Block off plates

Postby knight_yyz » Sat Nov 28, 2009 8:09 pm

hey guys, most of you guys with the VQ35's have heard of the VIAS delete, AKA the block off plate. I made up one for Ghost a few days ago and we installed it today. Took a little doing, it is a bit of a pain, as the FSTB has to be removed if you have one, and a few things need to be moved out of the way.

NWP is charging 40 or 60 dollars for his plate, plus 20 shipping, plus customs and taxes. So you are looking at minimum 60 plus 5 dollars charge plus 13% tax, plus install if you are not mechanically inclined.

I'm prepared to make a few of these in the near future for 60 Installed. No fancy logos, no fancy polishing. You will get exactly what is in the pics below. This is the actual picture of ghosts car about 10 minutes after install and test drive.

I'll let Ghost chime in on the performance results, but I have to say it was pretty impressive. IIRC an auto with the pedal to the metal will shift from first at about 4500 RPM. Ghosts car pulled up to about 6200 RPM at WOT and then switches to second gear. Talk about a rush!!

I'm not familiar with this mod at all.

And in my automagic, when I floor it off the line, it up-shifts at around 6200 rpm into 2nd as well.

I haven't read much about this mod since I'm 5.0. But is this essentially the same as us DEK's removing the power rod?

check out the org. lots of information and discussion about it there. I'm suprised with the results when I talked with you. I thought it would have only been really noticeable on a modified car. What has Ghost done so far? Pop charger intake, exhaust adv timing?

This is a lot cheaper than paying US and shipping. Ray has great quality products too, so I'd be interested in one.

Yeah, Ghost has the velocity stack, advanced timing, b-pipe+vibrant axle back. Also, I don't think the auto's shift from 1st to 2nd at 4500 rpms if you floor it, it's shifts almost at 6000 rpms I think.

Well I will say its quit the RUSH, some have expressed a bit of lose on the low end torque to which I say HOGWASH there is no low end lose and there is lots in the middle gain, and well the top end is just over the top. I have to disagree with you a bit Will on the normal up shift at 6200 rpm, If one is on a up hill climb in the road under heavy throttle then yes I have been able to push upwards to 6000 rpm before the auto will up shift. I have done a few runs using the different auto drives such D3 and have had it steadily climb into the mid 6000 range before up shifting and the torque well I am impressed, In normal drive and pushing down on the peddle the engine easily pushed 6200rpm before engaging the up shift. Since I purchased my Max I have pushed it on many occasions as listening to the sound of the VQ roar is most impressive. After adding the intake short ram and timing advance I thought I had a pretty quick car for a mid size family grocery getter, adding the BPI velocity stack and the over size air filter I felt my gawd this car is quick off the line for an auto. I had been reading alot about the VIAS delete and the block plate and well after having it done and feeling the car pull the way it does now I just say WOW this kind of pull I would expect from 2door sport coupe ... but from 4door grocery getter "FANTASTIC" I do believe even Ray was impressed that an auto can get and go the way my Max did for the couple of short runs we did on the local streets and when I hit the HWY weeeeeeeeeehaaaaa can she ever move.

Like any mod everyone will form an opinion and express themselves accordingly to there fellow members, for me, best few mod bucks I spent. very well crafted plate and it delivers just what I was hoping for, a stronger draft of air and strong torque ... I hope to take a couple of short video's tomorrow and will post them up, the sound of the VQ opened up and RPM continuing to build well beyond the normal shift point delivery such power and increase in torque is most impressive. I may be sitting in a heavy 4 door sedan, but she sure pulls and scoots like its a light weight 2door sport car. Thanks again Ray for your machining skills and producing a quality product, that helps to push out every extra horse the VQ is able to deliver.

Can't wait til spring to to add in some NWP spacers and see just how much more power can be had.

I found this link from the .org with a dyno on the curve from the VIAS delete and block plate installed, for those interested.

Yes it is the same thing.


I wasn't aware that the autotragics could shift at 6200 RPM at WOT. Sorry for the misinformation. But removing the VIAS is supposed to lose a few torque at the bottom end and gain about 10 or so horsepower after 3800 RPM up to redline and beyond if you have extended the rev limit.

BTY, I can't bang off ten or 20 of these in a week. I can make one once in a while. So I will start making Nigel's and and then pick away at the list if there is one. This will work on at least an 02 -07 Maxima, and 02-06 Altimas as well, and must not forget about the 02-04 I35's.

Nigel, do you try that experiment I asked you about?

what about us 01s with the VIAS system as well? Any tips on checking if mine is functioning or not? I know when i floor it the revs go to redline in first everytime, is that the check?
Wouldn't mind some extra horses up top thats for sure.

00-01 need to remove the power valve to get the same effect. The 00-01 power valve has a butterfly in all 6 runners of the plenum. The 02+ have one butterfly in the plenum.

Yea, I thought it was too late to call you. With spacers and pop charger intake, it shifted from first to second about 4500rpm at about 90-100km. I'll be heading to milton in a few, and try again to see if I can be more accurate.

Really?! 4500rpm if you floor it off the line? :shock: I just had to youtube some videos cuz it's freezing outside. Both seem to shift at around 6000-6200rpms.

Hey Ghost, interesting info.

I'll WOT my car sometime today (good excuse to :twisted: ) and see where it shifts, then report back. Sometimes if there's a floor mat in the way underneath the accelerator, maybe it limits one's max revs??/ We'll see.

Glad you're happy with the mods. You're definitely making your ride stand out.

Like i said, I'll try it again to be more accurate. it is more like 6000rpm, must have been seeing things.

The block off plate is a good mod for sure. +1 Ghost! The high end output is much better(air flow) without that big butterfly valve in the way. It's for sure that you're going to lose a bit of torque low range, basically less vacuum, but it's hard enough to get the tires to stick WOT anyway! Our cam timing is also mapped to work with the VIAS assembly as well. I have it and I agree it's a great MOD! Ray you should get some "Ray's Engineering" stickers!!
