My 2000 Max SE Auto Dyno results.....

...Would have been the first mod i did had i done the research and found out it wouldnt throw a code on the cali model.My end goal is to try to reach the whp/trq of a stock 5.5 gen auto. Which I guess is around 205whp. IF possible I'd LOVE to put down what a stock 5.5 Manual does. I guess somewhere in the 215 ballpark? That would be sick. But also a stretch for HP..Maybe I can get the torque there.....
What about YPIPE and Tune? *crosses fingers* I might be able to reach an AUTO 5.5....

Maybe possible if at 177hp and the y gives you that whole 10hp, would be 187hp, and sure with a Tune should be able to squeeze another 12plus out of her.

That would be pretty stout. The trq would be through the roof. Id have to add some cars to the kill list!

I was going to say, a VAFC for his car is perfect for adjusting when his VIAS opens...and also on his car, most HP gains come from replacing the Y-Pipe, whereas the 3.5 gains the most from replacing headers. Just pull the trigger on a y pipe and then wonder why you ever waited so long. Y pipe will NOT hurt your torque
1. he doesn't need to adjust the VIAS.
2. most HP gains come from replacing the y pipe on a 4th gen
3. 5th AND 5.5 gens gain the most from replacing headers. This is because the 5th/5.5 gens precats are not on the y pipe, whereas the 4th gen precats are in the y pipe (except for 99 cali spec - those are just like the 5/5.5gens).

A few things.

On the YPIPE thing you are unfortunately wrong
. The YPIPE for the 2000-2001 Fed spec maximas replaces BOTH of the precats (which are built into the stock y pipe). The YPIPE for the 99-01 CALI spec maximas (mine) replaces 1 of the two precats, and also the nasty ugly junction spot. One of the precats is built into the stock y pipe. The other is bolted on. It retains one of these in order to not throw any CEL.FED

In fact, gut your VIAS, remove the rod, and get headers. y-pipe wont give you much, headers are where the real gains are.
Controlling a VI is old school and doesn't benefit as it used to, or so we "thought" it was benefiting. Also, it's more in tune (no pun intended) to MEVI users, not 00-01 VI's.
And sure, you might argue it wont help peak HP, but make your curve smooth, uninterrupted, more area under the curve, etc. But really, you'd net better gains by using the T&E towards something else, like AFC MAF scaling, and street tuning your AFR.
I'd rather have easy MAF scaling ability than VIAS activation point capability.
Decent hearders go for a price that's so close to a y-pipe, it be unsmart to go with it vs headers.

So nobody is opening their VI earlier?

I guess I didnt account for the fact that I swapped on the 00VI, so I needed the VAFC to actually open it. It's been awhile since then, so NmexMax is probably your best source. I was just throwing in my .02 based on my experience with it. I could still use that VB any time NmexMax

As far as the VIAS opened all the time......is this a hard mod #1.....and #2....will it kill either low end torque or gas mileage? Something has to suffer...it always does

Finally... Bold dek guys dynoing lol... Maybe ill do a for shyts n giggles pull....
Intake
Headers
Lw pulley
Lw flywheel
Test pipe
Ecu with adjusted timing...
5mt ae... My afrs are even more rich than yours lol

This is what I heard. I have a borderline genius friend....lets put it this way...he's building his own plane...from scratch....in his garage.....correctly. He used to build cars and had a 10 second rx-7.....he said dont mess with the vias making it on all the time..... It will run like **** if you do..
I trust him..lol.
I mean why not?! Im puttin down respectable numbers!

If people on here really like that....uh...then...why dont they go VTEC?

I have a manual and still, don't wanna mess with VIAS... but just because u make a RX-7 run 10 seconds doesn't necessarily means you know whats best for a maxima... I do agree with what hes saying though
to be honest... the DEK has Honda like characteristics, other than Nissan calling it a VIAS is really the only difference lol

Certain technologys and scenarios span across the board. The name brand is irrelivant

I think this is correct.. the few 5mt's I see dyno get those tq numbers pretty much stock so for a lightly auto to match those numbers I def think so... I think the whp numbers are in the give or take areas where I can understand some saying too low, o.k or whatever..

Yeah doesn't VTEC have lift...like Toyotas VVTI-L?

For autos, at least for me, dynoing in 2nd gives lower torque and tends to peak later in the RPM band than 3rd.

I don't think dynoing in second would be closest to that 1:1 gear ratio they look for for accurate dyno numbers. Third or 4th I would think.....

3rd seems best, but I've used 2nd in the past.

you guys ****tin on the vafc lol... on an auto with no rev extension opening the vi at like 4400 rpm is good, thats just about where every gear drops to. This wouldn't Give him Any extra power but it'll be more useable on the strip and actual everyday wot acceleration.

Im gonna toss a Y pipe on there and dyno.....then probably a VAFC later in the game......not sure if I'll have the VIAS kick in maybe closer to 3k instead of 3.5k to give it a bit of a boost.
As far as the throttle cut....yep super annoying. I have the writeup on how to kill or add a switch to the speed limiter...maybe its something I'll do when they have to break out the harness for the VAFC anyway. I just dont go over 120 enough to bother with that mod right now..lol

I wouldn't bother with it, since having the VI switch to the short runners is inefficient for the engine at that RPM. Factory engagement is around 5,000; according to the FSM.

Hmmm....when I first saw it I figured it was actually the dyno guy back off on the throttle at first so it wouldnt downshift.......then pushing it all the way in....
I got thrown off by your post. I didnt even see the spike up at high rpms..I thought you meant that big old spike in the middle...

everybody keep saying go Y-pipe, but i'd say go the whole header/y setup... more power and just a y on the 3.0 doesn't sound good IMO...
i need to find a dynojet like tht 1 lol
