that is some manly timing on pump gas :)

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 :giggle:

fundrive 08-06-2014 01:13 PM

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? :rofl:

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

Guess not :party:

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.

concealer404 08-08-2014 06:57 PM

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

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

fundrive 08-08-2014 07:10 PM

Fact is, there is some real boost now.

bcrx7 08-08-2014 09:10 PM

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)
