VaraRam will give you practically nothing on a dyno. However, it will give you plenty on your 1/4 mile times if you track your car. I do a mod at a time and go to the track. The VaraRam gave me a bunch. Here is my mod progression so far.

Thanks Alot. After another call into The Vette Docs, I will be switching over to the VaraRam. Cajundude, with those nice track numbers what kind of filter are you running with the VaraRam and do you need a velocity stack or not? Also I've seen on the forum the the VaraRam is now shipping with a "new and improved green filter". Any thoughts?

Here is why I think it helps. When you are drag racing the under hood temps are highest just prior to the green light. If you are using a stock air box it will be sucking 100% hot under hood air. If you are using a vararam all the air will be ambient temp because vararam receives all of it's air from outside the hood. No other CAI can do this.
I bet if you guys go check your time slips or data logs you will see a gain in your 60' times. I average 3 tenths faster with a vararam, and it breaks down pretty close to 1 tenth to the 60' and 2 tenths to the end of the qtr mile.

Long waits in the staging area realy bring up underhood temps. I had a RM Twinflow intake and opened the fog light area. I monitor intake temp. via a direct hookup and the intake temps went up as soon as I closed my hood. The temps came down by the end of the run but I lost power(do to higher intake temps.) over the first half of the run. After several failed attemps to get the temps to stay at ambient I switched to a TRAP intake. I ran my best time in 86* ambient with this setup. My previous best was at 60* ambient. I also got my best 60 ft. times.

I'll say this then I'm outta this one. I respect Cajundude and Shurite. But no one has presented any data to support their claims. Jason (Cajundude) has done a good job of documenting his progress. He's forgotten the most important data. Weather. Temp alone means nothing. You need BP, Humidity and DA. DA alone can account for almost .6/.7 loss or gain.
Same goes for Shurite. I know him, he's a friend of mine and he doesn't own a weather station.
The other guys have posted SOP. They don't have a clue of gains or losses. When I was a kid we used to invert the air cleaner cover. You could really hear that engine sucking air and I know it added 100 HP. I could feel it.
You've got an excellent system. You will experience no gain and probably a loss in HP. Good luck to ya and remember I told ya so.

Actually I do not have a weather station but I do keep track of the local weather when I go to the track. So I have good data, I predict my dial in within .03 usually. So I definitely have good enough records to notice a three tenths gain.

They don't go by this 'seat of the pants' crap.
In addition it's lousy construction and lack of filtering capability are detrimental to your cars health.
Hi Gary.
Same issue here in 'Vegas plus it sucks all the dirt off the road. Add to that flash floods and being caught in flooded streets.

Number 1, if I'm not mistaken, the air inlet for the stock air intake setup, or even the vortech/hurricane etc. is from the bottom. Has everyone cleaned out their radiator space lately. I think I found a dead bird! This point is actually lower than the Fog Light cutouts. The difference in distance from the Fog Light cutouts to where the other intakes reside is probably only 8 to 12 inches.
Number 2, water ingestion issue is discussed per this link
