I like it. Something different.

I wonder what the volume of your cold side plumbing is. With all that cold underbody airflow there might not be need for an intercooler even at higher boost levels.

In for spool data and IATs.

 

Comp Turbos, water cooled ceramic bearings, no oil. I live in California and it's my fun car. The electrical components are really no concern, there sealed and just fine. If I live where it rained I would have done things differently.

 

intersting.

i still dont like the idea of running wires and electircal components to a remote location instead of just vacuum line. like the map sensor... you shoudl be taking the reading off the intake mainfold, no idea why'd youd put it as far away form that as possible.

 

Dear Braineack, I was hesitant to even post my car on this site because of all the grief and hassle I've seen you give other people because they don't conform to your standards or opinions. I built the first FRS rear turbo car on the planet a few years ago and got a lot of grief then. I know what I have and you can't change that, if you have nothing nice to say why say anything? Some people are interested in the setup and your not so move on or just follow along.

 

The IAT @ 5 PSI was about 125 degrees. I will probably go 8 psi and we'll see what happens. It may need a cooler.

 

It's not the MAP for the intake, It's the MAP for the exhaust pressure.

 

wow, are you going to cry? Is that not a legitimate question? You said you did it for smog and to trick people, but will it trick a cop when he inspects your muffler? does that not happen in CA -- i cant imagine that car being quite...

and I dont just say nice things (that's what your mommy and liberal art tecahers are for) and people shouldn't expect others to hand out compliments. grow some ******* ***** *****. do you need to find a safe zone?

I'm not even giving you grief, just some ****.

 

ah gotcha. What's the purpose of that?

 

Dude, he's just giving you some honest feedback and asking questions that are worth thinking about.
He's not being particularly hard on you... yet.

 

I have learned that this forum is the most "trial by fire" place on the internet. You will get torn up at first, but for those that make it past the grief, it is an amazing place to be at with great insight and knowledge.

 

What was ambient? Temp over ambient is more relevant.

How does the longevity of an water only turbo compare to a oil and water turbo? any plans to switch to an oiled setup down the road?

 

You can use the exhaust back pressure to see how efficient your turbo is working. From what I understand the back pressure should be under your boost pressure or close to it. Don't quote me as I was told that and have not done due diligence yet.

 

Ambient was about 80 degrees. The turbo should go about 100,000 miles. At oil changes you shoot a couple pumps of special grease into the zert by the center cartridge.

I really don't want the oil pump nightmare, the water cooling is pretty clean setup.

 

Man, don't be so sensitive. Awesome build, loved the STS remote mount stuff for the C5. I thought that was always an awesome way to keep temps manageable and with modern turbos you can still get decent spool characteristics out of remote mount stuff. You should post some of your logs and let people pick them apart. Don't let your ego be hurt by it, it's just the internet. Lots of great information in all the skepticism here.

 

I like this because it's different. But like others, I question whether this has any benefits compared to a normal mounting location.

Also, as you already stated that you were aware of, sometimes people offer some "tough love" here. If you knew you were going to get it, then buck up and take it. At least you're not JDM corvette guy.

 

I'd been trying to remember the name of the manufacturer that made the oil-less turbos. I've heard about them once or twice, but no first-hand experience.

The relatively high boost threshold, I suppose, is to be expected given the bearing configuration. I'll be extremely curious to follow the progress of this car and see how it holds up over time.

Welcome aboard. Looks very nice under the hood. I have a special fondness for sleepers.

 

Thank you about the build. I know that everyone takes their lickings here in the beginning and Brain is a sharp guy. When I did the FRS build STS actually called me and wanted to know about the Comp turbo setup so they could eliminate the oil pump setup, although that's what their Patent revolves around. As soon as I get a handle on learning tuning better I'll post some logs.

 

Comp Turbo in California.

 

im really quite dull.

 

You guys are on fire today.
