educate me on turbo compressor models

[alwayz_yummy]

ask ko lang, since nag-parang top-overhaul na ako sa 2C-tubo ng liteace ko, sinilip ko ung compressor ng turbo, nakasulat ay T12.

ask ko po specs ng T12 compressor kung may nakakaalam..kung papalitan ko ng bigger compressor(kung lalagyan ko ng intercooler sa susunod) anung model ang pwede kong i-bolt-on swap sa T12 compressor??

for reference lang din po.

thanx!

Here's what i found i think they're made by Garrett Turbo Inc.

T12 Turbo

thanx...its a good start.....hope more will come in..

Higher compression = Higher temperature

therefore mag ooverheat ka

kidding aside.

Kailangan kaya paikutin ng exhaust pressure yung compressor para mapaikot niya yung turbine. I think they have calculated it according to the specs of your engine. Kung naka supercharger ka belt or chain na ang driving force so ibang calculations na iyon.

wala po akong alam tungkol sa mga models, but I think bigger Turbo is not the solution.

"Using a small turbocharger will give quick response and low lag at low to mid RPMs, but can choke the engine on the exhaust side and generate huge amounts of pumping-related heat on the intake side as RPMs rise. A large turbocharger will be very efficient at high RPMs, but is not a realistic application for a street driven automobile." - wiki

"Best way to understand is imagine a little desk fan on high speed vs. a Big floor fan on low. Problem is if you are using a floor fan it takes time to get it up to speed. Big turbo means big peak power but may sacrafice drivability and responsiveness." -evolutionm.net

Turbo is driven by your exhaust, if your turbo is bigger, you need to rev it higher to get more pressure from the exhaust...

that's why some racing cars use two small turbos (twin turbos)...

the solution is to add pressure in your existing turbo...

but check your turbo's condition first, baka it needs shafting...

there is a particular max psi on 2c-t. but I forgot, I'll look it up soon...

nacurious lang ako sa model ng turbo compressor na nakalagay,e... T12, parang di common, like tb04,etc...

If you want good power, use twin turbos. But use a smaller turbo to minimize turbo lag of the larger turbo. The smaller turbo will spin faster, hence less lag than the larger one. Once it spools up, it occupies the turbo lag at low speeds, and then the large turbo kicks in and you can get linear power, unlike what you get now na biglang sisipa yung turbo.

The specs of the T12 given are mostly dimensions, torque specs when rebuilding one, clearances, tolerances, etc. You cannot say it will add so and so HP because that depends on the engine set up you have.

On my car I have a Garrett turbo rin but I don't know yet the name (w123 300D turbodiesel Mercedes). The wastegate is adjustable so you can adjust the maximum boost pressure before it releases it. That is one thing you should know about yours para ma-maximize mo yung potential ng turbo mo.

Here are some good reads on turbocharger wastegate adjustment on the Garrett models if yours is similar (or identical)...

eto some shots ng turbo na nakakabit, share ko lang.. gusto lang din kasi malaman ung rated output psi nito, at kung small/"at-par"/big compared sa other common turbos...





is this the EGR/actuator?



ganito original kabit nyan when looking at the back-side ng engine:

(top pic is located on the left, turbo on the right)

[mbeige]

You can hook up a vacuum/pressure gauge to the turbocharger by looking for an output nipple somewhere on the intake manifold. This usually has a sensor that goes to the ECU or to a device that limits boost pressure para hindi sumobra. I'm not familiar with your plumbing set up but on the last pic it looks like the EGR is on the left, the intake manifold is the tube above going across, and the EGR tube from the exhaust goes to the back of the engine to the exhaust manifold. Like you said the turbo is on the right where the exhaust is, which sounds about right.

plumbing ng air-intake nito ganito->

air filter->(plastic piping infront of the big steel one you see in the pic)->turbo-(ung big steel piping you see in the picture) and <ung small steel piping leading to the EGR(show in the 2nd to the last pic)>

hanapin ko po yung sinasabi po nyu, gusto ko pakabitan din kasi boost guage,e... pero havent heard any "hiss/pssst" when boosting,e....
