I love this thread now. It just got way better with Jamie v. Turbo Heads.

I agree with Jamie... So what does that make me?

LOL

I made better peak with a RR head. I used VET setups to make broader power bands.

So thats another thing.

Im not dissagreeing with you on anything. I think its just safer to say the VET cams will be more reliable, easier to tune for more power without having backpressure issues and also allow him to up the boost more if he wants again without running into problems.

Detonation likes to occur at peak torque for the most part that is known especially with crappy flowing setups.

So we can agree on some things and 20ve cams can work, he just needs to focus on more topend power than mid range. He is just not gonna get the midrange he is looking for without problems with those 20ve cams. VE is all about topend anyways. lol.

Im definitely not against anyone on here lol. There's just some things I feel strongly about, especially doing it over and over multiple times.

Everyone has valid points I think we just disagree with certain things.

In Coheed's case, his elevation, temps and other external factors will affect his setup more than it will Vadim's and others out this way.

I will try to dig up some old sheets tonight when I get to the dyno. Maybe Dave and others have their sheets and can share to save me the hassle.

Vadim knows how I feel about what he should do, a lot of folks would disagree but a precipice will be reached, soon.

For the record, I agree with what Keo just recently said but that just proves that I am a stalker.

My Elevation is 1,300ft above sea level. While it is quite a bit, I haven't seen any real power loss issues due to this (My sludgemonster made 124whp to the wheels at this elevation)

First of all I should mention that I'm using the best tools available for tuning a B13 ECU: TunerCode, tune built from OEM tune, not touching the K value at all. The car runs great on low cams, very torque, gets very good gas mileage (up to 34mpg so far on the highway). Before this thread the car was slow, so slow that my NA p11 felt faster. After I started ignoring the false knocks and adding more timing did the car start driving much better.

Don't get me wrong, the car is not slow. It's fairly fast, maybe even as fast as my 230whp 2600lb Sentra was. Here I'm working with 3000lb though. But when the VVL kicks in, I feel no real difference that everyone spoke of when their VVL kicked in. I would get really bad sputter when high cams would kick in, figured that's the gap being to big thus I gapped my plugs down to .022 and now it seems fine (I am side gapped).

I've tested 3500-5000 RPM switch points no no real difference. I haven't tried 6,000 yet, which I will after the slim fans are installed. As I posted the other day, I didn't even notice my MSD being disconnected from the solenoids, and I wondered on why the car felt faster, and why I didn't hear and audible switch.

Did he log where he was getting knock on the high cam? It would be nice to plot AFR/TQ at that point while looking at the timing map.

Back pressure is one issue, I do agree. But that is not what is stopping him from his power goal. It has been done.

All I can say.


I saw most knock starting at 0 psi, my low end had too much timing thus I detuned it. Then the knock I'm seeing now is mainly at 4000-4800. Anything about 4800 is not logged, thus it's hard to say. Full boost on the tach is around 5k, but from datalogs it looks around 4800.

To clarify, I solely meant this post....
