I just got to thinking...


I've read a couple of articles on s/c mark 8's.. and I know theyre a bitch to fit on the motor..

But, what about STS remote turbos?

I've searched around on the forums and I can't find anything on them..

If I got ahold of a decent exhaust shop and got them to custom fab the piping, couldn't I use a universal mount STS remote system under the car somewhere? I mean.. anything can be done with enough money, but I'm trying to compare this idea to the pain-in-the-ass install of a supercharger..

And I'd rather people couldn't see it in my engine bay. :D


So whaddiya you guys think???

Reasonable idea??
 
I saw an install of an STS system on a C6 Corvette on Horsepower TV a few weeks back and to be honest it didn't look like that bad of a job. As far as a universal kit on a Mark, I don't know. I'm sure it could be done.
 
The STS "universal" kit is overpriced... you'd be better off making everything from scratch really.
 
I've always felt they would be a good match to a stock engine. The biggest issue would be the piping - esp. the return air from the turbo(s) to the intake.
 
isn't there a problem with the turbo spooling up considering how far it is for the headers?
 
no, the housings are different sizes to make up for it. I believe there are a few LS1's in the 10s with the setup on stock internals.
 
its a system designed to add forced induction to an engine that already makes a good deal of power on it own. Its not a purpose build turbo motor but a "bolt-on" for stock to mildly build engines. The long piping means the spool is slower and the manifold pressure is even slower coming up than a turbo up front but the charge temperature is down due to the passive intercooling effect of that long length of tubing that is exposed to the cars slipstream. It works well at what it does, but I do not call it a well designed turbo system, just an clever low boost implementation of forced induction for motors that make enough power by themselfs looking for some top end reinforcement to the curves. It will work theoretically on any car that has enough underside room for 4 pipes, 2 turbos, extra oil lines with scavenge pumps, and mufflers. I think the unboosted DOHC motors are perfect canidates for this system since they have the airflow capacity but not the ability to get it into the motor, just don't go hog wild with the boost and the motor should hold together well. Watch your IAT timing retard curve well and have enough injector and it should work out well.
 
I was only planning on using one turbo.. and I didn't plan to get any higher than 8 or so lbs.

I'm just looking for a way to keep my sleeper image, ya know?

I wanna get into the low 14-high 13 range.. but I'd also like to do something that isn't overdone. That's part of the reason I bought my mark in the first place.

I'm gonna start talking to a shop down here in texas to see what they think of the idea. Alot of the ricekiller.com guys have used them and like 'em.. It won't be done anytime soon.. but i'm trying to plan out and save accordingly.

And I've seen firsthand what these things can do to an LS1/LS2.. it's insane.

I'm not expecting that kind of result with a mod4.6.. but I don't think I'll be disappointed at all.
 
Well heck if you're just looking for high 13s you can get there naturally aspirated pretty easily.. With 8 psi you're more towards the 12s range.
 
this oil return line cracks me up

stupid design.

I stongly agree! What a bunch of piping and other junk under your car to run a turbo that hangs off under your back bumper that anyone can easily take!

I'm sure that a single turbo set up could be installed under the hood, It just takes the right tools, knowhow and time. It can't be any more difficult than that insane t-bird set up! Why twins anyhow? all you need is a single. Look at the stang crowd or even the supras, those twins get tossed for a single most of the time.

That remote mount back bumper stuff is a poor design and way too much $$$$, just my oppinion.
 
I am looking forward to someone doing this Mod on a Mark Vlll so we can see another approach that can be used on our cars. Having a plumbers license will definitely help.
 
I just love how that TBird guy bolted the charge air pipe to the exhaust. That must do wonders for the intake temps.

It's being done as we type this. Alex (frogman) has one helluva setup in mind. (think 750+HP.)

I'd love to see it when it's done. This could open up a whole new world for the Mark VIII scene that is tired of the undersized centrifugal blowers.

Tbid guy didn't bolt nothing. The system was adapted to the mn-12 directly by STS people at their shop.

maybe you didnt look at the pics? the charge pipe is bolted to the exhaust at one point to keep it secure. personally i dont think it will transfer uch heat but the radiant heat from the exhaust pipe will.


i looked at the pics again. im sick to my stomach now.
 
So let me get this right, an old-fashion exhaust powered turbo mounted at the car's butt? Ok. I like the leaf-blower idea better.
