instead of "get the car rolling/moving".........."launch" seems more appropriate and fun.

LOL, thats cause the guy in the 350z was givin me the thumbs up while pointing to his ear. So I played some more FWD VQ35 music for him.

Chart in post #25 shows those gains right at the beginning around 3500-3700rpm.
Chart in post #34 shows about the same thing, a gain at 3500rpm.

I guess I don't see the low end loss in either dyno but Aaron make a good point about launching at a higher rpm for 1/4. I dont know if guys are launching like that on the street.

I have heard several people say that you can't notice the loss in torque the VIAS Removal and SSIM gives you when you have a 6spd. Most don't notice much in an automatic.

Sorry for the lateness, but yes, the plate was physically in there and the only thing gone was the VIAS system, plate was still in there.

Thanks. So the dyno chart you posted only shows the loss in low end power. It will not show the gain in top end power you will get from actually removing the VIAS assembly.

Thank for clearing that up. I just wanted to clarify that for those that may be reading.

I guess I don't see it? Help a chart newbie out ?

The red line is stock. The blue line is the VIAS assembly removed. Look right at 3800 rpm on this chart. Below 3800rpm, that's when you lose HP. But from 3800 rpm all the way until redline, you will gain HP.

And lost power on the low end.

Could the the intake spacers will bump up the torque enough to negate the bottom end loss without affecting the top end gains by removing the VAIS and shelf.

Aaron92SE

iTrader: (128)

The spacers will definitely help low end and midrange power without sacrificing any top end. Everybody who's installed the Intake Spacers along with their Removed VIAS, SSIM, or Kinetix has had good results.

Doh! I was reading them backwards. Thanks

The only thing I did between runs was unplug the VIAS electronic switch.

Removing the plate seems to add a little bit of top end, and removing the shelf and everything else REALLY improves the top end. If you're going as far as to remove the VIAS system function (removing VIAS plate) might as well go big and remove the entire shelf.

Aaron92SE

iTrader: (128)

I totally agree! If you are going to remove the VIAS, removing the shelf along with it is definitely the best way to go.

I really thought we'd be able to offer the SSIM to our customers, but the costs are just too high. I was going to have the entire shelf removed by a CNC end mill and have a flawless cut. It would look exactly like it came this way from the factory. The VIAS area is already machined with an end mill straight from the factory. We would be able to continue this edge all the way down. This would truly be a beautiful cut.

But I wasn't able to get the 'per unit' costs low enough after everything is setup and programmed. Right now, if I offered it, it would cost about $300 (not including core charge of $100) and I don't think people would like that.

One thing I noticed when taking the VIAS out was the entire VIAS assembly is probably 25% bigger than just the portion that flips open/closed. So it seems like with the VIAS out you'd get even more air flow versus simply disconnecting it...just my 2 cents.

Aaron92SE

iTrader: (128)

Yes, this is definitely the case. We are not disputing that fact. Removing the entire VIAS assembly will definitely help top end power.

The only thing that NmexMAX's dyno chart shows is the loss you may see with the removal of the VIAS assembly. But it will not show the top end power gain you'll get.

NmexMAX

No assembly was removed, only the actuation, so all pieces that came from the factory are still in there in those dynos, the only thing disabled was the actuation f the electronic actuator.


Not sure how many of you have seen this:

Yeah, Hilbe, did you show me some pics on that? If so, can you post them here?
NMexMax thanks for that link!

Stolen from the other .org:



Left is a 2004 VIAS, right is a 2006 VIAS.

Easier to hack. I noticed the plastic assembly in the Altima SE-R and 06-07 Max.

On the 07 Max, it also looks as if the entire UIM is plastic.
