This great topic started with me saying I can beat anything with a 3.5L in it. Correction though, I can beat anything stock with just a 3.5L in it at 10psi. That's closer . LOL. Great, interesting info in here though. Keep it coming.

 

corrected, lol (sorry i'm bored at work)

 

Very good info I'm learning alot.

 

Nice artistry.

 

No, it's the first thing SC people do before they install. LOL, change that damn pulley size. 7psi feels too damn close to stock.

 

listen kid, don't come in here running your mouth when you have no clue what you are talking about. SR20DEN has already made 262whp WITHOUT aftermarket cams. He is also ran a 12.8 @ 108 still with stock cams. He does peak around 4.5-5k and it does flatline all the way to 7200ish and barely drops off to 7500. I hate when d@mn new guys come in here acting like they know everything when actually they dont know ****.

 

its not my car its SR20DEN's car and yes thats pretty close to what his graph looks like. The car might gain 10 or so whp after 5k but its pretty much a flat line all the way until 7200ish and slowly falls off to 7500. His torque is also a flat line as shown, its all in his mods and how they work together.

I cited Stephen Max strictly to show there isnt much gained before 6k going to a smaller pulley. I should hope he would make more than a NA Maxima considering everything he's done to get to that milestone

It doesn't take rocket science to figure out a 370whp SC'ed Maxima would run around a 260whp NA Maxima but like I said line up a 300whp SC'ed Maxima and they would be door to door or d@mn close at any speeds. Like I've said 4000 times that some of you can't grasp I've ran SR when I was making approx 320whp and didn't pull from him hardly at all, I'd say maybe a car at most running up to some high triple didget speeds. If some of you can't comprehend it Im sorry but it is what it is.

 

Where the hell is SR20DEN, I think he is a made up character.















Maybe that'll get him to chime in.

 

shows how much you know

 

Search his posts if you want to see his numbers. Also he is out of town on business which is why hes not online.

 

....... ........

 

when then I apologize blu...I thougth you were using stephen max as a an example for this entire scenario...didn't realize you were referring to only the comparisons of pullies...in either case, sr is not the norm either which is what we need to keep in mind...in addition, if his powerband truly peaks that early on and keeps it flat all the way through...than I am thoroughly impressed (not being sarcastic)...

 

well smart ***. you are only choosing whats best for you. this guy sr20den is 1 case in a million. i don't know of anybody else running stock cams and 260 whp besides velicos with the eu. but the point is that a regular 3.5 does 240 whp. so you can't base your assumptions on 1 car when the rest of cars are not like that. u want to chose any 300 whp sc 3.0 against a factory freak owned by sr20den.
grow some ***** and compare apples to apples.

 

He is comparing apples to apples, Sr20den has done work to his car just like a person with a sc 3.0 with 300 whp.

 

its just 1 car. did somebody replicate this 260 whp without cams?
300 whp has been done quite a few times lol

 

on 350z's 300whp has been done NA...they have many more NA mods available that we haven't tried out yet...not to mention they start out with much more aggressive cams from the factory among other things such as more aggressive timing and AFR's

 

I don't think anybody has the same setup as sr20den.

 

nobody knows for sure what is the advantage from a z to others like maxima or altima for sure. everybody speculates but don't show proof.
the z's without the revup motor do the smae numbers as a regular maxima or altima with bolt ons. and by the way, i have yet to see an NA z passing the 300whp barrier with proof.

 

Too bad I took the bottle out. It'd be nice to get another run in sometime. Good times......

 

I've seen one with my own eyes on a dynojet 2 months back...and there have been a handful of other from what I have heard...but it took every bolt on in the book to get there I here...

 

i will love to see that myself.

 

Didn't his car dyno something like 198 whp when he first got it? If that's true, I'm not sure you'd call that a factory freak.

We've seen other VQ35 Maximas here with just intake, headers, and exhaust hit 240s N/A easily, so I don't see why you think that 260 is so unattainable, Virg. It just that no one else has really put in the time and work that SR has. And plus, Velicos did it on stock cams too, so that makes 2 of em (even though it seems that he dynoed at CPR, which throws those numbers in doubt).

 

velico's car is always in florida and drove all the way to north carolina to install the eu and dyno. he got those numbers there when it was freaking cold as hell. the numbers were std and when he came back to florida the tune got screwed up so basically he got those numbers only 1 day lol.
My bad, I shouldn't have said factory freak but eventually nobody got those numbers before or after with those mods. and talk about powerband. only vq35 NA with that powerband with stock cams.

 

We already know the difference. It's the intake manifold design, the wider range of advance and retard with the VTC components, and the more aggressive timing maps, especially after 5000 RPM.
What are you talking about? 350Z's dyno in the 230's stock. An N/a FWD 3.5 won't see those numbers without bolt-ons.

 

i dynoed at 245 whp with i/h/e/p and safc2 tuned. i believe 260 is attainable because there is proof with sr20den. But, It's only 1 car out of thousands of maximas and altimas.
What i'm trying to say is that 260 whp vq35 NA won't beat a supercharged 3.0 with 300+ whp. only 1 car has done that type of powerband that he describes and i bet it's going to be VERY VERY difficult to duplicate even by sr20den.

 

I guess you don't understand the part where i say "the z's without the revup motor do the same numbers as a regular maxima or altima with bolt ons"

 

where did you read about the vtc components advancing or retarding more on the z? where is the proof so i can read about it?

 

OK. But what's your point by saying that? Even if a bolt-on 3.5 motor makes the same peak numbers as a stock 350Z, it won't quite hold the power to redline as well as the 350Z.

 

I have not seen a Z even on my350z.com that has gone past the 300whp barrier NA.

you know where is the proof about the vtc?

 

My mistake. I must've read wrong originally. I went back to take a look at the Nissan Technical Paper and it was comparing the 350Z motor to the 2001-2004 Pathfinder 3.5 when it referred to the wider range of VTC movement.

 

I don't want to sound like an azz but all of the differences between the altima and z is guesswork. the only thing we know for sure is timing and intake manifold. even if we tune the altima with the best tuner ever and install bolt ons plus Z intake manifold it doesn't get the same numbers that the z get with bolts ons and tunning. why? i don't know yet.

 

There is one thing that we're still not accounting for....the 350Z VTC maps. Even if they don't have higher VTC adjustment angles, perhaps the 350Z VTC maps were designed with the 350Z intake manifold and straighter-path lower manifold in mind. Different intake manifold design = different intake pulse resonance and the VTC would need to be optimized for that, right? I know for sure that it was a combination of intake manifold design and VTC's that allowed the 350Z motor to acheive 105% VE at 5600 RPM based on the technical paper that i read. I think that's the gap that needs to be bridged. It's plausible, and i can't think of anything else...

 

this is something technosquare can do for you. copy the map for the vtc and timing from a z and flash it in your ecu.
but nobody has done it before?

 

this is rediculous...the Z's start at 230-240whp...and yes there has been a handful of guys with every bolt on imaginable that have hit the magic 300whp with cams...I don't know how to prove it to you, I have seen one of maybe 10 that dynoed right in front of me that hit that....you have to remember that they have many, many NA mods out right now...ones we have haven't even attempted to try out or have made for our cars...

 

To my knowledge there are only 2 users on this site that have successfully installed the 350Z intake manifold and only one of them is using the 3.5 ECU with operational VTC's. He would be the first to try the 350Z VTC maps if that's the route he decided to take.

But once again, i believe that's the difference maker when it comes to bridging the power gap since that's the only variable that's been left out so far.

 

i'm not saying you are lying, just big names like crawford and others didn't reach the 300whp but got close with everything possible.

 

the crawford plenum was actually dynoed a good deal lower than the rev up manifold with these new spacers they came out with....which are much cheaper, and hence a slap in the face to their super expensive manifold...

 

Nobody has larger injectors that increase timing, no one has a 7500 rev limit, no one has a 77mm homemade MAF and only one other guy has his manifold that dynoed.

I guess you can't read that I've already ran SR20DEN and pulled about a car and a half up to 150ish making 322whp SC'ed at the time. Like I said I've done it so I know, Im not just making up stuff to please my opinion. I just don't understand how some of you can't comprehend what Im typing.

 

big names like crawford cars are 100% street legal with cats and every other part needed to pass inspection. Their power made to the wheels could pass inspections in Cali without problem. If they ran the car illegal without cats and a few other tweaks I'd bet they would make 320whp with there setup.

 

For those wondering SR20DEN's car dynoed 201whp stock and was only running low-mid 14's @ 95-96mph with a pop charger only. There is nothing abnormal about his car, it started out exactly the same as any other 5.5 gen. Now he has only made about 60 more whp than stock but with his power band and how the mods work together he is now trapping 108+ with stock cams. The nismo 262's will be going in soon and the car will be ready and running at Maxus if any of you SC'ed guys will be there and want to test my knowledge.
