Remote turbocharger

[crowdog]

For any of you guys interested in turbocharger.There is a company in West Orem , Utah that make remote,as in mounted under the car and away from all those pretty plastic part, turbo systems.They don't currently have a kit for the MM , but maybe with enough inquires they might make one and if its priced like ther current kits its a bargan. How 70% increase in power , full boost below 3000 rpm,8 PSI, and all for Less than $4000.00. Would you please check them out ,Squire Turbo Systems, before you give me to much grief. :flamer:

Pretty sketchy post, do you have a web address?

My buddy just ordered a turbo from this company.
This company is on the rise FAST!
They bolted the turbo where the muffler would be on a stock LT1 Camaro, routed the piping back to the engine (which acts like an intercooler when traveling that far) and went mid 11's.
This is the company you want to do a turbo for you.

You are eZackley right there.

interesting stuff

seems like a bunch of expensive shiat to have hanging under your vehicle..but they are showing off road applications too so they must have thought that through

[merc406]

Zack, let us know how your buddy's car comes out.

I dunno guys. The turbo lag will be long enough for you to write a letter to the engine.

I looked at the chart and it looks like the worst possible configuration for an automatic trans. Without being able to hold it in a higher gear you will have to wait for the rpm to spin up, then the turbo. Picture flooring it out of a curve, then a second later, an extra hundred horsepower jumps in and you lose the car in a spin.

Of course if you are just drag racing you may not care. But, it has to be tricky to drive fast in the real world.

I would guess this would need to be installed before the "H" or "X" pipe in the Marauder... Right?

My guess on the best place to put it would be before the H/X pipe, but you may need to remove the crossover, so that exhaust pressure stays high on the turbo and you can still mount it far back.

Also, I don't see turbo lag being a big deal. The simple fix would be putting in a higher stall convertor, which I would think you would want to at least replace anyway so as to put one of the stronger PI Stallion convertors in to handle the extra horsepower.

I'm waiting for a callback from them to discuss possibilities for my MM. I don't have any problem getting a "basic" kit from them, and just do the custom piping with a friend of mine at his exhaust shop. I had actually thought about this idea when I bought my first MM, but didn't feel comfortable with the technology & mathmatics behind it. I'm glad to see that someone may have a lot of this figured out and can help me with a possible starting point.

I love the idea of a supercharger, and am pretty close to getting one, but the thought of having something "different" is really cool!

Hmmm, I'm watching this thread, since I think I may be about to learn some things about turbo charging with the give and take that I suspect will be going on here.

Different is cool but there may be good reasons nobody has done this before. It would be a great idea for an aircraft engine or other applications where there are not a not a lot of throttle changes.

Back when I had hair I owned a Porsche 911. A buddy had a Porsche Turbo. I could drive smoother and faster in my car on anything but the straightest roads. The turbo lag in his car would show up at the most treacherous times. Once, he floored it at the apex of an increasing radius turn. Partway through the turn the turbo kicked in and he spun off the road. I had a great view from behind him. It was spectacular!

I don't even like centrivigal superchargers because the boost builds up late and the boost curve is so steep. The fix, overboosting and adding a waste gate, causes a lot of parasitic drag. The Roots type, the Eaton for example, acts more like a pump. This means that more air is moved at lower speeds.

If you want to shorten the turbo plumbing by mounting the turbo under the floor you will want to add a boatload of insulation. Other wise the floor will heat up, making the car uncomfortable at best and deadly at worst. I screwed up once and used short steel brackets to mount the exhaust system on my old Falcon. The floor got so hot that I ccouldn't drive it.
:fire:
As always, your mileage may vary.

I have owned turbo and s/c oem vehicles. The Porsche Turbo was at it's introduction one of the few production car turbos out there and it was notorious for turbo lag.

The turbo and s/c oem vehciles I owned did not have any lag. I think the technology has come a long was in teh past 20 years.

I checked out the web site and their technique addressed all the heat related turbo concerns I have and have previously discussed in this forum.

From a previous post;
"I have owned OEM Turbo and OEM S/C.

The prob I had w/ the turbo is the retained heat under the engine compartment. All non-metal parts literally fry, I mean every thing, belts, wiper fluid container, electronics, every thing!

IMHO turbo cuts these under hood components life by 70%.

An S/C does not affect the life of these components.

Also w/ a turbo numerous internal engine parts run hotter simple because the turbo is a big heat sink and you are restricking the exhaust/heat escaping."

[Macon Marauder]

Yah, I too think turbos have come a long way. I have an '87 TBird turbo and it has just a touch of turbo lag. When the turbo comes on it feels and sounds like the secondaries on a 4-barrell carb.

They're probably even much better today.

[dwasson]

But the primary cause of turbo lag isn't the turbo (except the mass of the rotor) as much as it is the length of the plumbing. The longer the distance from the engine to the turbo (and back), the more turbo lag is inherent in the design. Modern turbos have less lag because the manufacturers have new materials that allow tighter installations.

[ap2003]

Turbo's work like superchargers... in the sense that both devices pressurize the air coming into the engine... So the distance... and volume of the transmission line between the air pump (turbo) and the engine intake is probably a significant part of the system response...

Volume of air that is pumped by the turbos is a function of the impeller is a function of the area/speed/angle/etc....

Since there is more volume to fill in the path between the turbo and the intake... it sounds like the most logical solution would be TWIN turbos.. more volume... quicker...???? :) !!!

But there is always that cost issue that creeps in to the equation... :(

Also, I took a look at the installation on the website... It sure looked like the turbo would be pretty close to the speed bumps..?? Am I looking at this right?

This is true.

STS's idea is nothing new. Others have tried it and have failed in automotive applications. Lag will be an issue with the compressor so far removed from the origination of exhaust gases. Because a turbo relies heavily on the cooling of exhaust gasses (and the resultant expansion of the gasses) to drive the impeller, serious inefficiencies (and lag) result when the turbo is place too far from the head.

The only solution is to use a very small compressor and limit max PSI. However, the turbo is overspinning on the top end of the rpm band.

This is turbo 101. There are reasons why others have not done this.

[sailsmen]

I think you can generate 6psi very easily w/ the remote turbo and the right turbo application w/ no lag.

Keep in mind w/ 6psi there is no intercooler, just the longer pipe, whcih may have less pressure drop then the intercooler.

[MikesMerc]

It's not about the boost side. It's about the inefficiency of the compressor being too far from the hottest exhaust gasses.

I'll see if I can dig up some linkage re: remote turbos from the past....

[sailsmen]

Wouldn't the pressure be the same assuming no loss of pressure thru the pipe or pipe joints.
