Remote mount turbo

Le Mo de Ho · #1 (**permalink**) 10-15-2004, 10:04 PM

After seeing an article in car-craft magazine, I've been researching the concept of remote mount turbocharging and I have to say the more I read about it the more I like it. Here is what it looks like on an f-body http://ststurbo.com/inc/iview/461?idx=5&p=1581 check out www.ststurbo.com and read it ALL. There are pics, perf. #'s, and videos of all the vehicles they currently have kits for.

One thing they mentioned is that they use some kind of special turbo and claim that it is designed to run in the rear of a vehicle and would perform poorly if mounted in the front, just as a conventional front mount would perform poorly if mounted in the rear. What could be done to these turbo's (Garrett) in order to make it suitable for rear placement? Is that just a crock of sh!t and any turbo would work?

It would be incredibly easy to build one of these kits for our cars, the only thing stopping me from doing it is sourcing the "special" turbo.

all i can say, thats gonna be really REALLY expensive the first time you bottom out

yah, or hit a puddle!

I sure hope they don't plan to end the turbo intake there.

Would that not cause some boost lag problems?

read the info in the linked site, it answers all of these questions

i read most of the info, but if you bottom out still, the turbo is gonna get messed up, and especially with how low most bimmers ride, they dont ride as high as the avg domestic car

doesn't seem very practical especially with the intake down there.

"Ground clearance hasn't been a problem as all of the kit sits higher than the stock equipment. The lowest areas are near the wheels which give it added clearance going over bumps. We've installed the system on several lowered LS1s with no problems."

Copied directly from website.

Also for the other two questions:

"With the turbo so far back, don't you get a lot of turbo lag?
No, our turbochargers are sized to operate at this remote location. Just like any turbocharger, once the turbo is up to temperature and in the rpm range for which it was designed to operate. The boost comes on hard and fast. All of our systems will produce full boost below 3000 rpm.
If you were to take a conventional turbo and place it at the rear, you would have lots of lag and consequently, our turbo wouldn't work properly if mounted up front."

"Doesn't water get into your engine with the filter mounted down low?
No, even under very wet conditions the filter sheds most all water. Every kit includes a K&N PreCharger which is a "sock" that protects the filter under very dusty or wet conditions. The only thing you don't want to do is completely submerge the filter. This would draw water through the filter and into the intake tubing. For most vehicles that would mean you would have water coming in your doors before you'd have a problem with the turbo's air filter."

Dado, what problems do you see with the intake being low in the back?
I think as long as your not doing any off roading (which I don't think anyone does with a bimmer

) it would be fine. I have a Buick Grand National and my air filter mounts low to the ground and I have never had a problem. Just my opinion.

Yop, how in the hell did you end up with over 2 billion posts? Been on this board for like 50 years?

is your intake in the front of the car or right behind the tire receiving all the water splash?

It's right in front of the left front tire. Still gets spray from the tire, but the filter faces straight down so the water just runs right off. Even if it does ingest a minute amount of water, it should not hurt anything as I used to run a water injection kit with no problems.

I would like to know more about where I can buy one of these "special" turbos.
I plan on doing a little engine swap in my mini and adding a turbo and this would be an awesome solution for it, the engine bay is so damn small but if I could mount the turbo in the back, even in the trunk with a scoop out the side for the intake and cooling that would be awesome!

The only thing special about the turbo is the sizing of the exhaust turbine and compressor. That is the only thing possible. I beleive it is just a regular turbo with a more efficient exhaust turbine to compensate for the lack of pressure and heat that far back in the exhaust.
Anyone else have any other possible ideas?

BTW, GodSpd, where in GE are you?
