Good, maybe while you're there YOU can find out why xbg's motor gave up at 5200 and was tuned so lean.

As for anything else I will comment no more.

I'm interested in the tuner's comments.

cali yaris · 01-28-2011, 10:44 AM

^ If you're willing to do that, your dyno would be great information.

Nexus1155 · 01-28-2011, 10:48 AM

Ummmm, all of those values were pretty close in the range of stoich, regardless you do not want that in boost. Let alone, fuel wouldn't cause that lean of a condition when it wasn't lean like that before higher rpm's unless there was another reason for it.

Even quoted from that same website.

Unfortunately many folks we talk to think the stoichiometric air/fuel ratio is where they should set their fuel system at wide open throttle. So we are torn about posting or not posting stoichiometry data because of that potential problem.

cali yaris · 01-28-2011, 10:53 AM

We know the tuner had control over the A/F. I believe that build has pretty big injectors and all the good fuel mods, so it's not a lack of fuel. What we don't know is the why of it.

The only reason I can figure doing pulls at WOT that lean is to get an hp number. But maybe there's another reason -- I keep saying I'm not an expert.

Nexus1155 · 01-28-2011, 11:04 AM

Yeah, but when you are turbo and maxing the turbo to the engines potential. You will get much more power running a more advanced ignition and proper AFR than to just lean it out. If everything really is in order, and the tuner didn't do it then there is another issue. But, my finger points at the tuner because he built the car as well as tuned it.

I do not think it's the turbo though, if it runs out of air at the top end, and the injectors are still injecting at the same constant then it would be rich since not as much air is getting to the engine.

And how would you just disable VVT-i like that? Just unplug the solenoid? ehhhhh? I don't think thats the proper way.

Well Yoda, enjoy your tuning session.

Don't bother asking about my build to Rolo. He won't give out any info on my project. His been part of my build for 5 years and some of the things we have done is known only to us. Like Ive said some things we keep to our selves. All he'll tell you is yes Aras car makes alot of power.

Have fun

Why?

xbgod · 01-28-2011, 07:23 PM

Not interisted in giving out all my details on a forum for others to decide if what I've done is worth the effort. Or if it meets their standard or ajendas. You guys don't get to know everything somethings are just that, private.

Sorry

Scion XB 1NZ-FE Turbo build <----title of thread

I thought the thread was to help others realize what can be done? I'd almost go as far as quoting you and saying you wanted to be a pioneer and help others get to the point you are at and show the world what can be done with this engine.

cali yaris · 01-28-2011, 09:35 PM

Lame, coming from someone who claimed his purpose here was to help out the community by sharing information.

Yoda · 01-28-2011, 09:41 PM

Honestly if he doesnt want share that's his choice. Though I am curious I kno that some builders like to keep certain things under wrap. He built his motor and showed what can be done with it. The why this and that can be up for debate but it's just one of those things. I have meet many people that would not even tell you what they have done or what they have under the hood. This is no different. Happy you got what you wanted out of it and I am hoping I can get my tune really dialed in since I am pushing the limit for my compression ratio. Little room for error.... Lol but I love living on the edge.

cali yaris · 01-28-2011, 09:42 PM

Then don't offer.

I've already been where most are trying to go and I will help others get there.

It's not about me anymore, it's about our whole club and getting everyone their.

I think we can all learn something new from each other since we carry the same motor.

I will post pics and continue with explaining my mods as questions arrise.

etc.

Nexus1155 · 01-28-2011, 10:02 PM

It really does suck as Garm has pointed out that information should be shared. It's not like there needs to be a huge secret behind all of this.

He has listed ALL of the parts he uses so whats just a little more info? I am sure I can go out and bore a block and do some work and make 400+hp. Did you recently see the 4G63 that made 1500hp?

You have that size piping, going into an expansion into a 70mm? TB going into different size piping into a different size flange. Is that good for flow? Even with a race prepped head, if the rest of the system isn't laminar it won't mean much.

We all like to learn from other peoples builds. Even if other people get angry or upset, other people will learn. Whether it be an achievment or a mistake, it's still progression.

Yoda · 01-28-2011, 10:37 PM

I understand what you all are saying but at the end of the day if he dont want to share beyond this point thats up to him. Sux, yes, but i really dont think its even up to him. Probably the builder don't wanna give out any secrets. He might have had the intention of sharing, and he has, but when it came down to this part its hush hush. I can only guess. The important parts of his build have already been shared already so there is knowledge in that. The tune is the most important imo but this is where i see lots of tuners keep a tight lip. Its to protect there business. Its there secret recipe. Kinda like the Big Mac sauce....Ummm Thats yummy lol. I am sure some of you have come across or at least heard of this.
