PETERPOOP's Turbo Build Thread.

[PETERPOOP]

I don't know where you can hear any compressor surge in that video? There is very minimal compressor surge, or if any with this BOV; as far as I can hear in person. You don't HAVE to get this exact bov. There ARE others out there. ;)

EDIT: Tuning session set for this Saturday morning. :)

PETER: Check out this website:

I can buy HKS SSQ for $28.00 & HKS turbo timers for $37.00 in an HKS box with all the proper lables. Trust me the Chinese counterfeit everything. I can even get counterfeit AEM FIC's. Like I said fake or not if it works, its good for you and me.

[PETERPOOP]

I don't think mine is fake.

That fine, no big deal : )

[Tamago]

i'm glad you went turbo :)

[PETERPOOP]

amen to that! i now see the light

[PETERPOOP]

Yup yup. Focus will now be put towards this Saturday's results.

[PETERPOOP]

Ok. Here we go...

WHP: 175.14 TQ: 175.38

Dyno sheet showing current whp/tq with turbo set up in green, and comparing it to old tune with the blitz s/c in blue:





So, this was done on 8lbs of boost. However, the 1zz fuel injectors were maxed out. I need bigger injectors. The tuner got the A/F to a little under 12 AFR. He wants it to be at 11.5 AFR. From that, he can richen up the AFR and maybe get a little more power from it. To sum it up, i'll be getting bigger fuel injectors. How big? Not sure yet, tuner is going to figure it out.

Also, the clutch slipped during the tuning session. Yes, I am still using the stock clutch. Yes, I will now be purchasing a new stage 2 clutch. Not sure which one yet. I might get it from the tuning shop, to give him business and in return, hopefully get a cheaper rate for the labor install. Yes, I will also be getting a LSD put in at the same time.

I will be getting rates from him on how much the clutch/lsd/labor will cost on monday (supposedly).

Probably won't have those installed and retuned until the end of the year, i'd think.

He only charged me $150 for the tuning and dyno usage today. I think he felt bad that I now need a new clutch and fuel injectors. lol. He's a super cool and nice guy though. Glad to be giving him business. :)

let me know if you want help with those parts, all in stock. Max power at 4700 rpm, haven't seen that before. nice torque!

[Focus_Sh1ft]

Nice numbers. You're lucky to have a nice tuner nearby.

What did you tune, just AFRs? You should see some nice additional numbers if you did timing since you're running meth.

Also, I'm kinda surprised by the injectors maxing. I've calced my 1NZs to be good for about 4500 RPMs at 8 psi of boost. It is what it is though

I'm in agreement with Garm as well. Max torque @ 4k-ish is just awesome. Zage chose a great turbo for our cars

[PETERPOOP]

Hey, you guys talking about the torque? If not, you might got it mixed up. Since the two dyno lines intersect each other, it's hard to tell which is which. The one that hits max power at 4500 rpm is the torque. It continues to dip down at 5500 RPM. The HP is the one that peaks at 5500 RPM.

The tuner did the timing also and IDK what else. Ya, he's a good guy. He tunes a lot of cars.

[Yoda]

You think you would be able to raise the boost to 10? I think the stock block should be able to handle it with a really good tune. Then again I haven't really researched our engine that much myself.

[PETERPOOP]

No clue, but I want a little longevity with my engine setup. I won't be doing that. Someone else can be the guinea pig.

[Yoda]

Lol you got me there.When u get my tuning sorted out I will give it a test and see how long it last. Will be getting an additional block too and building that.

[PETERPOOP]

Well if you plan on doing a built motor in the future, you would be perfect for the test. ;)

I would think you could hit 200whp with 10lbs of boost. If not, it would be close, I think.

[cali yaris]

^ I think so too.

[rob323]

The injectors could quite well be getting max'd out cause the fuel pressure system has no reference to manifold pressure in a stock (return-less) fuel system. If you can raise the fuel pressure as boost increases, it would give you substantial headroom in that side of things. The other problem is that the injectors may not be spraying optimally when having to fight against the boost pressure in the manifold.

[Bluevitz-rs]

I just thought of another problem you guys might be having with tunning... the stock fuel pump is a 2 speed unit. I forget exactly how it operates, but it goes something like, "low speed at idle and cruse" and "high speed under acceleration".

If someone has a repair manual, they should be able to confirm this. Because this could be causing the fuel pressure to jump around
