Ok, well what with all the talk about the VaraRam King Cobra intake and all. It got me thinking about the Velocity Stack. I have read posts on here and abroad about how wonderful it is and then some stating what a piece of crap. Many of you are on the line like me about whether or not it will work. Well, I ordered one yesterday, I mean its only 49 bucks anyways, not gonna break the bank. But I was lookin at old posts yesterday, trying to decide to buy one or not. Many of you thought that it might work, I know that tbyrne seems to think it is a good product. One in particular stated that it sort of defeats the purpose of porting out the Throttle Body, which is true, it does. This might be a stupid question, but here goes. Does porting the Throttle body actually help? I mean, I have gotten so many responses that the aftermarket MAF's don't work, they flow fine. I have also gotten about the same amount of responses that the factory throttle body flows fine up until about 500 +/- horses. So what does porting the TB out actually do? I was originally going to get the larger bore TB, but everyone said the stocker is ok. With this theory, the VaraRam Velocity Stack might actually work, mind you, I'm not holding my breath or expecting the miracle cure for added HP. But I'm gonna try it and I'll let you guys know what I think. Just thought I'd try to answer some of my questions here.

yah thanks for trying that because i've been wondering about that for awhile

Ok, well, I ordered my Velocity Stack like monday or tuesday of last week. It came in Friday to my work about 5 minutes before I left for the day. UPS just barely queaked that delivery in. It was an aweful small box, and weighed next to nothing. So I went home in anticipation of installing this thing. Open the box, what is this? Now before I go off on a tangent here. Let me say, the fit and finish of this product leaves a lot ( A LOT) to be desired. Cheap plastic molded, flexible and somewhat flimsy. They paint a white mark Top Dead Center with white paint to indicate the direction to insert into the TB. By this time my doubts that this will do anything are greatly increased. But what the hell right? So I go out and install it. Run the truck for a bit and then run into the house to get my wallet for a quick run down to my favorite mod testing area, put it in gear, and believe it or not, I could feel a bit of a difference. Now granted, it wasn't like a wow, this is great type of diff, but a definite gain.

It felt like acceleration, in both normal and WOT conditions were much, much smoother. Throttle response was definitely improved, just a quick tap of the toe and it responds quicker. I haven't really noticed any sort of gas mileage gains like the claims, nor do I think that there has been any large amount of horsepower improvements, but overall driveability and throttle response feels much better. Actually I gased it a few times early on though and low end torque did feel much better and it wanted to go pretty good. I think that it has helped, even if just a little bit throughout the powerband.

I have no before or after number or dyno numbers to back anything up here, just stating seat of the pants notices here. It may not be worth the money, but I did see some gains here. All in all, I am glad that I tried it. It also prompted me to de-screen my maf which I had not intended to do, but I figured if the Velocity Stack is smoothing the air out upon entering the TB, why not. I ran my 2000 Trans Am for 2.5 years with no problem with the de-screened maf so why not. Even better throttle response yet.

I am not telling anyone out here to go and buy a velocity stack, don't want people mad at me because they think its a waste of money or cheap plastic crap. This is just to state what I have noticed, I was a guinee pig and I'd probably do it again. Make up your own mind if you want one.

well in my opinion a ported tb is a big help. the inlet will stay the same. 75mm. what they are doing is cutting away the rough edges making it a smooth bore for air to come in the intake.i believe that the vararam smoothes the very same thing out but it is smaller.

Ok, I originally stated on here that I hadn't noticed any sort of gas mileage gains from the Velocity Stack install, this was mostly from the fact that I hadn't gotten to drive the truck much on highway speeds at that point. Well, I am happy to claim that I have noticed almost a full 1 mile per gallon increase at this point on my gas mileage since installing the VS. I had lost about 2-2.5 mpg after I switched from 3.42 to 3.90 gears, so this has made up at least part of the difference. I think it will get better, cause a good portion of the driving that I have done on this current tank of gas has been city driving. Just thought I'd share this with the group.

Thanks for trying thsi out for us, I might get one since it's so cheap .. couldn't hurt .. I already have a K&N and Flowmasters. My truck, will not spin a tire (unless its wet) .. so since this thing is supposed to add low-end torque, I might get something out of it. :rocking:

 

[L33Z71]

Yeah, like I said, it has maybe helped a little bit in the performance department. Don't think that you are going to add this though and be able to liquify the tires though. It ain't gonna happen. It is a minimal performance gain at best, I noticed a little greater throttle response and a little low end power. I can say though that my mileage has gone up quite a bit. When I keep my foot out of the motor, which isn't often I might add, I have gained a great deal of mileage. The tank before last, right after I installed the vr stack, I got 16.8 mpg, then the last tank, driving it somewhat sensibly, I got 19.8 mpg. Thats a 3 mpg increase. Granted, my mileage on this tank is not that good, but I have been driving it harder too. I am sitting at about 17.5 mpg, and all of these figures are taken off of the drivers info center, Which I have found to be fairly close to the way I used to figure gas mileage. So, I think for the money it was a pretty good mod. Just don't expect miracles from it.

So you think this would be better than a ported stock TB? :think:

 

[Z71Edge]

Hey guys, I ordered one of these over a weekend and it just got it today. After putting it in, I drove around for about 15 min. or so...that way the computer could get the air/fuel ratio adjusted. I must say, I do notice a more "smoother" feeling accelaration than what it was before. Cruising at 60, I punched it to see if i noticed anything different. Seemed like the bog from the downshift was a little quicker and more responsive. Haven't got a chance to really notice any gas mileage increase but im sure there is a slight bit of an increase. Anyways, I just figured i would put my 2 cents in about it. I definently think its worth the $49 :rocking:.

 

[L33Z71]

Eric,

I can't really say whether or not it would be better than a ported TB or not, I have never done the porting of the TB. My main thing started out as a question. I had heard guys say that there is no need to go with a BBK 80 MM TB unit because the stock unit flows enough CFM for the motor. Well, if this is indeed true, what is the point of porting it out? Other than smoothing the airflow out that is? I don't really think one or the other is better than the other, probably get about the same results, its just what you would rather do.

 

[Hit Man X]

Well the inlet to the stock intake is like that 77mm or whatever and so is the TB. The 80mm (unless mad cheap) isn't a good buy...you won't gain anything with it worth writing home about.

The premise of porting this TB is to remove casting flash, to be rid of that ridge by the entrance of the bore, and make certain the blade opens 90° fully. lol

Hell, I think I talked myself into one right there as opposed to the Vararam VS! :anitoof:
