VaraRam RAM air system updates ?
It’s been a month now with no more updates on the VaraRam RAM air system from the people that have it in their cars. Any news to report?
I noticed that their advertisement in the July Vette magazine offers a performance guarantee: “We guarantee the performance of our products, or we will buy them back!”

Re: VaraRam RAM air system updates ? (Hex29A)
I am going to test one of their units in the next week or so. I made a few passes at HRP to get a baseline ET for my stock car. I will go back to HRP to see how much I can gain in ET and trap speeds. For a system like the Vararam, that's about the only fair way to assess performance. I don't know of any shop dynos that would simulate the performance at speed.
I spoke with Patrick and I am impressed with what I hear. I was holding off an intake change because of what I'd heard about the '02 Z06's and the WOT AFR problems. I am optimistic that the fuel ratios will be better for the Vararam/'02 Z06 combo than with a few of the other intakes.
When I first heard of this system, I was more than a little skeptical. Skeptical enough to do a few calculations on my own. http://forums.corvetteforum.com/zerothread?id=197494 From what I read on the "other" forum (www. Corvetteforum.com), a member was able to record a 2.5 PSI manifold pressure increase over the MTI ram air setup. If I can get anything remotely approaching +2.5 PSI, I will be ecstatic.
At this stage it's all speculation, but hopefully I'll be able to get hard numbers in a week or two. I'll keep you guys posted.

The latest updates to the VR-1B are better shaped scoops and airbox that were created after some further R&D. Also, an optional foam race filter is almost available which will add roughly half a tenth in the 1/4 as well.

I am also interested in this system. Once I can view some hard fast numbers, I can make my decision. To the test mule community, appreciate your sharing your numbers and thanks.

Re: VaraRam RAM air system updates ? (C54FUN)
If the weather holds out for the weekend, and there are no other problems a completely stock 99 C5 A4 will be testing the unit this weekend at Atco. The owner has baseline runs at this track and others so a very good comparison can be made. As the information is relayed to me I will pass it on. We also have other cars lined up to test also, from an A4 with only an X pipe, to a H/C car with a 4400 converter and 4.10 gears & a 408 stroker that has already gone 10.8's while being driven to the track.

Re: VaraRam RAM air system updates ? (Red98C5)
Can I offer you a '98 MN6 lightly modded with baseline numbers for comparison testing? We are in Randolph NJ about 1 hrs. ride from Brick NJ. Plan to attend the challenge series this year as in the past. Please advise if there interest and thanks.

Re: VaraRam RAM air system updates ? (C54FUN)
While track numbers are the ultimate test, you must record temp, humidity, and most important...barometric pressure for the base and modded conditions. Using these numbers you can calculate a corrected number which will be more realistic.....much like the correction factors on the dyno.
Case in point, I ran a best 12.43 and 113 MPH in my C5 Coupe M6 with just a K&N filter that dyno'ed at 320 RWHP.....but it was in optimal weather....
Just food for thought..... :cheers:

Re: VaraRam RAM air system updates ? (REDGAR)
Yes I did, thanks! I actually posted a thank you (4th post, one message above yours :D). I want to see the car at the next Cartek Corvette Challenge. Nothing beats a close up inspection of the real thing.
