you may be loosing exhaust speed but look at this. The exhaust gases are cooler at the back of the car, i can lay my hand on my muffler all day and it dont burn, its warm but it dont burn. up in the engine compartment i cant even barely touch the exhaust. High heat is loss of power. Back in the rear of the car w/ the gases cooler that makes the air more dense. Denser air rotates the turbo faster. On 7lbs of boost on a vet they took a base vet from 350 some hp to over 520hp. thats more then a brand new z06. Also there is a video of an instialtion on youtube and streetfire they explain the different between the normal turbo set up and a remote mount set up. the intercooler on a normal set up is rated at 75% efficancy for cooling the air. the same intercooler on an sts remote mount set up is rated at over 97% efficancy. The main reason is because the charging pipes that run back up to the engine compartment act as a secondary intercooler and the air cools as it travels back up to the engine compartment.
Going off of their calcuations for the sts system (which is the set up im going with on my car) 7lbs of boost should put me some where near 270 to 280 whp. I'll be taking the system to about 18 lbs of boost since my engine is built to handle 30lbs of boost and 500bhp. Im looking to hit a goal of 360whp not on nitrous

bwuahahahahahahahahahahah
thats ****** rich kid, 7psi
with that all mighty gt28rs ehh??
at 7lbs you should be happy to make 200whp.
BOOST is not the number your going after here....you need air flow VOLUME to make horsepower.....you have to have enough air and fuel flow/VOLUME to make power....boost is nothing more then a guage of the restriction of that air volume movement through your engine.
i'll tell you what....
you run your 28R at 10psi and I'll run my spec'd 30r at 7psi....lets see who makes more power.

look at the LNF motor... that pushes 260 HP on a teenie turbo... at like 20 PSI !@!!!! .... you can't tell me that you're going to make over that using a SLIGHTLY bigger turbo... at a 1/3 of the psi... be serious man... even a traditional mount system only runs 240 HP on 7psi from hahn and such... you're outside your mind if you think you're gonna make 270 WHP on this STS setup... the turbo has to be tiny to actually spool up efficiently and with turbos you're not losing as much as to heat as you are with something like the heaton... so heat shouldn't be an issue... yes i know i bet some anti traditional fanbois can pump out a ton and a half of videos from you tube or street fire showing turbos glowing red hot or intake or exhaust mani's glowing... but the fact comes down to...
if heat were such a problem every major car company wouldn't be using the setup..
adam... long time no see.. how's the jersey been treating you...

as far as the efficiency: from most of what people have said is that without the heat to create pressure, the turbo won't spool. or just not fast enough. so considering the cold air gains on the engine intake side, there must be a trade off or a correctly sized turbo that could spool up decently fast and put enough cfm of air into the engine to make decent power. there's always a trade off or compromise.
actually the reason i made this post was because i was looking to see what the more experienced turbo guys on this sight had to say about this setup. but i guess i'm a noob for doing that.

i think the STS is really really a bad idea for a DD... if you have your car lowered... you can just kiss your turbo goodbye in certain areas
i don't think people were necessarily flaming you... just the abundance of people offering up their woh fully incorrect knowledge

your getting close but still wrong.
the high EGTs will make the exhasut gas expand at a faster rate thus putting more "pressure" on turbine blades to spool...the long you make the exhaust gas travel the more it cools....its an exponential number, not a linear set.
and as far as your odd--"considering the cold air gains on the engine intake side, there must be a trade off or a correctly sized turbo that could spool up decently fast and put enough cfm of air into the engine to make decent power. there's always a trade off or compromise" statement i think your off your rocker.
no matter how long your intake to the turbo is your still hitting the same hot ass center section and compressor cover.
then if you have LONG intake piping from the rear of the car to the TB you increase lag, once again at an exponential rate....and then lets not forget about pressure drop across that pipe is well....so the cooling effect is offset by some far worse effects...nothing our solid A/W IC cant fix or a normal A/A IC at that.
the STS set ups are good for low boost kits and for motors that are effected more by boost(i.e. high CR V8's)

in conclusion based on what you have said if i were to do this setup over a traditional turbo setup i would be extremely limited as far as increasing power later, and not only that but the gains would be no higher than what i'm running right now on my eaton.

ok so basically due to the fact that you lose so much due to lack of exhaust pressure and heat there could be no feasible set up of this kind for a lsj motor and the only motors that this could make any real gains on are v8 or v6. basically are cars don't flow enough from the cylinder heads to support a setup of this kind?
btw 06black you got any pics of your turbo setup, i plan on using a gt3076rs when i do my kit, i just don't wanna run into issues with clearance.

But that's why I love this site. It's entertainment sometimes.

our engine flows plenty, better then most, but not good either.
engine head flow arnt the issue....the drawbacks of such a long pipe system are the issue, and our little more doesn't help hide those issues.
the STS kits do good at low boost on a big motor because a high a high CR motor with more CID will benefit more from forcing air into it...even at a low PSI and then those kits become almost efficient.....almost.
