Fazdarx_8's Top Mount Turbo Build
I would love to provide more results but Mazdamaniac is not tuning til the 19th. I did submit datalogs via email, but I haven't gotten reply like before, I believe he is just going to wait til the 19th for everything
that funny noise from what I gather is air going into the intake, around the rotors?(cold motor) and out the exhaust.
I adjusted my preload and got more boost, so its about 8psi now, I wanna keep it this low until I get more tuning done, Advised by Jeff. regardless if I go into boost my afr's max out at 10.88. according to my wastegate settings it at 10psi, and sense my signal is before the intercooler that makes sense
the system I think starts to spool at 4ish and get full boost at 5ish. it pulls strong. vacuum at idle is still good at 18-20in/hg
no overheating problems what so ever, coolent temps are same as stock boosting or not, charge pipes aren't hot either.
I would like to add a turbo support bracket
I also have a small leak on the wastegate recirculated part, IE not on pressure side just got to seal it up.
I am really hoping that I will get the tuning done on the 19th, wish it was sooner!!!!

Not yet.
And it's not nearly as pretty as yours.
Next winter I will rip it all a part again and get it fab'd up all pretty like.
I'm missing a radiator and I don't have what I would call an acceptable downpipe to midpipe connection however it's functional.
Other than that I need an oil container for the Sohn and a Oil Catch can.
Making sure and/or finding the correct Oil Restrictor has been the hardest thing, I'll use the one that came with the kit but I'm 100% sure it's too big.
So those are the only things I'm missing.
Everything else is installed or in some state of being installed, except the battery relocation kit which is sitting on my workbench.
The last 20% of the install has been the hardest.

Sooooooo jealous
I have her running and I am on 4.01 tune from mm, just wanted to ask a few questions
I am strictly using the waste-gate as my boost controller so it might explain some stuff. I have set up my waste gate for A & D, I can hear the turbo spool at 3800 rpms but full boost really doesn't happen til 7k to 8k @10-11psi where it really kicks, it seems as rpms build the boost builds.
but I don't get the, what I thought was common, 4-5k full boost to 8k-9k.
is this because I don't use an EBC?
My boost signal is right after the turbo. and at those settings I should be seeing 13.5 psi, perhaps the intercooler dropping 2psi?
I will say that I don't do WOT and that can be my issue too, I don't because the tune is 10.9afrs after 4200 rpms. and 10.9 is the limit of the stock 02
so does this sounds right?
the car is acting much better now that I have the manifold leaks fixed, the boost feels great, I just want to make sure everything is right so I don't have a tune on a faulty setup
oh and when I changed the springs and inserted the smaller seat, I noticed that the wastegate doesn't seal the exhaust gases 100%, is that normal? I can take a flash light to it and see a little bit of light
all exhaust leaks sound and seem fixed

Possibly.
I sent an email to synapsis support, so I am hoping to get a reply back tomorrow.
perhaps after a few heat up and cool downs it might seat?
I was reading some where that wastegates by themselves slowly open as the boost builds, but with an EBC you can make it so it only opens once desired boost is achieved. resulting in quicker spool up
is that correct?

I think thats something like wastegate cracking pressure...im not terribly well versed on the subject either, but you know how i feel about boost controllers...
When do you expect to have the kinks worked out of the system?

I also see 6psi (full boost on the WG no ebc) at less than half throttle i think in mid 40%.
Yes you are correct on the boost controller. Mine is allat 0% right now resulting like its not there. I will be finishing up tuning with the controller soon.
I have the copper ring in,the exahust system is sealed from the out side.
the valve on the inside that opens and closes. Its normally closed. When I was messing with it to see when it opened and saw how preload worked, and changed springs and such, thats when I notice that the valve didnt fully seat closed its a hair line opening, thats what I was talking about.
Maybe when the car heats up it seats?
Car feel really good after it really warm
When I was at 5 psi I could do that at partial throttle and get full boost too.
I think everything is fine, I think I am just being hyper observant.
May 3 is only 2 days away

The update was posted at 5:24pm. I'd say that was a bit less than 90 minutes. My computer crashing had no effect on your submission. I was "down" for less than 7 minutes. You signed back in at 6:27pm to download your files.
However, it does illuminate a point that I'd like to bring up (and will mention in the other thread) that I believe it is somewhat presumptuous to come in at 6:49pm - when the session is over at 7:00pm - and expect another calibration. Don't you think?
