European´s 100 octane is like 94 US fuel?

You wouldn't NORMALLY run that kind of timing on an FE3, though...

But this one has the Wossners.

Stock high-mileage F2T, HX40.

250kpa? I thought you were running MANLY boost

250kpa with a HX40 is a lot of flow.

I don't run an HX40, nor do i run a standalone. I couldn't tell you what my timing maps are at 30psi. I DO know that they're substantially more aggressive than stock, though. Does that help?

I was actually kinda surprised by that screenshot, thought you finally saw the light and got rid of the AIDZ

Guess not

If the car ever gets a built bottom end (it won't), maybe. Until then, ain't care.

Back from garage:



Manifold gasket leaks. You guys know your stuff. Interestingly there was no smell or chirk. Maybe it leaked only under load.

And I found a problem in my logs with the MAT-sensor temp. As soon as the engine gets hotter, the sensor stays at enginebay ambient temp. It pulls a lot of timing.

Thank you guys! Bye for now!

Take it easy the first time you go out and boost it without the leaks. Don't blow it!

Hi!

Update:

I wrote a update on my boost problem 5 or 6 hours ago, but decided to go back to garage, where the shitbox sleeps.

I´ve done the following "mods" in the last two days on the "car", but nothing has changed except the boost starts roughly 300 - 500 rpms earlier:

- machined the manifold flange flat
- ported and cleaned up the turbo collector
- checked cam and ignition timing
- new gaskets on manifold flange and turbo inlet
- new sealant between the comp. housing halves
- upgraded the new tial clone wastegate to my old turbosmart
- watched a southpark dvd in the meantime
- hocked up the pcv valve hoses correctly
- cleaned the enginebay look from nearly ghettostyle to suburbanstyle
- connected the wastegate-line to the inlet manifold

But:

Sitting in front of my car, with brain mode on (what a experience), i´ve decided to hock up a "screamer pipe" to the wastegate down to the road near the oilpan.

Thereafter, once again, went out for a testdrive on our small german village roads.

And.....baaam.... 14-17 psi. With 20+ psi worth of wastegate-preload. God save the overboost cut. My ve-tables and timings are safe, so no damage.
There is some serious high pre-turbo pressure.
Running a open dump is not a solution, so I need a professional made manifold.

My self-imposed budget to build the car is nearly depleted, rest of the budget was retained for some future rods and cams.

I´ve decided to sell the GT3582R. For the money, a good manifold. No future plans on turbo-sizing, brand or Pmax.


Conclusion: I have underrated the small, but important things. Underrated how fast the car is even at 14-17 psi. And overrated my skills to build a high hp car.

A dream comes true? Not always.

I can't brain how that would fix things...

Improper wastegate placement should INCREASE minimum boost, not decrease maximum boost.

Fact is, there is some real boost now.

How have you plugged the other side where the wastegate connects too? You sure you don't have a plugged CAT and now the hole where the wastegate connects to is providing the exhausting means from the turbo? (Sorry if what i think your exhaust looks like is not correct)
