OK,got it..

Have you adressed the rod bolts?

Rod bolts？The rods with ARP bolts, maybe I don't have to worry about it, right?

Also, stock block holds 25psi with upgraded hybrid turbo without issues. I'm the crazy one running this setup at the moment.

I wish OP well, but this appears to be some kind of Devcon filler to "close the deck" and use a parallel repair sleeve. Would not recommend going this route. Would recommended sending block to CSS and having the cylinder coating reapplied, or get a block + Darton sleeves installed + CP pistons from navardi tuned, or can get mid sleeves made + installed from LA sleeve on the west coast.

Many people drop sleeves and have total engine failure when pushing over 30psi with parallel liners.

Hey guys, may i see your BM3 log please?
I found my mass flow reading was to low, near 29lb,but it should be 35-36lb
I'll try to find out

I don’t want to share logs with this publicly, however to get the MAF to read 35-36 lb/min, you will need a turbo inlet and cold air intake. My setup for that is afe magnum stage 2 intake (whatever this means) and the ftp turbo inlet. Tuner can get a little more flow as well with boost and load targets. Otherwise the stock MAF sensor within BM3 (software limited) won’t read higher than 35.8 lb/min. You can achieve a little higher than this by logging in metric and it’ll show up to 37 lb/min when converted from metric (anything over 974 or higher logged is 36 lb/min) imperial. Rule of thumb is take the metric number and divide by 27.2 for a rough estimate

Got it.It seems that the difference between us is the ATM 6.5' intercooler & Saber 6.5' intercooler, and KN high flow filter.

MAF reading in my log shows that
3500 RPM MAF 22.1 Mass Flow HFM 20.2
4500 RPM MAF 30.1 Mass Flow HFM 26.1
5500 RPM MAF 36.8 Mass Flow HFM 29.7
6000 RPM MAF 37.4 Mass Flow HFM 31.1

Readings deviate more as RPM increases. I have seen your log last year, this is the reason I replaced TTE400. In my memory your deviation is not so much , only about 2lb.
So I am a little curious, I have never seen such a deviation in other log data.
In the afternoon I will replace it with a Wagner Tuning EVO2 intercooler, and re-record the log to analyze whether the difference in the intercooler caused

this number here " 6000 RPM MAF 37.4 Mass Flow HFM 31.1" the MAF data for it to max out is:
MAF 37.4 - highest it'll read in BM3
"Mass Flow HFM 35.8" - highest it'll read in BM3.

This is an older log on 93 octane before I swapped to metric. Boost is different now (holds 25.2psi to redline) + more aggressive load targets + WGDC:

Your pictures are amazing, thank you so much. That's it, you can get over 35.8lb, I never got over 32lb, 31.4lb is the max @23-24psi
1 pound represents 10 horsepower, which means I'm losing a lot, and that's what I'm trying to work around.
Wagner Tuning EVO2 intercooler being installed, I'll re-log when I'm done, hopefully that fixes it
You're maybe making 400WHP now? Great work

Yes arp rod bolts, they are usually the failure point.

[MaverickCruise]

I hardly care about MAF, the sensor reading seems to be wrong, I can clearly feel more horsepower, but the MAF reading is still under 31lb

With the help of navardi, we found that it seems that the stock BOV cannot be stabilized at 25PSI, and there will be large fluctuations after reaching 25PSI.
I'm buying the BOV from turbosmart that navardi mentioned, hope that will fix the problem

Recently I saw a guy running 27-28PSI, ignition 12 degrees. 60-160KM only took 7 seconds, which seems to be a good reference.

[sqwinny]

Turbosmart is the only thing I’ve found that holds the boost and doesn’t leak.

Gfb leaks above 335 whp on 93. Forge leaks around 340 whp on 93. Turbosmart holds without issue. Talked to turbosmart and it’s the same kompact unit that’s used on n55, GTRs, r8s, etc that see 35+ psi through them at events.

Recirculating version makes no noises (car sounds like stock), dual port is dual port and brings a “BOV noise” for anyone wondering

Man, I've done a lot of testing and still can't keep 22psi above 5200rpm, 6500rpm will only be 21psi
I am stuck...

Can you maintain 25psi till 6500rpm?

[sqwinny]

There are too many variables for every persons car.

What fuel are you using ?

List all your mods and self mods you did (that wastegate actuator arm mod was pure BS).

Idea is you peak boost and then use the least amount of boost to hold the air flow through the turbo.

95RON

TTE400turbo
FTP V2 Turbo Inlet
FTP Charge pipe + Boost pipe
WT Intercooler
Turbosmart DV
JBOM Catless Downpipe
335i muffler
Aquamist WMI system runing 700cc 100% meth

I wish keep 25psi to 7000RPM
here is the log,I'm very surprised why?

[sqwinny]

This turbo doesn’t make 25psi to 7000. It is a td04-19T. Thus 21-22 psi is the max at 7000 rpm or so. It also depends on fuel. 95 Ron is similar to 89 octane in the USA. Thus boost require timing which requires a proper octane. Methanol injection can help, but isn’t a 100%.

Looks like for your environment the turbo is maxed out. If you are PWG that’s harder for boost control but it looks the best it can do.

Are you at sea level or what’s your altitude ?

Thank you for your reply, I am basically at sea level, not more than 80 meters
I see you can still maintain 24psi at 6300rpm, so 6800rpm should be at least 23psi
I also have a log of a test process that can reach a similar level, but the pressure fluctuation is very severe

Are you electronic waste gate or pneumatic waste gate ?

My “stock engine tte400” record turbo run peaked 23 psi and held 21 to redline. More boost =/= more power after flow is maxed out.

electronic waste gate

It looks like I'm currently performing about the same as your previous stock engine TTE400.
How is your stress performance now? Peak 25,then 24-23 last to the red line?

I have a development cam mod at the moment so using boost to redline doesn’t exactly give the same results to compare apples to apples.

I'm almost done with the final adjustments at the moment, I'll switch to the AFE intake kit in a while and log again to see if anything changes

No need. Hit the MAF HFM channel and post a photo. Curious to see if you are flowing the same if not more air than me. If so that means you may be faster

To be honest, my mass flow reading has been consistently low, even among the people around me. On the contrary, your mass flow reading is the most I have ever seen
