Vararam VR-2B Intake System
Manufacturer claims up to 40 extra hp. Is that anything close to the truth?
What about normal cold air intakes? Are they worth it?
Superchip?
Generally, what is most bang for the buck if you want horsepower increase?

Vararam will give you seat of the pants HP. True ram air add on. Many tests to back up there claim. Headers, cam, gears will give the most for the buck. Opinions very sharply. $00.02 worth.

Not native english speaking and not entirely proficient on all those tune options...
What are headers, cam, gears, and what do you mean with $00.02 worth?

Headers = long tube headers, they replace the manifolds that hook to the engine and are the first part of the exhaust system.
Cam= is the brain of the engine, it determines how the valves open/close. It goes in the center of the engine block, it is a long tubular piece of metal with lobes(cams) on it.
Gears= are the gears in the rear differential of the car. If you get a higher numerical number 4.10, it will be quicker of the line than say a 3.42, but reduce your top speed some.
$.02= means he is giving his 2 cents worth, meaning that is what he believes, but it is only worth 2 cents because it is just his opinion and it is free advice, so take it for what it is worth....$0.02

Well, it wasn't my intention to slap anybody here...
I apologize if I made it sound like that.
Thanks for the good advice. I might try it this summer

Question on testing the extra hp
As far as I understand, Vararam works by ramming the air into the engine, and that will only work on high velocities.
So, how is that tested on a dyno?
Maybe, it's only an estimate from improved 1/4 mile runs...

Hi MOL -
The VR setup will get you some HP - and there are many here who swear by it. all these folks can't be wrong...
I have a Halltech TRAP, and although any HP gains achieved with it have not been measured as yet, it did seem to perk it up some...It was not cheap though.
Either system will work for you, and both are offered for sale by forum vendors.
As far as bang for the buck - a head/cam/header will set you back some sizeable ching ($$$) at least in my book - figure probably $4k on the low side.
I thought that the best HP increase and "feel at the wheel" improvement that I acheived on my Z was the LS1 Edit by Breathless Performance.
It was around $300-400 and it made an immediate seat of the pants improvment, not to mention a dyno proven HP increase at the rear wheels of around 18hp on my Z.
I'll add my two cents to Slongs - now you have 4 cents worth of free advice...
Best Regards -

ooooooohboy.....that opens up another can of worms thread.....
There has been much debate in the past on this board and others about the validity of ram-air claims (i.e. negative intake tract pressures) by the VR and any other "ram air" system.
One side says no way at subsonic speeds, the other side says "Way, dude...I get ram air effect..."
I say, the VR does improve performance for many here - and that is all I need to know.

Check out the link above and you'll see many have gained in the quarter with before and after runs. I think this is were you'll really see the gains, the strip, as it is hard to prove on dyno. i did a lot of research on which set-up and it allways came back to Vararam as the leader in gains in the quarter, so it was my choice. Cooler denser air equals power, period. A lot of the '04 z06's throw lean codes after install, another fact that says more dense cool air is entering over stock under hood temps. There are certainly others that work better over stock, but many believe the Vararam to be even a little better.
