2. Read up on how pressure differential across the turbine affects boost threshold and power production. (Hint: It has everything to do with both). 3. As for oil burning due to lack of pressure. I can see that being an outside possibility, but frankly if there is so much pressure in the exhaust that it is keeping back the oil AT IDLE, then you have a serious fucking problem. 4. The theory that wastegates rely on exhaust backpressure to control boost is somewhat founded, but incorrectly interpreted. Yes, having higher backpressure will make a smaller wastegate better able to control boost, and once you free up the exhaust you will encounter spikes and creep. But as EVERY SINGLE FUCKING PERSON in this thread has pointed out, the issue is resolved by simply RUNNING AN ADEQUATELY SIZED WASTEGATE. The sad truth of the matter is that cars, no matter how well they were originally engineered, tend to be finalized by accountants. Internal wastegates are a. more economical to package, b. cheaper to produce than full on external setups and c. adequate for stock power levels most of the time. The holes are just too small to control boost in a performance setting. It seems to me that the author of that article is essentially stating that a stock piece of equipment should be perfectly adequate to handle increased power output without issue. This is bullshit. If that were the case, all turbocharged cars should come with 2600+lb pressure plates (or twin discs) forged cranks, rods, oil pump gears, and pistons. Heavy as fuck, shotpeened, cryotreated gears and 9" differentials. But they don't. |
running 3" catless system on the mazdaspeed 3 greatly increases your chances of smoking at idle due to oil leaking from seals (i did but found ways to fix/hide it)...but that is because of the shitty turbo. guys who slap on a garrett turbo never have that issue.

Is this the dose pipe guy?

There is an extraordinary amount of misinformation on the web about turbocharging and engine performance in general. Misinformation is not allowed on this forum, so if everybody is telling you that the shit you read on jdmsrt4forum.org is wrong, just accept it until you actually understand what youre talking about (its clear at this time that youre still learning) |
yep its me the dose guy that was something i found on youtube not something i nor many associates practice!
yep iam learning and still researching hey i helped someone clock their turbo on the next thread down so i must be storing what iam learning. the more i read into turboing my car the more expensive its getting what with external wastegates :( |
at least you understand that to do it correctly you're going to want to invest in good/expensive parts.

So your saying this boost creep I had was cause by my massive 2.5" exhaust and muffler? not the tiny wategate? :giggle:

I have had a 3" exhaust on my turbo car for like 40,000 miles or so and my car dont smoke at alllllll. ask braineack. he can vouch.
edit: also my large wastegate means I never boost spike. I sealed up the lame internal gate and put on a tial external. |

Then get a small chinese T3 on ebay and an ebay (XSpower) EWG, replace the spring in the WG with a Tial spring and now you have a good wastegate on the cheap. Then just figure out a downpipe and a dump tube for the WG (dump tubes are hella cool) |
Lulz @ thread title change...

although once again the turbo Gods have released their ingenious wisdom to counter the force of the former NOS-slapping-sticker queers,
can i just say THREAD FAIL. |
I don't feel like going back to the first page to check, but has no one pointed this guy toward the FAQ or suggested he read up on how turbocharging works?

Sure someone did... But you how some people are. |
I started two different long explanations that I never got to post because my work laptop keeps crashing. I'm not putting forth the effort again. Google it and read more just like we all did as newbs. I'm tired.
