I hear good things about STS setups. How does the oiling to the turbo work?

Haha I know right. I actually like the first vid better. That turbo whistle on that Mustang.....my god it sounds ridiculous!!!!

 

just any sound of a V10 viper makes me happy in my pants hahaha

 

Oh....eff that. The Corvette sounds way better in that video. The sound of that turbo spooling > Viper exhaust note.........by far. Hence why the Viper turns off, lol.

 

My buddy has this on an 07 stang single turbo 430 hp and 488 tq it pulls pretty nice

loud turbo.

Im waiting for someone to try to mount their supercharger like this so they can run intercooler piping :-p The STS kits and this proves you can really mount anything anywhere with a little work.

I was thinking this was the case as well.

Lots of charge piping equals lots of time to cool.



I might drop my S/C build for this.


Might...

and u can check out the rest of his vids by just clicking on him username

ok so how much boost can u run on one of these? is it cheaper or more expensive?

 

What???

 

Making big numbers means absolutely nothing if you make them too high in the power band. So, while I don't doubt the numbers that guy made, I'm interested to see the actual dyno chart to see when he sees the power as opposed to how much hp he made.

Those setups break every rule in the book concerning turbos, but some people swear by them.

It would definitely be a cheaper route, that's for sure. I'd like to see some 1/4 times to back them up though.

 

look at the edited post, not that one.

 

I still think the turbo sounds the loudest on that STS Mustang video I posted.

 

yeah, why didnt you look at the forum you posted it it mr smart ass. (just in case you didnt check, its the LNF forum, which means hes already set up to run a turbo up by the engine)

you find one guy who knows jack **** about turbos says that a STS kit will push more power than a top mounted/close to engine kit
and you found one idiot

on a car that already has the space and piping for it, there is no way in hell you would ever need to run a rear mount turbo, their primary function is for cars with little to no room up in front

god your shooting 0/2

what spools a turbo? Heat
What does air do when it travels to the rear of the car? cool down

same car, same turbo farther away will cause slower spool.

or heres another one for you, why does an intercooler have a pressure drop?

because it has a length of pipe and there is always a pressure drop with fluid flow

so congratulations, you dont need an intercooler because you created an inefficient 14 foot one that effectively drops boost much more than necessary




Don't get me wrong, STS kits arent bad, they just are designed for cars that have fitment problems

 

I got an idea twin charge it, zzp did one

im pretty sure that is the air flow of the exhaust that spins it. and the STS turbos dont work like conventional turbos they run smaller diameter turbos to compensate for lag, smaller turbo...easier to spool up. And as far as the pressure drop from the long tubing, so what just turn up the boost controller!

 

True, a smaller exhaust housing would definitely make up for the inefficiency of the setup, but obviously that limits the potential power output of the turbo big time. For a cobalt with inline 4, especially a 2.2, that's not a bad deal considering we're limited because of our internals. I would never recommend an lsj conversion to sts however.

 

air flow is only a minor part of exhaust spooling, other wise we wouldnt drop spark timing right before spooling to increase exhaust heat

small diameter turbos also have a less effective pressure ratio, the bigger the turbo the more efficient, the smaller the less efficient it compresses air.
and no, that is the same as a convential turbo, its just smaller as if you had a smaller engine

and turning up the boost on a boost controller doesnt change the fact your not getting optimum pressure at the manifold

 

why are they putting sts turbos on silverados are you saying they don't have enough room for a turbo under the hood. And also heat isn't the only that makes it spin it also has to exhaust pressure, heat makes it spin a little faster because the molecules are moving faster. Also the colder denser air going back to the engine, which has no less lag than a turbo close to the engine, will make more horsepower. Also plenty of people are putting sts setups on 350z, 4 cyl yotas, v6 mustangs, and also the 2.2 balt on youtube (STS COBALT). Next time read up on what you think you might know about.

 

Twin charge is not an option for me. I don't like the extra strain it puts the engine under.

*Not bashing twin charge setups. I'm sure you guys with them love them. Just saying it's not for me*

 

I meant dyno sheet, wanna see when the turbo kicks in.
The subaru wrx's experience a bit of turbo lag, and their turbo's are located somewhat far from the head. I can only imagine when a turbo is all the way at the back how much lag it would add. Notice there's virtually no 4cyl cars out there with these kits, its only v8's, and it works great for them.

 

its called an intercooling affect, most cars with top mounted turbos have them. oh, and their pressure drops arent that bad either since their designed that way

oh btw have you ever read a book about turbo charging?

cuz here is a little excerpt from MotorBook Workshops Turbocharging Performance handbook

"Most of the exhaust energy to drive a turbine comes from waste heat rather than pressure"

and just to clarify, you did admit that heat does cause the turbo to spool (even though in ignorance you believe its mostly exhaust gas velocity, another technical side note, gas velocity slows down as temperature does) and since think so highly of the pipes intercooling effect on the charge to the intake manifold, therefore with your logic the same must happen on the way from the engine to the turbo. and with the absence of heat the turbo cannot spool as much which i like to call turbo lag, wait... what? no wai guys he just used logic!

I HAVE admitted from my first post that STS turbo kits ARE EASIER than a top mounted turbo, which is why they are so widely available for so many different cars since the engineering to go into them are minimal compared to a top mount turbo

and really, if this is such a great idea, why arent there any OEMS using a rear mount set up?

This is from wikipedia for those you dont like reading books
A turbocharger is a small radial fan pump driven by the energy of the exhaust gases of an engine. A turbocharger consists of a turbine and a compressor on a shared shaft. The turbine section of a turbocharger is a heat engine in itself. It converts the heat energy from the exhaust to power, which then drives the compressor, compressing ambient air and delivering it to the air intake manifold of the engine at higher pressure, resulting in a greater mass of air entering each cylinder. In some instances, compressed air is routed through an intercooler before introduction to the intake manifold. Because a turbocharger is a heat engine, and is converting otherwise wasted exhaust heat to power, it compresses the inlet air to the engine more efficiently than a supercharger.

 

cant you just move the turbo up need the exhaust manfold? The air would be alot hotter up there.

 

instead of moving our turbos back which is a huge waste of time and money BTW this "Afterburner" method of turbocharging should be used in conjunction with our stock turbos IE we could twin turbo the car with this set-up using a 50 or 60 trim turbo in back to feed air into our ko4 usually though it is little turbo into bigger turbo I believe for air flow because you run the risk of destroying the smaller turbo at the velocity and pressure the bigger turbo will force into it. I'm not too sure on that one really don't know anything about twin turbocharging a 4cyl engine as its pretty much pointless and with our fwd disadvantage its even more pointless you should concern yourself more with how to obtain traction passed the 400 hp mark than anything else because a fwd car flooring it with that much power on city streets is not really safe. the track is another thing you have a wall you can crash into if you want.

 

this thread sucks...

STS kits should only be used on V8's, period, end of story! if the LNF already comes turbo'd from the factory and there are already kits out there to turblow the 2.2's and 2.4's who in their right ******* mind would put an assmount turbo on a cobalt? other than to say "yeah well i got an STS kit on my cobalt" followed by my response "yea? well you're a moron! congrats!"
