I posted this on another post as well, but I think it needs it's own thread.
Like I said in the other post This is not a done deal yet, But I work closely with the manufacturer and can help push it through if the interest is there.




The company I am with is the Utah Dealer for Squires Turbo Systems. www.ststurbo.com (http://www.ststurbo.com/)
(STS headquarters is about 20 Minn from our location)
I had my truck over at the offices last week, and had a VERY interesting conversation with the head of R&D.
He told me that they are interested developing a, "Remote mounted Second Stage Turbo for the Duramax".

I don't know much more than that at this point. However I have no doubt if it ends up being produced it will be very well done. The systems they currently produce for the Gasoline engines are amazing!
My guess is if they have enough interest from the Duramax community I believe they will invest the R&D dollars into the project.

If anyone is interested in seeing this developed, Send me an E-Mail and I will get it into the right hands...

It's a neat concept. There are already some putting a second turbo under the hood. If I was going to do it, mine would be under the hood. I don't like the idea of it under the truck like that.

One reason I like the concept is ease of installation and removal.
I have yet to see an under hood twin turbo setup. However it would almost certainly require allot of effort and fabrication to make everything fit.

Conceder if the 2nd stage turbo was positioned just after the down pipe, just ahead of where the LLY cat is now. The "Cat pipe" could be easily replaced with the "turbo pipe".
Modifications under the hood would be virtually eliminated. (It is not like we have allot of room under there to begin with.)
The plumbing would be simple and easily removed, and returned to stock if needed.

Typical install time on the current 1500 and 2500 HD gasoline truck kits take less than 4 hours to complete by just about anyone who knows there way around a set of tools.
Removal takes less than an hour.

As far as length of the oil lines to feed the turbo. It is really a non issue if the turbo was just behind the stock one. And unlike many superchargers you would not have to punch a hole in the oil pan, or make really any modifications that couldn't be easily reversed.

I have yet to see an under hood twin turbo setup.

i think you have a better chance of seeing bigfoot on film than those twins.

check this site for a pic of twins www.quicktimeautomotive.com

That picture alone makes my point exactly.
Who but the most hard core racer would ever go to that much work to do an under hood system.

Compared to that, the STS Twin turbo system with the 2nd turbo at the bottom of the down pipe would be much easier to install or remove if needed.
The fact that there would likely be almost no modification under the hood would be the bonus.

I've been reading about this setup in Camaros/ Firebirds and GTOs for a couple of years now and wondered right away why not for the Duramax? Just do not limit your scope to the LLY. There are way more of us LB7s out here since we've been in production so much longer. I guess as long as it was generic to both then you've reduced your overhead, cheaper to build. Yada, yada, yada. I'm all for it. Git 'er done.

What I would like to see is a system that is so easy to install that the stock airbox (in its factory location) could be used. Then the intake charge could be routed down to the "Pre turbo" (just below the down pipe). Then the "pre boosted" charge routed up and into the stock Turbo. Everything from that point left stock. (Just one idea)

Maybe the kit could have an Optional upgraded Intercooler, Or methanol injection above a predetermened boost level.

Another advantage is if it ever needed to be removed it would likely be really simple to do. Just reinstall the factory air duct and "Cat pipe", then remove the rest.

I am pretty sure that the system could be developed for the LB7 and the LLY with minimal changes if any. Even if each used a different "Pre turbo" the airflow needs of each motor could be designed into the kits.

Ease of install/ removal is a big plus. I was also thinking that the particular tuning needs between the LB7 and LLY's could be assigned to a add-on programmer. And of course, Edge is also in Utah and nearby. Therein lies a new product line for both companies... win/win for us all.
