Can anyone tell me what difference if any a snorkel will make to a toyota 4500 petrol motor.

Ok a bit more of my department.. :rolleyes:
. As insane said its the water thing for 4x4. As for motors any clean crisp air is always better for petrol/lpg engines. As in cold air inductions on the later model cars Grumpy and forced air induction on performance cars. Fuel buns more eficently hense better performance and better econamy.

Snorkels a are designed primary for deep water crossing but they give other advantages.

- Clean air pickup
- If the intake is facing forward (which is most cases) if assists by forcing air into the filter/motor but that is above 70Km/h
- If the snorkel has a adjustable intake, it can be turned backwards on extreme dirty roads, heavy raid and snow

It is said having a snorkel will help with better economy and power in the highway. Some test prove it and others don't.

Grumpy, here is a list of some benefits..... On a petrol Engine, they do benefit from the colder/more dense incoming air. This does equate to more power, not a lot, but it does work.

5 Reasons why your 4WD needs a snorkel.


1 COOLER OPERATION

Whether your 4WD is powered by a petrol or diesel engine, it's dependent on air for its operation. Fitting a snorkel means the air supply is drawn in at roof level and not the air intake, which is often located in the engine bay. The cooler air stream enhances engine performance due to the cooler air being more dense allowing better combustion and more power.

2 LESS DUST

Because the Airflow Snorkel draws air from roof level, dust isn't as thick and plentiful as it is in the engine bay or inner guard where many engine air intakes are located (if you look under the bonnet after a few kilometres of driving in dust you'll see what we mean!) The relatively cleaner air, via the Airflow Snorkel working with the original air cleaner system, will help extend air filter effectiveness, therefore reducing wear of vital components and leading to extended engine life and reliability.

3 SAFER AND STRESS FREE RIVER CROSSINGS

When crossing streams, rivers or bog holes is not the time you want the engine to die. Diesel engines in particular are very expensive to repair if water should get into them. But with the air supply via a positively sealed Airflow Snorkel well above water level, you can expect worry-free water crossings so you can focus on picking the best and safest route across.

4 RAM AIR EFFECT

Because a snorkel is forced through the air as the vehicle travels, it creates what is known as ram air effect. This has often been found to provide a welcome increase in engine performance.

5 CHEAP INSURANCE

With the average cost of rebuilding a diesel engine being around the $6000.00 and a petrol engine around the $3000.00 can you afford to take a punt next time you cross a river or a bog hole that is “a bit over the wheels” level. Don't risk your engine.

Does this mean you have a snorkel now mate? Sam let you get it?

HE HE HE Sorry had to be said. :D

I do, woohoo, a $345 snorkel turned into a $900 fiasco, but, it is on, and looks great, and it has helped a bit with performance, but, she is still apuffing billy, LOL.

So, what went wrong?

My TEMPER!!!!!

You name it, everything. Ended up having to replace a windscreen, repaint a guard, dent is still there, and a washer bottle still needs replacing.

But, I live and learn. I am thinking of putting it up on the site, members might get a good laugh, and learn what NOT to do......

sounds like a funniest home video but can totally understand the frustration. I have looked at doing the install myself and decided I will to get ARB to do it. May happen after the Brisbane 4x4 show

If you have ALL the right tools, it is not that hard, I had things like the hole saw would not fit in the chuck of my drill, then the battery was flat, so tried to find my spare, and my boys used it to power a scooter..........

Apart from all that, 3 hours, and it was in.

Planning to get the Prado snorkelled next month. Will be interesting to see the changes in economy and power if any.

as far as the average snorkell goes, the local arb or tjm store should be abel to supply for almost any model right?

Installed the safari snorkel on the weekend and it went in ok, no major issues. I did find a whistle noise which came down to the air moving through hole where the pipe goes through the guard. Seals that and now chasing a minor whistle. Not sure if it intake or air moving beteen the snorkel body and the A pillar. Has anyone else had this issue?

Did you end up working out what was causing the whistle?:confused::confused:

I havent noticed any whistles with my new snorkel, but then again, my old girl 60 series is a loud truck, LOL. :eek::eek::D

Might need to see if moving the snorkel further away from the A pillar will fix this. If not, then it could be air trying to get around the bracket.

The whistle was caused by the grill on the ram. I sealed the item onto the ram and no whistle at 110KM/H. It was noticable proir to sealing at 75KM/H.

Hi Grumpy
All of what people have said about the snorkel is true
Unless you have the same lpg system fitted to your landcruiser that I have.
It's an older system than the new ones out today and since i've had the safari snorkel fitted I have to run it with the head facing backwards as I get a ram effect when on gas and the car wont run properly.
However when on petrol I face the head around the normal way and no problems.
I may have to get my gas serviced soon as the cruiser wont idle since I've had snorkel on, but it may need to be tuned up as it could just be running a little lean, I hope.
Other than that no probs.
I did say it was an older gas set up.

Yeah spoke with a bloke the other day and he said mine was fitted with a regulator in the air cleaner to adjust the mixture to suit, but he did say he had to turn his around too.

Since installing the snorkel, I have noticed a improvement in power on the highway and a bit more get up and go around the city. The economy has improved but new plugs have something to do with that also. There is a bit more wind noise but not excessive. Nothing that the radio or the kids screaming in the back can't drown out.

i had fourbys chuck 1 on mine ('92 GQ petrol) Thursday, so i'll keep you all informed as to how it goes. Heading to Levuka at the end of May, so looking forward to diving into some mud without having to think about it too much.
