I’m sure some of you have been following this venture. Looks like they finally got it ‘done’. Or at least installed.

Not especially relative to us, but it is somewhat of a breakthrough. More so for the A34 vs A33B. But, it certainly opens the door for the A33B as well.

Opens the door for quite a few specific cars. I noticed your post on the other forum is incorrect, too: "Since Maximas stopped coming in 5MT since 2004." Shouldn't that be 2001?

 

me = .

Must have been the Altima mood in the air.

 

that thing is CLEAN.. very nice looking.
I'm curious about the feed pipe, can't really see much of it from those pics.

 

glad to see some progress being made

 

That is really great news, they did mention the maximas in their thread. So that brings some hope of seeing a FI kit for the 5.5.

Also I believe SFR did this a while back for someone that used to post here, he had a silver Altima with a bodykit, and had a marines banner on the windshield.

That dyno chart looks like ****... its all over the place.

 

Need to see how/what he's doing/using for FM. I asked the question on the 1st or 2nd page, but I don't think he's answered me just yet.

Jut getting the normal,' ZOMG!!! Nice work!!/Will it fit my *insert tranny/year type here* car?!!11' type of replies/posts in there for the most part.

 

Some ask the same thing in my350 but this was his response:

 

That doesn't that have anything to do with Fuel Management.(AKA, FM)

 

Awww shucks! Looks good. Finally. The dyno graph does have some nasty dips in it but that can be corrected.

 

How?

 

Well for 1 I bet that dip in the middle has somethin' to do with the throttle by wire closing the throttle even if you floor it. Also, I notice they're using stock exhaust manifolds. Better A/F tune. Etc. Plenty of variables.

 

yea, but that was their response on how ****ty the graph was. I hope they release more details about it.

 

02 Altimas have the same software as A33B’s, and I can say for a fact, it’s not the throttle.

Of course I'm sure they can be corrected, but I wonder if he knows that.

 

Like I was telling NmexMAX, I think its the ecu taking back timing. Most 3.0, 3.5's peak tq is at around 4500ish more or less which is close to where this dyno curve drops. So i really think that the setup is causing alot of knocking, its not even intercooled!!

 

Wait, I see a intercooler in the photos and the video. You think they would be running the car like that if it was knocking???

 

look at the dyno and pictures, you do not see an intercooler the filter is in the engine bay directly on the shiny turbo. They probably dont even notice the pinging over the exhaust.

 

I see an intercooler. Air comes in from the filter and then is routed down to the intercooler and from the intercooler to the IM.

 

forget my non intercooled comment

 

The kit does have an intercooler, I talked to Turbo Tim who confirmed it...

 

More info from TurboTim:

"If the guy that has been posting about this on the Maxima.org could copy and paste this over there,that would be great.First off,I cant post on the Maxima board, it says I am trying to edit someons post or I dont have access! What the heck is that about?

Onto the questions.The dip in the curve is what we beleive is the secondary butterfly opening.Both dyno charts have a wierd curve to them and we seen this on the last Altima and Maxima we turboed a few years ago.This turbo is smaller then the full T-4 we used on those earlier turboed cars and the peak torque is coming in really late on both of these newest charts. There was no detonation(knocking)and the air fuel mixtures were good.Right where we want them.The timing was conservative and we pulled a few degrees on the higher boost run.There was nothing out of the ordinary.We will be doing a system for the Maximas so stay tuned for that."

 

The dyno looks like the engine does not like the boost and is trying to protect itself.... Its all over the place.

Also, probably could get more power under the curve if they could smooth that thing out.

 

a bigger IC might help, that IC is mighty small

 

Bigger IC, Technosquare L-Spec flash(7100rpm, WOT-by-wire, no speed limiter), Kinetix IM, IM spacer and whooo hoooo.

 

Aside from the rev & speed limiter, L-spec does nothing else. The KIM will probably finally shine in a boosted app.

 

Did you look that up before you typed that?

Limited Spec (L-SPEC) Flash

Features
- 7100 Rev Limiter (500rpm Increase)
- Speed Limiter Removal
- Drive By Wire Re-mapping
- Stock Fuel, Timing and CVTCS map (no changes)

Do you have the data I have?

 

Maybe. Site your reference if you have somethin' concrete.

 

eng92 has some data listed here: http://forums.maxima.org/showpost.ph...6&postcount=47


That and I have access to a local stock softwared A33B. I conducted my own tests. I also had Elon Hayes send me some TPS data and compared them as well.

Our true TPS data doesn't differ no matter the situation

 

Interesting,
Here's my experience:

If I floor it from a stop it shifts aggressively from 1-2 and from 2-3. But "something" happens in 3rd gear. It almost feels like I'm letting off the gas. After maybe 1.5 seconds the power comes back on again. You can actually hear the power drop and then come back on. Could it be the auto tranny "flash speed"? I always attributed it to the DBW.

Now if I'm just cruising in 3rd gear and floor it the power is instant. Weird.

 

It's the lock-up torque converter doing its job.

http://forums.maxima.org/showpost.ph...6&postcount=16

 

The links are dead. Can you explain?

 

Don't tell me torque lockup is occurring at this time. I thought that happens any time you floor it.

 

All the links show is a couple of dyno curves showing that slight dip. And a speed vs time log as well.

 

And don't tell me; it only happens on autos?

 

Unless you can find a manual with a torque converter.

Only in autos only in 3rd.

 

So what exactly is the TC doing at that point?

 

If you leave it in D or shift to 4th, it wont happen.

My 4th gen did, my 5th gen does it, and I've seen 6th gen dynos that prove it. It's unlocking at that point. Disengaging since you're going into say a high load mode so it unlocks. Locking TC helpes MPG, when it's locked, if you're @ 3k in 3rd, and the shifter is in 3rd (vs D) you're not looking to save MPG.

 

Oh, wow
That's crazy. I wish it wouldn't do that. I've been in a couple of "runs" where it seemed like an eternity before the power came back.
