So, about the new Corksport turbo...

[ThOrZwAr]

So I pulled the trigger and ordered mine. Just got it a few days ago, I'm just waiting on my atp downpipe to come in before the install. Awesome service and prompt shipping from the guys and gals over at @CorkSport; as always. Justin@freektune; will be working his tuning voodoo once it's installed and good to go, so I'll have some logs up and post progress once we get rolling. I never thought I would be so glad my k04 decided to let go when it did, this is gonna be an awesome upgrade, I'm freakin stoked.

@adamizme You can always just the throttle tables too. @snailD's tables have worked wonders for my car.

Too bad you didn't get @CorkSport's DP. There's flows best for a stock flange turbo.

So...any one got any solid hp results yet?

Ummmmmmmmmm, no.

But you could pull off the "lightly bolted, I bought this car like this" card. Or the "I jus got an intake and a CBE" or some shit. For most licensed peeps, those answers/explanations will do, but that shit won't fly with a MS3/MS6 owner, or any dude that knows wassup.


Nice looking engine bay tho Loki! Well done.

This is exactly why I pulled out of the beta test. I have imperfect compression and didn't want to have to do a mild tune when what prospective buyers are gonna want to see what the best possible results from a stock block and from a built one. But so far, everyone is doing fairly mild tunes and its top end possibilities aren't being represented. Hopefully those who haven't chimed in yet will be doing write-ups soon and will put that info out there for everyone. So yeah, I'm still regretting pulling out cause I didn't want my write up to be full of excuses. Oh well, the turbo is young and we'll see what its future holds.

[acousticdefbot]

i have iron man in my engine bay. i will have arc reactor power to contend with once i have the funds to purchase this turbo.



probably not. but i will be running e85 and meth when i do.

[RJTSi]

Finished up swapping my built motor from my 3 (car fire RIP), a puppy, and some engine bay sex appeal over the weekend. I have a 3.5" intake on the way from Rambo (on FB, not sure of his username), so I won't be getting into tuning it much until I slap that on. But I am on a 30% E mix and only running spring pressure. I haven't ever messed with VVT values and I see some of you bringing it up. Can you guys link me to some of your or others documentation on it? Haven't really romped on it yet. Had to adjust the maf cal quite a bit and the motor only has 150ish miles on it. Will post logs and stuff when I get the larger intake on and do a little tuning.

Damn thats whats up. I thought the stock motor could only handle at most 350. That makes me happier.

See below. 400 isn't shit. Apparently.
big turbo stock block thread

[TiGraySpeed6]

400 lbft is still a safe torque level to aim for/stay below for most. It takes a quality tune to play with numbers over that.

The big thing is to get peak tq moved way up the rev range- you'll notice in the post linked above that tq doesn't exceed 400 till ~5500RPM and peak tq is over 7000. The problem we always had was from high tq numbers in the low RPM's, where even a K04 can do some damage.

[Voltwings]

38/38 was always my goal. 380 wtq at or above 3800 rpms is what i felt was good and safe.

[Chriss]

I'm planning 360 of tq and 350whp or a little more if my car wants to
I will be fully bolted with TMIC (except manifold), and 5 gallons of E85
I don't want more than 360 of tq because of OEM clutch

If you have good 93 and e85 you will more then likely get it. If your fully bolted then we are around the same mods and I hit 370 whp and 360 wtq(on vdyno at 75 degrees outside and CF of 1.01). Manifold is my next upgrade followed by a meth kit and probably a divorce.

[Chriss]

Yes we have similar mods, except intake size... I run a 3"
I use 94 gas with my e85 blend, so maybe my VD will looks like yours

[RJTSi]

So with my WGDC table completely 0'd out I made a very consistant 14 psi. I believe this tells me I have a 2-3psi drop from turbo to manifold. Most likely from the cx front mount which doesn't seem bad. With a revision I did yesterday I added 15% up top. Haven't had a chance to look at the logs yet to see what psi was obtained (targeting 17 psi) but it became VERY apparent that this turbo just rips all the way to redline without slowing down. So much more satisfying than the k04 drop off at 5k rpm. Unfortunately my flywheel bolts worked themselves loose. So tuning/driving is on hold until it's fixed

[lpugfan2004]

I would love some input from everyone. Turbo install Saturday with 0 issues. Started at 8 am and we were done and started the car at 2pm. I have attached two sets of 3rd gear logs. I am experiencing a ridiculous amount of boost creep, I am catless, its a gutted cat because it died at around 50k miles and rather that pay for another I just ticked off the code and gutted it.

The 'before' logs are immediately after install and warm up. I am still on my COBB intake due to a shipping error so my maf calibration from my k04 tune was brought over until I get my 3 inch maf housing and map harness.

The 'after' logs are from last night where I adjusted the length of the wastegate arm a considerable amount by instruction of my tuner to attempt to reduce the creep to find a place we can tune. The intention was to dial the arm back as needed before we start tuning.
@snailD; and myself see this as just a ridiculous amount of boost creep. Has anyone else gone catless with the CS Turbo? I don't think there were any beta testers.

The tune has 0% WGDC and targets .97 bar or 14 psi. Its just a base map. Stock map, cobb intake, catless turbo back exhaust.

Edit: I will make my own thread once I start the tuning process with a more detailed account of the install and my experience
Edit 2: Forgot to mention, there is a COBB 3 Port installed with the CS Turbo.

Any rough idea of hp/tq numbers yet with your mods? Very interested to see numbers with that intake setup...

[lpugfan2004]

its a base map with a shit ton of boost creep. I haven't even started tuning yet. Plugging the first log into virtual dyno for giggles shows 284/250, but thats very misleading and not the purpose of the post.

[RJTSi]

That's very strange. You have to have a leak somewhere in the ebcs lines or something. This turbo should not creep at all, unlike some other popular options

[lpugfan2004]

I have checked and re checked the EBCS and the lines. I even changed the turbo over to mechanical by boost source straight into waste gate and plugged the other side to the same results.

I will take a good hard look / replace the boost source line tonight just to be 100% sure its not the culprit, but I have spent the last three nights looking at the EBCS because everyone screams EBCS at me.

Forgot to mention, this is a COBB 3 Port installed with the CS Turbo.

[chaser27]

Have you tested the WGA by pressuring that with an external source and making sure it isn't leaking and actually moving the arm? And you've checked and rechecked the lines to your EBCS, but did you check to make sure the ports aren't reversed?

[lpugfan2004]

Yes to both, I hooked up an air compressor and dialed up the pressure to make sure the arm does move and does not lose pressure .

I have also checked the configuration of the hoses every time someone has asked just to be completely sure. I am using the directions from cobb but instead of using the T they suggest from the intake manifold source, I just pull my boost source directly from the turbo.

Rough paint job, sorry.

I am also using the Cobb 3 port. I would try hooking it up per their directions just to make sure that's not the problem.

[eat-sleep-speed]

It definitely shouldn't be a catless issue or turbo issue because I am catless and this turbo has been holding STEADY for me through every revision. I am on the stock EBCS however, so my guess is that is where your issue is lying there or some sort of a wastegate mechanical issue.

[lpugfan2004]

That is definitely good to know. I can spend more time with it this weekend to try and troubleshoot further. Over this past weekend I did try and bypass the EBCS by putting the boost source directly into the turbo to just run it mechanically/off spring pressure and the result was the same ridiculous creep you see in the log. The logs were basically identical.

[ThOrZwAr]

My CS turbo is going in this week and I'll be running catless with a CS EBCS. I'll post logs and let you know if I run into anything similar.

[RJTSi]

I am also catless (need to update my sig), running the same Cobb 3 port, and have no creep issues with it hooked up per Cobb's directions. Also if you haven't already, I would remove the brass restriction pill that comes in the vac line coming off the wastegate. Another thing...upon first install, i squeezed some of the Cobb vac hose onto the huge wastegate nipple. Well, when we pulled the engine today to tighten the flywheel bolts, we notices that the stress from stretching that size vac line onto there put a nice size hole in the vac line right at the nipple. With the motor in the car, I would have never known cause it would have been agains the firewall. So try to feel your vac lines, maybe even just replace all the vac lines to the EBCS. Would be a cheap way to rule it out. Did you have this 3 port prior to the turbo? If so did it function correctly?

The EBCS is brand new, I am going to take another look at all the lines tonight and probably replace them all. The restrictor pill line was removed prior to the turbo going in the car.

I don't think someone else tuning me is going to make me faster. That would slow me down. I just need more go fast parts. Besides, I am too busy right now beating the shit out of your turbo. I waited for a nice 108 degree day and targeted my Boost at 21.5 PSI (stock MAP) and watched my BAT's soar passed 150 as I ran out of WGDC. IDC hit about 120 but it still pulled strong until redline.

If you got a tune by one of the greats, I assure you it's possible. MAF log and a datalog posted, one of the masters can see right here if gains are to be had I bet.

I accept your challenge, I is going to go fast on my way home, post up the log, and you smart people can tell me what I thinks I already know.

You can drop a full second or more off your 60-100 if you get off that 100% Eth that is gobbling up your IDC and pushing you out to nearly 13:1 AFRs IMO. More boost (22 spool, reverse tapered to 24, feather out 2° of peak timing, and target 11.8 AFRs on a 3 gal mix. It's a bit more conventional.. but it sorta works.

Replaced all lines to EBCS, and by instruction of Corksport removed the arm from the waste gate, it is able to move freely. Then I removed the actuator from the turbo to disasemble. Everything looks as expected no visual defects or damage.

Next step is to hook the stock EBCS up in bleed mode to rule out the COBB EBCS

I think you already ruled out any ECBS with hooking boost source directly to the WGA. Maybe the WGA preload is adjusted wrong?

[shamie]

How loose is the actuator arm? If you disconnect the hose from the actuator you should be able to run just on spring pressure and see how that behaves.

That could work, but I won't mix fuel because I ain't no pussy, so that's out. How about I just give my ECU more authority to add and take away WGDC to hit desired boot targets. High boost is 21 psi tapering off to 16psi. Then give myself a bit more of an earlier fuel event by tweeting the phasing from 1.0 to .96 thus lowering IDC a bit more.
Now that I clearly taxed out my stock fuel system, I obviously need some sort of aux fueling which is currently on the drawing board. I don't know if I should use port, WMI, or my custom guaranteed to blow your shit up injectors.

It's also possible that my shitty loose stripped 02 sensor is causing read problems under extreme operating conditions. I need to get a downpipe and install the new sensor you NATORed to me. I only say that because before I would normally run out of fuel at 125 IDC before my install. And even at 125 IDC, I would not see lean AFR's such as these.
