Vararam vs. flip tie mod
Right now I have the flip tie mod done, but I was wondering whether or not I would benefit from a Vararam. I don't see how the Vararam could be any more free-flowing than just an open filter with the flip tie mod. The car just has LG Streets right now, but a Ragin Racin Stinger cam is about to go in. It dyno'd at 365/364 last week. Any thoughts?

I've had the zip-tie AND done the flip tie mod.. The vararam hands down had more throttle response and faster acceleration over 60 mph. Went back and forth twice just to make sure, all in the same day! Vararam rocks!!

No comparison between the power of a "zip tie" mod and a vararam, except maybe on a dyno. vararam does not help dyno #s, but makes a BIG difference on the street. A vararam is probably the best performance mod for the money other than N2O

This area sees increased pressure from a ram effect similar to what is experienced with the vararam. I've measured the static pressure at 70 MPH in the vararam housing and the area in front of the radiator with a digital manometer, the results were almost identical.
The increased static pressure from in the ram effect at speed it what provides the increased performance, it does not matter where the increased static pressure to the intake system is provided from (cowl, hood scoop, front valance duct...).

1000%, Just no replacement for the battle tested time proven Vararam as it blows everything else away 0 to 120 mph (not even close)!

OP said "flip tie", which means he is flipping over the filter housing, cutting a hole in the shroud and drawing cold air from the area in front of the radiator.
This area sees increased pressure from a ram effect similar to what is experienced with the vararam. I've measured the static pressure at 70 MPH in the vararam housing and the area in front of the radiator with a digital manometer, the results were almost identical.

My vote is for the vararam based
1. The tremendous amount of hard #s and testimonials (rebelheart for example)
2. My personal experience with the vararam BOTH times I have installed them on a C5
BTW; I have cut a hole in my radiator front shroud to feed my supercharger filter cool air, although I not too concerned with the "static pressure" it might provide

Still think the vararam is far superior due to it's "formed plumbing" hooked directly to the TB as opposed to a filter simply being "exposed" to a "high pressure area"

Hope your comment amount not being concerned about static pressure with a supercharger was a vailed attempt at humor.

I certainly didn't mean to make it a "veiled attempt" because I wanted everyone to get it immediately!!At 10 psi I don't think the "pressurized air" in the area in front of the radiator is going to make much difference.
You simply stated that YOU felt that the vararam wouldn't make much difference over what he had. I stated that I felt it would would make a difference based on multiple post and MY personal experience. Now the OP can take the post and make a decision. That how this forum works
Just take a deep breath and realize other guys have experience in modding these cars as well.

Another Vote for V-ram Although some may think the quality is the best (they have improved and fixed alot of the problems btw)
It's popular for a reason, because it works and perform better. Been proven time and time again here and on other boards.
I used a couple of other aftermarket systems and finally swtiched to vram and have been the happiest with it.

Oh yes I forgot, the multiple post and YOUR valued experinece, that information is much more useful than measuring with a manometer.

Some of us have been doing this a lot longer than "others" that just like to post
, but I guess your manometer trumps 30 plus years of modding AND other members documented results.Idea... Why don't you sell your vararam that you're so unhappy with to the OP, and he can see what he thinks of the increase power he will get, and you can mount your filter beside your "manometer"
OP, didn't mean to get off subject, but you WILL get an great performance increase form the vararam system
