it cant be much more Piping than a Twin set up can it..............

Wonder if they will come out with a Twin SET UP....NOW THAT WOULD BE SICK

 

Yes it would have much more. Twin turbo setups have very little piping. I don't know why you'd want a remote mount TT setup when you could just have a normal one.

 

My main concern would be driving in the rain and having a large puddle hit the turbo ......As far as turbo lag I don't beleve your looking at that big of a diff. maybe 2-5 tenths of a second diff...It is exhaust pipes and the car is running so air is being forced...I really comes down to the Turbo itself and how eff. its running to get the best or in this case the least amount to lag....I guess the true test is seeing 1st the placement of the turbo vs. the elements. 2nd the type of turbo assuming that they WILL be running some kind of hybrid. 3rd the #'s and componits used to make the #'s...The old saying the proof is in the pudding

 

That's why I used the phrase "pretty similar" instead of "exactly the same." Also most of those rear mount turbos don't typically utilize intercoolers in their basic kits if I recall correctly, regardless, my statement was based upon the assumption that no FMIC would be involved. I'm going to stick with my "pretty similar" prediction (if the thing ever gets released lol.)

By the way, most turbos like running at higher pressure ratios than the piddly 5-10psi that most Z kits are throwing at them, so "working the turbo harder" might not be a bad thing - one would have to look at the map of the specific turbo though to know for sure.

 

If it wasn't in its efficiency range at these boost levels it wouldn't be a properly sized turbo for the application.

 

ya I hear what ur saying, but i have seen some of these kits have the air filter less than a 6" from the ground, what if its raining crazy hard and you hit a pubble and it sucks up water, Or you hit something and the fliter comes off and you suck up a cat!!

 

I assume most of you have seen this on Speed Channel / Horsepower TV regarding STS Turbo and install on a C6:

You'd have to run a smaller turbine then either of the ST kits for sure. The increased piping length AFTER the cats would kill a lot of the kinetic energy and the turbine would have to be of a smaller type with a smaller A/R to spool up at any form of a decent time. Of course with the smaller turbine and A/R the back pressure would quickly increase at higher boost and power outputs meaning you would be severly limited as far as increasing power output. Hell a Stage V turbine with a .77 A/R which is rather large as T3 turbines and A/Rs go (for a single turbo on a 3.5L V6) starts having back pressure issues and flow issues at 15 PSI and up. Running anything smaller is going to be even worse...running that size or larger is going make lag even worse... Anyone else notice that all the twin kits for the car mount the turbom pre-cat and the singles eliminate the cats completely. Theres a reason for this...

 

Sign me up for a rear mount turbo kit which uses tons of piping and leaves the turbo out in the open for anyone to steal off the car. AWESOME

 

You size them by going one size smaller on the exhaust and one size larger on the compressor. I have researched this topic for a couple of years for prof of why it will not work. It will and does work fine. Sure you going to have a little more lag. Its used on airplanes all the time, and if it works on an airplane engine im sure it will work on a car engine.

 

 

And then you ride the surge limit the whole time.... I guess since Boeing uses Rolls Royce Turbo Fans on their planes i should try strapping one to my car too

 

That would be f-ing sweet!!!!

 

If it works on other cars, why doubt it won't work on the Z? I do notice though, that it makes power similar to superchargers. However, everyone i've talked to who have experience with STS say its not that bad, and it barely lags.

 

Yeah it would. Or I could pull the urban myth of the guy who strapped a C130 Rockect Assist Pack to my car. TEH UBER ULTAMIT NAWZZZ YOOOO...

 

rear mounted turbos were used in WW II era aircraft like the Republic P 47 http://rwebs.net/avhistory/history/p-47.htm (note that the turbo is located 22 feet from the 18 cyl radial) and the Lockheed P-38 Lightning http://www.compsoc.man.ac.uk/~wingma...p-38j_022.html (note those things in the engine booms towards the rear of the main wing section). Beacoup hp, throttle response - I dunno. I don't know how much throttle response mattered in aerial dogfighting of that era...

 

I'm not going to get into the debate on how well this will work. Better to wait and see numbers when (if) its released...

But arguing that having the turbo rear mounted under the car makes it likely that someone will steal it, is absurd. Lots of people on here with FI have carbon fiber hoods, which would take all of 30 seconds to smash open around the latch and lift. If you think its easy to pull a turbo off under a lowered Z without making a huge production of it (did you bring your jack and stands, mr. turbo thief? how about a shop light, unless you plan on doing this in broad daylight. Be sure to bring a buddy to hand you wrenches and sockets while you're under the car, unless you're bringing a creeper also to make it easier on your back), then you need to come help me work on my car sometime cause you are truly a wizard.

If your turbo kit gets stolen, anywhere you need to spend less on your car and more on relocating your *** out of the ghetto.

Retarded argument

 

Most people dont run cats with turbo anyways, so that's not a big problem. And it's not that much lower than a APS Single Turbo, so the chance of damaging the turbo is not that much higher either. But most of the current STS kits doesn't have an intercooler, with the Z's high compression, this is bad. If they do use an intercooler, they might need to use a bigger turbo, which increases the lag. And the turbo need an oil pump, so it'll have the same complication as the APS ST.

 

thank you!!!!!!

 

There have been a number of verified incidents of STS turbos being stolen off the rear of the car. If I didn't have to leave right now I'd search for some stories. All I'm saying is it's just one more thing to attract attention from thieves to your car. And it's a lot easier to steal than your example of a CF hood. You'd have to most likely DESTROY the hood to get it open and what good is it after it's damaged?
