Thx.

P.S. pompous (and others) put at least some basic info about your car in the sig so that all others can place your posts in some context.

Hi,
The Snorkel is a Noise Abatement Device designed for ROW models, principally Switzerland, but with an eye toward more governments enacting similar legislation.
There are really no negative consequences to removing it beyond losing it's silencing effect.
It can be reinstalled. Some have more difficulty doing this than others. I reinstalled mine at the time I removed it, just to see, and I didn't have any trouble at all...
Happy Motoring!... Jim'99

I have been thinking about installing a fire extinguisher as well. Jim, in the case of an engine fire, how would you get the extinguisher to it in time to do any good?

FWIW--
3 full years, daily driver, 30,000 miles in chicago weather (including all winters) and have never had a problem with my car being de-snorked. Everybody should do it!

Today I tried yet again to de-snorkel but I still can't get the blind off. What am I doing wrong? It's gonna break if I push any harder.

definitive
didn't someone dyno this and conclusively put an end to the hp gain/no gain question?
The member's handle was Bussmati or something??

Good thread. I think I might de-snorkle my Box this weekend.

Hi,
Haha, close. And, it was anything but conclusive!
Bisimoto got a bigger graph and went with it, but I strongly suspect (READ Know) that his methodology was flawed and his results well within the error of probability.
He didn't account for Alternator Load. He ran his Baseline COLD and his Test Run HOT. Didn't have a proper Cooling Fan. I suspect he used Correction Software, which is usually an average of averages - inaccurate. And I suspect his Weather Correction was Software-based and not from an actual Weather Station in his Garage. He took his numbers from a Run through all the Gears, not just the conclusive 4th Gear only where the Gearing makes the ratio of Rear Axle/Crank Rotation almost 1:1, and on and on.
All these things have their effect. Adding 1% error here and a couple % error there and pretty soon, you accumulate error equal to, or in excess of, any reported gain.
People will believe what they want to hear (Placebo Effect). Bisimoto is the only person to report a gain by de-snorkelling (in both HP and Torque), in the Known Universe. So for those who want it to be so, it is so.
But, this falls far short of a properly conducted test and I for one remain unconvinced. The only thing which is conclusive here is the old addage: Garbage IN ... Garbage OUT...
Happy Motoring!... Jim'99
