This product is now listed on our website -


Fits all GM V6 and V8 Trucks from 1996-2004 and all GM GenIII V8 equipped cars from 1998-2004.



Features:
Designed to produce power and torque throughout the RPM range
Increases throttle response
Increases gas mileage
Increases acceleration
Installs in just minutes!
A patent-pending design!
Eliminates the need for a ported throttle-body by smoothing and reshaping the throttle-body entrance to increase the incoming air velocity at each given RPM


Note: Customers with ported throttle-bodies and or smooth tubes, please call us for a custom made version to fit your application.



In Truck applications VR has seen gains of up to 22+ ft/lbs of tire-shredding torque throughout the power curve where you can use it! As tested in a 2004 Silverado 5.3 V8. In LS1 car applications, gains of up to 13 rear wheel HP have been seen (03 C5 Corvette).

The VR velocity stack was designed to reshape the factory throttle-body in order to boost air flow velocity at each given RPM. The overall shape of each VR velocity stack has undergone some of the most intensive airflow research that we have ever done to produce the best overall shape for each engine's airflow requirements. In order to achieve this we:

Created a balanced air stream between the upper and lower portion of the throttle-body blade = more airflow.

We then changed the shape of the entrance to build up a higher velocity charge at each given RPM. This allows the intake charge force in the manifold to be increased = increased throttle response and added torque and power under the curve where you can use it.

Streamlining the intake was also achieved by directing the air in a controlled fashion to reduce any power robbing turbulence over the AIR and PCV valve to maximize the overall efficiency of the factory throttle-body's overall diameter.

Each velocity stack features a varied plenum volume whether in front of the throttle-body or in overall length to help them boost the primary and secondary pressure waves during the cylinder firing process = a tuned and more balanced induction system giving you much better overall combustion efficiency = more power and better gas mileage.

The part number for this product is - vrstack and the price is $49.99.

Hmmmm is it just me or is it kind of funny that the dyno has some spikes in it at the beginning, and the AFRs are all wrong?

Also, the AFR is @ 12:1 and the after is @ 15:1. Do you think leaning the motor out that much might have something to do with the HP gains?

 

I asked VR about this and was told that the A/Fs would straighten out after the computer adjusted.

 

That is exactly my point. I don't see a ported TB, or this doo-dad giving you more than about 1-2 HP if anything. Most folks report a ported TB worth nothing or very little. Yet this little wonder is worth 22HP...

Its just kind of fishy. Fatten the truck up and do a dyno, then pull out tons of fuel and make it so lean it will burn a hole in a piston under any kind of load. Then do "back to back" dynos.

I'm not knocking you for selling their product. Its just that I am a bit skeptical in light of the AFRs that their numbers are slightly skewed.

I think more accurate results might be some dynos where the AFRs are the same, or at least somewhat close...

Well if the product was actually flowwing better then the stock throttle body that would make the car run leaner :yesnod:

 

just ordered one with the vr1b from vararam. we will se what happens. i plan on driving the car for a 100 miles. than go to the dyno i already have before numbers :cheers:

 

Tom, how can they HONESTLY claim a gain from that dyno graph??? :banghead:

Man, the more I look at VR's claims and dyno graphs the more and more I'm thinking of running the other way as far as I can.

 

Poor form to post this thread with those dyno graphs....Surely you aren't blind to how ridiculous they are Tom. Lets see some real results graphs from it.

Is this what the LS1/LS6 vendors are reduced to these days???

That dyno and the Widemouth one are scarey...



I'm REALLY REALLY having doubts about getting a VR-1B now that Vararam (Patrick) finds it OK to try to pass stuff like this on us! :banghead:

 

A few customers have said that they are going to do before and after dyno testing so we'll see how they go. I first saw the Volcity stack on Trucks a few weekends ago and thought it was kind of interesting. A few people called to see if we carried this so it went into the list last week. I have two trucks that I'm going to slide the stack into when our shipment arrives in a few days.

 

I inquired about this item a few weeks ago. It is an interesting concept, but does it really work. I will wait to see some before and after dyno readings from someother than the vendor. I have the Vararam 1-B and it is a great system, so I expect simlar quality and performance from this item.

Their vr1b is FAR FAR FAR less hp than they advertise. They tried to tell me a 25rwhp min increase from a stock filter, 40hp no problem. Yeah, whatever.

 

I'm a little hesitant to purchase from a vendor who can't spell "Velocity" correctly in their own post title :lol: :lol:

 

I was waiting to see if anyone caught that :)

 

Sounds a bit fishy to me.. but, I'm curious to see some customer dyno results. I can't see this making more than a couple hp at most.. Wasn't there also a product that is some sort of spacer for behind the TB as well? Did anyone conclude that it works?

 

oh P-L-E-A-S-E; are they trying to sell this to teenagers?

Looks like a restriction to me.

I dont know about this one, I look forward to the follow ups of real life user posts. Yeahh, me and my wife Morgan Fairchild, could use that torque to get to the snake oil festival faster though. :auto:

 

I run a throttlebody spacer in one of my trucks. Can't say that it adds much hp but the gas mileage did improve.

The info I posted was direct from VaraRam. I did find this quotea bit ove the edge :)
