No it doesn't. It shows that your overall mods/driving/Air quality/track prep worked well. It doesn't show that you couldn't have done as well with a different CAI.

As for the seals Vs. hydrolocking, that just shows that this CAI can and does fail in multiple ways. BAD

 

Do a search on hydroloc... you will see the stock unit does it to so the vette is a bad design or is it idiots driving them, my gains were proven same DA

 

You're wrong on this. There are just too many guys on here over the years that are getting the same results (talking LS2). Go back and read my results, I didn't imagine it. Vararam was the only change I made.

As for the problems, anything improperly installed will give you problems.

 

True.
And that very same "logic" applies to every single other CAI design (or even the factory stock air inlet) out there as well.

Go drive your car through a 6-10 inch deep, 8' x 8' wide puddle at 40+mph and then report back to us on how well your "oh so perfect" set up faired, deal?

 

I read those posts once, but if you feel a review is in order, let's talk.

Christopher's "test" did show gains with the Vararam unit and some tuning changes over a stock LS7 unit with a modded (cut open) shroud on a well tuned 7.0 motor and on an 1/8 th mile track in negative DA.

Those minimal gains are what you could least expect under those conditions with that car. The other end (most expectations) of the performance spectrum would be on a 6.0 motor with a stock intake and tune on a 1/4 mile track in 3000'+ DA. Then all the rest would have gains somewhere in between. Christopher's disappointment was based on gains per dollar, as he is on the least gain part of the curve.

As far as the "ram air" effect data shows, the only information provided was for low speed (~108 mph) on a 7.0 motor at WOT and measured after the TB. Given the Vararam opening size (reduced by the grille bar size and the aerodynamic shape of the car's nose) and the engine displacement and RPM, the math shows the speed was insufficient to record positive pressure.

Next, K&N only provides performance gains because it doesn't filter well. There was no documentation for comparison to the Vararam.

Now onto the hydrolock potential. A person has to understand the limitations and avoid going beyond.
No air/fuel engine is immune if the water is deep enough. It's why submarines shut off the air intake and run on electric power before they submerge.

Just trying to provide some clarity here to the referenced post.

 

Then let's add a little bit more clarity to the post. 108 mph isn't fast enough for the "RAM AIR" to kick in? First, what math are you using? Second, if it kicks in somewhere above 108 that doesn't give you much time or MPH to show 3 tenths gain in performance when the car normally only traps 115-117.

Last, further into the post, JoeG says he logged the MAP at 185 MPH and still got no gain. It it was going to work, it would have by then.

 

Instead of he said she said put one on and tell us what gains you seen or didnt, my gains were within a 10 ft da diference

 

Before we even get to "First", remember that this is on a LS7 car with 3.42 gear and an A6 in 4th gear. A LS2 or LS3 car with different gearing will not yield the same results.

First, the math is that real tough 5th grade stuff, like you can do on a 4 function calculator.

Second, I never said a ram air effect "kicks in", but only said 108 mph was insufficient speed for it to happen under those specific conditions.

Not that it matters much, but Christopher's car normally traps 129 -133.

Last, (for you) I never commented regarding Joe G's car, nor did I address any speed or conditions that a Vararam would produce positive pressure.

Last, (for me) Any "ram air" effect will be minimal even if the inlet were positioned in the most optimum location. I doubt that piece of plastic could be forced through air fast enough to create 2 bar pressures before melting from the friction. The fact that Joe G. recorded a 1.0 MAP at the end of the 1/4 mile, rather than anything negative, speaks volumes about the virtues.

 

I owned pretty much every intake on the market with my C5 and have had three different intakes on my C6. I always come back to one thing...........Vararam.

People can talk about poor build quality.......clear silicone that filter in there, it will seal nicely, then just peel out when you clean it and reapply. There is not a better system out there (IN MY OPINION) if you want the best HP/TQ/Times and no I dont sell them as a vendor but I am a corvette guy and buy and sell ALOT of items for my car.

Again I have been through them all...........twice, but the one that ends up on and stays on the car is the VR.
