this kit? i mean in a twisted sense of theory its a half decent design due to you not having to fabricate exhaust manifolds which can be a real PITA...that or shell out 1000 bucks for the manifolds pre made.....either way....the manifolds are *most* of our problems.

this kit is fairly self explanitory....stick the turbo in place of the muffler....taking away the need for turbo adapted manifolds.

like i said...i have NO idea how effective this kit/idea is --not my idea- But in theory...looked half decent..

maybe some of the turbo people here can clarify if this is even worth trying out......if so...im going to try it....if not....no big deal.

like i said...the air delivered from the turbo would have to travel the length of the car to reach the intake point. not sure on the density or pressure of the air WHEN it gets there....seems to me it would take til about 3500 to even begin boosting a SMALL amount.....looked like itd hurt more than help....or boost just enough to comensate the drag and even it out.....send you back to the hp you started with.

 

Try a search. There was a very detailed thread about this a few months ago.

 

any idea on search criteria? if i put in *turbo* 1000 topics will show up heh

 

try STS. I think that isthe name of the company that makes the rear mount kit.

Hi
I personally havent seen one kit yet, but I have seen videos mostly of lt1's with this turbo setup back where the muffler is. The idea of putting the turbo back in the muffler is fantastic, considering that usually F-bodies dont have that much space in the engine room and it seems to be a kit that is easy and fast to install.

My honest opinion is this; The system is claimed to make 6+ psi of boost. In videos I saw with this system it looked like the engine where reaching that boost level in very high rpm's. Just when it seems that the turbo was kicking in it was needed to up-shift. The car's performance seems to have changed slightly only in the high end and maybe some mid range, but no clear signs of a good low end. Dead stop starts look slow and "laggish", no clear signs of burning spinning wheels. If you compare it to a launch of a conventional turbo system mounted on another V8, regardless of turbo kit maker, the car did'nt behave aggresively and with no signs of heavy tire spinning or incontrolable rear ussually seen in turbo V8's.

Other things that concern me about this type of turbo mounting in the long run is the fact that it looks clean the day you install it, I dont want to imagine how is going to look like after a year of use; snow, water, corrosion, dirt, etc... The turbocharger being so low to the ground is an easy target for loose debrie in the pavement and if for some reason the turbocharger breaks, broken oil pressure/return line or an intake pipe is loosen or leaking, the engine is going to inhale all it can get (pray is not water)until you realize that there is a problem. One good thing I liked about where the air filter is located is that it breathes cold air, but what about small rocks exiting the rear wheels at high speeds, mud, sand, etc...? It seems that the kit comes with an offroad type air filter, but offroaders dont have their filters close to the ground anyways, what is the life span of that air filter, how long is going to survive?, a new $40-$60 filter every three months or so?

Another thing that would worry me is the possibility of someone stealing the car or the turbo only. There is no way to keep it "hush hush" the turbo is so visible that is impossible for someone not to notice and I wont even mention the noise it makes when running.

This is a system that works, but my believe is that it can't be compared to the performance a conventional turbo system can provide.

I personally dont like it because I love openning a hood and admire the turbo and all the plumbing. Turbocharging is not only adding lot's of power to your power plant, it is also making it more beautiful and exotic. It gives you a feel of personal satisfaction once you have finished your project and hours are spend just looking at it rather than running the car

 

youtouched on some very good topics there....i believe you could possibly fabricate some sort of *sheild* for the turbo out of sheet metal so it cant be stolen or damadged by rocks and debris. also another thing is that i believe they make a metal slip cover to slide over the air filter that looks simular to that of a home a/c vent ....cept...round of course...

brute power from a stand still is often sought after but hard to control.....maybe this laggish feature could turn out to be a blessing in disguise.....no wheel slip...no uncontrollable spin outs and the need to do massive suspension builds. but it DOES seem as though unless your engine can handle 7 k rpm pulls that it isnt worth the effort. but who knows.....only real way to know is ask someone who runs it....or run it yourself.

IF you or anyone for that matter has access to a welder and pipe bender....nothing fancy....i have a firm belief that thi is a decent do-it-yourself type project that could pan out to costing maybe 500 dollars.....seeing how it deletes the need for manifolds....and that was always the costly part.

perhaps there is another location closer to the engine bay under the car wher ethe turbo can be located?? doubtful but who knows.....if it was mid section under the car it would literally drag on the ground. maybe infront of the rear end as opposed to behind it.

i like the idea regardless....very clever.....IF it provides a decent amount of gains. you get all the advantages of a sleeper...pop the hood...you see no power adder....look at the tail pipes....there is only one....that is just priceless.....can you imagine how loud that sucker would spool up with no muffler lol.

i would pay to see the look on someones face when they hear that whinning comming from the rear end and thinking "this pos gears are about to EXPLODE! right then the turbo kicks in and off you go.

i may just have to try this idea out...i need to research more nd see what type of turbo would work, what type of BOV to use....etc etc. im not a turbo man....but....im always up for learning something new.....

anyone have any ideas as to what turbo to use?? nothing new...i want a used one....what type of car to look for to pull the turbo from...year make and model....size of turbo..... etc etc....
