Put one around your neck and see if it helps you beath easier!!

It's my understanding that the SEV system doesn't have to be plugged in at all.. it's just a band that you wrap around a tube and it magically works!! ..

And I have also heard that it truely works.. but I'd rather put 750 bucks towards a turbo than on something like this.. I am just waiting for someone to take the plunge..

 

I don't know and havn't got a clue either, but I'm trying to remain neutral and not make fun of, or put down a possibility. If I wasn't skeptical I would have bought it. I want to hear from someone who has experience with it and is not just guessing. Maybe, it works - or why do all these japanesse owners buy it?

 

S2kRob: If the ECU readjusts, won't it "adjust" out any gains from the SEV unit?


cjb80: If it's a non-active item as you mention, I'll claim it's crap until I see dyno numbers from a fellow board member proving otherwise (a member that has nothing to gain would go a LONG way towards helping the SEV's case...not to say Randy has something to gain, I know nothing about him). I want to know how a band of ANYTHING wrapped around the airflow tubes can split O2 molecules. They mention radiation in the English version, but the amount of radiation necessary to split those O2's up at any significant amount would make any of us sterile within a few minutes.

This is like those Homedics bracelets that are nothing but weak magnets wrapped around your wrist...kind of annoying to see people waste their money on those things with claims like "I was cured of Leukemia!" or "It solved my financial issues!"

I think I'm going to create an item for HP gains, attach to it a sheet of info with some halfway intelligent-sounding physics/chem crap, and charge a LOT of money for it...hell, I'll have Michelle paid off in NO time! Who cares if it works or not, it willmake ME money Sorry, I'll let it go now...

 

There is an easy way to test this out...

1) a group from Chitown, SoCal, or Houston (the 3 major congregations of board members) pools up about $1000.
2) 1 member with a broken-in vehicle - over 10K - and unmodified (no SC, no CAI, etc) offers to be guinea pigged, ideally someone who would buy it if it works.
3) dyno the car as-is
4) install the magic device
5) drive for a week or two (settling time or whatever they call it)
6) re-dyno, same place, same dyno, same operator, similar weather if possible (easier in SoCal or houston then chicago).
7) compare results

If the results are justifiable, say more then 3% gain (statistical error of a dyno?), the guinea pig 'buys' the system from the group and keeps it.

If the results prove it's bunk, no individual is out $900-1000 (system + dynos), but each person is out $50-100 depending on how big the group was.

This system keeps coming up as a topic, it's time we proved the thing right or wrong!

 

WSB,

My main question is, why is there a "settling" time required? The system either makes power in the manner mentioned or it doesn't, plain and simple. It is supposed to split O2 molecules up into individual atoms in an amount sigificant enough to change the airflow characteristics of our vehicles. If that's the case, what is there to "settle in"? If it takes so much time to "settle in", does anyone here honestly think it can work fast enough during normal operating runs to make any difference in engine characteristics? I'll admit I could be wrong on this one, but VERY simple logic dictates that, given the facts on hand, these are contradictory statements.

By waiting more than a few minutes between dyno runs you are just begging for differences to show up in the numbers due to atmospheric condition changes. 3% of 240 HP is over 7 HP, so that right there shows any statistical differences will overshadow any real gains claimed by the SEV. If that band changes O2 molecules to O atoms at such a significant rate, I don't want to be near that shipping box! $10 to anyone who wears THAT collar around their wrist and let's me take images for American Physiologist a month from now

 

Snake oil is a charitable estimation. What nonsense, although there are enough crystal channeling vegetarians in Southern California that there may be a market for this scam. Of course, I don't know what I'm talking about, just expressing an opinion and laughing.

 

I don't think "O" will even combust... I believe you need to have 2 atoms for this to work. This has to be a load of crap...and 750 bucks for some little "magical" tape/ring? I don't think so.

Actually O2 won't combust, O will. O2 happens to be the form in which oxygen is stable, and thus found in the atmosphere. During combustion it is actually splitting, with the simplified primary reaction in a gas engine being 2 C8H18 (Octane) + 25 O2 -> 16 CO2 + 18 H2O. The only possibility I can think of off-hand would be that the SEV system is doing something to make the molecules slip by each other with less friction, thereby 'excess airing' the engine - leaning it out. This would in theory reduce incomplete combustion and gain power. But like MacGyver said, anything (logical) that could do this would require power input equal to or greater than the gain.

I'll do some more digging later... time to have fun!

Maybe one of Chemical engineers out there can call them up and get some facts or reverences?
