The 2nd MS6 Build-a-Beast in the country!!!

I don't think you're running a valid test. Follow me here... The WG passage and the "flapper" are the same item for any level of boost wanted on the 3071, so the WG must flow enough air (exhaust) to control boost all the way up to the max the turbo can flow. If you run WG only, the boost output will likely settle at ~15psi for the 15 psi WGA. It may only take 5-10mm of flapper opening to achieve it. If the WG flapper were fully open at your 15 psi input, the 3071 WG could not control boost at 22+ psi. Your boost controller must be adjusted to hit the actual level of boost you want to run. My theory...
If he has the 15 psi WGA on his 3071R and has an aftermarket IC and exhaust it will not run anywhere near 15 psi it will run between 22 and 28.
Mine with IC, DP and no cats ran 22 psi minimum but with my cutout open it wouldn't go below 28 psi. I even ran the WGA looped back on the outlet from the turbo (= 0 additional boost) and still wouldn't work right. This is why you have to run the 7psi ATP WGA.
 
skylinemonster,

I am having the same issues as you.

Are you looking to fab up a custom up pipe for this setup???

I am going to mess w/ the wastegate actuator rod before i do anything crazy. ATP says to adjust the rod. IDK if this will do any good but worth a try. porting the gate might be a good idea as well but gonna be very time consuming.

porting the gate to mitigate boost spikes is something that the man himself, Corky Bell, recommends as a good step

Hey there. I haven't heard of this technique. I will look into it. Right now I have the boost pretty much stabalized at 20 psi after adjusting the aem tru boost gauges spr settings and the boost duty cycle on this solenoid. What I do find happens is boost cut around 5500 on full boost is taking place. I can't use the standback's boost clip settings because I dont think this adjustment works if you are not running the factory wastegate solenoid which I am not. I don't know if I should end up using a map clamp or not. I was going to run a custom manifold with external gate but the manifold is on backorder and I would just rather keep things simple at this point, especially since I have the boost ramping up to 20psi quickly and holding. I do have the 7psi spring in it now, which fully opens the flapper at 20psi using a regulator. Currently the car is partially tuned but I think the tuner is afraid to run some well deserved boost on this car. I want 24-25 psi on this turbo all the way to 6500. I am getting the cp-e full control reflash next week, so the throttle plate will be right as it should along with some other improvements. I am willing to drive my car out of state for some tuning. Please give me some recommendations if you don't mind. I have almost 5000 miles on this new engine and everything is tip top. Modified the factory exhaust manifold heat shield yesterday so it would fit with the gt3071. It dropped my engine bay temps by 40 degrees f. I am also getting excellent gas mileage. Went to cedar point today and was able to get 312 miles with a quarter tank left. I will get about 410-420 miles until she is empty. I made sure to stay in vacuum the entire time driving. I was impressed considering i'm running super rich and have the bigger CDFP, not to mention a gt3071. Talk to you guys soon. Here are some pics I took today:

By the way it appears so far that Ken at protegegarage.com builds really nice bottom ends for this car. Compression is perfect, there is no piston slap, and the rings hold oil. I am pretty impressed. Thanks Ken!!!
 
To quote late 8...WOW

I justread what happened to your motor. Same thing happened to me about 6 months ago actually i was cruising at 80mph 3200rpm and the motor just blew up. Funny thing is my piston looks just like yours, hairline fracture right down the middle splitting it in two perfect pieces... i now call them modular pistons. At this point Im fairly convinced it is due to a metalurgical problem.
Car looks amazing man...good luck!
 
***update***

The car is still running strong. Over 8000 miles on this engine. Car was on the dyno for a bit. ATP turbos absolutely induce boost creep on their internal gate design. After adjusting the aem truboost, I was able to pull 290hp 290 ft/lbs on 19 psi at 5250 rpm because I hit a boost cut. This dyno has stock STI's at 215-220 hp. I now have a protege garage equal length manifold and an external tial 38mm wastegate that is in the works and should be installed next week. I also have a split sec electronic map clamp which takes care of most boost cuts. I also just installed the HKS twin power ignition yesterday and I must say, I can't believe I didn't purchase this sooner. It's a world of difference. Faster spool, smoother acceleration, more power up top, worth every penny. I am very confident the car will spin 340-360 on the mustang, at 24-25 psi based on my current pulls and I will be very content with this. At the crank it should yield 430-440hp. I also picked up a gizzmo shift light and 2-step which should help at the track. I'm almost done with this car. My goal is to get this car to make an 11.8 or lower pass. This will then become a Mazdaspeed GTR.

Congrats on the numbers. But they seem low. I know different dyno's ready differently..blah blah blah.

But there are mazdaspeed3's pulling 300 on stock block.

Could you please elaborate regarding the boost creep issue. Are you trying to say that it's spiking uncontrollably?? What boost controller are you running?

-C
 
whoosh dyno'd 382hp (somewhere around that) on stock block in his speed6. Unless I'm completely misinformed.

whoosh did back to back 386awhp/349awtq pulls at Verocious Motorsports in Delaware on the completely stock block and head on 8/28/08 @ 10am

that's with no tuner but he (I) have the cp-e throttle plate flash:cool:

The dynojet will read 50hp higher than this dyno. Look at this bone stock STI for example in this picture on a dynojet. I have a evo dyno I can post as well on the very same dyno I am on which spun 360hp/376tq and he is consistently tracking low 11's. All I can say is the track does not lie.

OK so 386 minus 50 as you say is still 336awhp on the stock engine/head with no tune vs. your fully built and tuned 290>>>still significantly higher

I guess you'll have an EVO or STI comparo excuse to use for that as well???

my car has consistent power and pulls those numbers every time, not a fluke pull or one timer as my dyno graphs, videos, etc etc prove (posted on the forums I frequent)
you like others on the forums just post numbers that you "say" have happened rather than take the time to properly document the results.

I do agree the track is the the place to settle all bets
I'll compare my timeslips to yours after you run your car...just let me know

let's line em up Skyline!

BTW, I was just correcting the info Parad0X01 posted

It's only a matter of time on those rods, but im sure you already know that. I'll have video and timeslips so there is no controversy or discrepencies. I am curious as to why your hp is significantly higher than your tq though. I have no problem doing the honors and being the first 11 sec speed on here. I think I'll change my name at that point to "PIONEER."
 
can't we all just get along...

good job to both on the builds. hopefully they will both last and be beasts for years to come.

it's all in good fun
"but"
with your HP level, axles, diff issues, gearing, etc.

GL with 11's anytime soon.

as for the pioneer title, call yourself whatever you think you should be called but buying off the shelf parts and slapping them together is hardly pioneering anything
