Keeping the heat in, getting the turbo as close to the exhaust port as possible to retain velocity scavenging, etc...

No lag, No heat, longer turbo life w/ the setup

 

I don't know about the no lag part. Just look how far the turbo has to push the air to get to the engine.

 

cool, i might get those for my tahoe.

 

It has lag but the fact that it has a v8 eliminates the feeling of lag.

This is actually not the first time I've seen kits like this.. but this is the first commercial attempt at it.

I have read about this a few times, and saw the product about a year ago. I think its pretty clever, and due to the reduced heat, and long runs of intake pipe, the air has the opportunity to cool off after being compressed. I'm not so sure about the "no lag" portion of it, but it will work, no doubt about it.

I think the hardest part is creating an intake system that works well and can be routed (as everyone else would be concerned about) Its interesting that the turbo in some of these installs is used in place of the muffler.

The one thing that is kinda cool about it is the "under hood stealthyness"

I'd be more than willing to try a setup out like this on my malibu but it seems like a majority of cost is in long intake pipe (though any good muffler shop can make a stainless pipe.)

I guess depending on the level of boost, a BOV may not be necessary because of the very long intake tract.

 

Couple problems I see with that setup.

It does not have no lag, thats for sure. Using the piping as a heat exchange unit is somewhat novel but I bet they left an intercooler out for lack of fabrication skills and to keep costs down. No doubt that the lack of fins on the pipe keep surface area for convective heat loss from the pipe at a minimum, severely limiting the amount of boost you can run with that setup. Underhood stealthiness? Highly doubt it; anyone following you in traffic will see the turbo easily, and anyone familiar with an LS1 will note the lack of the ubiquitious induction lid. I work and race on LS1s on a daily basis and can tell you that this kit has had zero success in the LS1 community AFAIK. I like the lack of mandrel bends on the intake tract, the great idea of routing piping UNDER the k-member, having it come within three inches of the hottest part of the exhaust system: the cat....

Malibu: If you consider this setup, stainless steel would be one of the worst material choices for the intake pipe. Go with a high heat rejection material like aluminum.

 

How about hydro-lock from driving through puddles, the air filter is under the car in the back. On a dirt road (I live on one) the filter would be clogged after a couple of miles of driving. It's all too exposed IMO

 

I agree. These guys who make the kit are not engineers. I like how he talks about turbocharging theory and quotes PV=nRT. The dumbass has no idea that the ideal gas law applies for closed systems only, and last time I checked there was an exhaust tip on the car....

 

Yeah that occurred to me after I saw some of the pictures of where this stuff ended up being located..

and I agree with the aluminum pipe, but I suspect that it would get dented or crushed under the car like that..

There's obviously reasons why very few have done this..

I can actually think of the "Theft possibilities" if these things turned up on hondas..

Of course the stealth factor didn't apply to the LS1/LT1 camaros, I've had several and know all too well how easy it is to see.. But I was pondering another vehicle where this thing wouldn't be visible at all.

It also sounds simple enough in principle.. But we'll see what happens, this isn't something new.. I've seen setups like this attempted since the late 80's..

 

The lag would be so bad on that setup that you might as well get rid of the whole damn kit. The exhaust air is so much cooler in the rear that I'd be suprised if it had enough energy left to even spin the turbo for decent boost. That kit has miles of piping for the air to just sit in, I bet the lag on that system is ridiculous.

 

how could there not be lag. you have 20' of intake trackt between the turbo and the engine? besides, a turbo is more efficient when the exhaust gas that spins the turbine is hot! the hotter the better. when it cools you are just wasting thermal energy, throwing away all that beautiful turbo spoolin ability! anytime you put a relatively small single turbo on a V-8 your not going to have any lag, the v-8 makes plenty of toruqe anyway, so you dont notice the lag. its funny though, all of a sudden it makes lots of power, say around 3500rpm but its not lag! hahaha...no thats concidered lag

 

pretty neat idea

 

i am such a newbie.. haha.. no idea on what this is about.. haha
