I take that Back. Frames 4500-4550 on log #1 clearly show 255kpa by 3397rpm in 4th @70mph.
It seems that for now the ETC is the enemy. The boost curve closly follows actual throttle position.
Alrighty I tried a dual spring in the gate. Too much. Im glad I had the 2nd map unclamped for safety cause I really dont know how much boost it's rockin. pegs it @255kpa by 4k.
It gives me about 3 deg KR at whatever boost it runs before the throttle shuts down.
Looks like I have to pull that darn gatecup off again and take the 2nd spring back out.
The tune has alot of work to do, mainly with sorting out the boost curve. I'd like it to run around 240kpa for now.
You'll notice how it takes a little longer to get to (30?) psi than the 11psi from last night. I could get 11 all in my 3K. 30 takes another thousand I guess.
The real tuning will begin when I tap the Turbine housing for the 4bar sensor. I will put as much overlap as TIP/MIP will allow me, making for an even quicker boost curve and more top end power.
lastly the intake pipe needs redoing. It didnt come out perfect, and being in the emotional state I was in over Moe- it got a large dose of Irish temper and a clawhammer. I felt better.
I'm currently testing with a 3" piece of neoprene brake ducting and the Filter from this summer's intake.
I may take the easy way out for now and weld up a 3.5" aluminum version to get things into production sooner.
I was just gonna ask about opinions on that very topic. Is that the consensus folks? Tigwelded aluminum for now? It will take several weeks off production lead.
Hrm now you said that you were getting 3 degrees of KR no matter what boost you ran?
Once you've figured out the pump limits, we will need a little more hardware work.
You could probably remove those 4 degrees and add another 30 whp by manufacturing tubular manifolds...
Or by manipulating the VVT (eventually HPT). I'd say less timing, and more boost.
To think, the Intake and exhaust manifolds haven't been touched yet. You are still on stock cams and head work... : O
You already have the upgraded intercooler right?
I'd love to see how you are going to integrate a 4 bar into the system...
Well another ride This time I filled the HPT module. about 45min of unadulterated assswhoopin' Turbo and header were BRIGHT red. Only picked up about 10deg worst case with the intercooler. Wonder what the pressure drop is. Could be a little scary!
lowboost=15-16psi runs about 29 lbs/min. still a little KR. Guess I'll have to play with timing a little.
Highboost = 21psi for now, Time to clip the MAP2 again and work back up to 250-280kpa. First gotta get KR back in line.
Only video camera I have that is functional is my Cell's Vid. Hopefully it wont suck.
Supposed to get 2-4 inches tomorrow. Hopefully I'll have time to rip off a run or two.
If it's going to be crap all week Im goignt to remove all the turbo parts, re-jig a piece of the cahrge pipe, tool up for the Intake pipe and start rockin' production even before I dyno it. The hardware is all there.
you can have it 2 flavors. Blow thru or draw thru. Either works great.
Tial dumps volume real quick. If it wernt for the ETC f'n up the program there would be ZERO boost loss between shifts.
Havioing the BOV just 2 foot from the throttle plate help by not forcing the entire intake tract to reverse directions twice on every shift

Yep stock IC, stock catback. Only thing thats aaftermarket are my turbo setup and catless DP. I want to see definitlively where the pressure drop begins to be a serious impediment.
Then build a ncie big intercooler using a garret core. Just havent decided which.
At high boost:
Inlet temp
Outlet temp
Inlet PSI
Outlet PSI
I think the TurboSol intercooler is significantly bigger than the stock STi intercooler (which makes 300 AWHP). Plus, it's front mounted. So I'm not sure it's that big a limitation.
haha 5 month old 93 octane from when We put it away. Likely the source of the knock. lol.
It just did something odd. I reflashed it to alter cam timing for more advance on the exhaust cam and a little mroe retard on the intake in the ranges of 3000-5000.
Anyway it was stone cold (and I mean cold since it's just above freezing right now) it idled for about 2 min then choked black smoke a bunch of times. Driving down the road it was no better, I could part throttle my way through the rev range but floor it and it flooded it.
After 5 minutes of drving it was fine. In fact performed very well.
I think condensation from the intercooler is hitting the MAF element in the charge pipe.
We may have to move it to the hotside of the intercooler.
