My turbo died tonight

I'm sure the caked on dirt and mud is better for cooling. going over a speed bump wrong would be great for it aswell.

With the rediculous things people steal off of cars, I'd hate to see my thousand or so dollar investment gone because I'm a moron and put my turbo under my car.

It looks like it is tucked up under there pretty good. You could always build a sheetmetal shroud that hides it even more and protects it from the elements.

and holds the heat...

I still don't think it would be as hot as keeping it under the hood

I love having red hot chunks of metal just inches from my gas tank.

And I really love having my air filter right in the path of my rear wheel's spray zone.

MMMM, and I LOVE driving through snow with super heated peices of cast iron, dragging through freezing snow.

OOOOO, AND I love that it passes RIGHT through my suspension, exposing severe heat to parts that were never meant to be heated (bushings, bearings, etc).

Oh, AND you have exhaust velocity being MUCH slower at the tail end of the exhaust, due to such a large diameter "uppipe". The closer the turbo is to the manifold, the faster the exhaust will enter the turbo.

You are acting like underhood temperatures are superheated. They really aren't. When you are driving, you have a significant amount of moving air flowing through the engine bay.

I think it's funny that they say it stays cooler than a turbo under the hood, but they dont have any two cars where they compared temperatures both being the same model and engine and all taht but with just different setups.

Good point about the wheel spray...build a shroud for that. I have seen plenty of exhaust pipes that are less than an inch from gas tanks with no problems.

Heat sheilds for the return piping....if there is a will....

Exhausts and turbos are quite different in heat characteristics as I found out earlier.

THAWA · Post by **THAWA** » Thu Mar 10, 2005 7:40 am

An exhaust pipe isnt nearly as hot as a turbo.

If you make a shroud you're blocking air flow right? So you're effectively making the turbo hotter and cutting down the life span of it, right? Also you're adding an unwanted aerodynamics effect.

Seriously dude, think about what you are saying, before it comes out.

Sure, it works, but that doesn't mean it's a good idea. Lots of things work, that aren't good ideas.

You have 8 feet + of piping, plus intercooler piping. If you build a shroud for it, you are going to exceed the temperatures the turbo would see under hood.

Last I checked, the Supra in the area making 1001whp, still has his turbo under the hood.

And that 1200whp Grand National, turbo is under the hood.

What about the 11 second Dodge Caravan? Yep. Under hood.

I could go on for days....

Seriously dude....back off. At least I have an imagination. There are people who use them and come up with great ideas that sell and people who settle for the same old shit.... I never settle!

It would be a shroud like they have for under the hood...where the conical filter is awy fronm the heat and elements.

Going through deep puddles is out of the question. Maybe you could cut a hole in your trunk and route the filter pipe through it.....seal of the hole with some hightemp silicone or a rubber grommet.....

I'm just kidding around now. It's a good idea if you want some extra boost but it is not practical for everyday conditions.

THAWA · Post by **THAWA** » Thu Mar 10, 2005 7:48 am

Good idea for extra boost? Why would any of us put this setup on our cars? Why wouldn't you just raise the boost if that's all you wanted?

legacycontinues · Post by **legacycontinues** » Thu Mar 10, 2005 7:50 am

And it stays under the hood because nobody had any better ideas. Woop de doo!!

FG!! · Post by **FG!!** » Thu Mar 10, 2005 7:51 am

That design isn't good. Heat is good for turbos. Turbos run on exhaust pressure and exhaust heat. If you want it to run cooler, turn the turbo down.

The turbo glows brighter because it's at a higher temperature than the surrounding pipes. The pressure decrease on the exhaust side represents an increase of entropy of a non-ideal gas, which equals a rise in temp. I'm sure there's some younger engineers in here who can double check my logic.

legacycontinues · Post by **legacycontinues** » Thu Mar 10, 2005 7:52 am

extra bost for N/A cars.....If you have a turbo under the hood already why mess with it if it works? Turn up the boost. Get a bigger ball bearing turbo..... go for it!

Get creative. The norm is just so damn boring!

THAWA · Post by **THAWA** » Thu Mar 10, 2005 7:53 am

No, it stays under the hood because that's a more effecient way of doing it. Just because something is new doesn't mean it's better.

Wouldn't a pressure decrease equal a drop in temperature?

legacycontinues · Post by **legacycontinues** » Thu Mar 10, 2005 7:53 am

I don;t believe turbos run on exhaust heat.....heat is the enemy.

THAWA · Post by **THAWA** » Thu Mar 10, 2005 7:55 am

I think you missed the point of what I was saying. Instead of doign this custom fabrication and ineffecient design, why wouldnt you just bolt on the parts from a turbo car to an na car and have a design that has had more than 20 years of R&D put into it?

legacycontinues · Post by **legacycontinues** » Thu Mar 10, 2005 7:55 am

I'm not knocking where the turbo is at all...shit I am buying a car with 2 of them under the hood.

I just think the remote mount trubo is a cool little toy for N/A (never made a turbo model) enines. There is no custom manifolds needed. Saves a ton of dough. Granted you won't get the HP of a manifold feed turbo...but I bet there is a good little increase in HP.

JUST A TOY.

BAC5.2 · Post by **BAC5.2** » Thu Mar 10, 2005 7:59 am

Yea, Heat is good. Heat makes things move faster. Higher EGT's mean the exhaust is moving faster, and that means it's moving from the heads to the turbo quickly. Good for spool up. [edit] To high EGT's is when you start melting valves and warping heads. Ever heard of Header Wrap? It's used to insulate the headers, crosspipe, and uppipe, in order to contain heat. Same with a turbo wrap. All used to aid spool time.[/edit]

You want to fit your EJ20TT motor into a USDM wagon, why aren't you just locating the turbos under the gas tank?

THAWA · Post by **THAWA** » Thu Mar 10, 2005 8:05 am

So you're going to spend at least 200 on the exhaust and intake piping, plus the filter and all the accessories you need, when i could pick up an entire engine from intake to downpipe for 200 at a junkyard. How much dough are you saving? Wait I could then part out the engine and actually be paid to turbo a car. And you're saving how much?

legacycontinues · Post by **legacycontinues** » Thu Mar 10, 2005 8:07 am

I am going to get the whole JDM RHD 20TT sent here..... not just the engine.

You have to admitt that heat is bad for everything. I understand how they work but heat is a killer.

I used to think soo too. It's actually quite the opposite for engines.

I know my car runs like shit when it is cold....(cold for FL is like 60)
