Well I ordered my VIAS block plate on monday... IT WAS HERE THURSDAY!

Aaron is an amazing man! Quality is INSANE!!! Shipping is Out of this world!!!

All around A++!!! Glad i went with his and not some product of of a garage...

Here are some pix of the VIAS Plate..

I also took some pics of my Spacer kit... its been installed for a while.. just never put pics up...

VIas plate took 13 mins total... PIECE OF CAKE!!!!

Anyway..thanks again AARON!!!!

BUY HIS STUFF!!!!!!!!

 

 

Throttle Body Spacer...






Elbow Spacer



Spacer On The Head

 

Yell much?

Good stuff...did you use Permatex Gray as the sealant? All install by yourself?

 

Yes i yell A LOT!!!!

No GREAAAAAAAAAAAAT STUFF!

Yes I used Permatex!

Of course my friend... only way to learn

 

Just waiting for you to fly to cali to help me w/ SSIM... You can meet Dues and Jmsith and A few others if you come out... you can stay w/ me for free...

COME HELP Me w/ SSIM!!!!!!!!!!!

 

...I didn't do the cutting though, I sent it out to have it done and then I just installed the IM myself y0

 

Nice nice. But where is your grounding kit? Of course you have to give us your opinion of how it works. I need some more money LOL

 

Grounding Kit? hahaha Is it worth it LOL...

It works great! I felt a nice gain w/ both of these things done/installed

 

what did it run you to get it cut?

 

Im not kidding LOL...ill pay for some of your gas if you come out

 

Excuse my ingnorance but what is the purpose of that plate?

Can't wait to have my spacer done soon too! ...ordering it very soon.

 

just more airflow with less restriction. Takes away low end torque, but you gain more high end at about 3500-4000 RPMs ... eliminates the butterfly

There are a few threads on it ... try the search button ..

 

The motor runs 40 degrees cooler with the spacers, and adds a little more volume to it. The block off plate simply removes the VIAS because it is essentially useless unless you were to have a switch built-in to activate it.

$90 by KRRZ350...but I would suggest trying it yourself or getting a local shop or something to do it for you...

for what though? lol...you said you did the IMS yourself, so the IM is even less work...pay for half of my ticket though and do I get my own room? lawlz

Low-end isn't really compromised with the block-off plate, just gains in the mid-top end. The SSIM is a different story...

 

No VIAS = midrange loss.

 

got on it a little today and top end feels a little nicer? <<< LOL

no dyno no care ... nmexmax?

 

404: Mid-range loss not found

Maybe on dyno or not significant enough to feel

 

HAAA HAAAAAAAAAA!

WHAT, how did I miss out on this deal. KORWA ZAJEBIE.

Kamski

 

So, should I post th dyno or not?

 

You have one for the 6th gen?

 

It's on my car, but the engine / manifold design is identical.

 

When did u do the dyno and what mods do you have?

 

It was years ago, but i dyno'd with VIAS enabled and disabled, back to back.

At the time of that dyno, all I had was Cattman headers and a JWT POP intake.

 

Picture? where the picture, need to see picture. OY OY OY

 

Pic of the graph?

Dood.. uwant to come out here... ill let you stay w/ me and pay for beer/food

 

very nice. cant wait to order my spacer kit

 

Very interesting dyno. The difference actually looks very minimal across the board except for the small loss. + or - 3whp depending on the rpms. Am I reading it correctly?

 

I don't think you're reading it correctly. It's about 15 ft/lbs and 8-10 hp down low. After 4k ish, it's the same though.

 

So VIAS removal=those numbers?^

 

VIAS system, nothing else (i.e. shelf, etc)

 

So am I just a then or did removing the VIAS plate hurt mid-range by 15whp? I still don't fully understand how to read dyno sheets, so please excuse my youthful ignorance

 

I just removed the VIAS plate and installed Aarons plate and I think the power band delivery is much smoother. WTF did they put that plate in there for, seems like a futal efforts at ACRONYM wars.

"Hey Yogashaki, the toyota has VVTI, honda has VTEC why dont we slap VIAS on there since we already have CVVTC, EBD and variable muffler, we'll be one up on the game."

"Hi FAIVE Yoshimori, maybe Takanokasan will give us raise"

 

I believe nmexmax had the plate still physically inside of the manifold or did you take it out? Because even with it "open" it's still a hindrance to flow. Here's a dyno of a 3.5 Altima with the plate in and out. ONLY difference performance wise is the plate.

That's some good gains.

As you can see there is a big hit to the torque/horsepower but then the gains are pretty damn good.

 

so i am reading it correctly?

It gained 11hp and almost 2lbs of trq?

 

It basically confirms what we already knew. Removing the VIAS assembly will definitely hurt low end power and since you are removing an obstruction, top end power should be gained.

I believe NmexMAX still had the VIAS assembly in there. But it does help show what the optimal release point should be if you want to keep the VIAS.

And thanks 2002AltimateV6 for posting that chart. I've never seen that one before.

Fastmax05, yes, it does gain a lot on top end. But you are going to sacrifice low end performance. It really depends where you spend most of your time racing at. For me, all I care about is the 1/4 mile, so anything below 4K rpm is useless for me since I launch at 3000 and spend the time between 3-4K rpm on the fine line of traction. I spend 90% of my time above 4K rpm, which is where I want to see my power gains.

But for all those that care about partial throttle city driving, the loss of low end power may not be what you are looking for.

I also have not personally done any dyno testing of just the VIAS Removal. But it's still a good possibility I can do this in the coming few months since I have a 2002 Maxima 6spd scheduled for more new product testing. I can probably do some dyno runs while he's here.

 

Aaron, that's a good point you made about partial throttle driving and that's why I switched back to my stock airbox from fujita to regain low end power. I am curious though as to how the VIAS plate would work with a stock airbox and not a CAI. Will there be much low end loss??

 

I would have to say that the low end power loss will still be very similar as in the dyno charts shown above. If you went as far as removing the Fujita CAI just to regain some low end power that was lost, then I will have to say that the VIAS Removal or SSIM is not the mod for you. I would recommend it to those who want to improve their performance above 4K rpm, which should help in 1/4 mile times, which is all that matters to me.

But, I honestly think you would love the NWP Engineering Thermal Intake Spacers we offer. They offer a noticeable gain below 5K rpm without losing any top end power on the VQ35DE.

Aaron, I'm in the 6sp manual and I have not noticed any low end loss with just the VIAS removal.

In regular driving I try to launch the car in the 1200-2000 rpm range depending on hill grade and the TQ is there just like it was before but the power comes on much smoother from 3500 and up.

"regular driving" you launch the car?............
