this is a monster of a thread, no way i'm gonna read it all!! Has anybody took their car to a track and saw if there were any significant gains with and without the vipair? I would like to buy one if it does something, but if it doesnt i dont want to waste any money.
If somebody wants to send me one i'll test it at the track and post my results

White hood vents - 15 rwhp
White Vipair - 25 rwhp
White stripes - 10 rwhp
Are you starting to figure this out...?

i was thinking the same thing. I'd like to see how he got it together. I could just see it in person, if I could get the guy to come out to the trackthis requires more pics

Actually I am a member of the Harley Forum (Gun totin' hard talking 1 percenters), the AC Cobra Forum, (Seat of the Pants rocketing into eternity dudes with no safety features at all), Corvette Forum, (What will our cars be worth $$$ post GM?), and now you guys!
You definitely have taken the prize for sheer fun-seeking rib-poking fellowship among a very small and exclusive group of owners. If this thread shows anything it is that Viper peole are FAMILY!

No, actually unless your car is being dyno'd in a wind tunnel, it should be the same as all cars - no improvement. The Vipair is a dynamic device requiring the car to have air movement fore to aft. Like going down the road. Like if your dyno was in a wind tunnel.
A dynamic devise being tested in a static condition is pointless.

Amazing that someone just paid $91 on ebay for one when you can buy them brand new on ebay for $59, as that's what and where I paid for mine.
well now you're making me feel like a big dummy. I bid $90 and got outbid on that one
where can you find them for $59 new? I looked and couldnt find them.

I don't disagree with this statement in general, but I think we could all agree that cooler air makes a gas engine run better
That being said, we have two cars with VECs on them. One with a Vipair, one without. Idling in hot temps, the Vipair car is consistently anywhere from 10-20 degrees cooler on the VEC log. To me, this would sort of indicate that a closed hood dyno run could produce slightly better results due to the temp difference.
I'll never know if it's true cause it's just not at all important to me, but theorectically it would seem the cooler air car should produce more power.
Steve
Have you ever tried switching the Vipair to the other car and seeing if it too idles cooler with the Vipair installed?
this requires more pics

If you're referring to my photo, I don't have any more pics, and it's not on the car anymore

No. Again because it never was too important to know........but now that I've thrown this out there....I'll do it if we ever get another comparable hot day. I would guess that temperature differences should be relative no matter the ambient, but for the purpose of this extremely scientific study, I wouldn't want the test parameters to be too different
This has been a piss poor summer so far up here. Something like 17 degrees below normal hi temps for June I think I heard somewhere. We had one good week of hot and that was it so far. It was borderline turn the furnace on the last couple nights.
The VEC logs under power showed similar temp differentials.

here where you at in Michigan, ever head out to milan, lapeer, or any of the other tracks? I'd definately like to check out your cars and pick up a few pointers!

so does that mean it didn't workIf you're referring to my photo, I don't have any more pics, and it's not on the car anymore

Not necessarily. The car's for sale, so I've taken all of that off.
I can't really attest to it working or not for sure, though for about a week the car was running like a banshee.. until I decided to put the NACA duct back in. As soon as I did, the very next drive, it had somehow lost the added power I'd gained somewhere along the line as I fooled with inlet air and mods under the sills.
Removing the NACA duct again did not bring that awesome power back. There was no doubt about it, even with almost new drag radials on the car, it'd spin the DRs in places where previously it wasnt spinning the OE tires.
It felt like a Roe blower car must feel, just an enormous power gain. Chuck Tator ventured that it might have been timing, but I don't why it'd change back to "normal" just from putting the NACA duct back in - other than the duct backflowing air I suppose. As soon as I took it out of the garage and headed off in 1st gear I could tell the added power was gone. I don't think I was going fast enough to have air backflowing out the NACA duct.
I also had a modded airbox on the inlet side with 4" hoses added , so it's hard to know just what each individual mod was contributing.

Overall, for the average car I tend to think there are more gains to be had on the exhaust side-which automatically helps the inlet side anyway.

that picture makes no sense to me ??
are those dryer hoses pulling in air before the filters?
so your NACA duct was causing a loss in power?
if you were running 4" hoses, what size TBs were you running?

The hoses are from NAPA. Air coming thru them enters the airbox just ahead of the filters. They supplied additional air, about a 50% increase in inlet air area as I recall. Air was still coming in the front of the airbox.
On the one hand it'd seem hard to blame all the power loss on the NACA duct because the car didn't respond immediately to my blocking off the duct opening with the flat cover. But I do know for certain the extra power was lost as soon as I put the NACA duct back in.
TBs are stock size.

well dang, i may just pick up one of these! Depending on how easy they are to install, i may do a back to back run at the 1/4 mile to see if there are any gains.

Just as an FYI, while this thread went back and forth and back and forth about whether the Vipair worked. Serious racers were buying them up. Road racers and drag racers.
Here is a pic of Norm Kroener's car, one of the fastest NA vipers around, the picture kind of says it all.

That's because his car is red sillyhead.

Do you find the white accents speed it up or slow it down on your car?

White is technically a lack of color, so the white vents shouldn't slow him down or speed him up. That said, the all white Vipers don't move at all.
