nope, its boost activated. I think its a cool idea, I just worry about placement

Leaking wasn't on my mind. After your comment, I placed the valve up to my mouth to see if I could pressurize/force air through it. Unfortunately, I can pretty easily, lol. So you concerns are warranted. SO! Assuming I relocate the O2 bung, I'm still left trying to find good placement so I don't get exhaust in the car. And for anyone wondering why I don't purchase a 3" exhaust: 1. I want to keep the noise down as to not bother the neighbors. 2. I want to keep my cat, for times where I'm not full on it. 3. This option will likely flow better than running through a full 3" exhaust. 4. 3" exhausts are expensive (though at this point, the idea is seeming more attractive). Note: I obviously don't claim to know what's best here, so any recommendations are always welcomed :). I'm just here to have fun, after all. |
You can rationalize it however you want but I haven't once bothered my housemates when I take the car out at night even though they're asleep. I'm running a Kraken 3 inch exhaust with the muffler swapped to a big Maggie.
Seeing you have to go through all this rigamarole for something that has such obvious solutions makes me sad.... |
I have a cheap electric cutout I'm planning on running for similar reasons. Quite when I want with better performance on demand.
I haven't mocked up an exhaust or anything, just took everything to the local muffler shop and got "yea I can do it, probably $200 or less". In my head I'm hoping to have the O2 about 6" from the turbo and the cuttout about 6" from that... I want it before my stock cat. From my reading (mostly on v8 applications) should be fine at cruise and definitely ok at WOT but my affect idle. The farther back the cuttout is the more consistent the afrs will read so the easier it'll be to tune. I'm only planning on using it on "high boost" and WOT. I'll mostly drive around with low boost and it closed. (I think lol ) |
That's a little close to the Turbo with the O2 sensor

Upper down pipe is done. If all goes as planned, I値l be able to fire it up and put some miles on the car this weekend. Then next week I値l be revisiting the exhaust cut out. https://cimg6.ibsrv.net/gimg/www.mia...b7fb2ebb4.jpeg |
Assembled. Been working out some bugs. https://cimg0.ibsrv.net/gimg/www.mia...c7737b657.jpeg https://cimg1.ibsrv.net/gimg/www.mia...bbffe800e.jpeg |
Can anyone explain to me why the Hallman Boost controller recommends NOT running anything to the top of an external wastegate and feeding boost through the side port, while the Precision Wastegate recommends running the boost controller into the top of the wategate?:
I will say: Following Precision's directions, reverses the way the boost controller works. (Tightening it compresses the spring, which feeds less pressure to the TOP of the wastegate diaphragm, allowing the wastegate to open SOONER = LESS boost. While with the internal wastegate, tightening the spring would still compress the spring, but feed less pressure to the BOTTOM of the diaphragm, allowing the the wastegate to open LATER = MORE boost). This means the adjustment dial on the boost controller now reads backwards. :dunno: http://www.hallmanboostcontroller.co...tions%20ld.pdf https://cimg0.ibsrv.net/gimg/www.mia...8f67b41609.png https://www.precisionturbo.net/tech/...structions.pdf https://cimg2.ibsrv.net/gimg/www.mia...b34eb561c1.png |
Regarding the question about, I知 now pretty confident the Precision directions are referencing a Bleeder type manual boost controller, while Hallman is referencing a Ball/Spring type. When I setup the controller/wastegate as Precison recommends, the boost controller either opens and equalizes the pressure on the top/bottom of the wastegate diaphragm (keeping the wastegate closed and allowing the car to overboost), or stays shut, (adding no air above the diaphragm and thus allowing the wastegate to open on spring pressure). So I will be replumbing it to align with Hallmans directions and we値l see how it acts. Doing so will also make the dial adjustment screw on the controller, read correctly again (counter clockwise = more boost). |
If you have a 2-port EWG and an MS3, why are you screwing around with a manual boost controller?

Updates: 1. Hood vent 2. Wrinkle paint valve cover (+50hp, I know) 3. Chopped up exhaust at the welders. https://cimg1.ibsrv.net/gimg/www.mia...2e95f028f.jpeg https://cimg0.ibsrv.net/gimg/www.mia...73a288a98.jpeg https://cimg2.ibsrv.net/gimg/www.mia...779d4a0ea.jpeg |
Nice!
But that turbo inlet/filter are terrible and likely hurting your power |

Yeah, although maybe it's just a weird angle and I can't see it fully, but looks really small and restrictive.

Alright gents, here's a snap shot of some very very preliminary results. Still much more tuning to be done on the new setup. I also need to check for any hot-side pre-turbo leaks in the system.
As it sits now, it takes nearly 1000K RPMs more to hit 12psi lol :greddy:, but again, more tuning to come. Other notes:
|
F****! I知 95% sure I forgot to install my wastegate valve seat! Which is obviously contributing to the comical spool. Investigating tonight! |

Once again hitting 100+ injector duty cycle with anything over 27psi. I'll have to read up on whether it's the injectors (Injector Dynamics Fuel 1050X), the fuel pump (Deatschwerks dw300) or something else in the system
|
Are you sure you have it programmed right in tune? 100% duty cycle with those injectors and that pump in a miata would be a fuck ton of power. More so than that plot hints at.
