how do you know if the VIAS isn't working and why would it die after 60K?

 

Hahaha...i was just thinking the same thing. They're talking about this massive top-end when every bolt-on VE dyno I've seen drops off on the top end like the USIM VQ does just a few hundred RPM later.

One more thing, IIRC the 4th gen, when first released, outgripped and outslalomed the 3rd gen SE stock for stock despite the apparent downgrade to a MLB setup. Lemme look it up to be sure...

 

I own a 3rd and 4th gen.

Im my opinion I think the 4th gen auto would beat the 3rd gen auto. No doubts in my mind.

With my 3rd gen 5spd I stomped a 3rd gen auto. My 4th gen auto would beat my 3rd gen 5spd. Soo....you be the judge.

 

VIAS is a plastic design, there is a plastic cup and arm that engages the closing and opening of the high RPM "short" runners. After its been opening too many times the cup breaks off and the VIAS is eighter stuck in HIGH RPM mode or low RPM mode. If its stuck in the low RPM mode top end will drastically diminish and it will feel slower on top end than a VG powered Maxima, where if the HIGH RPM mode was stuck, low end torque would greatly be reduced. There is a design flaw in the DE-K VIAS, and most of the Maxima owners have fixed theirs with JB weld, mine has 100K hard miles on it and the intake is stuck on low end power only, after 5K RPMs my engine pulls but struggles. It will still out pull a stock 5spd 5th gen without a problem, but on a highway it would be very tricky. BTW stock DE-Ks have been known to put out 195WHP-199WHP in some cases. Check around and see

 

Can't we all just... get along?

 

Dyno chart in WHP for a naturally aspirated SR20VE with AEBS header, 3" exhaust, K&N intake and JWT cam gears, ECU. No turbos here, 170lbs of TQ at the wheels with 212WHP. NEO VVL technology allows it to make over 100HP per liter, and Nismo is testing it out on the VQ35DE right now. With good results it shouldn't be a problem with seeing 350-400HP from a NA 3.5L. Redline of 8500RPMs

 

Hey I'll go, at 150 my steering wasn't shaking at all and I expected it to feel scary, but I do have pretty much everything replaced suspension wise. I don't know if I have the best 3rd gen but I do have good compression and 95k miles. JTMax03 is my best friend he's been with me in everything I've done with my car and I've been with him in everything he's done with his car, Shawn I don't have a fan club.

The top end on a VE 5-speed is good, I mean JTmax03 had a 4th gen and 3.5 5th gen (both Auto) and we raced and the 4th gen modded (y-pipe, exhaust, intake and pulley) at the line he could gain on me but on highway it was a different story. The 3.5 5th gen also, off the line it would leave me by a lot but when racing at high end it was more interesting, even and he never took it to the limit so I really can't say that I was faster than him at high end. I don't like to take off too hard off the line I feel bad for the drivetrain, thats why I always usually speed on the highway, I feel bad for the tranny.

No one is saying that one maxima is better than the other, just that every maxima has something about it thats good and something that is bad. I say lets drop this and lets go hunt some f-in Honda's .

 

screw hondas..i wanna smoke an EVO.
actually my goal is to beat a Z06 vette from a roll...thats me boosted though..pipe dreams? we'll let the snail decide.

 

Yes, Motortrend pointed that out in their first test But then Car and Driver had a long-term 95SE that scored a terrible .73g IIRC on there skid-pad so there must have been differences in tires used.

I think I'm the only VE owner who posted about the VE dropping off the powerband after 5,700rpms. It doesn't posses great top-end charge all the way to redline, but it seems to still "feel" like it has forward charge even at 3rd gear@100+mph well into the rev limiter.

 

my 3rd gear redlined i'm at 105mph

 

I miss these types of threads....

 

Dave B. Interesting you Choose Lordrandel's dyno sheet. He's VIS wasn't working that day.
Here is my dyno. copy/paste. You don't see mine dying that soon.

Am I missing something? Your plot shows the same thing as Lordrandel's plot. Yours peaks at ~5700rpms (175whp) and then drops to ~150whp at 6500rpms or a drop of around 15-16%. Your car is making more power than his, but it looks like you do have modifications. Regardless, I'm still seeing the VE peak out at 5700rpms and then the power plummenting. Lordrandels powercurve looks more dramatic because of the scale.

 

The VE's power doesn't plummet nearly as much as a VQ does. I've driven both. The VQ is one torqey engine. But the lack of VI and VTC assemblies hinder higher rpm running.

 

Doesn't the 3rd gen with VE weigh at least 100 lbs more than the 4th gen, due in part to the iron block?

 

the only thing I think the VG trumps over both VQ and VE motors is it's very low-end torque... I like being in 2nd (or 3rd) at 1700-2000 rpm and mashing the throttle and getting thrown back. However light that throwing sensation is, it's still stronger than the DOHC motors. Driving shawns car, I didn't get that *Let's GO!* feeling until 3000-3500 rpms.

Plus... the intake sound the VG motor makes at WOT... MUCH better than the DOHC motors...

 

wow. are we still argueing about this? haha

 

wait till after teh UDP and y-pipe

I wont ever get my keys back

 

Looks like I'm still playing with 175-ish hp at 6300 rpm

My 160k VE 5spd

 

you forgot to say after a long drive in didnt you say 90* weather and with a bad knock sensor?

 

30 minute drive in incredible heat, with bad knock-sensor 'heat soak'

But then again, I didnt wanna sound like a whiney 3rd genner with something to prove so I didnt mention it

 

sounds like the klowns

 

dude your HP looks like it peaked 5300rpm. at redline you have 148HP.

here is my 4th gen dyno. Pay close attention to the Nice smoothe TQ curve VQ baby

 

That proves it right there. Look how much the VQ power drops off after 5500rpm and look how much the VE power drops off after 5500rpm. It obviously is still making some decent power in the high rpm range.

 

I just read this whole thead and now i'm gonna get dressed and go to town and find a honda to whip!

 

No, you're confusing the lines

 

That's torque dude...

 

This is the first ever VE dyno I've seen showing upper rpm breathing that emmulates the MEVI. That looks exactly like my MEVI dyno plot, in terms of shape, peaks, valley, and rpm. I've seen 7 VE dynos (even Bryan Hs) and none of them have shown this. Either most of the VEs have serious tuning problems or this VE is a total rarity. Now if I saw all the VEs showing this type of high rpm breathing, I'd totally believe they posses better 70+mph acceleration than a VQ30DE....but not a VQ30DE with the MEVI/JWT ECU. You're making 175whp at 6500rpms where as we're making 190-195whp

 

Why is there such a difference in curve with James and Jeff's dyno after 5.5K?

 

I'm as confused as you are.

 

my mistake opps

 

functional VTC?? dont give me that "it only affects low end" BS. someone was shooting off how the difference between good and bad VTC is something like 12hp top end along with obvious low end differences.
ahh i cant wait to get my VE dyno'ed! even though i know i'm in for a big disappointment

 

1. It's called a power valve, or variable intake if you like (although it isnt very variable, just open and closed). It is USDM because Nissan loves us

2. Our Power Valve does NOT operate the same as a MEVI, and the statement above assumes that the auto upper intake manifold has 2 seperate runners shortly after the throttle body.

3. A modified VE (and VG IMHO) intake manifold will produce massive top end gains. No I cannot explain it, as a promised a member producing these that I wouldn't. Also the VE does not have aftermarket cams avaliable, but I'm sure if it did, it would produce better results (in terms of daily driveability and power).

 

because not all cars are created equal. I'm sure if Jeff or Red92MaxSE hopped on a dyno today they would produce similiar results.

 

VTC's effect high end, if they are grounded they will skew the curve, same if they are not functioning (therefore retarding the cam timing).

edit: I'm saying that for people who dont know, I know you know.

 

VTCs > MEVI

 

I need to get mine on a dyno. For some reason, it seems incredibly strong compared to my stock engine. Maybe it's just the new knock sensor

 

OMG you wanna get together and dyno sometime?!

 

i should really consider dynoing mine as soon as i get some break in miles on the new motor... with new KS and functioning VTCs then well start comparing


forgot to mention another little feature... VEs have a locking diff tranny and 4th gens have an open

 

oh the things we take for granted

you should get on AIM and join our 3rd gen gangbang
