Vararam Ram Air V

[Mindz]

Think about driving down the freeway and opening your window.

Notice the air comes in and you can feel it on your face.

Now Cut a hole in your windshield the size of your door window.

Notice you have a lot more air hitting you in the face and harder.

Basically, the faster you go, the more air is pushed into the intake (kinda but not sorta forced induction i.e. supercharger/Turbocharger). It's called a ram air intake because you're ramming your car into the air and forcing air into the pipe, not sucking the air through a straw that's bent sideways.

Perfect explanation Mindz

That's what a dyno fan is for.

ahhh thats not the same, unless you have a fan that can produce pressurized air.

Yes, the debates about Vararam go on constantly over at the corvette forum. Before you buy one go over and read them for yourselves. Guys pulling them off after a while and are really upset with the lack of quality and crappy filter sealing, dirt bypassing the filter and dirtying the MAF screen.

Having said that, the idea is to get the lowest IAT(inlet air temp) possible while at a stop for launch. The computer will not pull back the timing as much with cooler IAT. After launch and going through the 1320, the forced ram air effect is supposed to be worth extra power in terms of manifold pressure and lower IAT.

Word seems to be that Vararam is good for performance, but needs help in the quality, form and fit. Not trying to convince either way........

I'll be watching this product for sure.

Should be interesting to see what they come up with. I was never a fan of CAI, and I still do not buy the fact that you can "Close off a section under the hood where all the heat gets produced and pick up COLD AIR. If the stock airbox picks up air from under the car, that has to be better. I bet most , if any, of the gains come from the less restrictive Cone filters they use. But what does that do to the engine if the air filter let's in too much dirt over time.

Here was dyno testing on a stock G8...
Base HP - 309hp TQ - 321
VR and Tune
346 HP, 358 TQ (+37 HP, +37 TQ)

Look at the front of the airbox and you can see a very small hole, maybe 4 inches if that where the factory gets air by the headlight.

I can't agree with you more. I do hope VaraRam can overcome some of the fit and finish issues though. Either way I'll likely go with one.

Dam, that is awesome considering ARH picked only 13 more HP with headers and a tune. At $370 that is a dam good invetment.

You guys are going to be quite impressed with this unit from fit, finsh to its performance, We Know what the Camaro is to everyone and we are putting in heavy testing mileage in hot conditions etc.. . We currently have one car running through West Texas to Arizona running HP tunners dataloging intake temps and airflow rates etc..

We are doing this to ensure quality and reliability , we "WILL NOT" rush out any VR system to get something to market, thats not our way.


We have Green filter USA running flat out to produce the new Camaro filter with our base.

We will be testing some tweaks to the aero package this week as well, if they work and show up in real world testing as measurable gains then they will go into the unit, if not, into our junk pile of prototypes.

We are doing something very special for the Camaro with this system ,all we ask, is be Patient, we will leak out some pics soon and then some test units will make there way out the back door by the time you are looking at the pictures online.

(added notes)
You will see strong dyno gains in both Torque and HP, but we are focusing on the power under the curve due to the cars weight (3850lbs 1/2 tank of gas)
The aero package is designed around the airspeeds we measured at the mouth of the throttlebody in a specified RPM range for max velocity.

(The "how much power will I gain" question)

I will keep this very simplified so everyone can fallow.

The Ram effect created by the system when in motion pressurizes the intake manifold increasing the natural ram tunning of the intake manifold runners.
Most modern fuel injected cars use ram tunned intake manifolds and these manifolds usualy develop another +1.5 -2lbs of BOOST at the back of the intake valve. ( this is done via wave tunning)


We can usualy make another 1/2 pound in the plenum and 1/2-3/4 at the base of the runner quite easily ( this depends on the intake manifold itself and its fill rate and the motors dynamic displacement) Thats basicaly 425-430 fly hp divided by 14.696 = 29.25hp for every 1 pound of pressure.
( supercharged engines see another 1.5-2PSI of boost as the VR system helps the engine overcome the blower losses)
( the more modifed the engine the more the VR will shine)

Total power gain is as fallows - dyno gains + pressure measured at the base of the intake runner = total gain at "THAT " given road speed. Properly designed ram air systems make power exponentially , so the faster you go ( as long as the aero package supports it ( and the filter flows it) the more power you will make.

Ex- as an example, lets say you gain +15 rear wheel hp sitting static ,no tunning etc.. then add +.5 of pressure ( = +14.6hp) by 37mph = +29.6 hp gain to the rear wheels @ 37mph with NO TUNNING!
by the 1/4 mile that will turn into +33-35 rear wheel hp ,again NO TUNNING!
on a stock motor.

Thats one of the best HP to $$ you will ever buy.

I hope this answers some of your questions.
