Its not about power. Its about air flow. We dynoed a vararam and it was veryd restrictive. We removed thw filter and gained hp. Rotofab was decent on the dyno but could be better.
With a rotofab and superchips tune i made 303 hp and 333trq.

Vector did a test between Roto Fab, Vararam and New Era OTR... If I remember correctly on his Dyno on that day the Roto made a little more... I'm not sure which does better a speed since pulls are sometimes done withe hood open ..Open hood would allow a roto to pull more air than it may pull with it closed..
I honestly don't think you can go wrong with any of them ...But if you have future plans beyond simple intake bolt-ons you may want to think before you buy

that is why i am asking, i only like to buy parts once if i can, i am trying to do my research first, as I dont have the unlimited dyno access i used to have back in the day when we used to test all these different parts on my WS6.

All I can say is from my experience is when I switched from a New Era side mount(similar to a Roto) to a Vararam I noticed a difference at high way speeds.. You can pm PatG if he doesn't chime in but he has done some testing on the VR,Roto Fab and Roto Fab with a 102mm maf(big $$$)
Edit: What are your plans for the car?

I didn't know about the RamJet from JHP before buying the vararam that I currently have but I dont know that I would have gone that route any way. Looking at the pricing the vararam is almost $300 less than the Ramjet. But I will say that the Ramjet does look like it is better quality. Think it would have very close to the same dyno numbers though.
IMO the Vararam is worth the money. I picked up 3.5 tenths after putting on my car with no tune. I got mine from Speed Inc for a good price.

The RAMJET filter is bigger and scoops air from a better location, the housing leading to the MAF is bigger allowing more air to flow, etc... The housing is also more rugged and doesnt sag like the Vararam, plus no clips to come open on their own, no weather stripping leaks, etc..

umm right now looking for a CAI, different wheels, tint windows and a tune and maybe headers. Doubting the headers though

The RAMJET is built much better then the Vararam, I also happened to get my RAMJET for $320 so that swayed my decision. I was going to go with the VCM OTR which is pricey too but again worth it. With both the Aussie intakes you get what you pay for, they are extremely well built compared to the US knockoffs and include more parts which help solidify the install. You can instantly tell more engineering went into these designs.

thechef: Good luck with your car. Whatever CAI you go with, all of them have their advantages.

Vararam is nice, but it gives you no growing room for larger MAFs or supercharger in the future. The over the radiator setups are better at bringing in high pressure cool air, but their boxes are more restrictive than the Rotofab style CAIs. I gained a consistent 5 rwhp on my Vararam by removing the filter. I gained 1 mph in the standing mile also by removing the filter. The plenum is too small for a heavy breathing engine. If you're bolt-ons only, all CAIs will be similar in gains (around 10rwhp). If you're heads/cam or blower, the Rotofab would allow you to run a bigger MAF and have less flow restriction.
This was proven over the course of 300+ dyno runs with G8s.

Have you tried the VCM OTR or RAMJET in your testing? Filter is bigger, housing is bigger, basically no bottlenecks the Vararam has.
