Google Ram Air Myth. I thought the same thing. It even seems logical. But after some reading the truth comes out. I can't recall the facts accurately so you'll have to do the reading. It will open your eyes and change your views.

 

Each to their own. Why should I have to clean up their mess? I figured if this is the way it was sent out, Vararam themselves weren't exactly proud of their own product. Fortunately, I was able to sell it.

I agree. I'm somewhat content with my unit, but if I had to do it all over again I'd get the blackwing or some other product that's cheaper/easier to install.

What they send you should not require reworking and modification of any sort. Especially considering the price for what you get. Knock that sucker down to $200 bucks and I'd be jumping for joy to fix it up a little bit.

 

Turbulence in air intakes as well may cause problems too. double intake vs single intake

Most ppl go from a stock air box to brand X CAI. WOW their times drop the cars performance goes UP. so they swear that Brand X CIA is the best thing going.

Then when one starts to switch CAI, Brand X to Brand Y or Brand A and starts doing some comparisons, there may be some but not too much difference.

if a certain CAI works for you GREAT. Stick with it.

I would like to see a short, very short CAI, from the TB out the hood. But on an aerodynamic car as the vette, not sure how that would be??

The Ferrari 550 and 575 have this design.

 

 

I measured the differences in static pressure at the air bridge with a digital manometer under the same conditions (speed, gear, load, ambient temp...) between the factory air cleaner and the Vararam.
With the factory air cleaner assembly, the air bridge pressure varied just above or below atmospheric pressure by +/- 2" of water. With the Vararam installed, the pressure in the air bridge increased to approximatly 12 -14" of water above atmospheric pressure. It's not a turbo-charger or a blower, but it does work.

 

Yeah compared to the stock intake.....absolutely!


The issue is.....and many have said it before....that the vararam isn't really that much better than any other aftermarket intake....and I think the forum here actually thinks that the overpriced, vette taxed, callaway honker is by far the best one to get.

That being said....JW Motoring has some pretty good deals on the vararam and the air bridge.

I'm very happy with my FIPK and it definitely sucks cold air thru the opening in the shroud.

I would have got the Vararam however with the z06 screens it pretty much requires and the additional cost for the air bridge...the FIPK was actually a cheaper bet...and it does a wonderful job for the price.

 

Plus several of us are working with aerodynamic improvements. putting duct tape over the Z06 Screens makes a difference:

1, decreases lift - the engine bay no longer acts as a parachute.
2. Decreasing aerodynamic drag. More wind tunnel is scheduled for fall.

 

well all I can really add is from more an everyday joe or common sense approach. The example above about sticking your
hand out the window at 70. I did a similar but more complex test. I got up to 80 and had a piece of hose basically the sam
port size as the vararam uses and stuck it out the window and ran the hose into the cabin of the car and then put my hand
in front of the opposite end just to see how much actual air was caught and thus "ram air'd" or forced through the hose.
It wasn't a supercharger or anything but definitely I could see some benefit over say just the car moving and getting indirect
air from under the car. I used this principle on my C4 to make a custom ram air intake. It served 2 purposes....to introduce
more cooler air directly to the air filter and also to bring more cooler air into the engine compartment to cool things down.
Worked like a charm on my C4. The only downside...the engine seemed to get dirtier quicker from the additional airflow.

For my C5 I bought the vararam at the special price of $250 shipped when that was the current deal. Mine fit pretty darn
well and I didn't see the huge gaps that were posted above. My only question/concern to the gaps posted in the picture
above is....how much performance are you really actually losing from the unit having the small gaps? I mean this is not a
supercharger so even if there was a small leak the majority of the air would still be making it perfectly fine to the TB as the
engine sucks the air towards it like a vaccuum not pushing it away.
I mean if it were a completely 100% sealed unit like a supercharger then yes...by all means, a small leak like that would be
severely detrimental, but for the vararam...I dunno...I don't think it would matter much.

 

Black duct tape those gaps

 

I'm guessing toyota, I bet this thing sounds fantastic! is that a turbo swift 1.3 on the wall

 

Here's a way old thread for you. http://forums.corvetteforum.com/c5-t...tml?forum_id=1

 

Ilmore - IRL engine branded for who ever is the IRL engine sponsor that year

 

The actual product you get is a piece of crap,cheap plastic ,shoody assembly,poor fitment ,so why buy? very simple they said 3/10's in the quarter and thats what I got. I've paid more for less performance in the past . Ram air IMO load of BS cool air less restrictive air filter thats where perf. increase comes from. you think air is being "rammed" into engine faster than engine is pullingair in at say 6000 rpm?try this rev the engine to say 2500 rpm put your hand over the intake tract and see the force generated by the pumping action of the engine. maybe @ 200-300 mph some ram effect.If there was some ram the car would probablly go lean this happened to some formular cars when they had large bell mouth scoops high up in the air stream and when those same scoops were used in drag cars some cars were getting some pops (lean)crossing the finish line.the speed we go ,the location of of air intake ram air IMO I doubt it

 

This whole subject of ram air or not is getting a little silly. A prime example, if you have your car cruising down the highway at say 70 miles per hour with the stock air inlet and I change to a Vararam what can I expect to happen? Do you think I will get better fuel economy, will the car slow down, will the car speed up?

The fact of the matter the throttle plate sets the amount of air into the engine to produce the power needed to keep it rolling down the road at 70 mph. Changing anything from stock to increase the pressure in front of the throttle plate will change little or nothing. The ONLY area of operation you might see an advantage is at or near wide open throttle.

How much time do you spend at WOT around town? More important to me around town or normal driving is to keep dirt out of the air inlet system. Not much out there will do a better job than a stock inlet system for dirt control. Just my 2 cents

 

people buy this for performance, not for just putzing around. why do heads/cam/blower etc. it doesn't make a great deal of difference at part throttle. Hell, why not get a prius then....

 

I agree with Eric. You might, however, see a little quicker throttle response with a Vararam. The thing I liked most about its design is that is sucks in cooler air from an area that really does not provide any other benefit. It's fairly isolated from the warmer engine. I swapped from the blackwing and noticed a difference in responsiveness (but only seat of the pants so it could be debated) but I did get another .3 at the track as well (different night so it could be explained away). In the end I didn't care. I like the design and the fact that it drew its air from the foglight area. Everybody's reasoning and tolerance will be a little different (just get started on drilled rotors! ).

 

This topic has a life of its own. Every year or two since the Veraram was introduced someone starts a passionate thread about how much faster it is with the Veraram. Several topics ago an aeronautical calculated that you gained 3/4 hp at 70 mph, 4 hp at 150 mph and gobs and gobs if you could make it to 300 mph. Also, he calculated that because of the aero package of the C5 front end, the vents the Veraram was using became negative at about 130 mph and also,big cu.in engines ran out of air at upper rpms. What the Veraram does, and it does it very well, is give you ambient air temps in the low rpm range. This means those who are accelerating with a veraram are getting a more dense intake of air at the slowest speeds and are thus accelerating faster. It also explains why the C5R/C6R were bottom breathers--cool dense air, no frontal air boundries, and ample volume of air for a large cube engine. Me, I don't know anything but some people I know are pretty smart.

 

hmmmm ummmm maybe it is just me...but isn't what you saying half way through contradictory to the other half? lol Sorry I don't follow at all.

 

Both the C5r and the C6R were FRONT breathes. Double air intakes, one on each side of the front screens into the double Kinsler IR intake on top of the engine.

The Splitters kept any and just about all air from going underneath the race car.
