STS turb install

the guy that spends a month cutting and welding for a proper turbo is going to make more than the remote guys could ever dream of (proper built turbo motors with a REAL block and turbos make over 1000hp in a street setup) the big problem is most factory blocks won't hold too well over 500-600hp TOPS
 
I realize this, and I am not saying this is a good plan for our engines.

But the engine bay of any of our cars is a lot more spacious than some of the modern cars out there... ad turboing one of those becomes a huge project fast.

That's all.

Besides, a LSX with a remote turbo kit will wipe the asphault with whatever turbo kit you can come up with on one of our 6's anyways :)

shoot.....bone stock LS1 and LS6 powered firebirds/camaros are serious contenders.

I beat the time of a 2002 trans am (we didn't race but we compared time slips) he ran a 13.6x all stock on street tires
 
Given the nature of under hood space these days, a simple bolt on like this make sense from a return for time invested point of view.

I am wondering, if you have one mounted in the exhaust, could you use long tube headers to helkp punch up the lower rpms while the turbo is spooling up to help out on top? Hmm.

As for danger from road debris you have a point. Of course you could fabricate a shield to help out to some degree.

I don't think so..... Maybe, if the build includes after market cylinder heads, rocker arms, 200 hp shot of nitrous oxide to help spool it and an alcohol spray kit.

Well, an LS7 would. That's a whole different animal than anything that came in a Camaro/Chicken though.
 
Well, It may not be faster than your car, but you could certainly make more power than your claimed 450 with a STS turboed LS1/6/7.

Comparing a stock street car chassis with a bolt on to a gutted drag car isn't exactly productive.
 
With the low power (relatively) that those produce, lag won't be noticed much on a 300 hp car since there's so much power there anyhow.

It would be noticed on a 200.
 
Remote mounts dont mean it has to be low power, there is a guy with a Vet in Orlando that ran 171mph 1/4 with the STS system. I am yet to see one get damage from water or rocks hitting them. They do mount up higher than the rear end on most of them. Now if you have room under the hood there is not much need for a system like this. Keeping the engine compartment stock would be the only reason I could think of.

Also running headers does help, but you need to wrap them & the exhaust all the way back to the turbo. Plus running the right size pipe with the right A/R on the turbos exhaust makes a big diff. I have heard of these kits going from only making a few pounds of boost to making big boost, just by wraping the exhaust.

As far as the turbos lasting, As long as they have good oiling, they out last one under the hood because they are not run under as much pressure or heat. Oiling can be a problem, but with the right pump its no big deal.

Never heard of the hedders helping, or the wraping of the exhaust? I asssume the exhaust wraping.


Here is what happens, A turbo is driven, not by exhasut flow, but by the differential in heat across the wheel. You will find that any system will drive the turbo better if you keep the exhaust hot before the turbo & cool it after the turbo. It is kinda like creating a vacume across its wheel & pulls the exhaust threw it instead of it being forced threw it.

When you exit the turbo you want to expand the gasses as much as you can ( make the pipe bigger than the turbo outlet) this helps cool the gasses to creat this differential. Also using alunimum piping can help.

Before the turbo you want to keep the gasses tight, do not let them expand, and do anything you can to keep all the heat in there as possible( coatings,wrapings) and keep the piping to a size that doesnt let it expand but still lets it flow with ease.


The fact that a turbo works off a defferintial instead of the flow is why it can work on a remote mount setup. If you understand what is going on and design you system to work with these things then a remote mount system can be very effective. Still there is now way it will equal what a regulor system can do but it will work good. And you can make up for its short comings very easy once you understand how turbos really work.

Hybrid turbos come to mind real fast when I thinjk about remote systems. A hugh compressor side with a very small exhaust side, and all of a sudden you are pumping a high amount of air that is very cool/effeicaint, even cooler than some of the Superchargers give.

Remote turbos do have there place and can give extreme performance. If your racing a class that allows X size turbo, then no its not going to be a good choice. If you are not limited on turbo size then anythink can happen. But if you have a street car that is limited in the engine compartment, or to nice to cut up, and you just want more power in a easy & cheap way, Dont be affraid of remote mount turbos, they can, and do work, very good (when set up right).


Using Headers on a turbo system of any kind is a no brainer, just remember to keep the exhaust tight & hot, but still let it flow.

I was just more interested as to why you say wrap the headers and the exhaust all the way back, and dont mention the use of wrap with regular exhaust minifolds. But I think you were just talking about how headers.
 
You have to wrap the entire exhaust system to contain the heat. Heat is energy. If the exhaust gasses cool off they have less energy to power the turbo therefore it will make less boost

Good piont with that, most of the time a manifold (which is cast iron) holds heat pretty good. Tubing/header can loose heat easy (just look at how long it takes each to cool off after running) the header will be cool very quick & a cast iron manny will take awail. Still yet, it helps a manny to use coatings ( inside & out) wrap seems to want to cause cast iron to crack, so you dont see it being used much. Although it can cause the same problem with headers, some header do, and some dont. But manifold will benifit, just not as much.

Some say a cast iron manny is better than a hedder, but its hard to get a manny that will flow enough. Back pressure greatly effects the power output, and can be the cause of detination & high egts. On a turbo with 800hp capability there could be as much as a 100hp diff between a manny & a hedder, But even though the manny might not make as much HP it would gain quicker spool up. So its all a trade off that depends a lot on what your trying to do. This would not be a consern if, say, you only wanted 10psi of boost and a little extra power(high back pressure). But if you plan to turn up the boost & make max power then it is something to consider.

wow, lot of remote turbo haters here...

im in the process of putting a turbo in the rear of my 94 150, already did it to an astro van i use to own....


the set up is simple, a day of work to have a turbo on your car. worked great on the van.

I know Im going to get some crap for this post, but i swear guys i didnt think it would work all that well at first, but it really does. and if you size the turbo right you really dont have bag lag.... its a strange concept.... but it works...
 
Not really haters, it just doesn't make much sense IMO when you have a ton of room in the engine compartment.

A remote mount is the ONLY way I'd ever think of putting a turbo on a van with a V6 or V8 (if it's a Voyager with a stock turbo, the point is moot). For a truck...I'd probably still go with a front mount.

On a bigger engine, the lag doesn't matter as much. The 4.3 in the van is much more powerful than a 200, and pretty close to a 302.

what exactly would you use to wrap the exaust in?

header or exhaust wrap

as for all the haters, Im going to have to agree with the above, I Think we all agree if theres room (liek on our 6'es) put it up front, theres plenty of room and loads of power to be made, when theres no room for a turbo put er out back. I think most of us like turbos around here so as long as we can use em go for it!
