As you can see, I no longer have a Z. But we should meet up anyway. There is already a club that I'm a part of. It's club SDZ32. Let me know if you're interested. I haven't been in a while, but I intend to next semester more. They meet at miramar speedway. It gets kinda expensive ($20 a race). There's a lot of cool guys that go. We should have a Zdriver meeting though. I'll bring the beat up Supra.

 

Email me your AIM, michael.sesher@navy.mil

 

Lucky ....... I've been looking for your answer. This isn't absolutely conclusive tho.....

This guy says Garrett TB02/22.

btw..... here's a guy that "says" he runs 18 psi.


More info on 10 second Z's

Looking at the above time slips, I'd believe emo.

 

Here's a time slip on that same site (thanks Canyon) of a guy running an 11.6 with pretty much a stock car.
http://www.dragtimes.com/Nissan-300Z...slip-3876.html
I mean, with a little tuning and a lot more mods...at least an ECU upgrade (his says stock), he'd definitely be in the 10s. Then again, it's hard to believe he's still on the stock computer if he's running 18psi of boost. Once again, I never said Charles hit 10s. Last I heard was low 11s and last I saw myself was 11.9. His goal is 10s on stock turbos. I personally think he can do it...even if it takes a little juice to get there. I sent him an email to ask what his fastest time has been yet....he'll probably get back to me in a couple days or so.

 

The funny thing about that link, is that it is the same slip being used by someone on ebay trying to sell some ecu thing, except the guy on ebay is in alabama. Hmmmmm......Something smells fishy??? It is ebay item #

Honestly This thread is another he said she said arguments over the internet. Its rediculous. I believe emo due to the fact that he has over 1500 posts, been here a year and a half, and the mods tend to believe him. Thats good enough for me. Not to mention the fact that he never said that he accomplished it, but rather happened to see some readings. He was simply letting us know what he saw. Now who knows maybe the reading was wrong(electronics have been known to give false info) or maybe he is dyslexic and it was 12 not 21, but does it really matter. I mean honestly. People are so retarded these days(see previous 4 pages of evan). Its like people want to call in an airstrike on someone just because they dont believe them. All evan needed to say was from my experience that would be near impossible to do but oh well, and move on. End of story. Thanks for allowing me to use the z soap box. "Rant OFF".

 

I saw that website earlier today. Those are some impressive times. It's so hard to get the power to the ground in these cars.

Chip Ginn (Of GMS, I believe, right Evan?) appears to have the fastest time on stock turbos. He was running 18 psi using 110 octane. It says stock ECU, but that can't be right.
Mike Mehnert ran 11.98 with intake, exhaust and 100 octane @ 19.5 psi on stock turbos and ECU.
It doesn't look like anyone has gotten close to 10.999 with stock turbos. 11.6 isn't close. I'm not saying it can't be done. If anyone can do it, I would suspect that GMS would be 1st. Notice how Z1's peacemaker isn't on there. 811 HP. They also have that 1000HP monster. Power is one thing,...traction is another.


Emo,what gas was your boy using?

 

Call me stupid, I don't claim to know half what Evan does, how do you increase the psi on our turbos?

 

C16 race gas.....110 octane

 

To increase boost, you either need to install boost jest or a boost controller. You've seen us talk about stock ECU's in this thread. The reason that is a topic is because generally, you need to increase the amount of fuel as you increase boost. This is generally done with the ECU. The factory setting on these cars is 9psi. What that means is that anything over 9psi and the wastegates will open and bleed off the excess boost. Boost controllers do basically the same thing. Once you hit the pre-set amount of boost, the boost controller opens the waste gate to bleed off the excess boost. I think it was canyon carver that said any turbo can produce prety much any amount of boost. You control boost by controlling the wastegates.

 

So what you're saying is there is no adjustment to increase boost like you would say idle.

:doh:

 

Here I know I'm asking for a brow beating again .........

But I'm pretty sure (not positive) alot of the SR guys get pretty high boost levels and h.p. by going to bigger injectors and an SAFC without ecu mods. That is a simplified statement, but 400 h.p. out of those 2 liter engines is pretty common with all stock internals. You can find a wealth of turbo info here:

http://forums.freshalloy.com/ubbthre...at=&Board=UBB9

 

The problem is not high boost levels. Yes you can boost to 21psi on a Z no problem if you have the supporting mods and different turbos. The problem is that the stock turbos are only efficient to 17-18psi or so, any boost level above that point and you are losing power.

Does no one here read compressor maps?


And the stock turbo size is TB22, although it uses a t25 housing.

 

So in conclusion you e-know-it-alls go boost your stock turbos to 21 psi and then post when you blow **** up so i can laugh :rofl:

 

I don't think anyone here wants to boost to 21psi......

 

Or read compressor maps for that matter. They are interesting, 3-dimensional, computer generated, little mountain looking thingys, kinda like in Tron. :rofl:

 

Emo,...I wonder,...if your friend were to turn down the boost a bit, he'd be able to advance the timing more; which would generate more power than running at 21 psi. That is what Evan has been trying to say. Yes, a stock turbo can get to 21 psi, but it is robbing power to get there and not explode. More boost on the stock turbos will not be the way that he gets to 10.999sec. With that 110 octane, what is his timing set at?

 

2nd!2nd!2nd!

 

Can I get an AMEN!!!!

 

Emo sent the video. 11.9 second 1/4 mile. That, along with the drag website, I believe him. 21psi was likely a spike. He's waiting to hear back from Charles to find out what else he's done to the Z.

I think everyone here will back this statement....
It is not recommended to run this much boost on factory turbos. It will severely shorten the life expectancy of them. In order to keep from damaging your engine, be sure you have the right supporting mods. Race gas is also recommended.

This should help
-Completely- stock = no more than 12psi MAX (stock fuel map limitation), 10 psi safely

Ecu upgrade = 15psi max, 14 safely (JWT ecu comes with boost jets set at 14psi setting, ASH comes with boost jets set at 15psi)

Injectors = 15psi safely, 16 max

Intercoolers = 15psi safely, 17 max

And max psi on stock turbos is 19-21psi (depending on who you talk to) but anything over 18 is highly inefficent.

Again, this is just what I've picked up off of posts & threads on this subject.

 

11.9 does not equal low 11s
nor does it equal 10s like emo originally stated

And also its funny how it went from 21psi of boost, to a 21psi boost spike.

 

Drop it. He said Charles want to get it into the 10's. He never said that Charles ran in the 10's. He said he thinks that Charles has run in the low 11's since then.
