I think that you will be at full boost by 5k

 

+1 had one on my auto d15b. 5k was full spool

 

ok thanx guys. I think Ill start building the new setup next week.
Im going for a obd0 ecu (pm6) with a turboedit tune. i have never done it before, but i understand the program, and the meaning of the a/f ratios, and ignition. but ill keep my fingers crossed.

i still dont know how to datalog the info. but i can use a wideband )2 sensord with zeitronix. and maybe an EGT sensor. i dont know whats a good temperature. 850 degrees celcius max?

 

850C would be getting high, 750-800C would be more of a target 'max'. If you made a 'det can' (homemade detonation sensing system) you could tune timing fairly well. Find where it detonates, reduce timing until EGT's get very high, then set at the in-between. Idealy you would finalize it on a dyno, obviously.

One thing about the turbo, it should have a stg1 turbine wheel. A lot of USDM Volvo/Saabs use an interchangable .48 housing, and you usually find people who have them but don't need one. FYI I had a buddy with the same turbo on a SiR B16A, and it would hit full boost at 4k with an SSauto manifold w/tial 38mm. I've also had experience with my D16Z6 using a very similar turbo (t3/t04b s-trim, actually flows more) hitting 10psi by 4k with internal WG and full 3" exhaust running an HF manifold.

 

HiProfile, Thanx for the info!

So I have to aim at 750-800 degrees celcius. or its just a absolutly maximum? (critical temperature?)
I am going to build a DIY knocksensor. i dont know how the DIY knocksensor will preform. I never heard knock before.
When I hear knocking, isnt it already to late? and my engine destroyed?

so if I reduce the timing, the EGT get higher? what if it is not knocking, but is getting like 800 degrees celcius?

 

Engines can knock and not get destroyed.. You just don't want them knocking for long.

When you reduce timing, you're causing the fuel burn to start later. Eventually, it's so late that the fuel is still burning when released out the exhaust valve. This can burn a valve, destroy pistons, even cause coking in the oil at the turbo. Trust me, you need an EGT sensor to tune timing.

How high a EGT to watch out for depends on where you position the EGT probe.

 

whats the best position for an egt? in the collector? or use 4 egt's in each runner? ( I think using 4 sensors is not an option for me, but if im lucky the turbo comes with 5 egt sensors)

If I advance the timing, will the EGT get lower or higer? If timing is reduced to a point that the fuel is still burning while the valves are opening will the EGT get higher?
