Considerng a snorkle is forcing cold air into the intake, is the any horsepower gain? Obviously if there is can't be more than a few horses but just wondering if anyone knows of any hp gains or experienced it for themself.

This would be good subject to discuss..the way how snorkel mount it just way far back and is it really gain hp? By how much? 5 ? 15? 25? And of course other benefit by mount it high you can drive it thru deep water, but not all of us will drive the 80-s thru water.So whats good about it? The weird looks? The Black long tube? :confused:
 
I doubt that a snorkel will provide any sort of performance gain with a naturally aspirated engine. The primary benefit in such a case is the same reason the snorkel was designed in the first place, IE making the vehicle able to go for a swim....:D

A secondary benefit is the fact that the air inlet is higher up and the level at which it resides seems to be above most road dust.

I believe that a forced induction engine is a totally different animal and in this application the engine benefits from the fact that the air intake flows better and the incomming air is cooler.

In my case I noticed a slightly "crisper" throttle when I fitted the snorkel.

DO NOT get one if the "gawk factor" irritates you 'cuz you gotta tell people what the hell it is all the time...:D
 
When i installed it, I noticed* a "gain" in acceleration when starting at an already high speed, ie accelerating from 50-75 mph. That said, it is certainly not enough reason for a snorkle.


*I very well could have been making this up to myself. :D
 
I doubt there is any gain. There isn't enough air to make a difference. If the cold air factor were sufficient, people in Nevada or similar places would find their cars leaping about at night and crawling daytimes.

After installing my snorkel, the throttle is crisper, especially on really cool, foggy days. I also noticed a huge increase in power similar to that gained when putting V-Tec and TRD stickers on the tailgate.
 
My snorkle didnt give me much of a gain on my 4runner but it did coast smoother on the highway. It has nothing to do with ramair though it is because I have dense cold air from outside the engine bay.
I also dont like the giant tubes all along the fender, escpecially with my future exocage. So I built this, it can be raised to any height in about 5 seconds and it can be rotated to any direction, and it cost me about $20...

Cdan,
I thought that cooler air and better air flow = a better running engine? I wouldn't mind the "gawk factor", I get it from my stunning looks already :beer: ;) l
 
The engine already pulls air from outside the engine bay with the stock setup. The intake is inside of the right fender and there are large air gaps from there to outside air. The air temp difference from this environment to the engine bay is significant. The air temp difference from this area to a snorkel intake is unlikely to be significant except at very low speeds such as wheeling.

As for airflow changes, there is flat no way adding several feet of friction causing tubing will add power. Intake runner lengths are often tuned so that the moving column of air compresses right at the moment the intake valve reopens for another 'breath', but such a long tube would not perform this.

That thing looks weird. Shouldn't it be higher up by the top of the windshield? ::confused:

Is there a big deal if the snorkel does not add HP gains? it is designed for water fording, its just a side effect if there is the cold air, ram effect others are talking about. I think it would be a big deal if you were paying extra for the HP gains when there is none, for me the basic and primary reason people need snorkel is for water fording. If and ever there is HP gains then its just an added bonus for snorkel users, aside from other bonus effects by intstalling the snorkel.
 
I think one thing should be pointed out pretty quick here, and surprised it hasn't allready, but just because you install a snorkle does not mean you can drive through water up to the windows. There are many electrical items that must be addressed before the snorkle even becomes affective in a deep water crossing.

4rnr, i think that's pretty sweet. I love seeing homebrewed items on trucks.

I agree. The snorkle isn't even waterproof what with all the connections, just water resistant. If you want to drive in deep water you need to proof a lot of wiring and holes. That could be very complicated and time consuming.

The snorkle does buy you protection for your intakes from splash. That matters much to deisels and a little bit to gas engines.

From Safari website:

Will installing a Safari snorkel increase the power output of my engine?

This depends in the standard air intake design of your vehicle. All Safari snorkels are designed to flow more cool fresh air than your engine could ever need and this may help the power output. However, the state of tune of your engine, at the time of fitting the Safari snorkel will determine the extent of any possible increase.

is there an art to taking a snorkled LC 'swimming'? IE what about the exhaust? i guess you have to stay on gas throughout the swim, no?

In tests I have done I have found the inner fender air to be just about a hot as the engine compartment it's self, bordering on 180 degrees with the engine at idle on a summer afternoon. Ambient air was in the low 90's.

In addition the little box thingy inside the fender is very restrictive.
