Winter is coming. Keep going man!
I'd be very disappointed if you don't show the highest M2 dyno number that's ever reported.

Assuming there's no snow on the ground when I return, I'll relog and see if that fixes it. If not, I'll have to do the EWG re-learn procedure in ISTA and adjust the WG adjustment nuts as my last resort.

Endeav Just "tuning" into this build (don't know how I missed it) and very impressed with what you have done here so far. Wish I had the knowledge - read as "balls" to try this myself.
Colour me subscribed. Looking forward to the dyno results! |

That being said, I was able to test out of the new manifold for one drive. No issues with the new manifold, however my higher-than-expected WGDC still remains so it looks like it wasn't a leak between the Fuel-It PI spacer and the intake ports on the head. Since I've extensively tested everything between the turbo and the manifold for leaks both via pressure and smoke-testing I can only imagine my wastegate rod is set too loose. It's really the only thing left to check. My first project over the winter will be to clean up the methanol lines in the engine bay as well as make an EWG adjustment. I plan to tighten the EWG rod by one or two turns to see if that's the reason as to why I can't seem to crack the 20-21 PSI mark. From what I've seen from other PS2 logs my WGDC should be more like 60-65% at this PSI and not 90% - I imagine this has to do with me "eyeballing" the EWG nuts when I reassembled the turbo. Oops, lesson learned! To answer your question Natek about the PS2 turbo around town. I honestly don't notice the lag too much. Even with the OEM turbo I was always fairly keen to downshift prior to passing / punching it. I imagine if you're more the type to just roll into the throttle from low RPM the PS2 turbo lag would be much more noticeable, however with a quick downshift, the lag is pretty much non-existent. It's a fairly responsive turbo just by nature of it being a "hybrid" turbo. Don't get me wrong, it definitely has more lag than the OEM turbo, but it's not so laggy that it's no longer fun to drive around town. Hopefully this helps!

PS2 PWG will be low at 60-70+%. EWG rarely drops to below 80+% even at stock boost. 90% in your case is reasonable, especially with piggyback. I'm inclined to believing boost issue is tuning related.

Essentially what happens in my datalogs is I'll be targeting 21 PSI throughout the rev range. The vehicle will build boost and hit target, but as the RPM climbs boost begins to taper off from 21 to 19 PSI while WGDC rises. By mid RPM WGDC is around 97-98% and boost is off by 2 PSI from target. Long story short is it acts like a traditional boost leak despite me being 100% sure there is not a leak. I have tested for leaks extensively. Having described the situation, I'm a little hesitant to think that it's still a tuning issue just by the way it's able to hit target but tapers away from target as RPM climbs. The JB4 is outputting maximum WGDC to the DME but for whatever reason it cannot hit target. I feel as though this could be because the WG arm is too loose. The EWG motor is maxed out in its movement range but it doesn't necessarily translate to a maxed out WG position. That's my reasoning anyway. Thoughts now that I've explained the situation in detail SeanWRT? I really do appreciate your input. I'm kind of down to the last few things on my checklist of possible causes.

Endeav, WG duty is an indication of the difference between the boost dme see and it targets, plus jb4 duty bias. Nothing else. It does NOT mean how hard turbo is working.
Dme usually see low boost with Piggyback, leading to high duty. Boost target is a complicated thing, you can have underboost and dme is not even trying to close the gap, and have overboost and dme still pushing. With or without piggyback. You try 24psi (your hardware can), it'd still do it and taper. See for yourself. Anyway there is the whole N54tech board and the mighty Terry to ask, why didn't you? Also you can send me the log. Will see if I have useful input thru PM.

I'll be honest and say I've never tried running higher boost, main reason being that I saw the taper and high WGDC and stopped because I assumed there was a boost leak that needed to be fixed. I've also contacted Terry about this via e-Mail as well as on N54Tech and long story short he said he it looks fine and would leave it where it is. Ideally I'd like to run 22-23 PSI but have it be flat boost. I've PM'd you a couple logs. Thanks!

Octane is enough, fueling is more than enough. Time for more boost, I'd do 24psi immediately... and wait for the turbo fail - joking

If you're right, come spring I'll up the boost on the JB4 and see if it responds appropriately. Probably still have the taper because of the BEF like you mentioned, but should be able to hit 23 taper to 21 PSI safely. Thanks for your help and insight!

You and me both
Exchanged a few e-mails back and forth with Terry from BMS and he seems to think he can squeeze quite a bit more power out of the vehicle. He says the "high" WGDC values in the log don't actually mean that actual WGDC is maxed - on EWG vehicles it is an additive value and doesn't directly reflect how hard the turbo is actually working. Sounds very similar to what SeanWRT was saying. Here's hoping for a quick Spring so I can pull the M2 out of storage and get back to work!

Once the temps start warming up and being more consistent I'll get back to datalogging and working with Terry. I did install a CTS Turbo intake and clean up the meth lines feeding the PI rail prior to pulling the car out of storage. Here's a photo of what the engine bay looks like now!
