Max just in case you and some of the other members missed my last dyno when I was in Florida. Here are the slips. Warren

 

Both of those ideas would cancel out, because SAE sets the table as far as conditions are concerned.

. Not always, as it depends on conditions.

I wouldn't say 27%, that's ungodly high, I agree with Dave B

And you're right, it is faster and will definately feel much faster with the added torque.

 

We all know the the VQ engine series has lots of potential.
In the end The max is not as responsive to Mods as much as the 350z.
The max seriously needs a new plenum, ecu reflash, cam profile, and set a headers.

More gains will be seen with a plenum than headers.
More gains will be seen with a plenum than the intake/exhaust/y-pipe gains you see here.
Gains with just Plenum + Technosquare ECU = godly compared to stock.

With that said, the said gains from the listed mods are disappointing with this Engine. None the less congrats to the thread poster as you did very well under the circumstances presented. btw I think your car might have been slightly heat soaked. I'd go do a run with her cooled down.

Of course my Max is going away and in my arms is a Z06 but I had and started to mod a 350z before the Max (which got sold back cause it was a pos). In that time it was pretty obvious what made the most gains on this engine to me. And thats pretty much the entire top end.

You guys should make much more noise and demand someone R&D these two options. You won't see a serious 350z without these mods, why shouldn't you Maxima guys either?

The intake plenum and ECU are holding back the power way to much.

The problem is no one is making any of these items for 6th gen. Alot of the members have been connecting these compines and we are not getting back any good reponses.

Everything is for the Z or Altima.

We have to make do with what we can get. Warren

 

[QUOTE=ramberg]That's what I was gonna say as well... when you look at the Z, it's apples and oranges too. Even from Nissan you have like 45 trims with a bunch of "racing inspired" stuff that comes OEM. Nismo makes stuff for them, etc.

With the Maxima you have what's basically one trim (hey, we all know the SE and SL are the same car ) and the only "performance" option is the spoiler...

People out there have the money... the parts are just not available. You're starting to see more stuff for the 6th gen now but even then, we're 3 model years into it and there's still only a handful of intakes and no supercharger...

 

or headers.

 

Injen CAI. That is good stuff. What kind of Greddy exhaust did you have??? The SP2 or Evo II?

 

Explain how so?

How much more radical (fwhp) would you want?


Why cam profile? With the exception of the track edition, the profile is the same. And we have the capability to see 260fwhp with our stock cams.



I beg to differ ...Now way can you see a 25 whp PEAK with just a plenum. My car has a nearly identical Z powercurve. Though it can almost be comparing apples to oranges (RWD 6MT vs FWD 4AT)


I/E/Y are not very beneficial with the FWD VQ3.5
How and why? People are seeing much better gains with SAFC-II or similar device. The only reason I'd get a TS id for the extended rev limiter.



I gained ~35whp from Headers and a POP intake.

 

Yeah, I totally agree about the lack of mods! It's ridiculous!!!!!!!! I think there are a lot of 6th Gen owners out there willing to pay good money for worthwile, quality mods. It's amazing that companies are not responding to the demand. Obviously, Max owners are into this stuff, there's a site dedicated just to Maximas. I mean all we are asking for are headers, maybe a plenum and definitely an ECU upgrade. If they work, the units will sell like hotcakes! They have people on here like me willing to help test it.

I've got the GReddy SPII exhaust regarding your Greddy question. I definitely feel more of a rumble now with the Y-pipe though, it kind of "blurps", sounds and feels like a V8 now. It may be a little much for some people, to be honest. However, I think I'm in need of some new tires. Man, the high performance tires like mine the Toyo T1-S are very sweet, but they don't last long at all. SUCKS! Less than a year on these and for their price, it's ugly......

Anyway, for there not to be nice gains at all sounds unreal. I mean I put in the Injen intake in and I saw how that factory box was like unbelievably restrictive. Now with the Injen intake in the front and the Y-pipe going to the Greddy exhaust, it's almost a clear shot, NO RESTRICTIONS. I think most experts will tell you less restrictions, means more HP. But, that stinkin' ECU is hurting the situation significantly. However, I would like to find out the possibility of fabricating the Injen intake tube so that it could run into the low grill area where tons of air enters constantly, like an intercooler? I'm sure that's wishful thinking....

Hopefully, all of these questions and our HP needs will be answered sometime soon. It gets frustrating to wait and wait! PEACE OUT

 

Bump for Maxdizzle

 

"How much more radical (fwhp) would you want?"
Why do ppl climb huge mountains, why did people putting chargers on Maximas? Why are people putting VQ35 cam grinds in a VQ3? Why is the new Z06 500hp? Why did they put twin turbos in the new saleen? Why did they put a supercharger And a turbo in the VW Golf showed and Germany this week? Why are they actually thinking they can sell that? Why do you have over 7000 posts in this forum? Don't you have something better to do?

" I gained ~35whp from Headers and a POP intake."
And this was on a 6th Gen VQ series motor? Stock ECU? I highly doubt you'll get that hp out of the 6th Gen motor's VQ35. I highly doubt your going to see that kind of hp out of this motor. <--- with just headers and intake

"Why cam profile? Track edition blah blah..."
Are you telling me that the VQ35 in the Max shares both Intake and Exhaust cams on the Z?

" I/E/Y are not very beneficial with the FWD VQ3.5"
Yes, on the stock ECU. I completely agree. Guys are making 420rwhp in out of the box trim on the Z's VQ. Tuning is the key with these series motors. Hence again, there is your potential.

"How and why? People are seeing much better gains with SAFC-II or similar device. The only reason I'd get a TS id for the extended rev limiter."
This is relative, my point is Tuning the ECU is a major key this motor. I guess since the SAFC is soo good we better tell those guys at AEM that their computer is junk. Point is put whatever you want in it but tune the ECU properly.

For anyone who is busy or for whatever reason didn't get my point and missed what I was saying between the lines I seriously believe this motor's top end (heads up) and ECU is holding back huge gains in both N/A and compressed trim.

 

And to clarify, maxdizzle1 you did get some nice gains. I'm really happy you got this far bro. But i'm disappointed in that it didn't give you even MORE hp, and the items holding you back from making 2x more hp gain to the floor are not hard to develop and expensive. For goodness sake the Kenetixs for my 350 was plastic.

 

To resurrenct an old thread to further defend this position, I call
http://forums.maxima.org/showthread....1&page=7&pp=40

Where the topic is trying to achieve 300hp on basic mods. You NmexMAX yourself say:
"I'm almost certain you'll need cams, and that's internal, major or not "

Yes, i agree. Major work. But you need them for 300 hp huh, to use your own words, you almost certainly do.

 

Let me clarify ... All my discussions are based on N/A, no F/I.. so....

300 whp is different than 300 chp. Our barrier seems to lie within the 270-280 whp realm, so far w/ stock grinds. 300 whp will need cams, and besides where did the 300 whp figure come into play? I specifically stated 260whp is achievable with stock grinds, and that would be good enough for me ... My point is, cams, for me, would come when all other aspects, specifically bolt ons & IM flow are at their limit, but that's debatable just like anything else.

No this was on a 5.5 gen 2003 maxima automatic, and with the 04, it should be easier. My proof is in the dyno forums. All I have is I/H/17* (which i do not think it(17*) adds any peak, just better response IMO)


Hopefully this is in th works from TS ...

Lobes yes, timing no, or at least has yet to proven otherwise. Check the other forums, they have OEM Cam specs/geometery etc.

But the 260fwhp was achieved on a 5.5g VQ35, and it's different than the 04+ VQ35 .. (04+ have VQ40DE heads)
.


It seems as if you have something maybe psronal, I'm just stating what I know, and it's relation to what you've stated, no need for this, let's keep it technical..

 

Sorry about my comments, they were un called for.

 

Its so nice to see a thread not get taken to the extreme; I.E. Poll:Which Intake? Good on you all for keeping it clean thus far.

 

as always, dave b is spreading the truth ! also good work on that 6th gen

 

get subaru legacy gt if u wanna mod

 

So I guess your Max is stock and you are going to keep it that way.
